Of note, a recent study showed that Omeprazole encapsulated by applying nanostructured lipid carriers effectively target lung macrophages and inhibit multiple TLR pathways, including TLR3, TLR4, and TLR7/8 in a murine model of ALI, supplying a new therapy for clinical needs of ARDS [230]. Here, TLR7 is linked to acute respiratory distress syndrome.
