The global epidemic of AIDS has become one of the most pressing public health emergencies of this century. Initial reports of AIDS date back to 1981. However, current data suggest that AIDS has existed for at least several decades. While both forms of the human immunodeficiency virus (HIV), type 1 and type 2, are retroviruses capable of causing fatal AIDS, infection with the latter generally re...
Retroviruses are commonly associated with neurological disease in animals, for example, inflammatory encephalomyelopathies of sheep (visna virus),' horses (equine infectious anaemia virus), goats (caprine encephalitis/arthritis virus)2 and mice (murine leukaemia virus).3 The first retrovirus shown to be pathogenic in humans was discovered by Gallo's group4 who demonstrated that human lymphotrop...
Human T-cell lymphotropic virus type I (HTLV-I) and human T-cell lymphotropic virus type II (HTLV-II) have been associated with adult T-cell leukemia/lymphoma (ATL) and a rare T-cell variant of hairy cell leukemia, respectively. Direct detection of viral nucleic acid in peripheral blood lymphocytes (PBLs) and infected tissues in carrier patients and those with chronic disease has proven refract...
The ability of molecular clones of human T-cell leukemia virus type I (HTLV-I) to direct the synthesis of infectious virions has not previously been demonstrated. An HTLV-I provirus originating from an adult T-cell leukemia patient was cloned into a plasmid vector and is designated pCS-HTLV. This molecular clone was shown to direct the synthesis of viral mRNA and proteins in transiently transfe...
The presence of a high number of activated T cells in the bloodstream and spontaneous proliferation of peripheral blood mononuclear cells in vitro are striking characteristics of human T-cell leukemia virus type I (HTLV-I) infection. The HTLV-I regulatory protein Tax and the envelope protein gp46 have been implicated in mediating the activation process. In this study, HTLV-I-producing cell line...
Skin diseases ranging from infective dermatitis to cutaneous lymphoma have been associated with human T cell leukemia virus (HTLV) type I. A generalized exfoliative papillated dermatopathy occurred in a rabbit 20 months into a course of chronic HTLV-I infection. Biopsies revealed epidermotropic T cell infiltrates, including Sezary-like cells, that resulted in a pattern mimicking cutaneous T cel...
background human t-lymphotropic virus type i (htlv-i) is one of the health threatening problems in endemic areas and can be transmitted by different routes such as blood transfusion. in order to correct chronic anemia in thalassemia subjects, they may need to get blood units per month. thus, they are at risk of infection with blood-borne viruses such as htlv-i. objectives in the present study, ...
Background and Aims: Human T-lymphotropic virus (HTLV) is a human retrovirus which has been known to cause adult T-cell leukemia/lymphoma and some other inflammatory disorders. Patients with hereditary bleeding diseases are at high risk for these viruses. In this study, we evaluated serological HTLV-I/II infection among these patients in west Azerbaijan of Iran. Material and Methods: We stud...
