Lysosomal activity in worms linked to transgenerational extension of lifespan

In the Wang Lab, it's not unusual for worms to live for a long time. HHMI Janelia Research Campus Senior Group Leader Meng Wang and her team study longevity. They've shown that by overexpressing an enzyme in the lysosomes of the roundworm C. elegans, they can extend the worm's life by up to 60 percent.

How food choices and cooking methods drive brain inflammation and disease

Researchers reviewing evidence in NeuroSci show how dietary AGEs and their interaction with RAGE drive oxidative stress, inflammation, and neurodegeneration. They highlight how cooking methods and diet choices could lower AGE burden and protect brain health, while calling for rigorous clinical trials.

Lysosomal acidity fine-tunes reactive species production in macrophages

Macrophages rely on lysosomes to balance microbial killing with self-protection, generating reactive oxygen and nitrogen species during phagocytosis.

Genetic variant disrupts brain’s cleanup crew increasing Alzheimer’s risk

A Nature study published today and led by researchers at the University of South Florida's USF Health Byrd Alzheimer's Institute pinpoints how a genetic variant disrupts microglia - the brain's "cleanup crew" - increasing the risk of Alzheimer's disease.

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.

Cellular purging process may help injured cells revert to stem cell-like state more rapidly

Now, a new study in mice led by researchers at Washington University School of Medicine in St. Louis and the Baylor College of Medicine reveals a previously unknown cellular purging process that may help injured cells revert to a stem cell-like state more rapidly.

Research shows how lysosomes respond to stress

New research, published today in the journal Science, shows how lysosomes - organelles that act like cells' waste disposal system - respond to stress by becoming abnormally bloated, a process called lysosomal vacuolation that is associated with numerous diseases.

New pH-responsive nanomaterials enhance precision drug delivery to tumors

Cancer remains one of the leading causes of death worldwide, and despite advancements in diagnosis and treatment, it continues to impose a significant health burden globally.

Targeted microglia replacement shows promise against fatal neurodegenerative conditions

Tay-Sachs and Sandhoff diseases, genetic disorders affecting the brain, have no effective treatment and are typically fatal within the first years of life.

Human eggs use a minimalist strategy to stay healthy for decades

Human eggs are some of the most patient cells in the body, lying dormant for decades until needed. A study published today in The EMBO Journal shows that the cells deliberately slow the activity of their internal waste disposal systems as they mature, most likely an evolutionary design which keeps metabolism low and damage at bay.

Artificial intelligence tracks aging and damaged cells through high resolution imaging

A combination of high-resolution imaging and machine learning, also known as artificial intelligence (AI), can track cells damaged from injury, aging, or disease, and that no longer grow and reproduce normally, a new study shows.

Researchers turn a deadly fungus into potent cancer-fighting compound

Penn-led researchers have turned a deadly fungus into a potent cancer-fighting compound. After isolating a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to deaths in the excavations of ancient tombs, the researchers modified the chemicals and tested them against leukemia cells.

Sucralose disrupts male fertility by damaging sperm and altering hormones in animal study

Researchers found that chronic sucralose exposure in male rats disrupted reproductive hormones, damaged sperm, and impaired testicular function through oxidative stress and autophagy dysregulation. These findings raise concerns about the reproductive risks of high sucralose intake and its persistent presence in the environment.
