Assessment of Sialic Acid Distribution in Mouse Epididymis
Previous studies have shown that epididymal epithelium and its secretions are critical for sperm maturation. These secretions contain many glycoconjugates with sialic acid terminal sugar. This terminal sugar by interveining in cellular interactions and masking surface receptors, has an important role in sperm maturation and protection. Moreover lectins have been employed as useful probes to det...
متن کاملThe terminal sialic acid of glycoconjugates on the surface of intestinal epithelial cells activates excystation of Cryptosporidium parvum.
The apicomplexan Cryptosporidium parvum reproduces in the intestinal epithelial cells of many mammalian species and is an agent of the important diarrheal disease cryptosporidiosis. Infection is transmitted fecal-orally by oocysts that pass through the stomach and excystation occurs in the intestine, releasing four invasive sporozoites. Some factors involved in inducing excystation have been id...
متن کاملDistribution of Specific Glycoconjugates in Early Mouse Embryonic Notochord and Paraxial Mesenchyme
It is well known that glycoconjugate components of the cell surface and extracellular matrix, play an essential role(s) in many developmental phenomena such as cell differentiation, migration, and cellular interactions. The purpose of this study was to investigate distribution of this macromolecules during differentiation of the notochord and paraxial mesoderm. Formalin fixed paraffin sections ...
متن کاملLectin Histochemistry Assessment of Seminiferous Epithelium Glycoconjugates in Mouse
Purpose: Plasma membrane glycoconjugates are important determinantsof differentiation and iteraction during spermtogenesis. Which entails miotic and meiosis proliferation, alternation in cell shape and so on. Hihg rates of them synthetized and present in acrosomes. With attention to such importancy, the present study has was designed to analyze glycoconjugates with special terminal sugar residu...
متن کاملSoluble uric acid induces inflammation via TLR4/NLRP3 pathway in intestinal epithelial cells
Objective(s): Hyperuricemia is a risk for cardiovascular and metabolic diseases, but the mechanism is ambiguous. Increased intestinal permeability is correlated with metabolic syndrome risk factors. Intestinal epithelial cells play a pivotal role in maintaining intestinal permeability. Uric acid is directly eliminated into intestinal lumen, however, the mechanism and e...
