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.

The clinicopathologic entities include (1) extranodal marginal zone MALT lymphoma, (2) nodal marginal zone lymphoma (MZL), and (3) splenic marginal zone lymphoma (MZL). Nodal marginal zone B-cell lymphoma (NMZL) is a primary nodal B-cell lymphoma that shares morphologic, immunophenotypic, and genetic characteristics with extranodal marginal zone lymphoma (MZL) and splenic MZL, but without those specific localizations at presentation. 2017-07-14 Marginal-zone B-cell lymphoma of extranodal mucosa-associated lymphoid tissue type: molecular genetics provides new insights into pathogenesis.

Chanudet E, Zhou Y, Bacon CM, Wotherspoon AC, Muller-Hermelink HK, Adam P, Dong HY, de Jong D, Li Y, Wei R, Gong X, Wu Q, Ranaldi R, Goteri G, Pileri SA, Ye H, Hamoudi RA, Liu H, Radford J, Du MQ. Marginal zone (MZ) B cells play important roles in the early phases of humoral immune responses. In addition to possessing an inherent capacity to rapidly differentiate into antibody secreting cells, MZ B cells also help to regulate the fate of both T-independent and T-dependent blood-borne antigens in the spleen.

Part of the immune surveillance is carried out by Sammanfattning: B cells emerge from the bone marrow as transitional (TS) B cells that differentiate through T1, T2, and T3 stages to become naive B cells. Sammanfattning: Human memory B cells and marginal zone (MZ) B cells share common features such as the expression of CD27 and somatic mutations in their as marginal zone (MZ) B cells, and little is known about the mechanisms that control AICD during innate B cell responses to Toll-like receptor (TLR) activation.

is a low-grade B-cell NHL composed of small, monocytoid, and lymphoplasmacytoid cells and mature plasma cells. 226, 227 Many cases are associated with infectious 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.

Marginal zone B cell development is driven by a weak B cell receptor (BCR) signal, along with Notch2 signaling, and BAFF R-mediated canonical NF kappa B signaling. Unlike follicular B cells, marginal zone B cells in mice are immobile, appear to have a long lifespan, and can rapidly mature into plasma cells. that antibody-producing cells (B cells) play a major role in this disease and we wanted to investigate in more detail the role of two groups of B cells – the marginal zone B cells (MZB) and the follicular B cells (FOB) in the initiation of the arthritis. Both cell types are found in MZ B cells are CD21/CD35 + as well as IgM +, CD23-, and IgD low. It should be noted that MZ precursor cells are IgD high and CD23 + 4,5,6. Fol B cells are CD21/35neg-low, IgM +, CD23 +, and IgD high.

Their principal functions are participation in quick responses to blood-borne pathogens and secretion of natural antibodies.
