Microglial VPAC1R mediates a novel mechanism of neuroimmune-modulation of hippocampal precursor cells via IL-4 release.

Nunan R, Sivasathiaseelan H, Khan D, Zaben M, Gray W (2014) Microglial VPAC1R mediates a novel mechanism of neuroimmune-modulation of hippocampal precursor cells via IL-4 release. Glia 62:1313-1327. doi: 10.1002/glia.22682

Summary: Postnatal and adult learning and memory require hippocampal neurogenesis. Cognitive dysfunction is frequently accompanied by neuroinflammatory pathogenesis, but the pathways by which the immune system affects neurogenesis are unclear. In this work the authors depleted microglia from primary hippocampal cultures by incubating the cells with 100 μg/ml Mac-1-SAP rat (Cat. #IT-33) for 24 hours. The hippocampal cells were then washed and cultured for further experiments. It was found that neural stem/progenitor cells had reduced survival and proliferation in cultures treated with Mac-1-SAP. These data sketch out the framework of an immune-neuronal pathway important in the regulation of hippocampal neurogenesis.
