Building on the promise of emerging therapies to deploy the body’s “natural killer” immune cells to fight cancer, researchers at the University of Michigan Rogel Cancer Center and U-M College of Engineering have gone one step further.

They’ve developed what is believed to be the first systematic way to catch natural killer cells and get them to release cancer-killing packets called exosomes. These nano-scale exosomes are thousands of times smaller than natural killer cells — or NK cells for short — and thus better able to penetrate cancer cells’ defenses.

A proof-of-concept study in blood samples from five patients with non-small cell lung cancer demonstrated that the approach was able to capture natural killer cells on a microfluidic chip and use them to “farm” the NK exosomes.

The multidisciplinary team, which included U-M engineers and oncologists, further demonstrated that the exosomes could effectively kill circulating tumor cells in cell cultures, according to findings published in Advanced Science.

“Exosomes are small sacs of proteins and other molecules that are naturally released by almost every type of cell in the body,” says Yoon-Tae Kang, Ph.D., a research fellow in chemical engineering and co-lead author of the study. “In this case, we wanted to expand our understanding of NK exosomes and try to harness their cancer-killing potential.”

Compared to NK cells, NK exosomes are more stable and easier to modify for therapeutic purposes, he says. The system also has potential to help diagnose and monitor cancer, the study notes.

Harnessing the power of NK cells has long presented a tantalizing possibility for researchers. Unlike T cells, NK cells don’t have to be primed by invader-specific antigens in order to fight off intruders.

“One major bottleneck of NK cell-based therapies, however, is that after the injection of the NK cells into patients, they’re not good at infiltrating into the tumor microenvironment,” says co-lead author Zeqi Niu, a doctoral student in chemical engineering. “The NK cell-derived exosomes contain the same cancer-killing molecules but they’re much, much smaller and better able to penetrate into the tumors.”

The technology

While a small number of previous studies had examined NK exosomes’ ability to kill cancer cells, there hadn’t been a systematic approach to capturing patient-derived NK cells and using them to generate NK exosomes, adds co-senior study author, Sunitha Nagrath, Ph.D., an associate professor of chemical engineering at U-M and member of the Rogel Cancer Center.

“The advantage of exosomes is that they’re organic, native to your body,” she says. “We didn’t have to fabricate them. The beauty of the approach is being able to capture the NK cells on a microfluidic chip, incubate them on the chip for a short period of time and then collect the exosomes that are released by the cells. Otherwise, trying to isolate exosomes directly from the blood would be like looking for tiny pebbles in a room packed full of stuff.”

The NK exosome harvesting system combines three technologies. First, the researchers captured the NK cells on a graphene oxide microfluidic chip developed at U-M. Then the cells are incubated, prompting them to release exosomes. The exosomes are captured by tiny magnetic beads, called ExoBeads, which are coated with exosome-specific antibodies; the beads are removed from the chip and the NK exosomes are separated from them using a different process. Simultaneously, the team used a liquid biopsy system called Labyrinth, which was also developed at U-M, to isolate circulating tumor cells from patient blood samples to evaluate correlations between NK cells and exosomes, and circulating tumor cells.

These early stage research efforts examined samples from five patients with lung cancer and two healthy controls.

“What we found was that the more NK cells were present in the sample, the fewer circulating tumor cells there were,” Niu says. “We also found that the more tumor cells were in a sample, the more NK exosomes were present — which is a clue that the presence of the cancer is stimulating the NK cells to produce the cancer-fighting exosomes.”

Additional experiments showed that NK exosomes derived from patient samples were indeed able to kill circulating tumor cells in cell cultures.

A circulating tumor cell is one that has broken away from a primary tumor and begun traveling through the bloodstream. These can then seed new cancers elsewhere in the body through a process known as metastasis.

