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.

In situ direct reprogramming technology can directly convert endogenous glial cells into functional neurons in vivo for central nervous system repair. Polypyrimidine tract-binding protein 1(PTB) knockdown has been shown to reprogram astrocytes to functional neurons in situ. In this study, we used AAV-PHP.e B-GFAP-sh PTB to knockdown PTB in a mouse model of ischemic stroke induced by endothelin-1, and investigated the effects of GFAP-sh PTB-mediated direct reprogramming to neurons. Our results showed that in the mouse model of ischemic stroke, PTB knockdown effectively reprogrammed GFAP-positive cells to neurons in ischemic foci, restored neural tissue structure, reduced inflammatory response, and improved behavioral function. These findings validate the effectiveness of in situ transdifferentiation of astrocytes, and suggest that the approach may be a promising strategy for stroke treatment.
