Antigens of activated rat T lymphocytes including a molecule of 50,000 Mr detected only on CD4 positive T blasts

Molecular Immunology, 1987
Mouse monoclonal antibodies (MAbs) have been prepared against rat T cell blasts. One MAb called MRC OX-40 recognized an antigen that differed from any previously described in that its expression was detected only on T blasts that also expressed the CD4 antigen.

Herpes simplex virus type 1 can either suppress or enhance human immunodeficiency virus type 1 replication in CD4‐positive T lymphocytes

Journal of Medical Virology, 2003
AbstractIt was proposed recently that CEM CD4‐positive T cells infected chronically by herpes simplex virus type 1 (HSV‐1) and human immunodeficiency virus type 1 (HIV‐1) (CEMHSV/HIV) may be used as a model for studying HIV/HSV interactions. To ascertain whether HSV‐HIV coinfection of T lymphocytes has a role in promoting progression of lentiviral ...

A Review of CD4 Positive T Lymphocytes Counts among HIV Positive Patients Attending a Nigerian Teaching Hospital

British Microbiology Research Journal, 2015
Aims and Objectives: To determine the baseline CD4 positive T lymphocytes count of HIV/AIDS treatment naive adults clients presenting for the first time treatment in Benue State University Teaching Hospital. Subjects and Methods: A total of 700 subjects age between 18 years to 70 years, were recruited for the study, comprising 600 HIV sero-positive ...

Activated CD4-positive T-lymphocytes and impaired cell-mediated immunity in patients with carcinoma of the urinary bladder with schistosomiasis

Cancer, 1990
Patients with schistosomiasis of the urinary bladder (SB) associated with carcinoma of the bladder (SCB) or carcinoma of the prostate (SCP) have a variety of immunologic abnormalities, including the presence of HLA-DR+ and interleukin-2 receptor-positive (IL-2R+) T-lymphocytes in circulating blood.

Profiles of cytokines produced by CD4-positive T lymphocytes stimulated by anti-CD3 antibody in patients with chronic hepatitis C

Journal of Gastroenterology, 1998
Helper T cells (Th) are classified as type 1 (Th1) and type 2 (Th2) according to the cytokines they produce; interferon-gamma is produced by Th1, and interleukin-4 by Th2. We counted the circulating CD4-positive Th cells that produce interferon-gamma or interleukin-4 with an enzyme-linked immunospot assay.

MOBILIZATION OF T LYMPHOCYTES FOLLOWING CARDIAC TRANSPLANTATION

Transplantation, 1992
Modified limiting dilution analysis (LDA) techniques were used to evaluate the mobilization of antigen-stimulated helper T lymphocytes (HTL) and cytotoxic T lymphocytes (CTL) following allogeneic heterotopic cardiac transplantation. These modified LDA techniques allow a quantitative comparison of T cells that have been stimulated by antigen in vivo ...

Circulatory CD4-Positive T-Lymphocyte Imbalance Mediated by Homocysteine-Induced AIM2 and NLRP1 Inflammasome Upregulation and Activation Is Associated with Human Abdominal Aortic Aneurysm

Journal of Vascular Research, 2020
<b><i>Introduction:</i></b> CD4-positive T lymphocytes (CD4 cells) play a significant role in human abdominal aortic aneurysm (AAA). However, we know little about the role of the different CD4 subtypes. <b><i>Objective:</i></b> We aimed to discover the circulatory CD4 phenotypic marker profile and the ...

CD4-positive T lymphocytes are required for the generation of the primary but not the secondary CD8-positive cytolytic T lymphocyte response to herpes simplex virus in C57BL/6 mice

Cellular Immunology, 1991
To understand the cellular basis for recovery from HSV infection, it is critical to identify functional interactions between HSV-specific T lymphocyte subpopulations involved in the generation of the optimal response. To this end, the requirement for CD4+ (L3T4+) T lymphocytes in the development of the primary and secondary CD8+ (Lyt-2+) cytolytic T ...

Quantification of CD4-positive T lymphocytes

1995
Abstract Introduction The central lesion in HIV-induced immunodeficiency is the functional and numerical decrease in the CD4-positive population of T lymphocytes. Progressive loss of this key lymphoid population is associated with an increasing range and severity of cellular immunodeficiency and predisposition to ...

Human T lymphocytes expressing the C3b/C4b complement receptor type one (CR1, CD35) belong to Fcγ receptor-positive CD4-positive T cells

Cellular Immunology, 1989
The phenotypic characteristics of human T lymphocytes expressing the C3b/C4b complement receptor type one (CR1, CD35) were investigated using dual-color surface immunofluorescence and cytofluorometric analysis of stained peripheral blood mononuclear cells (PBMC) from normal individuals.
