Abstract:

Background and Aims: Human lymphotropic virus type-1 (HTLV-1) causes various diseases such as adult T-cell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy/tropical spastic paraperesis (HAM / TSP) in humans. The main goal of this study is to compare Iranian protease subtypes structure of this virus (HTLV-1) to samples collected from other part of world in order to understand their differences. Materials and Methods: During 1394 -1395, 10 blood samples taken from HTLV-1 virus infected individuals. Samples went through polymerase chain reaction (PCR) process.The obtained products were sequenced and phylogenetic analysis were done. The second and third structures of these sequences were obtained by using a specialized websites. Results: The Iranian samples were completely exposed in to the cluster of Cosmopolitan subtype. The result of first structure alignment of protease protein in different subtypes of the virus, suggested some differences in the gene of interest. The conversion of the first structure to second and third structures and respectively pairwise and multiple alignment showed no significant difference in the protease protein conformation. Conclusions: The comparison of HTLV-1 virus protease protein from Iran and other sequences in the world which were obtained from GenBank shows no significant dissimilarity. This dissimilarity help to design the production of the drug. Therefore, future studies can be targeting a part of the protein and generalize the treatment outcomes to all subtypes circulating. This comparison have beneficiary effect in making the right medication that inhibit the subtypes of the virus in treatment studies of disease developed by this virus.

[The human T-cell lymphotropic virus type 1 (HTLV-1)].

Human T-cell Lymphotropic virus type I (HTLV-1) was the first human retrovirus described. Some time after its discovery a group of diseases were related to this virus, such as, adult T-cell leukemia lymphoma (ATLL), HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) and HTLV-1 associated uveitis (HAU). In the nineties, HTLV-1 was associated to a severe eczema of children, calle...

The Enigma of Human T-Cell Leukemia Virus Type-1 (HTLV-1) Infection in Iran

Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy.  The prevalence of HTLV-I infection varies significantly in different regions of the world.  In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained.  HTLV-1 antibody assay on serum samples was d...

Awareness of laboratory students of Mashhad University of Medical Sciences about human T-cell lymphotropic virus type 1 (HTLV-1)

Introduction: HTLV-1 virus is a human retrovirus and it causes several chronic diseases. So far, there is not any vaccine or satisfactory treatment that has been developed for infections caused by this virus. Moreover, the best way to control the infection is prevention and the best way to prevent it is education. Therefore, our study was conducted to investigate the knowledge and attitudes of ...
