Immune regulation of ovarian development: programming by neonatal immune challenge
Neonatal immune challenge by administration of lipopolysaccharide (LPS) produces enduring alterations in the development and activity of neuroendocrine, immune and other physiological systems. We have recently reported that neonatal exposure to an immune challenge by administration of LPS results in altered reproductive development in the female Wistar rat. Specifically, LPS-treated animals exh...
متن کاملExosomes: Mediators of Immune Regulation
Extracellular Vesicles, including exosomes, are small membrane fragments released from many cell types, like Mesenchymal Stem Cells (MSCs). They were recognized as a mechanism of intercellular communication. They can transfer proteins, lipids and nucleic acids to other cells. Thus, they have many physiological (angiogenesis, coagulation and tissue repair, etc.) and pathological (e.g. in autoimm...
متن کاملP-64: Strategies to Optimize Reproductive Efficiencyby Regulation of Ovarian Function inyak (Poephagus Grunniens L.)
Background: To design a pre-Ovsynch hormonal strategy in yaks in order to increase the ovulatory response to the first GnRH injection of Ovsynch so that overall synchronization rate to Ovsynch could be improved. Materials and Methods: Non-lactating cyclic yak cows (n=33) were assigned to receive either no treatment before Ovsynch (control) or 0.375mg of PGF2(PreP) followed 2 d later by 10 g of ...
متن کاملASAS/ADSA Physiology: Nutritional Regulation of Ovarian Function/Ovarian Biology
A number of reproductive parameters are altered in lactating dairy cows including: twinning rate, expression of estrus, conception rate, pregnancy loss, and incidence of anovulation. We hypothesized that the high feed consumption associated with lactation has fundamentally altered reproductive physiology due to increased metabolism of steroids. We evaluated liver blood flow and steroid metaboli...
متن کامل//steroid Hormones and Regulation of Ovarian Function
A family of C29 4,4-dimethylsterol intermediates in the cholesterol biosynthetic pathway from lanosterol has been found to induce oocytes to resume meiosis.[248] One of these sterols, 4,4-dimethyl-5α-cholest-8,14,24-triene-3β-ol, was extracted from human follicular fluid and named follicular fluid meiosis–activating substance (FF-MAS). A related compound, 4,4-dimethyl-5α-cholest-8,24-diene-3β-o...
