Memory T cells' balance of granzyme K and granzyme B tracks with how healthily people age
Washington University's Maxim Artyomov and colleagues link memory T cells favoring granzyme K over granzyme B to healthier aging in a study in Immunity. The 17-year link to illness and death comes from UK Biobank adults whose cell levels were estimated from blood proteins, so the case for an aging blood test is still indirect.