“When we first started on this research, we weren’t sure if we were going to be able to generate and harvest the NK exosomes using a chip and ExoBeads,” Nagrath says. “Or if we’d be able to collect them efficiently enough for potential therapeutic use. The NK cell capture process, the process of separating the NK exosomes from the beads, creating an assay to evaluate the exosomes’ ability to kill cancer cells — there were many components that had to be optimized for this approach to be a success, and each one presented its own challenges.”

Exosomes also have good potential to be further engineered and optimized to be more potent and efficient against cancer cells, the researchers note.

Next steps

Additional validation and work will be needed to develop the technology toward potential future clinical use, Kang says.

The number of patient samples included in the study was limited by the exigencies of the COVID-19 pandemic, which resulted in temporary laboratory closures across the U-M campus. The researchers plan to continue the work with a larger number of patient samples. They’re also working with collaborators to test the efficacy of the exosomes against tumors in vivo — in mouse models of cancer.

Additional work is being done on the use of the technology to capture immune cells from the blood to provide doctors with additional information about a patient’s cancer. This would be different from most liquid biopsy technology, which focuses on capturing and evaluating the circulating tumor cells.

The researchers also stressed the centrality of the collaboration between physicians and engineers in moving the research forward.

“Immunotherapy approaches that target immune checkpoints have revolutionized cancer therapy for several cancers. However, only a small minority of patients exhibit a durable clinical benefit and cure,” says co-senior author Nithya Ramnath, MBBS, an oncologist and professor of internal medicine at Michigan Medicine. “Preliminary studies with NK cells either by themselves or in combination with immune checkpoint inhibitors have, however, have shown only modest results. NK-derived exosomes, on the other hand, are able to home into tumors more effectively. The current paper represents a technological advance in the ability to harvest not only NK cells, but also NK derived exosomes that could help inform future immunotherapeutic approaches.”

"I Can't Even Save": Americans Are Getting Absolutely Crushed Under Enormous Debt Load

While Joe Biden insists that Americans are doing great - suggesting in his State of the Union Address last week that "our economy is the envy of the world," Americans are being absolutely crushed by inflation (which the Biden admin blames on 'shrinkflation' and 'corporate greed'), and of course - crippling debt.

The signs are obvious. Last week we noted that banks' charge-offs are accelerating, and are now above pre-pandemic levels.

...and leading this increase are credit card loans - with delinquencies that haven't been this high since Q3 2011.

On top of that, while credit cards and nonfarm, nonresidential commercial real estate loans drove the quarterly increase in the noncurrent rate, residential mortgages drove the quarterly increase in the share of loans 30-89 days past due.

And while Biden and crew can spin all they want, an average of polls from RealClear Politics shows that just 40% of people approve of Biden's handling of the economy.

Crushed

On Friday, Bloomberg dug deeper into the effects of Biden's "envious" economy on Americans - specifically, how massive debt loads (credit cards and auto loans especially) are absolutely crushing people.

Two years after the Federal Reserve began hiking interest rates to tame prices, delinquency rates on credit cards and auto loans are the highest in more than a decade. For the first time on record, interest payments on those and other non-mortgage debts are as big a financial burden for US households as mortgage interest payments.

According to the report, this presents a difficult reality for millions of consumers who drive the US economy - "The era of high borrowing costs — however necessary to slow price increases — has a sting of its own that many families may feel for years to come, especially the ones that haven’t locked in cheap home loans."

The Fed, meanwhile, doesn't appear poised to cut rates until later this year.

According to a February paper from IMF and Harvard, the recent high cost of borrowing - something which isn't reflected in inflation figures, is at the heart of lackluster consumer sentiment despite inflation having moderated and a job market which has recovered (thanks to job gains almost entirely enjoyed by immigrants).

In short, the debt burden has made life under President Biden a constant struggle throughout America.

"I’m making the most money I've ever made, and I’m still living paycheck to paycheck," 40-year-old Denver resident Nikki Cimino told Bloomberg. Cimino is carrying a monthly mortgage of $1,650, and has $4,000 in credit card debt following a 2020 divorce.

