During development, SGNs establish stereotyped innervation patterns with specific hair cell targets in the OC. Type I SGNs innervate inner hair cells to transmit sound signals, while type II SGNs (SGNIIs) innervate outer hair cells (OHCs) to detect acoustic trauma. Despite their essential functions in hearing, our understanding of the molecular mechanisms that mediate wiring of the auditory periphery is still fragmentary.<br \/>\nIt has been shown recently that guidance of SGNII peripheral projections is regulated by the Planar Cell Polarity (PCP) pathway. Intercellular PCP signaling mediates polarized cell behaviors within the plane of a tissue in a plethora of developmental processes. In the wild-type OC, SGNII afferents make a characteristic 90-degree turn toward the base of the cochlea and innervate multiple OHCs. In several PCP mutants, SGNII afferents turn randomly towards either the cochlear base or the apex. Although it has been shown that PCP proteins act in the cochlear epithelium to guide SGNII afferents, the underlying mechanisms are currently unknown. My research is focused on identifying downstream effectors of PCP signaling in the OC that directly mediate this unique innervation pattern. Specifically, I have identified the adhesion protein Nectin3 and the GTPase Rac1 as molecules of interest and am characterizing their respective roles in SGNII afferent guidance.<\/p>\n<\/div>\n<div>\n<div><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Our sense of hearing is critically dependent on the spiral ganglion neurons (SGNs), which connect the sound receptors in the organ of Corti (OC) to the cochlear nuclei of the hindbrain.
