Chemotherapy is the main strategy for the treatment of lung cancer. However, sensitivity to chemotherapy, one of the main factors affecting the survival rate of patients with lung cancer, is extremely poor. Forkhead box P3 (Foxp3) is the key regulatory gene for the development and function of CD4+CD25+ regulatory T cells (Tregs). Increased levels ...
It is well established that CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs) play a crucial role in the course of different infectious diseases. However, contradictory results have been published regarding to malaria infection. In this study, we report that specific ablation of Foxp3(+) Tregs in Plasmodium yoelii-infected DEREG-BALB/c mice leads to an increase in T cell activation accompanied b...
Objective(s): Here we investigated the regulation of Th17 and Treg cells in orthodontic tooth movement during periodontal inflammation.Materials and Methods: Fifty-six SD rats were divided into a control (24 rats) and a tooth movement group during the recovery stage of periodontitis (RM group, 32 rats). Periodontitis was established by s...
Alteration of T helper cell subsets in the optic nerve of experimental autoimmune encephalomyelitis.
The objective of this study was to detect interleukin-17 (IL-17), interferon-gamma (IFN-gamma), interleukin-4 (IL-4) and forkhead/winged helix transcription factor p3 (Foxp3) protein and gene expression of the optic nerve and to further explore the role of T helper cell subsets such as Th1, Th2, Th17 and Treg in the pathogenesis of optic neuritis in experimental autoimmune encephalomyelitis (EA...
CD4(+)CD25(+) regulatory T cell-mediated immunosuppression is one of the crucial mechanisms that tumor cells use to evade the immune system. The forkhead box P3 (FoxP3) gene regulates regulatory T-cell development and function and may modulate the susceptibility to non-small cell lung cancer (NSCLC). Because a single nucleotide polymorphism (SNP) within the FoxP3 gene (rs3761548 in the promoter...
Stats (signal transducers and activators of transcription) regulate multiple aspects of T-cell fate. T regulatory (Treg) cells are a critical subset that limits immune responses, but the relative importance of Stat5a/b versus Stat3 for Treg cell development has been contentious. We observed that peripheral CD25(+)CD4(+) T cells were reduced in Stat5(DeltaN) mice; however, the levels of Foxp3, a...
Gene transfer of a factor VIII (FVIII) plasmid into hemophilia A (HemA) mice achieved supraphysiologic FVIII expression, but triggered production of high-titer FVIII-specific antibodies and loss of functional FVIII activity. To test whether FVIII-specific regulatory T cells (Tregs) can modulate immune responses against FVIII, we developed a HemA mouse model in which all T cells overexpressed Fo...
