Background: Neuregulin-1/NRG1

Glial growth factor2, GGF-2, also known as cimaglermin alfa or NRG1 beta 3 (1), is a full-length splice variant of the Neuregulin-1 (NRG1) family gene. NRG1 is one of the four members  of the neuregulin family of genes (NRG1-4) encoding signaling proteins that facilitate cell–cell interactions in many tissues, including the nervous system and the heart (2). All family members share an EGF-like domain that interacts with the ErbB family of tyrosine kinase receptors. Through their displayed interaction with ERBB receptors, NRG1 isoforms induce the growth and differentiation of epithelial, neuronal, glial, and other types of cells. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells.Neuregulins are emerging as potential treatments for heart failure. GGF-2 was chosen as a development candidate with potentially long-lasting pharmacodynamic activity (4).
