Screaton and colleagues describe a protective Zika virus E-dimer-based subunit vaccine engineered to abrogate antibody-dependent enhancement of dengue infection.
NK cells recognize class I and stress-associated ligands. Altfeld and colleagues identify the NK cell receptor NKp44 as directly interacting with the class II HLA-DP in a partially peptide-dependent manner and with functional consequences for NK cell activity.
Dendritic cells (DCs) have been suggested to express a functional NLRP3 inflammasome. Gerlic and colleagues demonstrate, however, that bone marrow–derived DCs completely lack NLRP3 inflammasome activity and that the bulk of splenic DCs lack or have only minimal activity.