"There's this wild disconnect between what people are experiencing and what economists are experiencing."

What's more, according to Wells Fargo, families have taken on debt at a comparatively fast rate - no doubt to sustain the same lifestyle as low rates and pandemic-era stimmies provided. In fact, it only took four years for households to set a record new debt level after paying down borrowings in 2021 when interest rates were near zero. 

Meanwhile, that increased debt load is exacerbated by credit card interest rates that have climbed to a record 22%, according to the Fed.

[P]art of the reason some Americans were able to take on a substantial load of non-mortgage debt is because they’d locked in home loans at ultra-low rates, leaving room on their balance sheets for other types of borrowing. The effective rate of interest on US mortgage debt was just 3.8% at the end of last year.

Yet the loans and interest payments can be a significant strain that shapes families’ spending choices. -Bloomberg

And of course, the highest-interest debt (credit cards) is hurting lower-income households the most, as tends to be the case.

The lowest earners also understandably had the biggest increase in credit card delinquencies.

"Many consumers are levered to the hilt — maxed out on debt and barely keeping their heads above water," Allan Schweitzer, a portfolio manager at credit-focused investment firm Beach Point Capital Management told Bloomberg. "They can dog paddle, if you will, but any uptick in unemployment or worsening of the economy could drive a pretty significant spike in defaults."

"We had more money when Trump was president," said Denise Nierzwicki, 69. She and her 72-year-old husband Paul have around $20,000 in debt spread across multiple cards - all of which have interest rates above 20%.

During the pandemic, Denise lost her job and a business deal for a bar they owned in their hometown of Lexington, Kentucky. While they applied for Social Security to ease the pain, Denise is now working 50 hours a week at a restaurant. Despite this, they're barely scraping enough money together to service their debt.

The couple blames Biden for what they see as a gloomy economy and plans to vote for the Republican candidate in November. Denise routinely voted for Democrats up until about 2010, when she grew dissatisfied with Barack Obama’s economic stances, she said. Now, she supports Donald Trump because he lowered taxes and because of his policies on immigration. -Bloomberg

Meanwhile there's student loans - which are not able to be discharged in bankruptcy.

"I can't even save, I don't have a savings account," said 29-year-old in Columbus, Ohio resident Brittany Walling - who has around $80,000 in federal student loans, $20,000 in private debt from her undergraduate and graduate degrees, and $6,000 in credit card debt she accumulated over a six-month stretch in 2022 while she was unemployed.

"I just know that a lot of people are struggling, and things need to change," she told the outlet.

The only silver lining of note, according to Bloomberg, is that broad wage gains resulting in large paychecks has made it easier for people to throw money at credit card bills.

Yet, according to Wells Fargo economist Shannon Grein, "As rates rose in 2023, we avoided a slowdown due to spending that was very much tied to easy access to credit ... Now, credit has become harder to come by and more expensive."

According to Grein, the change has posed "a significant headwind to consumption."

Then there's the election

"Maybe the Fed is done hiking, but as long as rates stay on hold, you still have a passive tightening effect flowing down to the consumer and being exerted on the economy," she continued. "Those household dynamics are going to be a factor in the election this year."

Meanwhile, swing-state voters in a February Bloomberg/Morning Consult poll said they trust Trump more than Biden on interest rates and personal debt.

Reverberations

These 'headwinds' have M3 Partners' Moshin Meghji concerned.

"Any tightening there immediately hits the top line of companies," he said, noting that for heavily indebted companies that took on debt during years of easy borrowing, "there's no easy fix."

MIAMI, FLORIDA (March 15, 2024) – The public health toll from bereavement is well-documented in the medical literature, with bereaved persons at greater risk for many adverse outcomes, including mental health challenges, decreased quality of life, health care neglect, cancer, heart disease, suicide, and death. Now, in a paper published in The Lancet Public Health, researchers sound a clarion call for greater investment, at both the community and institutional level, in establishing support for grief-related suffering.

