We owe a lot to tissue resident memory T cells (T RM). These specialized immune cells are among the body's first responders to disease. Rather than coursing through the bloodstream-as many T cells ...

A new metabolic mechanism describes how tumors disable “gatekeeper” cells to prevent immune response to cancer.

Our brain’s memory center bears a sleek design. A peek into living tissue from human hippocampi, a brain region crucial for memory and learning, revealed relatively few cell-to-cell connections for ...

However, details of the intervening steps, as researchers have learned in the past 65 years, are quite complex — certain cells carry the flu antigen to the immune system, specific immune cells respond ...

AS we age, brain cells face increasing challenges from inflammation, oxidative stress, reduced blood flow, and the buildup of ...
