Increased Spontaneous Apoptosis of Rat Primary Neurospheres In Vitro After Experimental Autoimmune Encephalomyelitis

Survival of neuronal progenitors (NPCs) is a critical determinant of the regenerative capacity of brain following cellular loss. Herein, we report for the first time, the increased spontaneous apoptosis of the first acute phase of Experimental Autoimmune Encephalomyelitis (EAE) derived neurospheres in vitro. Neuronal as well as oligodendroglial loss occurs during experimental autoimmune encephalomyelitis (EAE). This loss is replenished spontaneously by the concomitant increase in the NPC proliferation evidenced by the presence of thin myelin sheaths in the remodeled lesions. However, remyelination depends upon the survival of NPCs and their lineage specific differentiation. We observed significant increase ( P
