Insulin receptor inactivated (left) and activated (right) after insulin binding
The insulin receptor (blue) is a transmembrane protein, that is activated by insulin (orange). Insulin binding induces structural changes within the receptor that finally leads to the activation of the glucose transporter protein.

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
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
Structure of human interleukin-21, 3D cartoon model isolated with the colored elements of the secondary structure, white background
3d computer illustration of an activated Ras protein. Ras proteins are involved in transmitting signals within cells turning on genes involved in cell growth, differentiation and survival. Mutations in ras genes can lead to permanently activated prot

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.
Activation of a Ras protein Inactive Ras protein (left) is activated by a GEF protein opening the binding site allowing GDP to exit. Then GTP can bind to RAS turning it into the active form. 3d render. Illustration
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

Calmodulin, a crucial messenger protein. Calmodulin has 4 Ca2+ binding sites.
3d computer illustration of an activated Ras protein with GTP bound. Ras proteins are involved in transmitting signals within cells turning on genes involved in cell growth, differentiation and survival. Mutations in ras genes can lead to permanentl
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.
Calmodulin, a crucial messenger protein
3d computer illustration of the activation process of a Ras protein. Inactive Ras protein (left) is activated by a GEF protein opening the binding site and allowing GDP to exit. Afterwards GTP can bind to RAS turning it into the active form (right).
Structure of human interleukin-11, 3D cartoon model isolated, white background
Rhodopsin is a light sensitive G-protein coupled receptor with retinal as cofactor. that stimulates the G-protein transducin, resulting in the liberation of its subunit. This GTP-bound subunit in turn activates cGMP phosphodiesterase.
Activation of the GABA B receptor by baclofen. GABA B receptors are G protein-coupled receptors. Binding of an agonist (baclofen, red) leads to a G-protein coupled C-AMP signaling pathway. Source: PDB entries 7eb2, 6r3q,.
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
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
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.
