Purinergic signaling in neural development

Abstract

Extracellular purine and pyrimidine compounds induce a multiplicity of cellular signal pathways that can induce multiple trophic functions. They interact with other low molecular weight messengers, growth factors, and extracellular matrix components. An increasing number of studies now provide evidence for a role of purinergic signaling in neural development, including progenitor cell proliferation, cell migration, neuronal and glial maturation and differentiation, and cell death and survival. This brief overview highlights recent developments supporting a contribution of purinergic signaling to embryonic and adult neurogenesis.
