Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found ...

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 ...

Georgetown University's Lombardi Comprehensive Cancer Center researchers have identified a new way to reprogram T cells, which are infection and tumor-fighting white blood cells, so that they have a ...

A multi-institutional study has mapped the genetic circuitry that determines whether CD8 killer T cells become durable immune defenders or lapse into exhaustion, and has shown that disabling two ...

Researchers have discovered that some CAR-T cells engineered to fight cancer and other conditions carry the memory of past encounters with bacteria, viruses and other antigens within them, a finding ...

The Golgi apparatus modifies, sorts and packages proteins to be sent to their final destinations, whether that's within or outside of the cell. It's a core function, but little studied in the setting ...

For decades, dogma dictated that the immune system consisted of two separate branches. Cells of the innate system respond rapidly to molecular patterns shared by a broad array of pathogens. Meanwhile, ...
