TLR2 and TLR4 deficiencies affect the secretion of cytokines in S.uberis infection. (A,B) The protein expressions of TNF-α, IL-1β and IL-6 were determined by ELISA in mammary gland of WTB6, WTB10, TLR2^−/− and TLR4^−/− mice with or without S. uberis. A is for the protein expressions for TLR2^−/− group and B is for the TLR4^−/− group. Experiments were repeated three times and all data were presented as the means ± SEM (n = 6). * (p < 0.05) = significantly different between the indicated groups.
