Vitamin A derivative suppresses immune response and cancer vaccine efficacy

Scientists at the Princeton University Branch of the Ludwig Institute for Cancer Research have identified novel mechanisms by which a metabolic derivative of vitamin A-all-trans retinoic acid-compromises both the body's normal anti-cancer immune response and, in a different context, the efficacy of a promising type of cancer vaccine.

Inhalable nanotherapy can activate the immune system against checkpoint-resistant melanoma

Immune checkpoint molecules play a crucial role in keeping the immune system in balance and preventing an attack on the body's own cells.

Single-cell RNA-seq reveals FBLN7's role in adipose tissue fibrosis

Fibrosis, resulting from excess extracellular matrix (ECM) deposition, is a feature of adipose tissue (AT) dysfunction and obesity-related insulin resistance.

Gut microbe metabolite TMA improves blood sugar by shutting down a key inflammatory switch

Researchers identified trimethylamine (TMA) as a gut microbe–derived metabolite that directly inhibits IRAK4 to reduce metabolic inflammation and improve glycaemic control in high-fat-diet-fed mice. Choline-driven increases in TMA production replicated these benefits, revealing a host–microbe signaling axis with therapeutic potential for obesity-associated insulin resistance.

Study reveals ATM kinase as the key driver of replicative senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

Epigenetic drift explains why the aging intestine becomes more vulnerable to cancer

Researchers from the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) in Jena, Germany, the Molecular Biotechnology Centre (MBC) in Turin and the University of Turin, Italy, have discovered a fundamental mechanism of aging in the gut.
