block reinfection.
They show that highly purified NS1 acts as a pathogen - associated molecular pattern (PAMP) that activates mouse macrophages and human peripheral
blood mononuclear
cells (PBMCs) in culture via TLR4, resulting in release of inflammatory cytokines — an effect that was
blocked by either a TLR4 antagonist or an anti-TLR4 antibody.
Specifically, they were able to determine that Wars2 plays an important role in supplying sufficient endothelial
cells, the building
blocks of
blood vessels, for angiogenesis.
Peter Carmeliet and his team demonstrated that endothelial
cells can be paralyzed by
