The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor has a strong effect on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

Interleukin-2 (IL-2) is a protein crucial for regulating immune responses, stimulating the growth and differentiation of various immune cells. Its receptor, found on immune cells, comes in three forms: high-affinity trimeric, intermediate-affinity dimeric, and low-affinity monomeric. Binding of IL-2 to its receptor activates signaling pathways, influencing cellular proliferation and immune function. Dysregulation of IL-2 signaling can contribute to autoimmune diseases and cancer, making it an important target for therapeutic intervention.

Illustration of fentanyl molecules (red) interacting with the mu-opioid receptor on a cell membrane. Opioid receptors are found on nerve cells. When pain is detected by the body, endorphins are released and attach to the receptors, starting a reaction that modulates pain perception. Opioid drugs such as fentanyl mimic endorphins.

Dopamine is a chemical messenger and neurotransmitter produced in the brain that affects many bodily functions. It's an organic chemical that's part of the catecholamine and phenethylamine families. Dopamine is responsible for many effects, including mood, movement, memory, motivation, attention.

Antibody binding to human cell receptors is a crucial aspect of the immune response and plays a fundamental role in various physiological processes, including immune defense, signaling, and regulation of cellular functions. Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of foreign substances, such as pathogens or abnormal cells.

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. Dendritic cells present antigens to lymphocytes through their membran bound MHC-molecules (violet). CD4 molecules (light blue) bind to other portions of the MHC, strengthening the interaction. After binding to the MHC-antigen complex, The T-cell receptor (blue) sends a signal cascade through an attached G-protein into the T-lymphocyte cell, that activates an immune response.
