| Description | RS 09 TFA is a TLR4 agonist and LPS peptide analogue that promotes NF-κB nuclear translocation and induces inflammatory cytokine secretion in RAW264.7 macrophages. It restores macrophage polarisation and inflammatory responses while disrupting the neuroprotective effects of ciliary proteins. |
| In vitro | In HEK-BLUETM-4 cells, RS 09 TFA (1-10 μg/mL, 24 hours) can stimulate TLR-4 and activate NF-κB[1]. In RAW264.7 cells, RS 09 TFA (5 μg/mL, 15 minutes-24 hours) binds to TLR-4 and induces NF-κB nuclear translocation as well as the secretion of inflammatory cytokines[1]. |
| In vivo | RS 09 TFA serves as an immune adjuvant, combined with the prostate cancer-specific antigen X-15 (conjugated to the carrier protein KLH) for immunization in BALB/c mice. Experimental results demonstrate that this compound can significantly elevate the concentration of X-15-specific antibodies in the mice [1]. |
