Recombinant retroviruses containing the trans activator genes of human T-cell leukemia virus (HTLV) type II and human T-cell lymphotropic virus type III were constructed. The trans activator genes tat II and tat III were inserted into the murine retroviral vector pZIPNEOSV(X)1. Recombinant plasmids were transfected into the psi 2 and psi AM packaging cell lines that produce murine leukemia viri...

Of 78 Gabonese individuals who had received bites from nonhuman primates (NHPs) while hunting, 7 were infected with human T lymphotropic virus (HTLV-1). Five had been bitten by gorillas and were infected with subtype B strains; however, a 12-year-old girl who was severely bitten by a Cercopithecus nictitans was infected with a subtype D strain that was closely related to the simian T 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...

INTRODUCTION A major obstacle in understanding the pathophysiology of lymphedema, the differentiation from other types of edema, and in treatment planing is the difficulty of visualizing lymphatic vessels in human beings [1]. Lymphoscintigraphy is the primary imaging modality. Despite recent refinements in this technology an improved depiction of the lymphatic system with high resolution is des...

While prions probably interact with the innate immune system immediately following infection, little is known about this initial confrontation. Here we investigated incunabular events in lymphotropic and intranodal prion trafficking by following highly enriched, fluorescent prions from infection sites to draining lymph nodes. We detected biphasic lymphotropic transport of prions from the initia...

Retroviruses can be classified according to the morphology of their virion core or according to sequence homologies that become evident after phylogenetic analyses. Human T-lymphotropic virus type 1 (HTLV-1) is a member of the deltatype retrovirus group, other members of which include HTLV types 2, 3 and 4, bovine leukaemia virus (BLV), and simian T-cell leukaemia virus (STLV) types 1, 2 and 3 ...

Summary. The aim of the work was to study possibility and effectiveness antibiotic therapy for appendicular infiltrate using proposed lymphotropic technology. results treatment patients with two studied groups were analyzed. In main group (47 patients), administration antibacterial drugs performed. comparison people) received standard therapy. At same time, it possible reduce period inpatient f...

Adult T-cell lymphoma (ATL) is a hematological malignancy of CD4+ mature T-lymphocytes commonly associated with chronic human T-lymphotropic virus type I (HTLV-1) infection. Chronic HTLV-1 infection induces oncogenic mutations in T-cells, leading to an acute malignant transformation host cells. Atypically, ATL presents dermatological and pulmonary symptoms consistent “smoldering” disease patter...

human t-lymphotropic virus type i (htlv-1) is an endemic virus in iran and other regions that is associated with multiple diseases including adult t-cell leukemia/ lymphoma and a chronic debilitating neuroinflammatory disease, htlv-1-associated myelopathy/tropical spastic paraparesis (ham/tsp). ham/tsp is seen in approximately 2% of htlv-1-infected people with symptoms such as back pain, weakne...
