Epithelial cells

renewal application builds on the discoveries made in the last funding cycle on effects of poultry dust on lung epithelial cells and monocytic cells, and lung inflammation in a mouse model. The data showed that poultry dust contains protease activity, induces robust inflammatory gene expression in lung epithelial and monocytic cells and activation of protease-activated receptors (PARs)-mediated cell signaling may be responsible for the elaboration of inflammatory gene expression. The data also…

Introduction There are many bioactive compounds that can be found around us. Bioactive compounds mostly can be found in both plants and animals. It is a compound that has an effect on a living organism, tissue or cell. It also can have an influence in our health. A few examples of bioactive compounds included flavonoids, caffeine, carotenoids, carnitine, choline, coenzyme Q, creatine, dithiolthiones, phytosterols, phytoestrogenss, glucosinolates, polyphenols, prebiotics, and taurine. Carotenoids…

body works Cell membrane: A cell membrane is a thin layer that forms a semi- permeable barrier around the outer surface of the cytoplasm of the cell and controls the movement of substances into and out of the cell. Nucleus: It contains DNA for making new cells and organisms and also controls the reaction in the cell. Chromosomes: Thread- like structures found in the nucleus of the cell which carry the genetic information Cytoplasm: The liquid gel which makes up a lot of the body of a cell and is…

more often Caucasian Americans. In the United States one in twenty among Caucasians are carriers, while in African Americans, Asians and Hispanics this rate is significantly lower. If there is CFTR dysfunction it will lead to an ionic imbalance of epithelial secretions in several organ systems, including the pancreas, gastrointestinal tract,…

Cells are very important because they are assumed to be the basics of life. There are two types of cells that exist: Prokaryotes and Eukaryotes. The interesting thing is that, even though the prokaryotes seem to be very different from the eukaryotes. For example, humans look very different from the bacteria, but they still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane…

drainage of bile in the liver. This progresses to biliary fibrosis and can be fatal if left untreated in the first two years after birth. Biliary atresia is the most typical source of end-stage liver disease. A previous study was carried out to identify a cell population expressing the PROMININ-1 gene. Within periportal fibrosis, the expansion of this population was studied and was located adjacent to ductular reactions. This study utilized a mouse model that was infected with the Rhesus…

a) Cystic fibrosis affects ion transport in what type of cells? (1 mark) Cystic fibrosis affects ion transport in epithelial cells b) The CFTR protein regulates the transport of a number of ions; name 2 of these ions. (2 marks) The CFTR protein regulates the transport of Cl- and Na+ c) Explain why a defective CFTR gene could cause Dan to produce very salty sweat. (5 marks) The normal function of the CFTR gene provides instructions for making a protein channel called the cystic fibrosis…

nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi apparatus A group of fluid-filled flattened membrane bound sacs located close to the nucleus. Vesicles are regularly seen at the sacs' edges. It is…

the past ten years’ medical advancements have escalated with stem cell research, therapies helping individuals with diseases and improving their overall health. Are you relying on a dialysis machine, ventilator, respirator, a left ventricular assist device, or waiting for a life-saving organ such as a liver? You may have been contemplating or waiting for an organ transplant, but you are unaware of all your options. Adult stem cell therapy should be an accepted ethical choice, it offers more…

selective permeability barrier that separates circulating blood from cerebrospinal fluid in the Central Nervous System (CNS). It is mainly formed by endothelial cells lining the brain microvessels. Pericytes envelope a part of the endothelium and have a common basal lamina. The “endfeet” of astrocytes surround the pericytes and endothelial cells and are connected to neurons through their numerous projections. The tight junctions…
