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.

T1 - Marginal-Zone B-Cells are main producers of IgM in humans, and are reduced in patients with autoimmune vasculitis. AU - Appelgren, Daniel. AU - Eriksson, Per. AU - Ernerudh, Jan. AU - Segelmark, Mårten. PY - 2018/10/2. Y1 - 2018/10/2

There is limited knowledge about the human counterparts of these cells. We therefore investigated functions of MZ-like B-cells and the frequency of circulating MZ-like and B1-like B-cells in healthy controls (HC), as well as in 2018-09-29 · B-cells and T-cells are two types of lymphocytes that can develop into lymphoma. Marginal zone lymphoma (MZL) is classified as a group of slow-growing, non-Hodgkin’s B-cell lymphomas . There are Marginal zone B cells show a high subpopulation with unmasked CD22. In three‐color staining of C57BL/6 splenocytes, two B cell populations were gated as indicated (MZ = marginal zone B cells, M = mainly mature B cells) and the staining with NeuGcα2,6Gal–SAAP is shown in histograms. The splenic marginal zone (SMZ) is a unique B-cell compartment that contains B cells with a high surface density of IgM and complement receptor 2 (Cr2 or CD21), and which exhibits a rapid activation and immunoglobulin secretion in response to blood-borne T-independent (TI) antigens.

Marginal zone B-cell lymphomas, also known as marginal zone lymphomas (MZLs), are a heterogeneous group of lymphomas that derive from the malignant transformation of marginal zone B-cells. Marginal zone B cells are innate lymphoid cells that normally function by rapidly mounting IgM antibody immune responses to antigens such as those presented by infectious agents and damaged tissues.

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.

Considerable progress has been made regarding the mechanisms involved in marginal zone B cell development in the mouse. Many of the molecular events that participate in the retention of this lineage of B cells in the marginal zone have been identified. Marginal zone (MZ) B cells comprise a subset of innate-like B cells found predominantly in the spleen, but also in lymph nodes and blood. Their principal functions are participation in quick responses to blood-borne pathogens and secretion of natural antibodies. 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.

B-lymphocytes were initially thought to only play a role in the adaptative branch of immunity. 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 innate immune responses. 2021-04-05 · In mice, B1 and marginal zone (MZ) B-cells play an important role in prevention of autoimmunity through production of regulatory cytokines and natural antibodies.
