Figure Lengend Snippet: Hypothetical model for inhibition of luteolysis by IFNT and chemokines. Although this model is not concerned with the effects of steroids or growth factors, IFNT, CCL2, CCL8, CCL16, CXCL10, and LIF may block TNF-stimulated-COX2 expression in bovine endometrial cells, leading to the reduction of TNF-induced PGF2α output from the cells. Furthermore, IFNT and CCL16 may stimulate anti-viral activity by up-regulating ISG15 and MX1 expression at the time of maternal recognition in cows. Red and blue arrows show stimulatory and inhibitory actions of each substance, respectively. IFNT may stimulate both CCL8 and CXCL10 production and inhibit CCL14 production from bovine endometrium. Effects of CCL11 on bovine endometrial function are still unclear, although its receptor (CCR3) is expressed in the endometrial epithelial cells.
Article Snippet: Cultured endometrial tissues were further incubated in the medium with recombinant proteins as follows: bovine CCL2 (RP0027B, Kingfisher Biotech., Inc. St. Paul, MN, USA), human CCL8 (281-CP, R&D Systems, Inc. Minneapolis, MN, USA), bovine CCL11 (RP0071B, Kingfisher Biotech.), human CCL14 (1578-HC, R&D Systems), human CCL16 (TP723266, OriGene Technologies, Inc., Rockville, MD, USA), bovine CXCL10 (RP0079B, Kingfisher Biotech.), bovine tumor necrosis factor-α (TNF; 2279-BT, R&D Systems), human leukemia inhibitory factor (LIF; TP723270, OriGene Technologies), bovine IFNT (1.1 × 10 5 U/mg, generated from HEK293 cells as described previously; Takahashi et al., 2017 [ ]) or supernatant derived from homogenized fetal trophoblast on day 18 of pregnancy (FMP).
