Summary: Immunotherapy is expected to be a promising treatment for ovarian cancer due to its immunogenicity. However, immunosuppression in the tumor microenvironment poses challenges. Studies have shown that the metabolism pathways of Tregs in the cancer environment may contribute to immunosuppression, and TLR8 can reverse the inhibitory function of Tregs. Activation of TLR8 signaling results in decreased glucose metabolism in Tregs and promotes proliferation of naive T cells in the ovarian cancer microenvironment.

Summary: The study found significant shifts in CD4(+) T cell subpopulations in multiple sclerosis (MS) patients, with reduced resting Treg, increased activated Treg, and increased effector CD4(+) cells. Additionally, some MS patients showed reduced CCR6(+)Th17-like Treg, which may contribute to the activity of MS.

Summary: The study reveals that a subset of CD14(+) monocytes can generate regulatory Foxp3(+) T-bet(+) T cells from umbilical cord blood, which suppress T-cell proliferation and ameliorate graft-versus-host disease. Additionally, adult peripheral blood monocytes are capable of inducing Foxp3(+) T cells, but their induction is inhibited by lymphoid cells from adult peripheral blood in neonates. This suggests a novel immunoregulatory role of monocytes in generating regulatory T cells with implications for both neonates and adults.

Summary: Solid organ transplantation (SOT) and vascularized composite allotransplantation (VCA) are the gold-standard treatments for end-stage organ failure and complex tissue defects. However, ischemia reperfusion injury (IRI) is a major factor that can negatively impact transplant outcomes. CD4+CD25+FOXP3+ regulatory T cells (Tregs) have immunomodulatory potential and can prevent and mitigate IRI. Increasing the number of Tregs and targeted delivery can improve the outcomes of SOT and VCA.

Summary: The immune response to an allograft can activate lymphocytes that cause rejection. The activation of T regulatory cells can reduce allograft rejection and induce immune tolerance. Activated T regulatory cells can be distinguished by various markers. A more detailed characterization of these cells may help reduce non-specific immunosuppression.

Summary: This study reevaluated the role of IL-2 and IL-15 in the development of regulatory T-lymphocytes (Treg) and found that IL-2 and IL-15 play important non-redundant quantitative and qualitative roles in intrathymic Treg development.

Summary: The study found that preoperative expansion of Tregs can mitigate the destabilization of atherosclerotic plaques induced by surgical stress. This suggests that therapeutic expansion of Tregs prior to major surgery may help prevent cardiovascular events associated with non-cardiac surgery.

Summary: In this study, the deficiency of CD1d-restricted iNKT cells was found to lead to the expansion of Foxp3(-)CD25(+)CD4(+) T cells in colitis. The MLN dendritic cells in DSS-treated Yeti/CD1d KO mice were shown to promote the differentiation of these cells. Furthermore, Foxp3(-)CD25(+)CD4(+) T cells were found to be pathogenic in DSS-treated Yeti/CD1d KO mice.

Summary: Transcription factors of the nuclear factor of activated T cell (NFAT) family play a crucial role in T cell function, particularly in the development and maintenance of regulatory T cells. This study found that NFAT factors are critical for the phenotype and survival of regulatory T cells in the thymus and peripheral lymphoid organs, but dispensable for their development.

Summary: The transcription factor FOXP3 is crucial for the development and function of CD4(+)FOXP3(+) regulatory T (Treg) cells. Alterations in the expression of FOXP3 isoforms are associated with inflammatory disease progression. This study investigates the effects of a specific FOXP3 mutation on Treg cell subsets. The findings suggest that the full-length FOXP3 isoform is important for maintaining Treg cell lineage stability but not essential for Treg cell activation.

Summary: The immune system not only fights infectious diseases, but also helps to combat noninfectious diseases while maintaining the balance between self and non-self discrimination. Understanding the cellular and molecular basis of immune regulation provides better insights into the immune pathology of diseases. One particular subset of CD4(+)T cells, positive for FoxP3 and negative for CD25, has been reported to have a range of functional activities in cancer and autoimmune diseases, but its exact role and functions are still under investigation.
