MBL2 and infection: MBL-knockout mice showed increased susceptibility to infection with a PR8 reassortant expressing the NA and NP segments and the highly glycosylated HA from the A(H3N2) strain A/Philippines/82 [111], but infection of MBL-deficient mice with A(H1N1)pdm09 or avian A(H9N2) strains, which are less heavily glycosylated, resulted in reduced severity and inflammation than in wild-type mice [117].
