lüll Infection-associated lymphomas derived from marginal zone B cells: a model of antigen-driven lymphoproliferation Suarez F; Lortholary O; Hermine O; Lecuit MBlood 2006[Apr]; 107 (8): 3034-44Non-Hodgkin lymphomas develop from nodal and extranodal lymphoid tissues. A distinct subset of extranodal lymphomas arising from B cells of the marginal zone (MZ) of mucosa-associated lymphoid tissue (MALT) or spleen has been individualized. Growing evidence indicates that MZ lymphomas are associated with chronic antigenic stimulation by microbial pathogens and/or autoantigens. The list of microbial species associated with MZ lymphoproliferations has grown longer with molecular investigations and now comprises at least 5 distinct members: H. pylori, C. jejuni, B. burgdorferi, C. psittaci, and hepatitis C virus (HCV), which have been associated with gastric lymphoma, immunoproliferative small intestinal disease, cutaneous lymphoma, ocular lymphoma, and spleen lymphoma, respectively. A pathophysiologic scenario involving chronic and sustained stimulation of the immune system leading to lymphoid transformation has emerged. It defines a distinct category of infection-associated lymphoid malignancies, in which the infectious agent does not directly infect and transform lymphoid cells, as do the lymphotropic oncogenic viruses Epstein-Barr virus (EBV), human herpesvirus 8 (HHV8), and human T-lymphotropic virus 1 (HTLV-1), but rather indirectly increases the probability of lymphoid transformation by chronically stimulating the immune system to maintain a protracted proliferative state.|*Cell Proliferation[MESH]|Antigen Presentation/*immunology[MESH]|Antigens, Bacterial/*immunology[MESH]|B-Lymphocytes/*immunology/microbiology/pathology[MESH]|Bacterial Infections/complications/*immunology/pathology[MESH]|Cell Transformation, Neoplastic/immunology/pathology[MESH]|Humans[MESH]|Lymphoid Tissue/immunology/microbiology/pathology[MESH]|Lymphoma, B-Cell/etiology/*immunology/pathology[MESH]|Models, Immunological[MESH] |
