Background
CD93 or C1q receptor 1 (C1qR) is an about 120 kDa O-sialoglycoprotein that within the hematopoietic system is selectively expressed on cells of the myeloid lineage. CD93/C1qR is a highly glycosylated transmembrane protein expressed on monocytes; neutrophils; endothelial cells; and stem cells. CD93 was originally identified as a myeloid cell-surface marker and subsequently associated with an ability to modulate phagocytosis of suboptimally opsonized immunoglobulin G and complement particles in vitro. CD93/C1qR; a receptor expressed during early B-cell development; is reinduced during plasma-cell differentiation. High CD93/CD138 expression was restricted to antibody-secreting cells both in T-dependent and T-independent responses as naive; memory; and germinal-center B cells remained CD93-negative. CD93 was expressed on (pre)plasmablasts/plasma cells; including long-lived plasma cells that showed decreased cell cycle activity; high levels of isotype-switched Ig secretion; and modification of the transcriptional network. CD93 is important for the maintenance of plasma cells in bone marrow niches.
