Ação dos linfócitos T regulatórios em transplantes T regulatory lymphocytes action in transplants

Revista Brasileira de Hematologia e Hemoterapia, 2008
O sistema imunológico humano possui um significado comum de proteção contra antígenos estranhos com potencialidade patogênica ou não, ativando uma ação coletiva e coordenada entre células e moléculas. Embora sendo um sistema benéfico, deve ser controlado

Loss of chromosome Y in regulatory T cells

BMC Genomics
Background Mosaic loss of chromosome Y (LOY) in leukocytes is the most prevalent somatic aneuploidy in aging humans. Men with LOY have increased risks of all-cause mortality and the major causes of death, including many forms of cancer.

Functional and Molecular Comparison of Anergic and Regulatory T Lymphocytes [PDF]

The Journal of Immunology, 2006
AbstractTolerance in vivo is maintained by multiple mechanisms that function to prevent autoimmunity. An encounter of CD4+ T cells with a circulating self-Ag leads to partial thymic deletion, the development of CD25+ regulatory T cells (Tregs), and functional anergy in the surviving CD25− population.

IL-24 producing regulatory T and B lymphocytes in endometriosis

Frontiers in Immunology
ProblemUnbalanced production of pro- and anti-inflammatory cytokines by immune cells is a hallmark of endometriosis. IL-24, a member of the IL-10 family, is a pleiotropic cytokine produced by both non-immune cells like astrocytes, keratinocytes ...

Clinical and prognostic significance of T-regulatory cells and CD28 expression on T-lymphocytes in patients with immune thrombocytopenia

Онкогематология
Background. The leading role in the control of the immune response and peripheral tolerance is played by T-regulatory cells, as well as costimulatory molecules C28 on T-lymphocytes, which are necessary for effective activation.

RFX transcription factors control a miR-150/PDAP1 axis that restrains the proliferation of human T cells.

PLoS Biology, 2022
Within the immune system, microRNAs (miRNAs) exert key regulatory functions. However, what are the mRNA targets regulated by miRNAs and how miRNAs are transcriptionally regulated themselves remain for the most part unknown. We found that in primary human

Decrease of Tumor-infiltrating Regulatory T Cells Using Pentoxifylline: An Ex Vivo Analysis in Triple-negative Breast Cancer Mouse Model

Iranian Journal of Allergy, Asthma and Immunology, 2022
Triple-negative breast cancer (TNBC) is the most aggressive type of BC with the highest percentage of tumor-infiltrating lymphocytes (TILs). Hence, TIL therapy is considered a promising approach to target TNBC. Depletion of regulatory T cells (Tregs) in

The changes of CD4+CD25+/CD4+ proportion in spleen of tumor-bearing BALB/c mice

Journal of Translational Medicine, 2005
CD4+CD25+ regulatory T lymphocytes (TR) constitute 5–10% of peripheral CD4+ T cells in naive mice and humans, and play an important role in controlling immune responses.

Regulatory T‐lymphocytes mediate amyotrophic lateral sclerosis progression and survival

EMBO Molecular Medicine, 2012
In amyotrophic lateral sclerosis (ALS) mice, regulatory T‐lymphocytes (Tregs) are neuroprotective, slowing disease progression. To address whether Tregs and FoxP3, a transcription factor required for Treg function, similarly influence progression rates ...

Rola limfocytów T regulatorowych w patogenezie wybranych chorób pęcherzowych

Przegląd Dermatologiczny, 2011
Regulatory T cells (Treg) are a phenotypically heterogeneous group ofcells, playing an important role in regulation of the immune response.To date, several subtypes of regulatory cells have been identified.
