Type 1 Diabetes Brazilian patients exhibit reduced frequency of recent thymic emigrants in regulatory CD4 +CD25 +Foxp3 +T cells. Immunol Lett 2024; 267:106857. [PMID: 38604551 DOI: 10.1016/j.imlet.2024.106857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 03/13/2024] [Accepted: 04/04/2024] [Indexed: 04/13/2024]
Abstract
To control immune responses, regulatory CD4+CD25+Foxp3+ T cells (Treg) maintain their wide and diverse repertoire through continuous arrival of recent thymic emigrants (RTE). However, during puberty, the activity of RTE starts to decline as a natural process of thymic involution, introducing consequences, not completely described, to the repertoire. Type 1 diabetes (T1D) patients show quantitative and qualitative impairments on the Treg cells. Our aim was to evaluate peripheral Treg and RTE cell frequencies, in T1D patients from two distinct age groups (young and adults) and verify if HLA phenotypes are concomitant associated. To this, blood samples from Brazilian twenty established T1D patients (12 young and 8 adults) and twenty-one healthy controls (11 young and 10 adults) were analyzed, by flow cytometry, to verify the percentages of CD4, Treg (CD4+CD25+Foxp3+) and the subsets of CD45RA+ (naive) and CD31+(RTE) within then. Furthermore, the HLA typing was also set. We observed that the young established T1D patients feature decreased frequencies in total Treg cells and naive RTE within Treg cells. Significant prevalence of HLA alleles, associated with risk, in T1D patients, was also identified. Performing a multivariate analysis, we confirmed that the cellular changes described offers significant variables that distinct T1D patients from the controls. Our data collectively highlight relevant aspects about homeostasis imbalances in the Treg cells of T1D patients, especially in young, and disease prognosis; that might contribute for future therapeutic strategies involving Treg cells manipulation.

Razazian M, Khosravi M, Bahiraii S, Uzan G, Shamdani S, Naserian S. Differences and similarities between mesenchymal stem cell and endothelial progenitor cell immunoregulatory properties against T cells. World J Stem Cells 2021; 13:971-984. [PMID: 34567420 PMCID: PMC8422932 DOI: 10.4252/wjsc.v13.i8.971] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/28/2021] [Accepted: 07/16/2021] [Indexed: 02/06/2023] Open
Abstract
Bone-marrow-derived mesenchymal stem cells and endothelial progenitor cells have some interesting biological properties that make them unique for cell therapy of degenerative and cardiovascular disorders. Although both cell populations have been already studied and used for their regenerative potentials, recently their special immunoregulatory features have brought much more attention. Mesenchymal stem cells and endothelial progenitor cells have both proangiogenic functions and have been shown to suppress the immune response, particularly T cell proliferation, activation, and cytokine production. This makes them suitable choices for allogeneic stem cell transplantation. Nevertheless, these two cells do not have equal immunoregulatory activities. Many elements including their extraction sources, age/passage, expression of different markers, secretion of bioactive mediators, and some others could change the efficiency of their immunosuppressive function. However, to our knowledge, no publication has yet compared mesenchymal stem cells and endothelial progenitor cells for their immunological interaction with T cells. This review aims to specifically compare the immunoregulatory effect of these two populations including their T cell suppression, deactivation, cytokine production, and regulatory T cells induction capacities. Moreover, it evaluates the implications of the tumor necrosis factor alpha-tumor necrosis factor receptor 2 axis as an emerging immune checkpoint signaling pathway controlling most of their immunological properties.

Regulatory T cells express Tumor Necrosis Factor Receptor 2 with the highest intensity among CD4 + T cells in the draining lymph nodes of breast cancer. Mol Immunol 2021; 137:52-56. [PMID: 34214829 DOI: 10.1016/j.molimm.2021.06.013] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 04/27/2021] [Accepted: 06/20/2021] [Indexed: 12/16/2022]
Abstract
Tumor Necrosis Factor Receptor 2 (TNFR2) is one of the receptors of TNF-α, which is expressed on various cell types. TNFR2 signaling has a balancing role between regulatory and effector functions of T cells. Herein, we investigated the expression of TNFR2 on regulatory T cells (Tregs) and non-Tregs in breast tumor-draining lymph nodes. Mononuclear cells were isolated from 16 axillary lymph nodes, and the expressions of TNFR2, Foxp3 and CD25 were assessed in CD4+ T cells by flow cytometry. Our results showed that the majority of TNFR2+CD4+ T cells were Foxp3-CD25-. However, the percentage of TNFR2+ cells was significantly higher in Foxp3+CD25+CD4+ Tregs compared to Foxp3-CD25-CD4+, Foxp3+CD25-CD4+, and Foxp3-CD25+CD4+ T cell subsets. Among these subsets, Foxp3+CD25+TNFR2+CD4+ T cells were found to have the highest intensity of TNFR2 expression. The intensity of Foxp3 expression in Foxp3+CD25+TNFR2+CD4+ Treg cells was significantly higher than in their TNFR2- counterpart. Collectively, we showed that most of TNFR2+CD4+ T lymphocytes were Foxp3-CD25-, while the majority of Foxp3+CD25+CD4+ Tregs were TNFR2+, and they expressed TNFR2 with the highest intensity. This report highlights the importance of TNFR2 expression on Tregs and paves the way for further investigation of the effects of TNF-α on the suppressive activity of Tregs in the tumor microenvironment.
