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.
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.
The sense of smell detects airborne molecules via olfactory receptors in the nasal cavity, sending signals to the brain for perception

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).
Cyclic adenosine monophosphat (cAMP, red) is a second messenger used for signal transduction through the activation of various protein kinases (blue). The one in the foreground is protein kinase A. Source: PDB entry 3tnp.
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
