Background: It has previously been shown that propofol in clinically relevant concentrations induces a calcium-dependent conformational change in the cytoskeleton. The aim of this study was to further clarify the effect of propofol on the actin cytoskeleton and to determine if this conformational change is mediated by the interaction between the GABAA-receptor and propofol. Methods: Primary cultured cortical neurons from newborn rats were treated with propofol 3 µg·ml-1 in a time-response titration, with and without preincubation with the GABAA-receptor antagonist, bicuculline. Actin-protein content was detected by Western blot analysis and the cellular content of F-actin measured by a spectrophotometric technique. Results: Propofol triggers a relatively slow statistically significant increase in the intracellular F-actin content, maximum after 20-min incubation (160%±16.3) (mean±SEM) P
