DPO-1 merits exploration as a T-cell modulator; hypothesis-generating and requires in vivo validation before any clinical consideration.
Does Diphenyl phosphine oxide-1 (DPO-1) inhibit Kv1.3 channel activity and suppress IL-2 secretion in human T cells?
DPO-1, a known Kv1.5 inhibitor for atrial fibrillation, also potently blocks Kv1.3 channels and suppresses IL-2 secretion in human T cells, suggesting potential as an immunomodulatory agent.
