Abstract
Temperature increase is an integral part of Leishmania life cycle, and plays a major role in stage transformation. Analysis of the temperature‐dependent pattern of protein synthesis on two‐dimensional gel electrophoresis shows that, in addition to the conserved heat‐shock type of response in which expression of the major 70‐kDa and 83‐kDa heat‐shock proteins is observed, a group of low‐molecular‐mass (17–40 kDa) proteins is induced in promastigotes of Leishmania mexicana amazonensis at elevated temperatures. Immuno‐gold labelling with antibodies raised against the heat‐induced 22‐kDa proteins was localized mainly in the mitochondrion of Leishmania parasites, though labelling was observed also in the nucleus. The correlation of this finding with various reports on induction of mitochondrial enzymes in response to temperature stress in other organisms is discussed.
