Phytohemagglutinin (PHA) renders human peripheral T lymphocytes competent to replicate their DNA and divide. The stimulation of peripheral T cells of the T4 phenotype by PHA, which appears to be a transcription-dependent event, leads to the production and release of lymphokines supporting proliferation and differentiation of human pluripotent stem ...

The human T-cell lymphotropic virus type 1 (HTLV-1) is the causative agent of adult T-cell leukemia/lymphoma (ATLL), a disorder in which peripheral blood and multiple organs are infiltrated by malignantly transformed T lymphocytes. We investigated the nature of pulmonary disease in a patient with serologic evidence of HTLV-1 infection.

Abstract Murine CD4+ T cell clones have been classified into at least two subsets, Th1 and Th2, on the basis of their distinct lymphokine secretion profiles and functions. In the present study, we compared the functional responses of Th1 and Th2 clones to Ag presentation by splenic B cells and peritoneal macrophages.

We have studied by flow cytometric analysis the antigen specific activation of CD4+ (helper/inducer) T lymphocytes by purified human thyroid peroxidase (TPO). Peripheral blood mononuclear cells were obtained from 26 patients with Graves' disease (GD), 16 with Hashimoto's thyroiditis (HT), 7 with nontoxic nodular goiter (NG), and 14 normal subjects (N).

Abstract The CD4+ helper/inducer T cell population is comprised of functionally distinct subsets identifiable by the HB11 (anti-CD45R) mAb. We have previously shown that the cells that provide help for antibody production express the CD4+CD45R- phenotype. In contrast, CD4+ CD45R+ cells have minimal, if any, helper cell functions; rather,

Preferential activation of helper/inducer T lymphocytes in autoimmune chronic active hepatitis.
Clinical and experimental immunology, 1987We found a significant increase of activated circulating T lymphocytes expressing interleukin 2 receptor (IL-2r) (mean +/- s.e.m. 11.0 +/- 1.1%) or DR antigen (5.0 +/- 0.49%) in patients with autoimmune chronic active hepatitis (CAH) starting in childhood when compared to healthy controls (0.14 +/- 0.09%, P less than 0.001 and 2.8 +/- 0.06%, P less ...

• Human papillomavirus-induced infections may be associated with cellular immunodeficiency. However, very little is known about the dysfunctional interactions among T lymphocytes, B lymphocytes, and antigen-presenting cells. A 30-year-old heterosexual man with a 10-year history of persistent multiple refractory flat wart lesions containing human ...

Cellular infiltrates in new and old lesions in two cases of human T-cell leukemia virus associated myelopathy (HAM) were analyzed with anti-CD3 antibody and OPD4 antibody recognizing CD4 + CD45RO + T lymphocytes. A subset of CD4 lymphocytes with helper/inducer function and labeled with OPD4 constitutes up to 65% of CD3 cells in new lesions in the pons ...
