What is the marginal zone B cell?

The term marginal zone B cell was developed from the fact that these cells reside in the marginal zone of the spleen. It is here that bloodborne antigens are filtered through the marginal zone synoids of the spleen.See all results for this questionWhat is marginal zone in lymph nodes?The marginal zone is most easily visualized in the spleen and is not easy to appreciate in normal lymph nodes outside the abdominal region. Normal marginal zone B cells may differentiate into either monocytoid B cells or plasma cells.See all results for this questionWhat is a normal marginal zone?The normal marginal zone is the area circumferentially adjacent to the mantle zone and distal to the germinal center of a reactive (secondary) follicle.

SMZL was previously termed splenic lymphoma with circulating villous lymphocytes.Splenic Marginal Zone Lymphoma | Signs, Symptoms marginal zone signThe exact cause of splenic MZL is generally unknown. As with most cancers, a family history increases a patientís risk to some extent. Occupational exposures, notably pesticides, also increase the risk of SLL. In fact, the Midwest, where farming is prevalent, has the highest incidence of NHL in the United States. Hepatitis C infection has also been associated with the development of splenic MZL in about one-third of cases.See more on knowcancer marginal zone sign
