Abstract

The aim of this study was to determine the physiological significance of interleukin-1β (IL1B) and lipopolysaccharide-induced TNF factor (LITAF) in the fate of sperm in the oviduct of laying hens after artificial insemination (AI). Laying hens were inseminated with fresh semen, PBS or seminal...

Abstract

The immune response of hens during artificial insemination (AI) and the survival of spermatozoa in the oviduct were determined in a series of studies. It was shown that lymphocytes, CD4+ and CD8+ cells were increased in the utero-vaginal junction (UVJ) tissue of low-fertility hens after repeated AI ...

Abstract

The objective was to determine whether expression of estrogen receptor (ER) mRNA in the utero-vaginal junction (UVJ) of laying hens was altered after repeated artificial insemination (AI). Semi-quantitative RT-PCR was used to determine the expression of mRNA of the two types of receptor, ERα and...

Abstract

The goal of our present study was to observe whether the populations of antigen presenting cells (Ia+ cells) and T cell subsets (CD4+ and CD8+ T cells) change in the utero-vaginal junction (UVJ) of Rhode Island Red laying hens that showed dramatic declines in fertility after repeated artificial ...

Abstract

Our goal was to determine whether there is any correlation between the mRNA expressions of transforming growth factor β (TGFβ)-isoforms/their receptors and the fertility in chicken sperm stored in vitro for different times. The semen collected from White Leghorn roosters was divided into diluted...

Abstract

The goal of this study was to determine the mechanism by which the fertility is decreased by repeated artificial insemination (AI) in laying hens. The structures of sperm storage tubules (SST) and lymphocyte population in the uterovaginal junction (UVJ) of Rhode Island Red hens showing a declined...
