BACKGROUND: Human macrophages (Mφ) express low levels of CD4 glycoprotein, which is constitutively recycled, and 40-50% of its localization is intracellular at steady-state. Although CD4-interacting proteins in lymphoid cells are well characterised, little is known about the CD4 protein interaction-network in human Mφ, which notably lack LCK, a Src family protein tyrosine kinase believed to stabilise CD4 at the surface of T cells. As CD4 is the main cellular receptor used by HIV-1, knowledge ...Expand abstract
