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 – ...

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 ...

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

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 ...

Conjugate vaccines are composed of bacterial polysaccharide antigens covalently linked to protein carriers, enabling T cell-dependent immune responses that induce high-affinity antibodies and ...

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. – ...
