New Danish-led interrogation suggests that signs of encephalon aging tin endure postponed inwards mice if placed on a high-fat diet. In the long term, this opens the possibility of handling of children suffering from premature aging in addition to patients amongst Alzheimer's in addition to Parkinson's disease. The interrogation projection is headed past times the Center for Healthy Aging, University of Copenhagen in addition to the National Institute of Health.
When nosotros larn older, defects start out to prepare inwards our nervous system, our encephalon loses roughly of its intellectual capacity, in addition to the run a peril of developing diseases such every bit Parkinson's in addition to Alzheimer's increases. Alzheimer's illness is currently the fastest-growing age-related disease.
Throughout our lives, it is of import that our cells -- to the extent possible -- locomote on our deoxyribonucleic acid undamaged, and, therefore, the cells convey a organization that repairs the impairment that occurs all the time. Humans historic menstruum when the repair organization ceases to function. In diseases such every bit Alzheimer's, the researchers likewise come across impairment to the DNA
A novel interrogation projection headed past times the Center for Healthy Aging, University of Copenhagen in addition to the National Institute of Health has studied mice having a defect inwards their deoxyribonucleic acid repair system. In humans, this defect causes the disorder Cockayne syndrome, where patients prematurely historic menstruum every bit children in addition to croak at an historic menstruum of 10-12 years. The written report shows that placing a mouse model of Cockayne syndrome on a high-fat diet volition postpone aging processes such every bit impaired hearing in addition to weight loss.
Fat putting a destination to premature aging
"The written report is skillful tidings for children amongst Cockayne syndrome, because nosotros arrive at non currently convey an effective treatment. Our written report suggests that a high-fat diet tin postpone aging processes. H5N1 diet high inwards obese likewise seems to postpone the aging of the brain. The findings thence potentially imply that patients amongst Alzheimer's in addition to Parkinson's illness inwards the long term may arrive at goodness from the novel knowledge," says Professor Vilhelm Bohr from the Center for Healthy Aging, University of Copenhagen in addition to the National Institute of Health, who has headed the study.
Our encephalon has a constant necessitate for fuel inwards the shape of either carbohydrate or so-called ketones. Ketones are the brain's fuel reserve, and, inwards particular, play an of import role inwards periods of depression blood carbohydrate levels, e.g. if you lot are fasting. This is because the trunk breaks downward obese if it needs sugar, in addition to during this procedure it produces ketones. The researchers come across a detail positive outcome when the mice are given the so-called medium chain obese acids -- e.g. from kokosnoot oil.
Brain cells necessitate extra fuel
"In cells from children amongst Cockayne syndrome, nosotros convey previously demonstrated that aging is a outcome of the jail cellular telephone repair machinery existence constantly active. It eats into the resources in addition to causes the jail cellular telephone to historic menstruum real quickly. We thence promise that a diet amongst a high content of kokosnoot crude or similar fats volition convey a beneficial effect, because the encephalon cells are given extra fuel in addition to thus the forcefulness to repair the damage," says postdoc Morten Scheibye-Knudsen from the National Institute of Health.
The written report has only been published inwards the scientific journal Cell Metabolism.
