NKp46- NK cells accumulated in the spleens of infected mice throughout 30 days of infection (Fig 10; representative FACs plots S6A–S6H Fig) and showed characteristic loss of CD49b as well as NKp46 expression, and gain of CD107a, FasL and TRAIL expression (S7 Fig, representative day 20 infected mouse). The gene discussed is FASLG; the disease is infection.
