TLR4 and hydrops fetalis: Moreover, HF feeding induced significant hepatic inflammation, as shown by the increase in hepatic mRNA expression of Tnf-α, Il-1ß, Il-6, and Tlr4. These increments in mRNA expression were partially prevented by both oils in the of Il-1ß and totally prevented for Tnf-α, Il-6, and Tlr4.
