Unexpected link between an antibiotic, pannexin channels and apoptosis
2014
The pannexin 1 channel on the plasma membrane of apoptotic cells mediates the release of find-me molecular signals to attract phagocytic cells for clearance of the apoptotic cells; here the quinolone antibiotic trovafloxacin is identified as a direct inhibitor of pannexin 1, which results in dysregulated fragmentation of apoptotic cells and may partly explain quinolone toxicity.
