Glial cells can protect or kill neurons Scientists have identified a double agent in the eye that, once triggered, can christian louboutin australia morph from neuron protector to neuron killer.The discovery has significant health implications since the neurons killed through this process results in vision loss and blindness. The findings, published in the journal proceedings of the national academy of sciences(Pnas), are collaboration between the Universit de Montreal, McGill University and the Montreal Neurological Institute in Canada and the Universit de Namur in Belgium.The researchers show how an unusual molecule, called prongf, activates glial cells that normally protect neurons in the retina and brain.Philip barker, a neuroscientist at the montreal neurological institute and a professor at the mcgill department of neurology and neurosurgery.Adriana di polo, a professor at the universit de montr al department of pathology and cell biology, compares the prongf molecule to a cell hijacker. “Before this study, we didn’t know what physiological role the prongf molecule played in the eye,”She says. “We now propose that, following brain damage or neurodegenerative diseases, prongf alters the glial cell network to change its function.Rather than protecting neurons, prongf makes the glial cells attack neurons. ” Scientists must now pay more attention to the damage prongf can trigger. “Once retinal neurons die, they are gone forever and the permanent loss of these cells causes blindness,”Warns dr.Di polo. Dr.Barker concurs. ralph lauren polo soldes “If we can block factors induced by prongf, we can protect neurons that would normally be lost.We think these findings may eventually translate into clinical benefits in diseases such as glaucoma. ” The study was supported by the canadian institutes of health research and the fonds de recherche en sant du qu bec.Bertrand, carlos r.Morales ralph lauren sale uk and philip a.Note:Materials may be edited for content and length.
