Plasma cells are white blood cells. They produce and segregate antibodies.
Macrophag engulfing bacteria (cocci), 3D rendering. Macrophages engulf and digest cellular debris and pathogens. - Illustration
Dendritic cell. Dendritic cells are antigen-presenting cells of the immune system. They process antigen material and present it on the cell surface to the T cells of the immune system. 3D Rendering. Illustration
T-cell receptor in complex with the MHC class II-peptide complex. The antigen (light green) is a peptide from a tumor cell, bacteria or virus. Different stages of the interaction. 3D-Rendering. Illustration
Macrophages approaching bacteria (bacilli), 3D rendering. Illustration
Plasma cells (B-cells) segregate antibodies to mark to mark an subsequently destroy viruses (influenza viruses).

Food for immune system
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.
Makrophage, type of white blood cell, of the immune system, that engulfs and digests cellular debris, foreign substances, microbes, cancer cells
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
T-lymphocytes and dendritic cells, 3D-rendering; Dendritic cells are antigen-presenting cells of the immune system. They process antigen material and present it on the cell surface to the T-cells. 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
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
Interactions of MHC-II with the T-cell receptor and CD4 and B7-1 with CD-28 activates T-cells while the interactions of P7-1 with CTLA-4 and PD-L1 with PD-1 deactivates T-cells.
T-cell receptor in complex with the MHC class II-peptide complex. The antigen (light green) is a peptide from a tumor cell, bacteria or virus. Complex embedded in the membranes. 3D-Rendering. Illustration

Plasma cells segregating antibodies. Illustration
Cancer cells express PD-L1 (orange) proteins on their surface to trick the immune system. The interaction of PD-L1 with PD-1 of T-cells leads to a down-regulation of T-cells. The antibody (yellow) blocks this interaction.
