Overview. Follicular B cells are the main B cell subset in both mice and humans. A small subset of transitional 2 (T2) B cells mature in the bone marrow into follicular B cells, but most immature B cells migrate to the spleen, where they mature into either follicular B cells or marginal zone B cells. Abstract. The mechanisms that regulate germinal center (GC) B cell responses in the spleen are not fully understood. Here we use a combination of pharmacologic and genetic approaches to delete SIGN-R1 + marginal zone (MZ) macrophages and reveal their specific contribution to the regulation of humoral immunity in the spleen.

However, a number of converging observations revealed that two B-cell subsets, marginal zone (MZ) and B1 cells, exhibit unique developmental and functional characteristics, and can contribute to Nodal marginal zone B-cell lymphoma: This is a rare disease. It starts and usually stays in the lymph nodes, although lymphoma cells can also sometimes be found in the bone marrow. This lymphoma tends to be slow-growing (although not usually as slow as MALT lymphoma), and is treated similarly to follicular lymphoma. Figure 3 | MZ B cells and natural immunity function early in blood-borne antigen removal. After most of the antigen has been removed by early innate mechanisms, natural immunity which involves marginal-zone (MZ) and B1 B cells, natural killer T (NKT) cells and some T cells covers the period before the adaptive immune response is established.
