Placental Extract and Exosomes Derived from Pregnant Mice Attenuate the Development of Experimental Autoimmune Encephalomyelitis
Abstract
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. Thereafter, the therapeutic effects of treatment were evaluated by measuring the clinical courses of the mice as well as determining the number of regulatory T (Treg) cells using flow cytometry, cytokine levels, and microRNA-326 expression via real-time PCR.
GA, PE, and exosomes reduced clinical severity, the extent of spinal cord demyelination, and the infiltration of inflammatory cells into the spinal cord. The frequency of CD4+CD25+FoxP3+ Treg cells increased after treatment of EAE mice with GA, PE, and exosomes. The mRNA expression of the inflammatory cytokines (interleukin-17 and interferon-gamma), as well as miR-326 expression, decreased significantly in the EAE mice after treatment with GA and exosomes.
PE and exosomes from pregnant mice are involved in the modulation of Treg/Th17 balance and provide a therapeutic approach for MS. Further clinical studies will hopefully confirm the safety and efficacy of such treatments in MS patients.
