T cell ratios in AIDS.

The human T-cell leukemia virus family, adult T cell leukemia, and AIDS.

Human T cell leukemia virus (HTL V) is the name by which we have designated a family of related retroviruses from humans. HTLV type I (HTLV-I) is the name we gave the first human retrovirus isolate. HTLV-I is endemic at low rates in different parts of the world, including southern Japan, the Caribbean, South and Central America, the southeastern United States, and especially in Africa. Seroepid...

Recent Advances in T Cell Signaling in Aging

The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...

Aids Virus Particles from a Cloned T Cell Line

A unique human retrovirus (RV) 1 has been consistently isolated f rom patients with the acquired immune deficiency syndrome (AIDS). Infection o f human T lymphocytes or T lymphocyte lines with the AIDS RV can result in a variety of outcomes ranging from rapid cell death to the integration of functionally inert proviral DNAs (1-3). A typical AIDS RV infection is characterized by the appearance o...

Effects of Dietary Vitamin C, E and Fat on CD4 to CD8 T Cell Ratios in Peripheral Blood of Heat-stressed Broiler Chicks

Specific cutaneous manifestations in adult T cell leukemia/lymphoma

Background and aim: Adult T cell leukemia/lymphoma (ATLL) is an aggresive malignancy which may occur in human T lymphotropic virus1(HTLV1) infected persons. HTLV1 is endemic in Khorasan with prevalence of 2.3% in general population. Since specific cutaneous manifestations of lymphoma may occur in a significant number of patients, we studied ATLL patients in Mashhad.Mate...
