As one of the most common metabolic diseases， type 2 diabetes (T2D) has become a public health concern with rising global prevalence. Corni fructus (CF)， a traditional Chinese herb utilized for centuries as homologous medicinal and food resources， has been widely used to treat glucose and lipid metabolism disorders. However， as a core active ingredient of CF， whether and how morroniside (MOR) improves T2D is still unclear. This study aimed to explore the pathways by which MOR ameliorates T2D in mice induced by high-fat diet (HFD) and low-dose streptozotocin (STZ) through 16S rRNA gene sequencing. We found that MOR treatment significantly ameliorated body weight loss， hyperglycemia， hyperlipidemia and insulin resistance in T2D mice. In addition， MOR remarkably improved inflammation- and oxidative stress-driven hepatic and pancreatic injuries in the model mice. Mechanistically， MOR rehabilitated the dysregulated diversity and constitution of the gut microbiota in T2D mice， with significant changes in relative abundance in genus such as Lactobacillus， Lachnospiraceae＿NK4A136＿Group， and Lachnospiraceae＿UCG-006 which are believed to be highly correlated with serum parameters and insulin resistance in mice with T2D. Therefore， we infer that MOR improves T2D at least partially by maintaining the host microbiota homeostasis， and MOR may be a promising candidate for T2D treatment.

Immunosuppressants currently approved for the treatment of autoimmune diseases and organ transplant rejection present diverse adverse effects that impair the life quality of patients. Therefore， the development of novel immunomodulators with high efficiency and low toxicity is essential. Ellagic acid (EA)， a natural polyphenol compound widely distributed in berries， is metabolically transformed by gut microbiome to exert systemic health benefits. Here， we identified that intraperitoneal administration of EA with no cytotoxicity， beyond its well-known oral metabolic fate， effectively decreased clinical severity and CNS inflammation/demyelination in experimental autoimmune encephalomyelitis (EAE)， a mouse model of an autoimmune disease multiple sclerosis (MS). Interestingly， intraperitoneal EA administration at incredibly low doses (0.1 mg/kg/d) is dose-sparing with fingolimod (FTY720)， the first FDA-approved oral drug for MS. In addition， intraperitoneal EA also ameliorated the brain damage in a neuromyelitis optica (NMO) model， and significantly prevented the immune rejection of allograft skin graft. Evidence from pharmacological studies combined with RNA-seq indicate that prototype EA functions by a mechanism that involves direct inhibition of casein kinase II (CKII) to suppress the expression of IL-17 and promote the expression of Cpt1a to regulate Th17 differentiation. In conclusion， our study demonstrates that the prototype EA entering the blood circulation acts as a novel therapeutic immunomodulator for the treatment of autoimmune diseases and transplant rejection through the CKⅡ-mediated JAK/STAT/Cpt1a signaling pathway.
