Did you know that the fetal immune system can protect from congenital infection before birth? -Proud to share our study identifying protective functions of #microglia, contrasting the harmful early influence of #monocytes and primitive macrophages to #zika virus infection.
Now online! Differential contributions of fetal mononuclear phagocytes to Zika virus neuroinvasion versus neuroprotection during congenital infection

Dengue is rising. In Nepal, studying >500 #dengue patients, we found that waning immunity to Japanese encephalitis virus (#JEV) was associated with worsened dengue severity, which has implications for #vaccine campaign planning. First au🙌: @smlhtr_ .

Excited to share our new #OpenAccess review: "Maternal IgE Influence on Fetal and Infant Health" led by Jozef. We discuss how maternal #IgE shapes fetal immunity and the shift to intrinsic early-life IgE production, with implications for #allergy onset. 👉
