Proposed model for the role of EphrinB2/EphB2 signaling in visceral hyperalgesia due to stress in early life. Activation of spinal EphrinB2/EphB2 signaling alters glia-neuron interactions, which contributes to visceral hyperalgesia arising from the stress of earlier maternal separation. Upon activation of EphrinB2/EphB2 signaling, spinal astrocytes and microglia interact with neurons via synapses, activated glia release inflammatory mediators that induce excessive excitatory neuronal activity involving the NMDA receptor.
