Unusual Lack of the Epitope Recognized by OKT4 on the Helper/Inducer T Lymphocytes
Pediatrics International, 1985AbstractLack of the epitope recognized by OKT4 monoclonal antibody on the helper/inducer T lymphocytes in a 14‐year‐old boy with IgA nephritis is described.The lymphocytes reacted normally with OKT3 /Leu4 and OKT8/αLeu2a monoclonal antibodies but not with OKT4 monoclonal antibody.

T lymphocytes can be divided into two main phenotypic populations, CD4 and CD8. These can be further subdivided into 2H4, 4B4, or UCHL1 subsets by appropriate monoclonal antibodies. We have investigated these subsets in the synovial fluid of patients with rheumatoid arthritis and have found (i) a virtual absence of CD4+ 2H4+ and the marked reduction of

A panel of previously characterized monoclonal antibodies: B67.6, OKT3, OKT4, B53.4, Leu3a, OKT8, Leu2a, OKM1, M12 and B52.1 were used as a probe to assess mononuclear cells in peripheral blood (PB), lymph nodes (LN) and spleens of untreated patients with Hodgkin's disease (HD).

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 ...

AbstractThe mechanisms which lead to the accumulation of T lymphocytes into inflammatory lesions are not clearly understood. We have previously shown that synovial CD4 T lymphocytes are mostly CDw29UCHL1 (helper‐inducer cells) and very few carry the CD45R antigen which identifies the suppressor‐inducer subset.

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 To test the hypothesis that resting and previously activated B lymphocytes differ in their proliferative and differentiative responses to various Th cell-derived stimuli, we have examined the interactions of purified small (resting) and large (activated) murine B cells with rabbit Ig-specific Th1 and Th2 clones in the presence ...

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,
