متن کاملBroiler chick thrombocyte response to lipopolysaccharide.
The effect of lipopolysaccharide (LPS) on the expression of proinflammatory cytokines, interleukin (IL)-1beta, IL-6, and IL-12 in broiler chick thrombocytes was investigated. At 4 wk of age, blood samples were collected, and isolated thrombocytes were incubated with LPS for 1 h. Ribonucleic acid was extracted from the cells to examine the expression of the proinflammatory cytokines using real-t...
