Lymphocyte Cell Concept
T-lymphocyt, virus
The Blood System
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
Lymphocyte, closeup view of T-cell or B-cell
T-cell receptor bound to a cell membrane
Macrophage binding with t cell
Macrophage binding with t cell
human lymphocyte T cell
human T helper cell
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.
Macrophage binding with t cell
Activation of the immune response to an antigene (green) through the complex between a T-cell receptor (dark blue), an MHC II-antigen (violet) and a CD4 protein (light blue). 3d rendering. Illustration

Mechanisms of immune defense against viruses, 3D 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.
Human Antigene and bacteria
Human Cytotoxic T cell
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
Human Cytotoxic T cell
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

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
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.
