Secretory Microneme Proteins Induce T-Cell Recall Responses in Mice Chronically Infected with Toxoplasma gondii

mSphere, 2019
Microneme (MIC) proteins play important roles in the recognition, adhesion, and invasion of host cells by Toxoplasma gondii. Previous studies have shown that MIC proteins are highly immunogenic in the mouse and recognized by human serum antibodies.

Sézary Syndrome with CD4/CD8 Double-Negative Neoplastic T Cells in Peripheral Blood

Case Reports in Hematology, 2021
Sézary syndrome is a rare leukemic type of cutaneous T-cell lymphoma characterized by the presence of neoplastic T cells with cerebriform nuclei (Sézary cells) in the skin, lymph nodes, and peripheral blood.

Species heterogeneity in macrophage expression of the CD4 antigen. [PDF]

The Journal of experimental medicine, 1987
The CD4 antigen is expressed on T cells of all mammalian species examined and appears to play an important role in the response of T cells to antigen. In humans, the molecule acts as a receptor for the AIDS virus. Previous studies have demonstrated that M phi in the rat and human also express the CD4 antigen, which is indistinguishable from that on T ...

Involvement of Different CD4+ T Cell Subsets Producing Granzyme B in the Immune Response to Leishmania major Antigens

Mediators of Inflammation, 2014
The nature of effector cells and the potential immunogenicity of Leishmania major excreted/secreted proteins (LmES) were evaluated using peripheral blood mononuclear cells (PBMCs) from healed zoonotic cutaneous leishmaniasis individuals (HZCL) and ...

Regression of canine oral papillomas is associated with infiltration of CD4+ and CD8+ lymphocytes [PDF]

, 2001
Canine oral papillomavirus (COPV) infection is used in vaccine development against mucosal papillomaviruses. The predictable, spontaneous regression of the papillomas makes this an attractive system for analysis of cellular immunity.

CD4+CD25+ TR cells suppress innate immune pathology through cytokine-dependent mechanisms [PDF]

, 2003
Copyright @ 2003 The Rockefeller University PressCD4+CD25+ regulatory T (TR) cells can inhibit a variety of autoimmune and inflammatory diseases, but the precise mechanisms by which they suppress immune responses in vivo remain unresolved.

Intratumor childhood vaccine-specific CD4+ T-cell recall coordinates antitumor CD8+ T cells and eosinophils

Journal for ImmunoTherapy of Cancer, 2023
Background Antitumor mechanisms of CD4+ T cells remain crudely defined, and means to effectively harness CD4+ T-cell help for cancer immunotherapy are lacking. Pre-existing memory CD4+ T cells hold potential to be leveraged for this purpose.

Flow Cytometric Analysis of T, B, and NK Cells Antigens in Patients with Mycosis Fungoides

Journal of Immunology Research, 2015
We retrospectively analyzed the clinicopathological correlation and prognostic value of cell surface antigens expressed by peripheral blood mononuclear cells in patients with mycosis fungoides (MF). 121 consecutive MF patients were included in this study.

Expression of CCR6 on Helicobacter pylori-specific circulating CD4+ T cells

Инфекция и иммунитет
Introduction. Helicobacter pylori can infect human gastric mucosa and cause various pathological conditions. In the blood of H. pylori-infected patients, the level of mature CD4+CCR6+ T-lymphocytes, especially pro-inflammatory CCR6+ T-helper types 1 and ...
