Placental Extract and Exosomes Derived from Pregnant Mice Attenuate the Development of Experimental Autoimmune Encephalomyelitis.

Placental extract (PE) and exosomes from pregnant mice appear to have immunomodulatory and neuroprotective effects. In this study, we assessed the potential therapeutic effects of PE and exosomes obtained from pregnant mice in experimental autoimmune encephalomyelitis (EAE) mouse models. C57BL/6 mice, 8 to 12 weeks of age, were prepared and administered PE, exosomes, and glatiramer acetate (GA), as an FDA-approved treatment for multiple sclerosis (MS), after EAE induction.

Anti-Caspr-conjugated gold nanoparticles emergence as a novel approach in the treatment of EAE animal model.

Multiple sclerosis (MS) is a chronic autoimmune disorder of central nervous system which is increasing worldwide. Although immunosuppressive agents are used for the treatment of MS disease, nevertheless the lack of non-toxic and efficient therapeutic method is perceptible. Hence, this study aims to evaluate the effect of Contactin-associated protein (Caspr) antibody-, poly ethylene glycol (PEG)- and exosome combined gold nanoparticles (GNPs) in comparison to Glatiramer acetate as a selective treatment of MS disease in the experimental autoimmune encephalomyelitis (EAE) mouse model.
