ABSTRACT:
Methods and reagents for effecting transgene expression in Hepatic Stellate Cells (HSC) comprising a 2.2 kb fragment of the promoter region of the Glial Fibrillary Acidic Protein (GFAP) gene, said construct being up-regulated by pro-fÊbronetic cytokines such as TGF-beta 1 in a dose and time dependent manner, and uses thereof.
