Effect of oxidative stress on TRPM2 and TRPC3 channels in B lymphoblast cells in bipolar disorder.

Objectives: Recent findings implicate the calcium-permeable nonselective ion channels transient receptor potential (TRP) melastatin subtype 2 (TRPM2) and canonical subtype 3 (TRPC3) in the pathogenesis of bipolar disorder (BD). These channels are involved in calcium and oxidative stress signaling, both of which are disrupted in BD. Thus, we sought to determine if these channels are differentially affected by oxidative stress in cell lines of BD patient origin.
