BACKGROUND Adult T-cell leukemia (ATL) is an acute malignancy of activated T-cells caused by the human T-cell lymphotrophic virus type-1 (HTLV-1). MATERIALS AND METHODS The effects of non-cytotoxic concentrations of ascorbic acid (AA) were evaluated against HTLV-1 positive and negative cells. The effect of AA on apoptosis and proliferation was evaluated by cell cycle analysis. The role of p53...

A case with the triad of pure red cell aplasia (PRCA), myasthenia gravis, and malignant thymoma is reported. There was a clonal proliferation of T cells within the thymoma, as demonstrated by a T cell antigen receptor (TCR) delta chain gene rearrangement. However, despite a large granular lymphocytosis, clonality could not be shown in the peripheral blood either before or after thymectomy. Ther...

The leprosy spectrum is directly associated with the host immune response to Mycobacterium leprae antigens, which will determine not only the clinical type of disease, but also whether the development of the leprosy reactions (LRs) will occur (Rea & Modlin 1991). Therefore besides being a chronic infection, leprosy can also be regarded as an immunological disease. The leprosy spectrum comprises...

background and aims: the latency-associated transcript (lat) transcribed by latent herpes simplex virus type-1 in neuron cells are able to influence their host cell pathways. while the most of previous studies were focused on anti-apoptotic effects of lat, our investigation is making an effort to explore lat potency on cell cycle pathway in neuroblastoma cell lines. methods: the evaluation of l...

Human T cell lymphotrophic Virus 1 (HTLV-1) is endemic in the Caribbean, parts of South America, West Africa, Asia and Oceania but rare in North America. After a prolonged latency, HTLV-1 is associated with development of acute T cell leukemia/lymphoma (ATL) in 2–5% of infected individuals and HTLV-1-associated myelopathy (HAM) in a smaller percentage. Screening tests do not distinguish between...

Abstract : Foot and Mouth Disease is one of  the important live stocks contagious viral disease caused by Aphtovirus genus ,  that is belong to family RNA virus  picornaviride. The important characteristic of FMD virus is high mutation that give rise to diversity of Antigen in surface of Neutralizing proteins. For this reason FMD virus have 7 distinct serotype and many subtype. Vaccination is o...
