Abstract

 

Previous studies   have demonstrated that overexpression of myocardial   heat shock protein (HSP720) in transgenic rats or mice   correlates with reduced infarct size and enhanced myocardial function, following cardiac ischemia. In the present study, using immunohistochemical technique and monoclonal HSP72 antibody we provide anatomical mapping of HSP72 in CNS in rats genetically modified to overexpress HSP72. In this strain of animals the highest expression of HSP72 was found in the following structures i) brain: nucleus caudatus, hippocampal CA1 region, cerebral cortex (layers V-VI), occasionaly also in Purkinje cells of cerebellum and in ii) spinal cord: superficial dorsal horn   (laminae II-IV), a-motoneurons, dorsal column; ascending pathways

 - fasciculus gracilis, fasciculus cuneatus and descending pathways - corticospinal tract. These results demonstrate the ability of adenoviral - HSPi construct to transfer and achieve permanent overexpression of inducible HSP72 in specific CNS regions. This regional specificity of HSP72 expression also suggests that this strain of animals represents a valuable experimental tool to define a potential protective role of HSP72 in a variety of pathological conditions such as ischemia, trauma or neuronal excitotoxicity.
