Absence of Circulating Natural Killer and Primed CD8+Cells in Life‐Threatening Varicella

Abstract excerpt

Five pediatric patients with no history of immunodeficiency had a life-threatening course of varicella. Strikingly, natural killer (NK) cells were absent from the circulation in all children, and, despite active viral infection, up to 98% of the CD8(+) cells were naive. Primary immunodeficiencies were excluded--NK cells and primed CD8(+) cells reappeared in the circulation, granzymes were detectable in plasma...
