Researchers discover a direct pathway for macrophage cleanup

Macrophages are part of the immune system's frontline; they attack and eat invaders to protect surrounding cells. They, along with other cells, maintain intracellular conditions through macroautophagy, using autophagosomes to help digest broken cell components.

Research reveals molecular details of ME/CFS and long COVID

Patients with chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS) have heightened innate immune responses to bacteria, viruses, and fungi. While these responses are essential to fight infection, they can cause damage when unchecked.

Can honey protect your brain? Study reviews its potential against Alzheimer's

This review examined 27 preclinical studies on honey and Alzheimer’s disease, showing honey’s bioactive compounds counter oxidative stress, inflammation, and amyloid buildup. Despite promising lab results, no human trials exist, underscoring the need for clinical research.

Why metformin could protect the brain by rewiring mitochondria

Metformin boosts human oligodendrocyte differentiation and myelination across stem-cell, organoid, and chimera models. The study links these effects to mitochondrial metabolic shifts, supporting its potential as a therapy for multiple sclerosis.

Cancer-related nerve injury triggers inflammation and immunotherapy resistance

Cancer cells can break down the protective covers around nerves, causing nerve injury that triggers chronic inflammation leading to immune exhaustion and eventual resistance to immunotherapy, according to new research from The University of Texas MD Anderson Cancer Center.

$New hypothesis links internal fat biology to heart failure with preserved ejection fraction$

New hypothesis links internal fat biology to heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFpEF) appears to develop as a result of changes in the biology of a person's internal fat tissue, according to the Adipokine Hypothesis, a new way of understanding how fat may impact the heart.

Can oral bacteria make heart disease worse?

The presence of viridans streptococci in coronary plaques indicates a role in atherosclerosis, potentially influencing heart disease outcomes.

Babies fed blueberries show fewer allergy symptoms and boosted immune balance

Daily blueberry powder given to infants during complementary feeding modestly influenced allergic symptom resolution and shaped immune biomarker–microbiota associations. Findings suggest early diet may play a role in immune development, though results are preliminary and exploratory.

How plant compounds could target Alzheimer’s disease from multiple angles

This review highlights how dietary polyphenols modulate Alzheimer’s disease biology through antioxidant, anti-inflammatory, and multi-target mechanisms, supported by in-silico docking analyses. Despite promise, challenges in bioavailability and brain delivery remain key hurdles to clinical translation.

Discovery of mitochondrial microprotein opens path to obesity and aging therapies

Like bees breathing life into gardens, providing pollen and making flowers blossom, little cellular machines called mitochondria breathe life into our bodies, buzzing with energy as they produce the fuel that powers each of our cells.

Alzheimer’s research uncovers a new therapeutic pathway for the memory-robbing malady

The gut contains the largest collection of immune cells in the body. New research at the Buck Institute shows that some of those immune cells travel along the brain/gut axis in a mouse model of Alzheimer's disease (AD) providing a potential new therapeutic pathway for the memory-robbing malady.

Constipation drug found to slow renal function decline in CKD patients

Chronic kidney disease (CKD) is a major health issue worldwide. Many patients end up requiring regular dialysis to avoid kidney failure and stay alive.

Two-stage pimple patch eliminates acne in seven days

Waking up with a pimple is no longer cause for panic, thanks to pimple patches - small, sticker-like bandages that cover and help heal the unwanted zit.

Daily use of low-dose colchicine may slow growth of blood mutations linked to disease

Taking low-dose colchicine daily may slow the progression of a common acquired gene mutation found in the blood of older adults that can lead to certain blood cancers and increased risk of cardiovascular disease, according to a subanalysis of the LoDoCo2 trial published in JACC, the flagship journal of the American College of Cardiology, and simultaneously presented at ESC Congress 2025.

Herpes zoster vaccination linked to lower risk of heart attack and stroke

A new global systematic literature review and meta-analysis has shown that herpes zoster vaccination, used to prevent shingles, is associated with a statistically significant lower risk of heart attack and stroke.

Inflammation marker can help identify heart risk in women without traditional factors

Cardiologists have long known that up to half of all heart attacks and strokes occur among apparently healthy individuals who do not smoke and do not have high blood pressure, high cholesterol, or diabetes, the "standard modifiable risk factors" which doctors often call "SMuRFs."

New project uses advanced PET imaging to investigate long COVID mechanisms

Using total-body PET imaging to get a better understanding of long COVID disease is the goal of a new project at the University of California, Davis, in collaboration with UC San Francisco.
