When co-incubated with verapamil, intracellular levels of Act D increased in a concentration-dependent manner, indicating that Act D efflux is reduced in the presence of ABCB1 inhibition (Fig. 3B).
Science
Our findings show that plasma levels of ACT and SLPI are not elevated in subjects with genetic AAT deficiency compared MM controls and do not appear to compensate for the deficiency of plasma AAT.
