Expression of cellular isoform of prion protein on the surface of peripheral blood lymphocytes among women exposed to low doses of ionizing radiation.

Ionizing radiation affects the expression of adhesive and co-stimulatory molecules in lymphocytes. The physiological function of cellular isoform of prion protein (PrPc) is little known. Evidences indicate a link between lymphocytes activation and PrPc expression on their surface; however, no direct effect of radiation on PrPc level in these cells was investigated.
