Dendritic Cell Presenting An Antigen To T-lymphocytes Royalty-Free Illustration

3d computer illustration of an antigen presenting cell. The antigen is a peptide from a tumor cell, bacteria or virus. Dendritic cells present antigens to lymphocytes through their membran bound MHC-molecules . After binding to the MHC-antigen complex, the T-cell receptor sends a a signal cascade into the T-lymphocyte cell, that activates an immune response.
