One of my major research interests is mimicking receptor-ligand interactions using peptides.
Whilst at Affymax Research Institute I discovered small peptides that mimic the actions of various cytokines/growth factors. Of these, the EPO mimetics are the furthest along in the clinic, being the first potential product of Affymax Inc.
Please feel free to contact me with questions you might have related to cytokine mimetics.
