BACKGROUND Regulatory T cells (Tregs) play a role in the suppression of inflammation in autoimmune diseases, and lymphocyte activation gene 3 (LAG3) was reported as a marker of interleukin (IL)-10-producing Tregs. We aimed to clarify the function of human IL-10-producing CD4+CD25-LAG3+ T cells (LAG3+ Tregs) and their association with rheumatoid arthritis (RA). METHODS LAG3+ Tregs of human per...

CD4+ CD25+ Foxp3+ regulatory T cells (Tregs) are highly sensitive to IL-2, one of the many cytokines produced during immune responses, for their development, survival and functions. Although effects IL-2 administration on Tregs in vivo well characterized, elicited by an response have not been elucidated. Hence, this study, Treg behaviour IL-2–producing responses was explored using vitro murine ...

Chimeric antigen receptors (CARs) are a breakthrough in genetic engineering that have revolutionized the field of adoptive cellular therapy (ACT). Cells expressing these rerouted to predefined target by inclusion an antigen-specific binding region within synthetic CAR construct. The advantage cells with programmed specificity has been demonstrated clinically oncology, and it is clear such great...

Fibroblast-like synoviocytes (FLS) colocalize with leukocyte infiltrates in rheumatoid synovia. Proinflammatory leukocytes are known to amplify inflammation by signaling to FLS, but crosstalk between FLS and regulatory T cells (Tregs) remains uncharacterized. To address this possibility, we cocultured FLS lines derived from arthritic mice with Tregs. FLS that expressed the ligand for glucocorti...

BACKGROUND Impaired regulatory T cell (Treg) function is thought to contribute to ongoing inflammatory responses in sarcoidosis, but underlying mechanisms remain unclear. Moreover, it is not known if increased apoptotic susceptibility of Tregs may contribute to an impaired immunosuppressive function in sarcoidosis. Therefore, the aim of this study is to analyze proportions, phenotype, survival,...

Latency-associated peptide (LAP) - expressing regulatory T cells (Tregs) are important for immunological self-tolerance and immune homeostasis. In order to investigate the role of LAP in human CD4⁺Foxp3⁺ Tregs, we designed a cross-sectional study that involved 42 colorectal cancer (CRC) patients. The phenotypes, cytokine-release patterns, and suppressive ability of Tregs isolated from periphera...

FOXP3(+) regulatory T cells (Tregs) are critical regulators of self-tolerance and immune homeostasis. In mice and humans, two subsets of FOXP3(+) Tregs have been defined based on their differential expression of Helios, a transcription factor of the Ikaros family. Whereas the origin, specificity, and differential function of the two subsets are as yet a source of controversy, their characteriza...

A significant enrichment of CD4(+)Foxp3(+) T cells (regulatory T cells, Treg) is frequently observed in murine and human carcinomas. As Tregs can limit effective antitumor immune responses, thereby promoting tumor progression, it is important that the mechanisms underpinning intratumoral accumulation of Tregs are identified. Because of evidence gathered mostly in vitro, the conversion of conven...

Regulatory T cells (Tregs) suppress excessive immune responses and are potential therapeutic targets in autoimmune disease and organ transplantation rejection. However, their role in renal ischemia-reperfusion injury (IRI) is unclear. Levels of Tregs and expression of CXCR3 in Tregs were analyzed to investigate their function in the early phase of renal IRI. Mice were randomly divided into Sham...

Adoptive immunotherapy with regulatory T cells (Tregs) is a promising treatment for allograft rejection and graft-versus-host disease (GVHD). Emerging data indicate that, compared with polyclonal Tregs, disease-relevant antigen-specific Tregs may have numerous advantages, such as a need for fewer cells and reduced risk of nonspecific immune suppression. Current methods to generate alloantigen-s...
