    <t>TLR4</t> inhibition supports zeolite-mediated reduction of LPS-induced NF-κB activation in THP-1 Dual cells. THP-1 Dual NF-κB reporter cells were pre-treated with the small-molecule TLR4 inhibitor TAK-242 (5 µM) for 1 h prior to stimulation with lipopolysaccharide (LPS) or combined clinoptilolite zeolite and LPS treatment conditions. DMSO (0.1%) was included as a vehicle control. Data are presented as mean ± SD. Statistical significance was determined using an unpaired Student’s t-test. ns, not significant.
