Journal Club Postsynaptic Neuronal Activity Promotes Retinal Axon Here, we established a paradigm in which the enhancement of neural activity in the distal optic pathway, where the postsynaptic visual target neurons reside, promotes rgc axon regeneration and target reinnervation and leads to the rescue of optomotor function.

Postsynaptic Neuronal Activity Promotes Regeneration Of Retinal Axons Here, we established a paradigm in which the enhancement of neural activity in the distal optic pathway, where the postsynaptic visual target neurons reside, promotes rgc axon regeneration and target reinnervation and leads to the rescue of optomotor function. Supraja’s presentation will provide insights into mechanisms that promote retinal ganglion cell (rgc) axon regeneration in vertebrates. her work will describe a distal optic tract injury model that can be used to investigate re connectivity of rgc axons to central targets in the brain. Here, we established a paradigm in which the enhancement of neural activity in the distal optic pathway, where the postsynaptic visual target neurons reside, promotes rgc axon. It is found that the light responsive g protein coupled receptor (gpcr) melanopsin could promote axonal regeneration after optic nerve crush by activating mtor, and it is shown that light, gq 11 signaling, and neuronal activity contribute to the mechanism that underlies this effect.

Supraja’s presentation provides insights into mechanisms that promote retinal ganglion cell (rgc) axon regeneration in vertebrates. Our findings indicate that pscl regen. treatment not only promotes axonal regeneration but also contributes to the partial recovery of the plr, even when administered during the chronic phase. Overall raw integrated density measured from f indicates “regenerating” axons; the same image is split into 200 µm bins (yellow rectangles 1 6) to obtain regeneration as a function of distance. This journal club demonstrates the effectiveness of an aav based gene therapy in rescuing vision and restoring normal retinal responses in a mouse model of kcnv2 retinopathy, a genetic form of irreversible blindness caused by mutations in the kv8.2 subunit of voltage gated potassium channels.
