The effect of trans-10, cis-12 conjugated linoleic acid (t10c12-CLA) on the phagocytic capacity and oxidative burst activity (OBA) of canine peripheral blood phagocytes was examined. t10c12-CLA did not directly affect the phagocytic capacity and OBA of peripheral blood mononuclear cells (PBMC), monocytes or polymorphonuclear cells (PMN). However, the phagocytic capacity of PMN and monocytes was enhanced by the culture supernatant from t10c12-CLA-treated PBMC. This supernatant enhanced the latex bead-induced OBA of PMN and monocytes. t10c12-CLA also increased TNF-α production by PBMC. Recombinant canine (rc) TNF-α also increased the phagocytic capacity and OBA of PMN and monocytes. The ability of the culture supernatant from t10c12-CLA-treated PBMC to stimulate the phagocytic capacity and OBA of phagocytes was inhibited by anti-rcTNF-α pAb. These results suggest that t10c12-CLA has an immunoenhancing effect on the phagocytic capacity and OBA of phagocytes, and this effect may be mediated by TNF-α released from t10c12-CLA-treated PBMC.
