A ball-and-stick plus ribbons molecular model of the hormone Orexin, also known as Hypocretin.  Orexin is involved in the regulation of the sleep/wake cycle and it stimulates apetite, wakefulness and energy expenditure. It has been linked with Alzheimer's disease.  Isolated on white.
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-.
Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several fatal and transmissible neurodegenerative diseases in humans and many other animals.
