Dendritic cells present antigens (green) to lymphocytes through their membran bound MHC-molecules (violet). CD4 molecules (light blue) bind to other portions of the MHC, strengthening the interaction.
Cytotoxic T-lymphocytes attack migrating cancer cells. Illustration
Virus, Immune Mechanism
The T-cell receptor activates the immune response to antigens in T-lymphocytes. T-cell receptors (dark blue), CD4 molecules (light blue), glycolipids (orange). 3d rendering. Illustration
3d computer illustration of a dendritic cell. They areantigen-presenting cells of the immune system. Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. They are messengers betwe

Plasma cells (B-cells) segregate antibodies to mark to mark an subsequently destroy viruses (influenza viruses).
Interaction of MHC-II (red) with the T-cell receptor (blue) and CD4 (light blue) and B7-1 (orange) with CD-28 (dark blue) activates T-cells while the interaction of P7-1 with CTLA-4 (violett) and PD-L1 (yellow) with PD-1 deactivates T-cells
Plasma cells are white blood cells. They produce and segregate antibodies.
Antibodies binding to influenza virus. Illustration
PD-1 (red) extends from the surface of a T-cell and interacts with the ligand protein PD-L1 (yellow) from a antigen presenting cell. Although the T-cell has been activated through the interaction of a T-cell receptor (blue) and a MHC protein (viole
