the respiratory tract contains numerous peptides secreted from special pulmonary epithelial cells whichare called endocrine cells. the function of neuroendocrine cells is modulated by amines. serotonin has strong vasomotor and bronchomotor effects in the airway mucosa. the objective of this study was to determine presence and distribution of serotonin-positive endocrine cells in respiratory tra...
Peroxiredoxin 1 (PRDX1) participates in tumor cell proliferation, apoptosis, migration, invasion, and the epithelial-to-mesenchymal transition (EMT). This study aimed to investigate effect of PRDX1 on EMT airway epithelial cells stimulated with lipopolysaccharide (LPS) transforming growth factor-beta (TGF-β1). overexpression significantly increased proliferation migration human bronchial (BEAS-...
introduction: this investigation was undertaken to examine chemical nature of glycoconjugate components on the surface of developing rat intestinal cells during gut histogenesis. materials and methods: rat embryos at days 10-12 of gestation was fixed in b4g and processed for lectinhistochemistry. 5m paraffin sections were incubated with 10-15 ?g/ml solution of hrp/lecti ns from arachis hypogaea...
Owing to this fact that most of the mortalities in cancers are as a result of metastasis, study on the involved pathways in metastasis including Epithelial to mesenchymal transition (EMT) would be so critical and important. Up to date, several extensive studies have been carried out to determine the correlation between EMT and cancer and their results have shown that the EMT plays pivotal role ...
Background: Nowadays, dendritic cells (DCs) have a special place in cancer treatment strategies and they have been used for tumor immunotherapy as they can induce immune response against tumor cells. Researchers have been trying to generate efficient dendritic cells in vitro therefore, this research was done to generate them for use in research and tumor immunotherapy. Methods: This study took...
هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
exposure to air pollutants is significantly associated with health risks ranging from bronchial reactivity to morbidity and mortality. however, the precise mechanisms are not always fully understood. the aim of this study was to investigate the effects of sulphur dioxide (so2) on cell viability and cytokine production of a549-human pulmonary epithelial cells. test atmospheres of so2 were genera...
Paracellular permeability across epithelial and endothelial cells is in large part regulated by apical intercellular junctions also referred to as the tight (TJs). These contribute spatial...
