IFNAR1 and infection: In contrast, minimal NET accumulation was detected in lesions of C57BL/6 mice at day 20 after infection (Fig. 9, k and l; and Fig. S5 g), despite the marked effects of IFNAR blockade on lesion Ly6G coverage and CD4+ T cell accumulation at this time point in C57BL/6 mice (Fig. 9, a–d).
