New compelling evidence indicates that the pentose phosphate pathway (PPP) profoundly regulate lineage development in the immune system that are influenced by genetic and environmental factors during metabolic stress underlying the development of autoimmunity. The PPP provides two unique metabolites, ribose 5-phosphate for nucleotide biosynthesis in support of cell proliferation and NADPH for protection against oxidative stress. The PPP operates two separate branches, oxidative (OxPPP) and non-oxidative (NOxPPP). While the OxPPP functions in all organisms, the NOxPPP reflects adaptation to niche-specific metabolic requirements. The OxPPP primarily depends on glucose 6-phosphate dehydrogenase (G6PD), whereas transaldolase (TAL) controls the rate and directionality of metabolic flux though the NOxPPP. G6PD is essential for normal development but its partial deficiency protects from malaria. Although men and mice lacking TAL develop normally, they exhibit liver cirrhosis progressing to hepatocellular carcinoma. Mechanistic target of rapamycin-dependent loss of paraoxonase 1 drives autoimmunity and cirrhosis in TAL deficiency, while hepatocarcinogenesis hinges on polyol pathway activation via aldose reductase (AR). Accumulated polyols, such as erythritol, xylitol, and sorbitol, which are commonly used as non-caloric sweeteners, may act as pro-inflammatory oncometabolites under metabolic stress, such as TAL deficiency. The TAL/AR axis is identified as a checkpoint of pathogenesis and target for treatment of metabolic stress-driven systemic autoimmunity with relevance for inflammatory liver, renal and cardiovascular disorders, diabetes, carcinogenesis, and aging.</div></div>","PeriodicalId":8664,"journal":{"name":"Autoimmunity reviews","volume":"24 5","pages":"Article 103781"},"PeriodicalIF":9.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143514459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The progression of RA can be delineated into four distinct phases: initially, the influence of genetic and environmental risk factors; followed by the emergence of systemic autoimmunity; subsequently, an asymptomatic inflammatory phase; and ultimately, the manifestation of clinical arthritis. Recently, the role of mucosal immunity in RA has gained significant attention in research. Evidence from published studies suggests that mucosal immunity not only influences the onset of RA but also plays a crucial role in its progression. Scholars have begun to unravel the intricate links between RA and the mucosal barriers of the gastrointestinal tract, respiratory system, and oral cavity. Specifically, shifts in the mucosal microbiota, dysfunction of mucosal barriers, and the abnormal activation of mucosal immune tissues are all implicated in the pathogenesis of RA.Despite this growing body of knowledge, a comprehensive review of the abnormal mucosal immunity in RA and its therapeutic implications is yet to be conducted.
