TNF-alfa (blue) is the most potent proinflammatory cytokine and is crucial in the pathogenesis of PsA. TNF-  inhibitors considerably relieve symptons in patients. A therapeutic antibody (adalimumab) blocks the receptor binding site of  TNF-.
Molecular model of amylose, one of the two sugar components in starch
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
A molecular model of the flavonoid Quercetin.  An antioxidant and anti-inflamatory, it is used as a nutritional suplement.  It is commonly found in many fruits and vegetables and is a significant chemical component of tea.  Isolated on white.

Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Vegan burger isolated on a woden table
After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
DNA composed of two chains that form a double helix. DNA is a molecule inside cells contains genetic information responsible for the development and function of an organism.
