Double-stranded rna dependent protein kinase derived peptides to promote proliferation of cells and tissues in a controlled manner

摘要

This invention relates to double-stranded RNA dependent protein kinase (PKR) peptide antagonists. More specifically, the invention relates to compositions and methods for antagonizing activation of double-stranded RNA dependent protein kinase (PKR) to stimulate eukaryotic cell proliferation. The invention relates to compositions and methods to inhibit activation of double-stranded RNA dependent protein kinase (PKR) to stimulate cell proliferation under conditions of cell cycle arrest, quiescence, reduced growth or cell death. The invention also relates to methods of protecting cells from HIV-1 pathogenesis using inhibitors of PKR.
