Subject:
chick embryos; chickens; embryogenesis; epithelial cells; gene expression; genes; heterophils; immune response; in situ hybridization; innate immunity; messenger RNA; nutrient uptake; peptides; yolk sac
Abstract:
... The chicken yolk sac (YS) plays an important role in nutrient absorption and immune function for the developing embryo. The avian β-defensins (AvBD) are cationic peptides that are important members of the innate immune system. The objective of this study was to profile AvBD mRNA expression patterns and distribution of cells expressing AvBD mRNA in the chicken YS. Expression of AvBD1, 2, 7, and 10 ...

Subject:
Monodelphis domestica; T-lymphocytes; adaptive immunity; animal tissues; epithelial cells; evolution; immunohistochemistry; lactation; mammary glands; milk; neonates; nutritional support; opossums; passive immunity; weaning
Abstract:
... Milk provides mammalian neonates with nutritional support and passive immunity. This is particularly true in marsupials where young are born highly altricial and lacking many components of a fully functional adaptive immune system. Here we investigated the T cell populations in the mammaries of a lactating marsupial, the gray short-tailed opossum Monodelphis domestica. Immunohistochemistry confirm ...

Abstract:
... TLR7 subfamily members are important pattern recognition receptors participating in the recognition of pathogen-associated molecular patterns. In this study, we successfully identified 3 members of TLR7 subfamily from the spiny eel Mastacembelus armatus (MaTLR7, MaTLR8 and MaTLR9). The amino acid sequence identities of MaTLR7 and MaTLR8 with Monopterus albus TLR7 were 87.2% and 76.5%, respectively ...

Abstract:
... Tyramine (TA), a neuroactive chemical, plays various important physiological roles in insects by activating distinct G-protein-coupled receptors (GPCRs). In this study, we investigated the effects of by pharmacological injection of TA on immune resistance regulation and its signal pathway in white shrimp Litopenaeus vannamei. Results showed significant increases in the total haemocyte count (THC), ...

Abstract:
... Caveolin-1 is the main structural and functional component of caveolin, and it is involved in the regulation of cholesterol transport, endocytosis, and signal transduction. Moreover, changes in caveolin-1 play an important role in tumorigenesis and inflammatory processes. Previous studies have demonstrated that human caveolin-1 is mainly located in the cell membrane and exhibits cell type- and sta ...