MIAMI, FLORIDA (March 15, 2024) – The public health toll from bereavement is well-documented in the medical literature, with bereaved persons at greater risk for many adverse outcomes, including mental health challenges, decreased quality of life, health care neglect, cancer, heart disease, suicide, and death. Now, in a paper published in The Lancet Public Health, researchers sound a clarion call for greater investment, at both the community and institutional level, in establishing support for grief-related suffering.

The authors emphasized that increased mortality worldwide caused by the COVID-19 pandemic, suicide, drug overdose, homicide, armed conflict, and terrorism have accelerated the urgency for national- and global-level frameworks to strengthen the provision of sustainable and accessible bereavement care. Unfortunately, current national and global investment in bereavement support services is woefully inadequate to address this growing public health crisis, said researchers with Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine and collaborating organizations.  

They proposed a model for transitional care that involves firmly establishing bereavement support services within healthcare organizations to ensure continuity of family-centered care while bolstering community-based support through development of “compassionate communities” and a grief-informed workforce. The model highlights the responsibility of the health system to build bridges to the community that can help grievers feel held as they transition.   

The Center for the Advancement of Bereavement Care at Sylvester is advocating for precisely this model of transitional care. Wendy G. Lichtenthal, PhD, FT, FAPOS, who is Founding Director of the new Center and associate professor of public health sciences at the Miller School, noted, “We need a paradigm shift in how healthcare professionals, institutions, and systems view bereavement care. Sylvester is leading the way by investing in the establishment of this Center, which is the first to focus on bringing the transitional bereavement care model to life.”

What further distinguishes the Center is its roots in bereavement science, advancing care approaches that are both grounded in research and community-engaged.  

The authors focused on palliative care, which strives to provide a holistic approach to minimize suffering for seriously ill patients and their families, as one area where improvements are critically needed. They referenced groundbreaking reports of the Lancet Commissions on the value of global access to palliative care and pain relief that highlighted the “undeniable need for improved bereavement care delivery infrastructure.” One of those reports acknowledged that bereavement has been overlooked and called for reprioritizing social determinants of death, dying, and grief.

“Palliative care should culminate with bereavement care, both in theory and in practice,” explained Lichtenthal, who is the article’s corresponding author. “Yet, bereavement care often is under-resourced and beset with access inequities.”

Transitional bereavement care model

So, how do health systems and communities prioritize bereavement services to ensure that no bereaved individual goes without needed support? The transitional bereavement care model offers a roadmap.

“We must reposition bereavement care from an afterthought to a public health priority. Transitional bereavement care is necessary to bridge the gap in offerings between healthcare organizations and community-based bereavement services,” Lichtenthal said. “Our model calls for health systems to shore up the quality and availability of their offerings, but also recognizes that resources for bereavement care within a given healthcare institution are finite, emphasizing the need to help build communities’ capacity to support grievers.”

Key to the model, she added, is the bolstering of community-based support through development of “compassionate communities” and “upskilling” of professional services to assist those with more substantial bereavement-support needs.

The model contains these pillars:

  • Preventive bereavement care –healthcare teams engage in bereavement-conscious practices, and compassionate communities are mindful of the emotional and practical needs of dying patients’ families.
  • Ownership of bereavement care – institutions provide bereavement education for staff, risk screenings for families, outreach and counseling or grief support. Communities establish bereavement centers and “champions” to provide bereavement care at workplaces, schools, places of worship or care facilities.
  • Resource allocation for bereavement care – dedicated personnel offer universal outreach, and bereaved stakeholders provide input to identify community barriers and needed resources.
  • Upskilling of support providers – Bereavement education is integrated into training programs for health professionals, and institutions offer dedicated grief specialists. Communities have trained, accessible bereavement specialists who provide support and are educated in how to best support bereaved individuals, increasing their grief literacy.
  • Evidence-based care – bereavement care is evidence-based and features effective grief assessments, interventions, and training programs. Compassionate communities remain mindful of bereavement care needs.

