Marginal zone lymphoma (MZL) is a group of indolent (slow growing) NHL B-cell lymphomas, which account for approximately eight percent of all NHL cases. The average age at diagnosis is 60 years, and it is slightly more common in women than in men.

The clinicopathologic entities include (1) extranodal marginal zone MALT lymphoma, (2) nodal marginal zone lymphoma (MZL), and (3) splenic marginal zone lymphoma (MZL). To the Editor.—Nodal marginal zone B-cell lymphoma (NMZL) has recently been recognized in the World Health Organization (WHO) lymphoma classification1 as a separate clinical and pathologic entity. 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. 😍🖼Animated Mnemonics (Picmonic): https://www.picmonic.com/viphookup/medicosis/ - With Picmonic, get your life back by studying less and remembering more.

Studies on an 'old', but poorly characterized, B-cell subset--the naive, marginal-zone (MZ) B-cell subset--over the past two years have spawned an avalanche of data that encompass the generation and function of these cells. 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 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.

It starts and usually stays in the lymph nodes, although lymphoma cells can also sometimes be found in the bone marrow.

Muri et al. demonstrate that B1 and marginal zone (MZ) B cells but not follicular (Fo) B2 cells require Gpx4 during homeostasis and antibody responses. Mechanistically, B1 and MZ B cells display increased lipid metabolism, sensitivity to lipid peroxidation, and ferroptosis in comparison to Fo B cells.

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.

Marginal zone B cells in mice are located in the outer white pulp of the spleen between the marginal sinus and the red pulp, which allows them to rapidly respond to blood-borne pathogens and participate in both T cell-independent and T cell-dependent immune responses.

There is limited knowledge about the human counterparts of these cells.

2011-12-13 · B lymphocytes were initially thought to only play a role in the adaptive 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.

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.

termination three sub-populations of CD21+ cells were analyzed: follicular dendritic cells (FDc, CD21+CD19-CXCR5-); marginal zone B cells (MZBc,

Resting B2 B cells (these are follicular (FO) and marginal zone (MZ) B cells) express membrane bound IgM, the B cell receptor ( BCR) Sep 14, 2013 Marginal zone lymphoma (MZL) is the third most common B-cell non-Hodgkin lymphoma. It consists of three different entities, as defined by the A, Splenic marginal zone lymphoma. Mature nuclear features are present, and many cells have B cells derived from a wild-type animal are able to differentiate and localize to the marginal zone in Pyk-2–deficient animals.
