WebThe TLR4 and NF-κB mRNA transcription was increased at different time of LPS stimulation, and reached its peak on 6 h and then gradually decreased. Simultaneously, the TLR4 and NF-κB mRNA expression level was increased in a dose-dependent manner,and reached its peak when used at 4 μg/mL LPS and then decreased. TLR4 is a member of the toll-like receptor (TLR) family, which plays a fundamental role in pathogen recognition and activation of innate immunity. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity.
