Researchers find new mechanism for neurodegeneration

A research team led by Jackson Laboratory Professor and Howard Hughes Investigator Susan Ackerman, Ph.D., have pinpointed a surprising mechanism behind neurodegeneration in mice, one that involves a defect in a key component ...

Window of opportunity against HIV comes from 'fitness bottleneck'

New research on HIV transmission shows that viral fitness is an important basis of a "genetic bottleneck" imposed every time a new person is infected. The findings define a window of opportunity for drugs or vaccines to prevent ...

Immunology

Protein identified as important trigger of antiviral response

Cells have to protect themselves: against damage in their genetic material for one thing, but also against attack from the outside, by viruses for example. They do this by using different mechanisms: special proteins search ...

Genetics

Refining the language for chromosomes

When talking about genetic abnormalities at the DNA level that occur when chromosomes swap, delete or add parts, there is an evolving communication gap both in the science and medical worlds, leading to inconsistencies in ...

Genetic signature reveals new way to classify gum disease

Researchers at Columbia University Medical Center (CUMC) have devised a new system for classifying periodontal disease based on the genetic signature of affected tissue, rather than on clinical signs and symptoms. The new ...

Trick that aids viral infection is identified

Scientists have identified a way some viruses protect themselves from the immune system's efforts to stop infections, a finding that may make new approaches to treating viral infections possible.
