The interaction of antigen with immunologically competent cells may lead either to the induction of an immune response or to a state of antigen specific unresponsiveness complete orpartial, which is often called immunological 'tolerance'. This is believed to be a major mechanism of discrimination between self and non-self(1-3). In this review Marc Feldmann and his colleagues discuss new insights into T-cell tolerance in vivo and in vitro, and discuss their significance for our understanding of mechanisms of immune activation and regulation.

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...
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
