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-.
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.
