B-lymphocyte

a type of LYMPHOCYTE that is formed in the marrow and passed to the lymph glands, producing IMMUNOGLOBULINS (antibodies).

B-lymphocytes produce immunoglobulins as a response to infection, cytokines as immunoregulatory cells, and as antigens they participate in T-B cooperation [2, 3].
Some stay there and develop into B-lymphocytes, while others head to the thymus and become T-Iymphocytes.
This is an extremely uncommon finding, as the tropism of EBV for B-lymphocyte has been associated with B-cells cancers, including Burkitt, Hodgkin, and diffuse large cell lymphomas [14,15]; conversely EBV-positive T-cell lymphoma is exceedingly uncommon in western populations and has been attributed either to a possible antiapoptotic action exerted by the viral DNA hosted in the infected T-cells and/or to signals transmitted by some viral proteins such as Latent Membrane Protein 1 causing the continuous stimulation of members of the TNF receptors [2,16].
When SAP is bound to the cytosolic SLAM, it is thought to enhance T- and B-lymphocyte proliferation, CD8+ T cell activation by antigen-presenting B cells, T-lymphocyte cytokine secretion, and B-lymphocyte antibody production [2, 3].
Among the inflammatory cells, there were less B-lymphocytes (CD20 positive) than T-lymphocytes (CD5 positive).
Humoral immunity is dependent on a full repertoire of mature B-lymphocytes capable of adequately mounting a primary and secondary immune response.
Follicular lymphoma is a type of non-Hodgkin lymphoma and develops when the body makes abnormal white blood cells that fight infection, called B-lymphocytes. It can be slow-growing and does not always need to be treated straight away but when treatment is needed, it usually involves a combination of chemotherapy and a monoclonal antibody called rituximab.
The IBDV actively replicates in B-lymphocytes that found in medullary region of bursa of Fabricius (BF) which its target.
PRTX-100 binds to human B-lymphocytes and macrophages and modulates immune processes pertaining to inflammation seen in autoimmune diseases.

Blood from patients and control individuals randomly selected from the individuals recruited at the Neurology Clinic was used for Epstein-Barr virus (EBV) transfection of B-lymphocytes, EO patients (n = 10), LO patients (n = 10), and controls (n = 10).
