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.
Macrophage engulfing pathogen. Illustration. White blood cell. Immune system.
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

Immunologically active proteins on a T-cell. TCR (blue), CD-4 (light blue), CD-28 (dark blue), PD-1 (magenta), CTLA-4 (violet), Ca-channel (dark violet). The T-cell receptor, CD-4 and CD-28 activate T-cells, while PD-1 and CTLA-4 inhibit the activat
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.
Abnormal malignant cells specimen pleural fluid.
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

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
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
Phagocytosis . Step by step process of macrophage is swallowing and killing microbes . Isolated white background . Medical immunity concept . 3D rendering .
Dying epithelial cells
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

Dendritic cell. 3D-rendering. Dendritic cells are antigen-presenting cells of the immune system. Illustration
T lymphocytes attacking cancer cell; 3D-rendering Natural killer cells are a type of lymphocytes which destroy cancer cells and other altered cells releasing cytotoxic granules. 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
Macrophage is swallowing any bacteria ( Phagocytosis ). White blood cells with transparency membrane and many bacteria in vacuoles . Isolated white background . 3D render .
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.
