FSL-1

This small molecule agonist activates immune signaling via TLR2/6 and potentially TLR10, leading to NF-κB activation and the production of pro-inflammatory cytokines like IL-8 and TNF-α in vitro. It is used in research areas such as innate immunity, cancer immunology, and inflammation, where it can synergize with IFNγ to enhance CXCL10 release from cells.
