In Aim 2, we will examine whether the rate and pattern
of axon regeneration in these knockout mice are affected.
Paxillin phosphorylation counteracts proteoglycan - mediated inhibition
of axon regeneration.
The study, «Facilitation
of axon regeneration by enhancing mitochondrial transport and rescuing energy deficits,» which has been published in The Journal of Cell Biology, suggests potential new strategies to stimulate the regrowth of human neurons damaged by injury or disease.
Not exact matches
But exploring the role
of PPM - 2 in controlling DLK - 1 and
axon regeneration could be worthwhile — and could have implications in neurodegenerative diseases.»
The study describes how RPM - 1 regulates the activity
of a single protein known as DLK - 1, a protein that regulates neuron development and plays an essential role in
axon regeneration.
«This clearly refuted the assumption that getting rid
of scars would permit spontaneous
regeneration of injured
axons,» Sofroniew said.
Sheng and his research fellow Bing Zhou, the first author
of the study, initially found that when mature mouse
axons are severed, nearby mitochondria are damaged and become unable to provide sufficient ATP to support injured nerve
regeneration.
We are further exploring the molecular network in which the Tsc proteins function, and have found that modulation
of the growth - promoting mTOR pathway, which is regulated by TSC proteins, can promote
axon regeneration in the adult central nervous system.
During his doctoral and post-doctoral work under the mentorship
of Jeffrey Goldberg, MD, PhD, and Larry Benowitz, PhD, Dr. Trakhtenberg discovered (1) how Set - β and PP2A proteins regulate
axon growth; (2) the role
of serotonin receptor 2C in neurite growth and processing
of visual information; and (3) that inhibiting the transcription factor Klf9 acts synergistically with zinc chelation in stimulating
axon regeneration.
Our approach is innovative in that we propose to study a novel group
of bioinformatically - predicted factors, which we hypothesize cooperate in controlling RGC
axon growth and
regeneration.
They promote
regeneration of those
axons.
What his group found is that not only does that promote
axon regeneration all the way back down the nerve, but in fact those
axons go back to the right areas that they're supposed to get to in the brain — the right brain nuclei — and restore some measures
of visual function.
Summary: Poor
regeneration and reconnection
of retinal ganglion cell (RGC)
axons is a major obstacle for treating ocular trauma and diseases including glaucoma.
Searching the entire genome, a Yale research team has identified a gene that when eliminated can spur
regeneration of axons in nerve cells severed by spinal cord injury.
The Yale team found more than 580 different genes that may play a role in
regeneration of axons in nerve cells, something that rarely occurs in adult mammals but is
of vital interest to scientists hoping to repair injuries to the central nervous system.
The researchers also reported that eliminating one
of those genes, Rab27, led to
regeneration of axons in the optic nerve or spinal cord
of mice.
His laboratory at Stanford University School
of Medicine is developing novel stem cell and nanotherapeutics approaches for ocular repair, studying retinal ganglion cell development, survival and
axon regeneration in glaucoma, and investigating the cellular basis for the developmental loss
of axon growth ability.
