active retinoid by slightly upregulating mRNA levels of TLR2, TLR4 and CD14, while 13cis -RA and alltransRA were practically inactive. Retinoids did not affect mRNA levels of IL-1 , IL-1 and IL-8 mRNA and their release. However, IL-6 mRNA levels and release were significantly reduced under treatment with 13cis -RA and alltrans -RA being more potent than retinol, indicating a selective, TLR-inde...