Lichtenthal said the new Center will strive to materialize these pillars and aims to serve as a global model for other health organizations. She hopes the paper’s recommendations “will cultivate a bereavement-conscious and grief-informed workforce as well as grief-literate, compassionate communities and health systems that prioritize bereavement as a vital part of ethical healthcare.”

“This paper is calling for healthcare institutions to respond to their duty to care for the family beyond patients’ deaths. By investing in the creation of the Center for the Advancement of Bereavement Care, Sylvester is answering this call,” Lichtenthal said.

Copper Soars, Iron Ore Tumbles As Goldman Says "Copper's Time Is Now"

After languishing for the past two years in a tight range despite recurring speculation about declining global supply, copper has finally broken out, surging to the highest price in the past year, just shy of $9,000 a ton as supply cuts hit the market; At the same time the price of the world's "other" most important mined commodity has diverged, as iron ore has tumbled amid growing demand headwinds out of China's comatose housing sector where not even ghost cities are being built any more.

Copper surged almost 5% this week, ending a months-long spell of inertia, as investors focused on risks to supply at various global mines and smelters. As Bloomberg adds, traders also warmed to the idea that the worst of a global downturn is in the past, particularly for metals like copper that are increasingly used in electric vehicles and renewables.

Yet the commodity crash of recent years is hardly over, as signs of the headwinds in traditional industrial sectors are still all too obvious in the iron ore market, where futures fell below $100 a ton for the first time in seven months on Friday as investors bet that China’s years-long property crisis will run through 2024, keeping a lid on demand.

Indeed, while the mood surrounding copper has turned almost euphoric, sentiment on iron ore has soured since the conclusion of the latest National People’s Congress in Beijing, where the CCP set a 5% goal for economic growth, but offered few new measures that would boost infrastructure or other construction-intensive sectors.

As a result, the main steelmaking ingredient has shed more than 30% since early January as hopes of a meaningful revival in construction activity faded. Loss-making steel mills are buying less ore, and stockpiles are piling up at Chinese ports. The latest drop will embolden those who believe that the effects of President Xi Jinping’s property crackdown still have significant room to run, and that last year’s rally in iron ore may have been a false dawn.

Meanwhile, as Bloomberg notes, on Friday there were fresh signs that weakness in China’s industrial economy is hitting the copper market too, with stockpiles tracked by the Shanghai Futures Exchange surging to the highest level since the early days of the pandemic. The hope is that headwinds in traditional industrial areas will be offset by an ongoing surge in usage in electric vehicles and renewables.

And while industrial conditions in Europe and the US also look soft, there’s growing optimism about copper usage in India, where rising investment has helped fuel blowout growth rates of more than 8% — making it the fastest-growing major economy.

In any case, with the demand side of the equation still questionable, the main catalyst behind copper’s powerful rally is an unexpected tightening in global mine supplies, driven mainly by last year’s closure of a giant mine in Panama (discussed here), but there are also growing worries about output in Zambia, which is facing an El Niño-induced power crisis.

On Wednesday, copper prices jumped on huge volumes after smelters in China held a crisis meeting on how to cope with a sharp drop in processing fees following disruptions to supplies of mined ore. The group stopped short of coordinated production cuts, but pledged to re-arrange maintenance work, reduce runs and delay the startup of new projects. In the coming weeks investors will be watching Shanghai exchange inventories closely to gauge both the strength of demand and the extent of any capacity curtailments.

“The increase in SHFE stockpiles has been bigger than we’d anticipated, but we expect to see them coming down over the next few weeks,” Colin Hamilton, managing director for commodities research at BMO Capital Markets, said by phone. “If the pace of the inventory builds doesn’t start to slow, investors will start to question whether smelters are actually cutting and whether the impact of weak construction activity is starting to weigh more heavily on the market.”

