Interactions with P-glycoprotein in HAPI microglia only partially explain the LPS-mediated changes in saquinavir accumulation. (A) Following 24 hours LPS incubation (10 ng/ml), accumulation of [3H]saquinavir (50 μM) at one hour (37°C) was measured in the presence and absence of the P-glycoprotein inhibitor PSC833 (5 μM). (B) By subtracting the LPS-untreated values (control and PSC833 inhibited; white bars) from the LPS-treated cells (LPS control and PSC833 inhibited; black bars) the P-glycoprotein specific/sensitive component of transport was determined. Each data point represents mean ± SE of at least three separate experiments with three replicates included per experiment; *P < 0.05, significantly different from LPS-untreated control cells.
