- TREK-1 exists in both central nervous system neurons and peripheral sensory neurons. Central effects relate to pain processing in the brain and spinal cord. Peripheral effects relate to pain signal generation at injury sites.
- The binding characteristics of PE-22-28 may favor central effects. Access to peripheral neurons requires crossing biological barriers that central penetration does not. Dosing studies might show different thresholds for central versus peripheral effects.
- For researchers studying pain, this selectivity matters. A compound that affects one component of pain processing without affecting others can be a valuable tool for dissecting mechanisms. PE-22-28 might selectively probe central pain processing while leaving peripheral generation intact.
