Multifaceted Immunomodulatory Nanocomplexes Target Neutrophilic-ROS Inflammation in Acute Lung Injury.

ABSTRACT: The sepsis-induced acute lung injury (ALI) still represents one of the leading causes of death in critically ill patients, underscoring the need for novel therapies. Excessive activation of immune cells and damage of reactive oxygen species (ROS) are the main factors that exacerbate lung injury. Here, the multifaceted immunomodulatory nanocomplexes targeting the proinflammatory neutrophilic activation and ROS damage are established. The S100A8/9 inhibitor, ABR2575, is loaded in the nanocomplexes, which effectively blocks the neutrophils-S100A8/A9- toll-like receptors (TLRS)-Inflammasome signaling in ALI. Synergically, the SiH nanosheets are encapsulated together with ABR2575 into the core of poly(lactic-co-glycolic acid) (PLGA) nanosponges, to achieve sustainable hydrogen release for the a
