Activation of certain memory B cells may be driving systemic lupus erythematosus incidence in individuals who had ...

Immune cells called B cells make antibodies that fight off invading bacteria, viruses and other foreign substances. During ...

University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center scientists have discovered a novel subset of cancer-fighting immune cells that reside outside of their normal neighborhood – ...

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. – ...

At the surface, the immune response to a flu virus is simple. Some cells recognize the pathogen and send a signal to the immune system, and immune cells produce a potentially lifesaving antibody ...

Background Withdrawal of prolonged nucleos(t)ide analogue (NA) treatment results in hepatitis B surface antigen (HBsAg) loss in some subjects with chronic hepatitis B (CHB), potentially revealing ...

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, ...

Getting measles doesn’t confer benefits on the immune system — in fact, it’s just the opposite. Even a mild case of measles destroys the memory cells that confer resistance on bugs the patient has ...

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 ...
