Note: FSL-1 stimulation induces a MyD88-dependent signaling cascade leading to the activation of NF-κB and the production of proinflammatory cytokines. FSL-1 exhibits a higher stimulatory activity than MALP-2 when tested for its ability to induce the production of TNF-α in macrophages and NF-κB in TLR2/TLR6 transfected HEK293 cells. Depending on the sensitivity of the in vitro assay, the recommended working concentration for specific stimulation of innate immunity via TLR2/TLR6 heterodimers is 10-100nM. FSL-1 is water soluble in contrast to MALP2. |
