Long-Term Effects of In Vivo Administration of An Anti-VLA-4 Antibody (natalizumab) on Mobilization of Committed and Primitive Hematopoietic Progenitor Cells In Humans
Abstract:2264
The alpha4 beta1 integrin (VLA-4) exert a critical role on hematopoiesis by confining hematopoietic stem cells (HSC) and progenitor cells (HPC) within the niche. Previous preclinical studies have pointed out this role showing that HPCs can be mobilized by in vivo administration of a blocking anti-VLA-4 antibody (Ab) (Papayannopoulou et al, 1993). Very recently, two papers (Bonig et al, 2008; Zohren et al, 2008) have shown that such Ab exhibits a similar effect in humans for one month after … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
