The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...

The lymphoid tissue of the normal colon is compared with that of colons with diverticular disease. Colons with diverticular disease show a significant increase in the number of lymphoid nodules in areas not containing diverticula. Lymphoid-glandular complexes of the colon were studied in relation to diverticular disease. It is suggested that the lymphoid nodules and the lymphoid-glandular compl...

The ability to generate functional artificial lymphoid tissue to induce specific immunity at ectopic sites could offer a potential breakthrough for treatment of diseases such as cancer and severe infection using immunotherapy. Artificial lymphoid tissue could also offer an informative tool to study further lymphoid tissue development and function in vivo. Here, we review the process of secondar...

Objective: Lymphoid enhancer-binding factor-1 (LEF1) is one of the key regulators lymphocyte proliferation and its aberrant expression a prognostic factor for lymphoid or myeloid malignancies. In this study, we focused on LEF1 isoforms in several hematological malignancies found tissue-specific differential full-length (FL)-LEF1 gene tumor suppressor (∆LEF1) variant. Material Method: Fifty-thre...

The major lymphoid tissues in teleost fish are the kidneys, thymus, spleen and mucosa-associatedlymphoid tissue including the skin, gills and intestine. The head of kidney (pronephros) is an importanthaematopoietic organ and has morphological similarities with the bone marrow in higher vertebrates. In thisstudy, during 12 months from August 2002 to July 2003, 120 grass carp (10 fish/month) were...
