The internalization of Leishmania amastigotes by macrophages is thought to be mediated mainly through opsonization with immunoglobulins (Igs) which bind FcγRs, stimulating the uptake (Morehead et al 2002 & Padigel et al. 2005). Glycoinositol phospholipids (GIPLs) are the most abundant glycolipids on the surface of the amastigote form of Leishmania parasites and Buxbaum and colleagues showed that IgG1 in mice, binds the GIPL molecules on the amastigote stage of L. mexicana to subsequently induced the phagocytosis through FcγRs (Buxbaum 2013).