* * *

Few have been as happy with the recent surge in copper prices as Goldman's commodity team, where copper has long been a preferred trade (even if it may have cost the former team head Jeff Currie his job due to his unbridled enthusiasm for copper in the past two years which saw many hedge fund clients suffer major losses).

As Goldman's Nicholas Snowdon writes in a note titled "Copper's time is now" (available to pro subscribers in the usual place)...

... there has been a "turn in the industrial cycle." Specifically according to the Goldman analyst, after a prolonged downturn, "incremental evidence now points to a bottoming out in the industrial cycle, with the global manufacturing PMI in expansion for the first time since September 2022." As a result, Goldman now expects copper to rise to $10,000/t by year-end and then $12,000/t by end of Q1-25.’

Here are the details:

Previous inflexions in global manufacturing cycles have been associated with subsequent sustained industrial metals upside, with copper and aluminium rising on average 25% and 9% over the next 12 months. Whilst seasonal surpluses have so far limited a tightening alignment at a micro level, we expect deficit inflexions to play out from quarter end, particularly for metals with severe supply binds. Supplemented by the influence of anticipated Fed easing ahead in a non-recessionary growth setting, another historically positive performance factor for metals, this should support further upside ahead with copper the headline act in this regard.

Goldman then turns to what it calls China's "green policy put":

Much of the recent focus on the “Two Sessions” event centred on the lack of significant broad stimulus, and in particular the limited property support. In our view it would be wrong – just as in 2022 and 2023 – to assume that this will result in weak onshore metals demand. Beijing’s emphasis on rapid growth in the metals intensive green economy, as an offset to property declines, continues to act as a policy put for green metals demand. After last year’s strong trends, evidence year-to-date is again supportive with aluminium and copper apparent demand rising 17% and 12% y/y respectively. Moreover, the potential for a ‘cash for clunkers’ initiative could provide meaningful right tail risk to that healthy demand base case. Yet there are also clear metal losers in this divergent policy setting, with ongoing pressure on property related steel demand generating recent sharp iron ore downside.

Meanwhile, Snowdon believes that the driver behind Goldman's long-running bullish view on copper - a global supply shock - continues:

Copper’s supply shock progresses. The metal with most significant upside potential is copper, in our view. The supply shock which began with aggressive concentrate destocking and then sharp mine supply downgrades last year, has now advanced to an increasing bind on metal production, as reflected in this week's China smelter supply rationing signal. With continued positive momentum in China's copper demand, a healthy refined import trend should generate a substantial ex-China refined deficit this year. With LME stocks having halved from Q4 peak, China’s imminent seasonal demand inflection should accelerate a path into extreme tightness by H2. Structural supply underinvestment, best reflected in peak mine supply we expect next year, implies that demand destruction will need to be the persistent solver on scarcity, an effect requiring substantially higher pricing than current, in our view. In this context, we maintain our view that the copper price will surge into next year (GSe 2025 $15,000/t average), expecting copper to rise to $10,000/t by year-end and then $12,000/t by end of Q1-25’

Another reason why Goldman is doubling down on its bullish copper outlook: gold.

The sharp rally in gold price since the beginning of March has ended the period of consolidation that had been present since late December. Whilst the initial catalyst for the break higher came from a (gold) supportive turn in US data and real rates, the move has been significantly amplified by short term systematic buying, which suggests less sticky upside. In this context, we expect gold to consolidate for now, with our economists near term view on rates and the dollar suggesting limited near-term catalysts for further upside momentum. Yet, a substantive retracement lower will also likely be limited by resilience in physical buying channels. Nonetheless, in the midterm we continue to hold a constructive view on gold underpinned by persistent strength in EM demand as well as eventual Fed easing, which should crucially reactivate the largely for now dormant ETF buying channel. In this context, we increase our average gold price forecast for 2024 from $2,090/toz to $2,180/toz, targeting a move to $2,300/toz by year-end.
