Removing Old Cells
November 4, 2011 by staff
Body cells keep dividing forever, but to reach a state known as cellular senescence, which is no longer divided but the release of substances that damage surrounding cells, scientists at the Mayo Clinic said.
The immune system normally has cells zombies, but with age it loses its ability to do so, they said.
“By targeting these cells and what they produce, one day you may be able to break the link between the mechanisms of aging and predisposition to diseases such as heart disease, stroke, cancer and dementia,” Dr. James Kirkland, a co-author of the study, said in a statement.
The researchers say that the removal of senescent cells could delay the onset of cataracts, a gradual loss of muscle tissue and other problems associated with aging, CBS News reported Thursday.
“Therapeutic interventions to get rid of senescent cells or block their effects may represent a way to make us feel more vital, healthy, and allow us to remain independent for much longer,” Dr. Jan van Deursen, a study co-author , said in a statement.
Research suggests it may be possible to develop drugs that kill senescent cells in humans or improve the ability of the aging immune system to dispose of them, the researchers said.
