چکیده انگلیسی
The main innate cellular immune responses of gilthead seabream (Sparus auratus L.) leucocytes were evaluated after in vitro incubation with human lactoferrin (Lf). Isolated head-kidney leucocytes were incubated with 0 (control) to 1 mg mlâ1 Lf-supplemented culture medium for 30, 120, 240 or 360 min and assayed for viability, peroxidase content, and respiratory burst, phagocytic and cytotoxic activities. Only respiratory burst activity was found to increase when using the highest Lf concentration (1 mg mlâ1) and long incubation times (more than 120 min). Seabream were fed Lf-supplemented diets (0, control, 50, 100 or 200 mg kgâ1 diet). After 1 or 2 weeks of administration the leucocyte peroxidase content, respiratory burst, phagocytic and cytotoxic activities as a measure of cellular immune responses, as well as serum peroxidase and complement activity as a measure of humoral immune responses were evaluated. The results showed that Lf feeding at 100 mg kgâ1 diet for 1 week enhanced the cellular innate immune responses although only the cytotoxic activity did so significantly. The humoral immune response was not influenced by Lf feeding. In conclusion, Lf seems to affect innate immune cellular activity, mainly respiratory burst and natural cytotoxic activity. The possible use of Lf as an immunostimulant for farmed gilthead seabream is discussed.
