Comparison of the mean levels of (A) TLR4+ MNCs in the spleen, (B) CD4+CD25+ Treg cells and (C) CD4+CD25+Foxp3+ Treg cells in the peripheral blood at different times, temperatures and with different stimulants. Data (%) are presented as the mean ± standard deviation. (A) For the comparison of the TLR4+ data among multiple times: F (3,108)=64.432, P<0.001; 1 h vs. 12 h, P<0.001; 1 h vs. 24 h, P<0.001; 12 h vs. 48 h, P<0.001; 24 h vs. 48 h, P<0.001. For the comparison of the TLR4+ data between temperatures and times: F (6,108)=29.595, P<0.001. For the comparison of the TLR4+ data between times and stimulants: F (6,108)=2.281, P=0.045. For the comparison of the TLR4+ data among temperatures, times and stimulants: F (12,228)=1.954, P=0.042. (B) For the comparison of the CD4+CD25+ Treg data among multiple times: F (3,108)=1.568, P=0.205. (C) For the comparison of the CD4+CD25+Foxp3+ Treg cell data among multiple times: F (3,108)=13.322, P<0.001; 1 h vs. 48 h, P<0.001; 12 h vs. 48 h, P<0.001; 24 h vs. 48 h, P<0.001. For the comparison of the CD4+CD25+Foxp3+ Treg cell data between temperatures and times: F (6,108)=4.434, P=0.001. For the comparison of the CD4+CD25+Foxp3+ Treg cell data between times and stimulants: F (6,108)=2.397, P=0.036). TLR, Toll-like receptor 4; CD, cluster of differentiation; Foxp3, Forkhead box P3; MNC, mononuclear cell; Treg, regulatory T; LPS, lipopolysaccharide; Con-A, concanavalin A.
