Three Monoclonal Antibodies to Antigen Presenting Cells in the Rat with Differential Influence on Cellular Interactions
Part of the
Advances in Experimental Medicine and Biology
book series (AEMB, volume 329)
A physical interaction between antigen presenting cells (APC) and T cells is essential for evoking an immune response1. It has been proposed that T cells first bind to APC by an antigen-independent mechanism. Antigen specific lymphocytes are then selected and activated within the APC-T cell cluster resulting in T cell proliferation2. In the first stage several accessory molecules, like LFA-1, ICAM-1, CD2, and LFA-3, are involved in the antigen-independent interaction1,2,3. Thereafter the antigen-dependent interaction, mediated by the T cell receptor (TCR), CD3, CD4, and the MHC Class II molecule, becomes more important and induces cytokine production triggering T cell proliferation1,3,4,5. In the third stage, which can occur in the absence of APC, IL-2 alone mediates proliferation of the responsive T cells.
