Expression of Green Fluorescent Protein as a Marker for Effects of Antileishmanial Compounds In Vitro

Abstract
TransgenicLeishmania infantumpromastigotes, which constitutively express green fluorescent protein (GFP) in their cytoplasm, were used to monitor the effects of antileishmanial compounds in real time. The GFP-based assay provided a reliable measure of drug-induced inhibitory effects on protein expression, resulting in a dynamic picture of the responses of leishmanial promastigotes to the compounds tested.
