CD4+ T Cells at the Center of Inflammaging [PDF]

Cell Metabolism, 2020
Bharath et al., 2020 report that CD4+ T lymphocytes from aged individuals exhibit defective mitochondrial autophagy, resulting in altered redox metabolism and upregulation of TH17 cytokines, which in turn may contribute to aging-associated chronic inflammation or "inflammaging." Of note, the antiaging drug metformin reverses this autophagy defect and ...

The Era of Cytotoxic CD4 T Cells

Frontiers in Immunology, 2022
In 1986, Mosmann and Coffman identified 2 functionally distinct subsets of activated CD4 T cells, Th1 and Th2 cells, being key in distinct T cell mediated responses. Over the past three decades, our understanding of CD4 T cell differentiation has expanded and the initial paradigm of a dichotomic CD4 T cell family has been revisited to accommodate a ...

CD4 T cell cooperation is required for the in vivo activation of CD4 T cells [PDF]

International Immunology, 2009
We address here the role of CD4 T cell cooperation in the activation of CD4 T cells. Administration of aggregated hen egg lysozyme (HEL) without microbial adjuvant to BALB/c mice normally generates cytokine-producing CD4 T cells specific for the HEL major peptide, HEL(105-120), as well as CD4 T cells specific for HEL non-major peptides.

STAT5 and CD4+ T Cell Immunity [PDF]

F1000Research, 2017
STAT5 plays a critical role in the development and function of many cell types. Here, we review the role of STAT5 in the development of T lymphocytes in the thymus and its subsequent role in the differentiation of distinct CD4+helper and regulatory T-cell subsets.

Time-restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance. [PDF]

FEBS Open Bio
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Tracking Virus-Specific CD4+ T Cells during and after Acute Hepatitis C Virus Infection [PDF]

, 2007
Background. CD4+ T cell help is critical in maintaining antiviral immune responses and such help has been shown to be sustained in acute resolving hepatitis C.

Modulation of the CD8+-T-cell response by CD4+ CD25+ regulatory T cells in patients with Hepatitis B virus infection [PDF]

, 2005
CD4+ CD25+ regulatory T cells have been shown to maintain peripheral tolerance against self and foreign antigens. In this study we analyzed the effect of circulating CD4+ CD25+ T cells on CD8+-T-cell responses of patients with chronic and resolved ...

First-in-human phase 1 study of IT1208, a defucosylated humanized anti-CD4 depleting antibody, in patients with advanced solid tumors

Journal for ImmunoTherapy of Cancer, 2019
Background Transient CD4+ T cell depletion led to the proliferation of tumor-specific CD8+ T cells in the draining lymph node and increased infiltration of PD-1+CD8+ T cells into the tumor, which resulted in strong anti-tumor effects in tumor-bearing ...

CD4+ regulatory T cells

Current Opinion in Immunology, 2001
There is now compelling evidence that CD4(+) T cells that specialize in the suppression of immune responses play a key role in the control of immune pathology. Recently, there have been a number of reports that have provided information on the generation of CD4(+) regulatory T cells in the thymus and in the periphery.

T helper1/T helper2 cells and resistance/susceptibility to Leishmania infection : is this paradigm still relevant? [PDF]

, 2012
Work in large part on Leishmania major in the 1980s identified two distinct apparently counter-regulatory CD4 T cell populations, T helper (h)1 and Th2, that controlled resistance/susceptibility to infection respectively.
