Spatial regulation of axonal cAMP

Nature Chemical Biology volume 13, pages 348–349 (2017)Cite this article

Subjects

In early-stage developing neurons, the cAMP–PKA (protein kinase A) signaling pathway is strongly inhibited. This negative control is later removed, unleashing cAMP–PKA signaling, particularly in distal axonal parts, thus allowing for axonal growth.
