Generation and Immune Regulation of CD4+CD25-Foxp3) T Cells in Chronic Obstructive Pulmonary Disease

Open access

Abstract

The imbalance of CD4+Foxp3+ T cell subsets is reportedly involved in abnormal inflammatory immune responses in patients with chronic obstructive pulmonary disease (COPD). However, the possible role of CD4+CD25−Foxp3+ T cells in immune regulation in COPD remains to be investigated. In the current study, distribution and phenotypic characteristics of CD4+CD25−Foxp3+ T cells from peripheral blood were determined by flow cytometry; the origin, immune function and ultimate fate of CD4+CD25−Foxp3+ T cells were further explored in vitro. It was observed that circulating CD4+CD25−Foxp3+ T cells were significantly increased in stable COPD patients (SCOPD) and resembled central memory or effector memory T cells. Compared with peripheral CD4+CD25+Foxp3+ T cells, peripheral CD4+CD25−Foxp3+ T cells showed a lower expression of Foxp3, CTLA-4, HELIOS and TIGIT, but a higher expression of CD127 and KI-67, suggesting that CD4+CD25−Foxp3+ T cells lost the expression of Tregs-associated molecules following the reduction in CD25. Unexpectedly, our study found that transforming growth factor-β1 (TGFβ1) decreased CD25 expression and played a critical role in the generation of CD4+CD25−Foxp3+ T cells from CD4+CD25+Foxp3+ T cells. Phenotypic analysis further revealed that both inducible and peripheral CD4+CD25−Foxp3+ T cells exhibit the features of activated conventional T cells. Importantly, memory CD4+CD25−Foxp3+ T cells facilitated the proliferation and differentiation of naïve CD4+ T cells into Th17 cells in the presence of IL-1β, IL-6, IL-23 and TGFβ1. Finally, a fraction of CD4+CD25−Foxp3+ T cells, exhibiting instability and plasticity, were converted to Th17 cells when subjected to Th17 cell-polarizing condition. Taken together, we propose that TGFβ1 is responsible for the generation of CD4+CD25−Foxp3+ T cells, which functionally exert an auxiliary effect on Th17 cells generation and might perpetuate chronic inflammation in COPD.

    The Introduction and Discussion address the origins and stability of CD4+CD25−Foxp3+ cells in COPD and mention other autoimmune diseases, but do not address AQP4-specific ThEx cells or NMOSD. Searches for AQP4, NMOSD, and thymic Treg precursors found no passage establishing whether those cells derive from an unstable thymic Treg precursor. (LLM, conf=0.77)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
