Infection of macrophages with functional Slc11a1 yields differences in global gene expression, regulation of metal ions, and infection outcomes


ABSTRACT: Manipulation of zinc at the host-pathogen interface depends on both the identity of the pathogen and the nature of the host cell. In this study, we examine the response of bone marrow derived macrophages from 129S6/SvEvTac mice to infection by Salmonella Typhimurium. Unlike Balb/c and C57BL/6 mice, 129S6/SvEvTac mice possess a functional Slc11a1 (Nramp-1), a phagosomal transporter of divalent cations. We examine the changes in gene expression upon treatment with live or heat killed Salmonella at 2 Hrs and 18 Hrs post infection, and observed widespread changes in metal transport, metal-dependent, and metal homeostasis genes, suggesting significant remodeling of iron, copper, and zinc availability by host cells.
