Psilocybin protects sensory nerves from chemotherapy damage in preclinical study

In mouse models, prophylactic psilocybin prevented or reduced multiple features of chemotherapy-induced peripheral neuropathy, with cycle-matched dosing sustaining protection during repeated cisplatin exposure without measurably affecting tumor growth. Experiments in human-derived sensory neurons and ex vivo peripheral nerves linked the effect to 5-HT2A-dependent preservation of mitochondrial trafficking and local axonal energy supply, while a nonhallucinogenic 5-HT2A agonist reproduced protection against mechanical hypersensitivity.

New method based on human blood simplifies mRNA drug development

mRNA-based drugs are emerging as the drug of the future for a wide range of diseases, but they are difficult and time-consuming to develop.

Mitochondrial transplantation helps repair donor organs during machine perfusion

Transplant medicine still depends on a limited supply of donor organs, while many retrieved grafts are discarded because ischemia, cold storage, and reperfusion can rapidly damage their cells.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

New review urges proteostatic fitness standards for stem cell therapies

Stem cell therapies have expanded rapidly, with more than 115 clinical trials involving over 1,200 patients approved by late 2024. The U.S. Food and Drug Administration (FDA) recently approved Ryoncil (remestemcel‑L) for children with steroid‑refractory acute graft‑versus‑host disease, signaling a major shift toward routine clinical use.

Voltammetry and machine learning for real-time neurotransmitter detection

Anne Andrews (UCLA) explains how voltammetry and machine learning can track multiple neurotransmitters in real time, even with overlapping signals.

Evidence shows artificial sweeteners cannot be judged as a single group

This narrative review found that non-nutritive artificial sweeteners have compound-specific and context-dependent associations with gut microbiota, metabolism, and health-related outcomes. Evidence does not support treating all sweeteners as uniformly harmful or safe, with human findings often limited or inconsistent.

Melatonin dampens fetal membrane inflammation linked to preterm birth

Melatonin reduced infection-related inflammation in human fetal membranes in an ex vivo model. The study suggests that this effect works partly through melatonin receptors and by suppressing the TLR4/MyD88/NF-κB pathway.

New vaccines successfully boost frontline immune cells against HIV

T-cells are the immune system's frontline defenders with a crucial role in controlling HIV. In a milestone clinical trial published in the Journal of Clinical Investigation, researchers with the UNC Institute for Global Health and Infectious Diseases (IGHID) at the UNC School of Medicine have demonstrated that new vaccines can significantly boost T cells targeting the most vulnerable, conserved regions of HIV-areas considered key to effective immune control.

Western diet weakens the gut’s nervous system through iron-dependent damage

A JCI study found that exposure to a Western diet in mice and to palmitic acid in murine and ex vivo human enteric nervous system models triggered ferroptosis, characterized by iron loading, lipid peroxidation, mitochondrial stress, and enteric neuronal loss. Boosting Nrf2 signaling protected enteric neurons and prevented Western diet-induced delayed colonic transit in mice, pointing to a potential pathway linking dietary fat exposure to gut motility dysfunction.

Aged immune cells may drive memory decline by releasing a brain-aging protein

A preclinical mouse study in Immunity suggests that aged circulating CD8+ T cells can disrupt hippocampal function and impair learning and memory. The findings point to granzyme K, a secreted factor linked to age-associated CD8+ T cells, as a potential target for restoring aspects of cognition in aging.

Engineered regulatory T cells offer a path toward immunosuppression-free transplants

Organ transplantation remains the cornerstone treatment for end-stage organ failure. While conventional broad-spectrum immunosuppression effectively controls acute rejection, it fails to address chronic rejection and carries long-term side effects including infection, malignancy, and metabolic disorders.

Lab-grown skin organoids provide new insights into blood vessel pathology

New research has shown that single blood vessel cells that appear in the earliest stages of lab-grown skin organoids have the ability to form complex microvascular networks that grow and mature over time.
