When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which ...

Investigators led by Navdeep Chandel, Ph.D., the David W. Cugell, MD, Professor of Medicine in the Division of Pulmonary and Critical Care, have discovered how the metabolism of mitochondria supports ...

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 ...

The concept of trained immunity has redefined innate immune responses as adaptable, durable, and context dependent. Natural killer (NK) cells, traditionally ...

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, ...

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 ...

T lymphocytes differentiate from naïve precursors upon antigen encounter into distinct effector and memory subsets. Following priming by antigen-presenting cells in lymphoid tissues, naïve CD4+ and ...

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 ...

Research from Radboud University Medical Center reveals that T cells from the adaptive immune system can manipulate the memory of innate immune cells. Previously, it was believed that the memory of ...

T-bet expression is required for persistence of memory B cells that have rapid differentiation potential to become antibody-producing plasma cells in response to a second infection BIRMINGHAM, Ala. – ...
