TNF-α was only significantly increased at 6 d.p.i (Fig 3C); IL-6 was significantly increased at 3 and 6 d.p.i (Fig 3E); IFN-γ and NOX2 were significantly increased at 3 and 6 d.p.i, (Fig 3G and 3I) and CD69 showed persistent elevation over the 6 days of infection (Fig 3K). Here, IL6 is linked to infection.
