Regulation of Tight Junctions in Upper Airway Epithelium
The mucosal barrier of the upper respiratory tract including the nasal cavity, which is the first site of exposure to inhaled antigens, plays an important role in host defense in terms of innate immunity and is regulated in large part by tight junctions of epithelial cells. Tight junction molecules are expressed in both M cells and dendritic cells as well as epithelial cells of upper airway. Va...
متن کاملTight Junctions
Epithelial cells cover the body (e.g. skin), cavities (e.g. stomach, uterus, bladder) and ducts (e.g. renal tubules, intestine) of multicellular organisms, and thus constitute the frontier between the individual and the external milieu. In areas that withstand strong mechanical or chemical stress (e.g. skin, esophagus, cornea, vagina) epithelia are stratified, whereas in the rest of the body, t...

part of my lab in that direction with work on human embryonic stem cells which, as we have come to learn, show aberrant epigenetic regulation. There is a lot to learn from this much needed human model. What do you enjoy most about science? The challenge, the discovery, and the people. In this profession, one meets some of the brightest (and most eccentric) minds on Earth. Although I dislike air...
متن کاملTight junctions.
Tight junctions are the most apical intercellular junctions of epithelial and endothelial cells and create a regulatable semipermeable diffusion barrier between individual cells. On a cellular level, they form an intramembrane diffusion fence that restricts the intermixing of apical and basolateral membrane components. In addition to these well defined functions, more recent evidence suggests t...

B Confirming the diagnosis of night blindness in our patient, the scotopic response in his electroretinogram (ERG) was distinctly reduced while the photopic response was normal. When his blood was examined for a low level of vitamin A as a possible cause for night blindness, we found the value to be reduced below normal (17 pg/dl versus 25-70 pg/dl in normal subjects). Treatment with vitamin A ...
