Reinvigorating exhausted T cells in cancer and chronic viral infections cells. However, in chronic viral infection and cancer, the killer cells often lapse into “exhausted” CD8+ T cells that no longer can stem disease

Researchers at University of Alabama at Birmingham identify Gfi1 as a crucial regulator of exhausted CD8+ T cell subsets. Fine-tuning Gfi1 activity may prevent or reverse T cell exhaustion, bolstering immune checkpoint blockade therapy. The study suggests potential for improving cancer treatment and controlling chronic infections.

Brown University neuroscientists help identify a biomarker for Alzheimer’s disease progression

Researchers at Brown University have identified a brain-based biomarker that can predict mild cognitive impairment development into Alzheimer's disease. They used a custom-built tool to analyze electrical activity from neurons and found distinct differences in beta events between patients who developed the disease and those who did not.

UofL research shows combined exposure to alcohol and “forever chemicals” increases liver damage

A study from University of Louisville researchers found that perfluorooctane sulfonate (PFOS) can worsen liver damage when combined with alcohol consumption. The study showed that PFOS exposure can increase fat accumulation and markers of liver damage, disrupt the liver's ability to manage fats, and activate pathways that promote liver...

A comparison of colorful hamlets from the Caribbean challenges ideas about how species arise

A study by 16 researchers, including those from the Smithsonian Tropical Research Institute, found that genetic differences alone cannot explain how 19 species of hamlet fish diverged. Instead, they identified a single gene involved in color patterns and mate choice, but it did not allow them to reconstruct a family tree for the group.

Both flexibility and persistence make some birds successful in human-made environments

Research suggests that great-tailed grackles, a species expanding its range across the US, possess high levels of behavioral flexibility. This trait enables them to adjust their foraging behaviors and exploit human-provided resources. However, sociability and habitat use were not strongly correlated with flexibility.

Turning down the dial on inflammation to protect against lupus nephritis

Researchers at Medical University of South Carolina develop a new approach to preventing lupus nephritis by improving kidney cell function. Exposure to serum from patients with lupus nephritis causes inflammation, but simultaneous exposure to L-sepiapterin reduces inflammation and enhances nitric oxide production.
