Abstract:
The immune system employs complex tolerance mechanisms in order to avoid harmful autoimmunity, yet autoantibodies are frequently observed in cancer. In a paper in Cell, Mazor et al. report that autoantibodies produced by tumor-infiltrating B cells in human ovarian cancer frequently recognize the self-protein matrix metalloproteinase 14 (MMP14) through two distinct mechanisms of tolerance disruption.

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Cytotoxic T Cells-mediated Immune Response
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
