Hematological shift in goat kids naturally devoid of prion protein.

ABSTRACT: The physiological role of the cellular prion protein (PrP(C)) is incompletely understood. The expression of PrP(C) in hematopoietic stem cells and immune cells suggests a role in the development of these cells, and in PrP(C) knockout animals altered immune cell proliferation and phagocytic function have been observed. Recently, a spontaneous nonsense mutation at codon 32 in the PRNP gene in goats of the Norwegian Dairy breed was discovered, rendering homozygous animals devoid of PrP(C). Here we report hematological and immunological analyses of homozygous goat kids lacking PrP(C) (PRNP(Ter/Ter) ) compared to heterozygous (PRNP (+/Ter)) and normal (PRNP (+/+)) kids. Levels of cell surface PrP(C) and PRNP mRNA in peripheral blood mononuclear cells (PBMCs) correlated well and were very low in
