PTEN-deficient Tregs rapidly proliferate in response to IL-2 stimulation alone, with restoration of PTEN expression sufficient to reverse this phenotype
This disruption is consistently characterized by a decrease in microbial alpha diversity and significant shifts in beta diversity, patterns observed across numerous studies and particularly exacerbated in aged hosts ( Akkermansia , Lactobacillus , Clostridiaceae , and Muribaculaceae , and a concomitant increase in pro-inflammatory taxa including Prevotellaceae , Proteobacteria , and pathobionts like Mucispirillum schaedleri ( P.g administration also induces significant fungal dysbiosis (mycobiome), enriching pathogenic species such as Pyricularia pennisetigena , Alternaria alternata , and Candida glabrata , which correlate with alterations in host metabolic pathways, especially tryptophan metabolism ( P.g and its metabolites directly and indirectly compromise gut integrity by downregulating the expression of tight junction proteins (ZO-1, Occludin, Claudins) and mucins (MUC2), leading to increased intestinal permeability (Tsuzuno et al., 2021
Studies have shown that the manganese superoxide dismutase (MnSOD) mimetic MnTBAP effectively prevented mitochondrial damage by reducing DNMT1 binding to the MMP-9 promoter (Kowluru and Shan, 2017), suggesting that targeting DNA methylation to inhibit MMP-9 could suppress oxidative stress and serve as a promising therapeutic strategy for diabetic retinopathy
