Lymphocytes are white blood cells or leucocytes in the human imm
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 targeting SARS-CoV-2 viruses. T cells play a key role in the development of long-term immunity. to coronavirus
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.

human lymphocyte T cell
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.
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
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
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
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.
