Researchers at Stanford College Faculty of Drugs say they’ve recognized a “biomarker” that signifies an individual’s susceptibility to flu viruses.

“We have been after this for about 4 years,” mentioned research senior creator Purvesh Khatri, an affiliate professor of drugs and of biomedical knowledge science.

“To our data, it is the primary biomarker that reveals susceptibility to influenza, throughout a number of strains,” Khatri mentioned in a college information launch.

A blood-based gene referred to as KLRD1 reveals the presence of a kind of immune cell believed essential for halting flu an infection within the early levels, the research authors mentioned.

The upper the degrees of this cell in somebody’s blood, the much less vulnerable they’re to the flu, the investigators mentioned.

Khatri famous that the hyperlink between KLRD1 ranges and influenza susceptibility is simply an affiliation, and would not show trigger and impact. The following step is to seek out the mechanism which may be at work.

“It is going to be essential to grasp the function of pure killer cells’ safety in order that we will probably leverage that in designing higher flu vaccines,” he mentioned. “Since we see that pure killer cells are protecting throughout completely different strains, possibly that may be a path to a common flu vaccine.”

The power to establish individuals at highest danger for flu an infection might be very helpful in sure conditions, the researchers mentioned.
