Survival of Transplanted Allogeneic Beta Cells with No Immunosuppression | NEJM The need to suppress a patient’s immune system after the transplantation of allogeneic cells is associated with wide-ranging side effects. We report the outcomes of transplantation of genetically m...

Important first-in-human report today for donor pancreatic islet beta-cell transplant to an individual w/Type 1 diabetes. With genome editing, there was no immune response induced or need for immunosuppression. Major implications for transplantation in general @nejm.org

Diet outperforms microbial transplant to drive microbiome recovery in mice - Nature Experiments in mouse models show that proper recovery of the intestinal microbiota following depletion, with or without faecal microbiota transplant therapy, is dependent on syntrophic interactions th...

To restore the gut microbiome after antibiotics, the right diet (rich in carbohydrates, low in fat) was a better approach than fecal microbial transplants (in the experimental model)

Lorundrostat - an aldosterone synthase inhibitor.
Lorundrostat was associated with greater reductions in 24-hr average BP than placebo in pts with uncontrolled & treatment-resistant hypertension.
K level >6.0 occurred in 5 pts (5%) in the stable-dose group.

The nitroplast: A nitrogen-fixing organelle A bacterial endosymbiont of marine algae evolved to an organelle

Move over mitochondria, a new organelle called the nitroplast is here.

In a Science study from earlier this year, researchers report that a nitrogen-fixing organelle has been identified in a marine alga. Learn more in this #SciencePerspective:

The Anatomical Quirk That Saved Dr. No A wild tale of how scientists unraveled embryology's most fascinating mystery.

U.S. okays organ transplants between people with HIV, expanding donor pool The landmark move is expected to shorten wait times for organs for all patients and reduce hurdles to life-saving care for those with HIV.

People with HIV will be able to receive kidney or liver transplants from donors who also have HIV, federal health officials announced Tuesday.

The landmark move, which takes effect Wednesday, is expected to shorten wait times for organs for all patients.

"Drink more water!" It's the easiest health advice around. Tired? Headache? Trying to be like Tom Brady? Just drink more water. But as a nephrologist, I get asked all the time: How much is the right amount? And the truth is... we don't really know. 🧵

Kaplan Meier curve showing the cumulative incidence of type 2 diabetes in people given tirzepatide vs placebo

This month, a phase 3 trial of tirzepatide (a GLP-1 drug) found that it reduced the chances of developing type 2 diabetes by around 90% (!), among people with obesity and pre-diabetes.

That's a reduction if I ever saw one.

Down goes daprodustat.

The HIF-PHI drugs for CKD anemia will go down as the drug class with the greatest hype that utterly failed in delivering anything of note for patients. Just an epic decades long drama for nothing.

I sometimes forget how flexible proteins are. It becomes really apparent when you use NMR states for an animation. That poor cofactor is getting pushed around a lot 😅

Hepatocellular senescence induces multi-organ senescence and dysfunction via TGFβ - Nature Cell Biology Kiourtis et al. show that liver senescence triggers senescence and dysfunction in other organs through TGFβ secretion from the liver.

Is your liver engaging in a bad game of telephone? 📞

🆕 research shows that liver senescence (biological aging) spreads to other organs. Liver signals ➡️ multi-organ dysfunction. 🤨 How? TGF-B (a hepato-senescent factor) causes systemic spread of senescence.
