Web26 jul. 2002 · We examined ionomycin-induced cell death in LCLC 103H cells, derived from a human large cell lung carcinoma. We detected hallmarks of apoptosis such as membrane blebbing, nuclear condensation, DNA ladder formation, caspase activation, and poly- (ADP-ribose)polymerase cleavage. Web23 mrt. 2016 · Ionomycin-induced hyporesponsiveness is bypassed by IL-2 treatment. IL-2 treatment enhances the functionality of ionomycin induced anergic CD4 + T cells [19, 37]; however, previous reports were contradictory as to whether reduced NK cell responsiveness could be compensated by IL-2 stimulation [7, 13, 22, 38–40].
