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.

Honey, Olive Oil splash with droplets on white background. Macro camera 4K size. 3d illustration.
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Protein molecules form crystals by arranging themselves in a regular pattern. Their shape is like a transparent gem and attracts many scientists. Protein crystal structures are an important area of research that can provide clues for drug discovery. This image is reminiscent of a protein crystallising in solution.\nThis image was not created by AI.
Amitriptyline is used as an antidepressant and antimigraine drug. It blocks sodium channels on neuronal membrans. Sodium channels generate and propagate action potentials in neurons and muscle. Source: PDB entry 6AGF

Tyrosylprotein sulfotransferase is the enzyme that catalyzes the sulfation reaction of protein tyrosines, a post-translational modification of proteins. 3D surface model, white background.
Lactose-negative biofilm-forming Enterobacter cloacae, resistant to multiple drugs.  Enterobacter cloacae is a member of the normal gut flora. These bacteria are responsable for many hospital-acquired infections for which the mortality rate is generally high.
The amyloid beta peptide (light blue) is a component of the amyloid precursor protein, which is bound to a cell membrane. The gamma secretase enzyme cuts the free form, that aggregates to amyloid plaques. Source: PDB entries 2beg, 1mwp

Pathogen yeasts infections are treated with fluconazole, that blocks the lanosterol 14-alpha demethylase. This enzyme is essential for the biosynthesis of ergosterol, that is essential for the permeability and rigidity of the fungal plasma membrane. The magnification shows the active site with fluconazole interacting with a heme group. Source PDB entry 5esf.
