Researchers from the University of Washington and Fred Hutchinson Cancer Research published a study in Nature based to demonstrate the identification of immunological role of a class of cytotoxic T cells in genital herpes. They identified the cells to be CDT cells that primarily exist in the skin of genital region and mucosa. These cells inhibit the recurrence of genital herpes. Since they suppress the replication of the HSV-2 virus, at the site of recurrence they also prevent symptoms in the patient.
Genital herpes is a sexually transmitted disease affecting more than 24 million people in the US
