Gestational diabetes mellitus (GDM) is linked to a greater risk of various maternal and fetal complications, including the possibility long-term metabolic issues in offspring. Our initial research suggests that Traditional Chinese Medicine formula, Shenling Guchang prescription (SLGP), may have an impact on gut microbiota. However, specific mechanisms through which it affects intestinal barrier inflammation GDM are still not fully understood. This study explored SLGP's GDM. Firstly, network pharmacology predicted key bioactive constituents targeting toll-like receptor 4 (TLR4)/nuclear factor-kappa B (NF-κB), guiding experimental design. Subsequently, pregnant female rats were induced with intraperitoneal streptozotocin injection then divided into control, model, metformin, SLGP treatment groups. Blood samples collected for ELISA analysis measure levels inflammatory markers, tissues examined histologically using hematoxylin-eosin (HE) staining, western blot was conducted evaluate TLR4 NF-κB expression. Relative control rats, model group animals exhibited significant increases markers (IL-1β, IL-6, TNF-α, TGF-β, CRP), as well enhanced p-NF-κB p65 expression, along histopathological changes. Treatment notably reduced protein expression colonic tissue leading decrease damage. Overall, found modulate TLR4/NF-κB pathway, resulting enhancements insulin resistance reduction responses thereby providing protection intestines. demonstrates potential therapeutic effectiveness addressing

ABSTRACT Advancing microbiome–gut–brain axis science requires systematic, rational and translational approaches to bridge the critical knowledge gaps currently preventing full exploitation of gut microbiome as a tractable therapeutic target for gastrointestinal, mental brain health. Current research is still marked by many open questions that undermine widespread application humans. For example, lack mechanistic understanding probiotic effects means it remains unclear why even apparently closely related strains exhibit different in vivo. live microbial psychobiotics, consensus on their adjunct treatments conventional neuromodulators, use unmedicated populations or at‐risk cohorts with sub‐clinical symptomatology warranted. This missing information both sides equation when treating central nervous system (CNS) conditions makes psychobiotic challenging, especially compared other pharmaceutical functional food approaches.
