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.

Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is  not available for use anywhere else. I created it on Blender 3.0.1,  and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.

Molecular Model of Cyclosporine, an immunosuppressant drug widely used in organ transplantation to prevent rejection.
Cholera toxin, molecular model. Cholera toxin (choleragen) is a protein complex secreted by the bacterium Vibrio cholerae, that causes the disease cholera. It is made up of a wedge-shaped A subunit (right part of illustration) and five B subunits (left part of illustration) that form a ring which binds to the intestinal lining. In its most severe forms, cholera is one of the most rapidly fatal illnesses known.
Evolution of nanotechnology and self-proliferation of therapeutic agents
A new antibiotic (zosurabalpin, red) traps lipopolysaccharide (orange) in the intermembrane transporter of the Gram-negative bacterium Acinetobacter baylyi
Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.
Integrins are the principal receptors used by animal cells to bind to the extracellular matrix. They are heterodimers and function as transmembrane linkers between the extracellular matrix and the actin cytoskeleton. A cell can regulate the adhesive activity of its integrins from within.
