Transition to exhaustion: clues for cancer immunotherapy

Research on immune cells “exhausted” by chronic viral infection provides clues on how to refine cancer immunotherapy. The results were published Tuesday, Dec. 3 in Immunity. Scientists at Emory Vaccine Center, led by Rafi Ahmed, PhD, have learned about exhausted CD8 T cells, based on studying mice with chronic viral infections. In the presence of persistent virus or cancer, CD8 T cells lose much of their ability to fight disease, and display inhibitory checkpoint proteins Read more

Cecelia Bellcross, director of Emory’s genetics counseling program and an expert on breast cancer genetics counseling, reports that “in general, the clinical genetics community is jumping up and down, as are a lot of genetics lab directors and definitely patient advocacy groups.”

Myriad’s BRCA tests cost more than $3,000. Several competing firms announced that they would offer tests for the BRCA1 and 2 mutations at significantly lower prices.
