Biological Activity for OB-1
OB-1 is a stomatin-like protein-3 (STOML3) oligomerization inhibitor. Reduces STOML3 cluster size in the plasma membrane. Decreases mechanically-induced Piezo1 but not ASIC3 current amplitudes in N2a cells and cultured mouse sensory neurons in vitro. Subcutaneous administration in mice reversibly silences touch receptor activity and inhibits paw withdrawal reflex in a mouse neuropathic pain model.

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
