| Abstract | Mitogenic responsiveness of intestinal intraepithelial lymphocytes (i-IEL) to concanavalin A (Con A), phytohemagglutinin P (PHA-P), and lipopolysaccharide (LPS) from Salmonella typhimurium were evaluated in various age groups of turkeys by a colorimetric blastogenic microassay. Comparisons were made between mitogenic responses of turkey i-IEL and peripheral blood lymphocytes (PBL). The results from this study demonstrated that i-IEL and PBL of turkeys responded to T-cell mitogens, Con A and PHA-P, in every age group examined. The LPS induced a significant mitogenic response in PBL but not in i-IEL of turkeys. The mitogenic responses of turkey i-IEL and PBL to the three mitogens examined were similar to mitogenic responses observed in an earlier study performed by using chicken i-IEL and PBL. The results indicated a difference in mitogenic response between different age groups. An increase was found in mitogenic response of i-IEL to both T-cell mitogens from 3 days of age to 1 wk of age, whereas mitogenic response of PBL to all three mitogens declined significantly from 1 day of age to 3 days of age. The highest mitogenic response of i-IEL to T-cell mitogens was observed at 1 wk of age. The highest mitogenic response of PBL to both T-cell mitogens was observed at 1 day of age and the highest PBL response to LPS was observed at 16 wk of age. The mitogenic response induced by PHA-P provided less variability between age groups than the mitogenic response induced by Con A. |
