Turning immune cells into tumor allies: A cancer cell protein can reprogram frontline defenders
Cancer cells can disarm the immune system not just by hiding from it, but by actively reprogramming nearby immune cells into a suppressed state. This previously unrecognized molecular interaction, discovered by scientists ...

Unleashing natural killer cells against cancer
Scientists have developed a strategy to boost the cancer-fighting power of natural killer (NK) cells, part of the immune system's first line of defense. NK cells can detect and destroy cancer cells, but tumors often create ...

How a chemical reaction triggers brain inflammation in Alzheimer's disease
The brain has its own immune system, which detects threats and mounts a defense. A growing body of evidence has shown that in Alzheimer's disease, those immune cells are chronically overactivated, causing inflammation that ...

B cells that fight infections may also boost muscle performance during exercise
B cells are white blood cells that form a core part of the body's adaptive immune system, enabling it to recognize specific infections, remember them, and mount a targeted response by producing antibodies. A recent study ...
HIV's earliest immune battle leaves blood traces that forecast powerful antibodies years later
Some people living with HIV develop antibodies capable of neutralizing many different strains of the virus. New research links this to immune responses that occur early in infection. The findings, published in PLOS Pathogens, ...

Inside tumors, immune cells hide a split personality—and one side could quietly decide cancer's fate
Macrophages, key regulators of tissue health and immune defense, are among the most abundant immune cells in solid tumors. Their role in cancer has been difficult to define because even closely related macrophage populations ...
