The Effect of Different Post-Hatching Periods on TLR4 and VEGF Expression Patterns in Broiler Ileum

Abstract

This study is aimed to evaluate the relationship between VEGF and TLR4 expression in the ileum during broiler post-hatching development. The material for the study was taken from the ileum tissue of 7-, 21-, and 42-day-old broilers. In tissue sections VEGF and TLR4 expression were demonstrated by Streptavidin-biotin complex immunohistochemistry method. Beginning on the 7th day after hatching, the number of stained cells and staining intensity in the epithelial cells lining the villus intestinalis increased in TLR4 immunostaining. On the 7th day following hatching, TLR4 protein expression was not seen in crypt epithelial cells. At day 21, crypt epithelial cells began to stain and gave a more intense immunoreaction at day 42. In VEGF-stained sections, the ileum villus epithelial cells, crypt, and smooth muscle tissue showed a brown intracytoplasmic response. The expression of the VEGF protein in the upper villus epithelial cells started to increase on the 7th day, and it stained intensely, especially on the 42nd day. In addition, it was observed that the staining intensity of the tunica muscularis layer was the same on the 7th and 21st days, and increased on the 42nd day. It was remarkable that goblet cells gave negative results in both immunostaining. In summary it seen that TLR4 and VEGF expression were found to be increase in this study from the 7th to the 42nd day following hatching. Thus, it was concluded that angiogenesis mechanisms and the development of innate and adaptive defense systems continue throughout the post-hatching period.
