Scientists in Brazil are refining the design of CAR-engineered immune cells to make them more precise and powerful against cancer.

Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which ...

Chinese researchers have developed a novel method to efficiently engineer natural killer (NK) cells for cancer immunotherapy. NK cells are central to early antiviral and anticancer defense—among other ...

Natural Killer (NK) cells are vital immune defenders that target and destroy cancer cells. However, in aging and cancer patients, NK cells often become "senescent"—losing their effectiveness due to ...

Researchers have uncovered a unique ability of a special subtype of natural killer cells in the immune system, called adaptive NK cells, to remember ovarian tumors and effectively attack them. The ...

Cell-based immunotherapies have transformed cancer treatment, yet their widespread use remains constrained by safety risks, manufacturing complexity, and limited effectiveness against solid tumors.

Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both ...

These findings suggest that KIR2DS2-positive (KIR2DS2+) natural killer (NK) cells could be an attractive therapeutic target for in vivo strategies, although enhanced effector function is lost during ...

Natural killer (NK) cells are the bodyguards of our immune system. As a first line of defense, they destroy invading pathogens, foreign bodies, and infected cells in early stages, thereby preventing ...

In addition to strengthening the muscles, lungs, and heart, regular physical exercise also strengthens the immune system. This finding comes from a study of older adults with a history of endurance ...
