Lupus Was Considered Incurable. New Breakthroughs Fuel Hope

Lupus, doctors like to say, affects no two patients the same. The disease causes the immune system to go rogue in a way that can strike virtually any organ in the body, but when and where is maddeningly elusive. One patient might have lesions on the face, likened to wolf bites by the 13th-century physician who gave lupus its name. Another patient might have kidney failure. Another, fluid around the lungs. What doctors can say to every patient, though, is that they will have lupus for the rest of their life. The origins of autoimmune diseases like it are often mysterious, and an immune system that sees the body it inhabits as an enemy will never completely relax. Lupus cannot be cured. No autoimmune disease can be cured.

Two years ago, however, a study came out of Germany that rocked all of these assumptions. Five patients with uncontrolled lupus went into complete remission after undergoing a repurposed cancer treatment called CAR-T-cell therapy, which largely wiped out their rogue immune cells. The first treated patient has had no symptoms for almost four years now. ‘We never dared to think about the cure for our disease,’ says Anca Askanase, a rheumatologist at Columbia University’s medical center who specializes in lupus. But these stunning results—remission in every patient—have fueled a new wave of optimism. More than 40 people with lupus worldwide have now undergone CAR-T-cell therapy, and most have gone into drug-free remission. It is too early to declare any of these patients cured for life, but that now seems within the realm of possibility.

Pancreatic Cancer Surge May Be Less Worrisome than It Seemed

One of the first warnings came in a paper published in 2021. There was an unexpected rise in pancreatic cancer among young people in the United States from 2000 to 2018. The illness can be untreatable by the time it is discovered, a death sentence.

With publication of that report, by Dr. Srinivas Gaddam, a gastroenterologist at Cedars-Sinai Medical Center, researchers began searching for reasons. Could the increase be caused by obesity? Ultraprocessed foods? Was it toxins in the environment?

Alternatively, a new study published on Monday in The Annals of Internal Medicine suggests, the whole alarm could be misguided.

What’s the secret to living to 100? Centenarian stem cells could offer clues

From the article:

Scientists in Boston, Massachusetts have made reprogrammed stem cells from the blood of centenarians.


Centenarians offer an opportunity to study longevity. People who’ve lived to 100 have an amazing ability to bounce back from insult and injury, says George Murphy, a stem-cell biologist at the Boston University Chobanian & Avedisian School of Medicine. One centenarian he knows recovered from the 1912 Spanish flu and COVID-19, twice. One theory that explains centenarians’ robust age is that they possess a genetic makeup that protects them from diseases.

But testing that idea is a challenge. People of that age are rare, which makes blood and skin samples from them a precious resource for research. That gave Murphy and his colleagues the idea to create a bank of centenarian cells that could be shared among scientists.

Scientists identify a form of vitamin B6 as a means of engaging tumor-reactive immune cells

Effective immunity hinges on the ability to sense infection and cellular transformation. In humans, there is a specialized molecule on the surface of cells termed MR1 allows sensing of certain small molecule metabolites derived from cellular and microbial sources; however, the breadth of metabolite sensing is unclear.

Published in PNAS, researchers at the Monash University Biomedicine Discovery Institute have identified a form of vitamin B6 bound to MR1 as a means of engaging tumor-reactive . The work involved an international collaborative team co-led by researchers from the University of Melbourne.

According to Dr. Illing, “Our findings suggest that vitamin B6 molecules displayed by MR1 represent a means for the to detect altered cellular metabolism/metabolite levels, that may distinguish ,” she said.

A Common Blood Pressure Drug Extends Lifespan And Slows Aging in Animals

The hypertension drug rilmenidine has been shown to slow down aging in worms, an effect that in humans could hypothetically help us live longer and keep us healthier in our latter years.

Previous research has shown rilmenidine mimics the effects of caloric restriction on a cellular level. Reducing available energy while maintaining nutrition within the body has been shown to extend lifespans in several animal models.

Whether this translates to human biology, or is a potential risk to our health, is a topic of ongoing debate. Finding ways to achieve the same benefits without the costs of extreme calorie cutting could lead to new ways to improve health in old age.

The Role of Cells in Encoding and Storing Information: A Narrative Review of Cellular Memory

Memory, a fundamental aspect of human cognition and consciousness, is multifaceted and extends beyond traditional conceptualizations of mental recall. This review article explores memory through various lenses, including brain-based, body-based, and cellular mechanisms. At its core, memory involves the encoding, storage, and retrieval of information. Advances in neuroscience reveal that synaptic changes and molecular modifications, particularly in the hippocampus, are crucial for memory consolidation. Additionally, body memory, or somatic memory, highlights how sensory experiences and traumatic events are stored and influence behavior, underscoring the role of implicit memory. Multiple studies have demonstrated that memories can be encoded and stored in cells. Evidence suggests that these memories can then be transferred between individuals through organ transplantation.

The Only Known Natural Nuclear Reactor On Earth Is 2 Billion Years Old

Long before humans began creating nuclear reactors to fulfill our ridiculous energy needs, back when the Earth was dominated by microbes, in fact, nature beat us to it and built the first nuclear reactor on Earth.

In May 1972, a physicist at a nuclear processing plant in Pierrelatte, France, was conducting analysis on uranium samples when he noticed something pretty strange. In usual uranium ore deposits, three different isotopes are found; uranium 238, uranium 234, and uranium 235. Of these, uranium 238 is the most abundant, while uranium 234 is the rarest. Isotope 235 makes up around 0.72 percent of uranium deposits, and is the most coveted, as if you can enrich it past 3 percent it can be used to create a sustained nuclear reaction.

In the samples from the Oklo deposits in Gabon, Africa, isotope 235 was found to make up 0.717 percent of the total. That might not sound like much of a difference, but it’s pretty weird.
