WebEphrin-A5 has been shown to act as a repulsive cue for somatosensory thalamocortical (TC) axons expressing EphA receptors in the TC system ( Torii and Levitt, 2005 ). It seems to control the topography of TC projections within cortical areas ( Torii and Levitt, 2005 ). WebJul 25, 2012 · Ephrin-A5, a ligand for EphA4, is up-regulated in the reorganizing cortex after stroke ( 2, 3 ). These data indicate that ephrin-A5/EphA4 signaling after stroke may be in a position to limit the formation of new connections and recovery after stroke. WebThe second function of ephrins has been described as "reverse signaling", whereby the cytoplasmic domain becomes tyrosine phosphorylated, allowing interactions with other proteins that may activate signaling pathways in the ligand-expressing cells (5).
