Dectin-1 Fc Targeting of <i>Aspergillus fumigatus</i> Beta-Glucans Augments Innate Defense against Invasive Pulmonary Aspergillosis

Abstract

Invasive pulmonary aspergillosis (IPA) has significantly increased over the last decade. Here, a fusion protein consisting of the Dectin-1 extracellular domain linked to the Fc portion of murine immunoglobulin G1 augmented alveolar macrophage killing of Aspergillus fumigatus and shifted mortality associated with IPA via attenuation of A. fumigatus growth in the lung.
