Angiogenesis is induced in response to central nervous system (CNS) injury and inflammation. Toshihide Yamashita and colleagues show that in a mouse model of multiple sclerosis, new vessels form around inflammatory lesions and promote neuronal remodeling, rewiring of the corticospinal tract, and recovery of motor function in these mice. Prostacyclin is released from these vessels and promotes neuronal outgrowth by signaling through the IP receptor on neurons.
