Immunopharmacology Comments
The role of PIN1 in modulating cytokine expression by activated T cells and eosinophils suggests that targeting this enzyme may offer potential for the development of therapeutics for immunologic diseases such as asthma and organ rejection [3,6-7,11].
General Comments
PIN1 isomerises phosphorylated serine/threonine-proline bonds, a protein modification that is involved in the regulation of a range of cellular processes, including cell cycle progression [5] and protein folding and processing [1]. It has been proposed as a drug target for cancer [10] and diseases that are associated with defective amyloid protein processing such Alzheimer's disease [2,8]. Evidence also suggests that PIN1 plays a role in the immune system, in pathways that are distinct from those regulated by other immune system PPIases (peptidylprolyl isomerase A/cyclophilin A and FKBP prolyl isomerase 1A) [3].
