Phosphatidylglycerols (PG) is a selective inhibitor targeting the TLR4 accessory protein CD14/MD-2 complex, inhibiting LPS or virus (such as RSV)-mediated inflammatory signaling pathways through competitive binding. Phosphatidylglycerols directly bind to viral particles to block infection, inhibit COX-2 expression to reduce the release of inflammatory factors (IL-6, IL-8), and improve oxidative stress by regulating mitochondrial membrane phospholipid remodeling. Phosphatidylglycerols can be taken orally or by inhalation and can be used in the study of chronic inflammatory diseases (such as atherosclerosis) and respiratory viral infections (such as RSV) [2] .

Synonyms: LPS, from Serratia marcescens
Lipopolysaccharides, from S. marcescens (Serratia marcescens) are lipopolysaccharide endotoxins and TLR-4 activators derived from Serratia marcescens, classified as S-type LPS, which can activate pathogen-associated molecular patterns (PAMP) of the immune system and induce cellular secretion of migrasomes. Lipopolysaccharides, from S. marcescens exhibit a typical three-part structure: O-antigen (O-antigen), core oligosaccharide (core oligosaccharide), and lipid A (Lipid A). Lipopolysaccharides, from S. marcescens induce NF-κB activation in mouse cells via Toll-like receptor (TLR4)/MD-2. The lipopolysaccharides of S. marcescens can induce apoptosis in host immune cells, thereby suppressing the host's innate immunity [2].
It is recommended to prepare a solution with concentration 2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.
