Researchers discover protective gene mutation in some HIV-infected patients

Mayo Clinic researchers have identified a naturally occurring “good guy” for patients infected with HIV. It is a helpful gene mutation that impairs the HIV virus’ cell-killing machinery, thus preserving immune system function. Moreover, Mayo’s experiments in mice suggest that the presence or absence of this mutation in the gene known as Vpr may play a central role in determining which HIV-infected patients develop full-blown, fatal AIDS.

Study Identifies Gene That Prevents Nerve Cell Death

Many neurological diseases occur when specific groups of neurons die because of nerve damage, toxins, inflammation, or other factors. A new study suggests that activity of a single gene can stop neurons from dying regardless of what triggers this process. The findings could lead to new ways of treating neurodegenerative diseases.
