Primitive hematopoietic cells resist HIV-1 infection via p21Waf1/Cip1/Sdi1

1 Feb 2007

Abstract excerpt

Hematopoietic stem cells are resistant to HIV-1 infection. Here, we report a novel mechanism by which the cyclin-dependent kinase inhibitor (CKI) p21(Waf1/Cip1/Sdi1) (p21), a known regulator of stem cell pool size, restricts HIV-1 infection of primitive hematopoietic cells. Modifying p21 expression altered HIV-1 infection prior to changes in cell cycling and was selective for p21 since silencing the related CKIs,...
