Transplantation of Fas-deficient or wild-type neural stem/progenitor cells (NPCs) is equally efficient in treating experimental autoimmune encephalomyelitis (EAE).

Transplantation of Fas-deficient or wild-type neural stem/progenitor cells (NPCs) is equally efficient in treating experimental autoimmune encephalomyelitis (EAE). Am J Transl Res. 2014;6(2):119-28 Authors: Hackett C, Knight J, Mao-Draayer Y Abstract Studies have shown that neural stem/progenitor cell (NPC) transplantation is beneficial in experimental autoimmune encephalomyelitis (EAE), an established animal model of multiple sclerosis (MS). It is unclear whether NPCs have the ability to integrate into the host CNS to replace lost cells or if their main mechanism of action is via bystander immunomodulation. Understanding the mechanisms by which NPCs exert their beneficial effects as well as exploring methods to increase post-transplantation survival and differentiation is critical to advancing this treatment strategy. Using the EAE model and Fas-deficient (lpr) NPCs, we investigated the effects of altering the Fas system in NPC transplantation therapy. We show that transplantation of NPCs into EAE mice ameliorates clinical symptoms with greater efficacy than sham treatments regardless of cell type (wt or lpr). NPC transplantation via retro-orbital injections significantly decreased inflammatory infiltrates at the acute time point, with a similar trend at the chronic time point. Both wt and lpr NPCs injected into mice with EAE were able to home to sites of CNS inflammation in the periventricular brain and lumbar spinal cord. Both wt and lpr NPCs have the ...

CONCLUSIONS: NSC transplantation reversed the disease process by inducing an anti-inflammatory response and promoting myelination, neuroprotection, and neurogenesis in EAE disease animals. These promising results provide a basis for clinical studies to treat MS using NSCs derived from primitive MSCs.PMID:34503569 | DOI:10.1186/s13287-021-02563-8

AbstractNeuromyelitis optica spectrum disorders (NMOSD) are a group of autoimmune inflammatory conditions that primarily target the optic nerves, spinal cord, brainstem, and occasionally the cerebrum. NMOSD is characterized by recurrent attacks of visual, motor, and/or sensory dysfunction that often result in severe neurological deficits. In recent years, there has been a significant progress in relapse treatment and prevention but the residual disability per attack remains high. Although symptomatic and restorative research has been limited in NMOSD, some therapeutic approaches can be inferred from published case series a...
