Washington:
Researchers have found a way to help the brain replace damaged
nerve cells or neurons, a study reveals.
Myelin forms a protective sheath around the axons or fibres of our
neurons so that they can send signals quickly and efficiently.
But myelin and the specialized cells called oligodendrocytes that
make it, become damaged in disorders like multiple sclerosis (MS),
leaving neurons without their myelin sheaths, the Journal of
Neuroscience reported.
Consequently, the affected neurons can no longer communicate
correctly and are prone to damage. Researchers from the California
Institute of Technology (Caltech) now believe they have found a
way to help the brain replace damaged oligodendrocytes and myelin,
said a university statement.
"We've developed a gene therapy to stimulate production of new
oligodendrocytes from stem and progenitor cells -- both of which
can become more specialized cell types -- that are resident in the
adult central nervous system," said Benjamin Deverman, from
Caltech, who led the study.
