Web28 sep. 2024 · IgM antibodies (Abs) are thought to play a major role in humoral immunity but only at the early stage of the primary immune response. However, two subsets of IgM+ … Human B1 cells have been found to have marker profile of CD20+CD27+CD43+CD70- and could either be CD5+ or CD5-, which has been debated since. CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5 ) and B-1b (CD5 ) subtypes. Unlike B-1a B cells, the B-1b subtype can be generated from precursors in …
