Exposed tissue surfaces, including skin and mucous membranes, are under constant threat of attack by microorganisms in the environment. The layer of cells that line these areas, known as epithelial cells, are the first line of defense against these pathogens, but the underlying molecular mechanisms that allow them to repel microbes are unknown. In this issue of the Journal of Clinical Investigation, researchers at the University of California, Berkeley, report that epithelial cells in the...

Mucus Helps Clean Out Human Lungs

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of North Carolina, Chapel Hill recently published a study on their work to understand how human lungs clean out mucus from colds and allergy, making the airways free of foreign matter that may be toxic or infectious to the body. The findings, published in a recent issue of the journal Science, will help scientists identify issues related to human lung diseases like asthma, chronic obstructive...

Migratory birds and fish use the Earth´s magnetic field to find their way. LMU researchers have now identified cells with internal compass needles for the perception of the field — and can explain why high-tension cables perturb the magnetic orientation. Although many animal species can sense the geomagnetic field and exploit it for spatial orientation, efforts to pinpoint the cells that detect the field and convert the information into nerve impulses have so far failed....

The development of convenient, yet physiologically relevant in vitro culture systems is critical to research and development on chronic respiratory diseases such as asthma or COPD, and could accelerate the development of inhaled drug formulations. Vancouver, British Columbia (PRWEB) June 07, 2012 A new culture medium for more physiologically relevant differentiation of human bronchial epithelial cells has been released by STEMCELL Technologies. Cells cultured with PneumaCult-ALI at the...

In a study that holds major implications for breast cancer research as well as basic cell biology, scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, which the researchers call “CAMo,” for coherent angular motion, is necessary for the cells to...

The Biology Website EurekaMag.com publishes insights into all areas of biological and health science. The latest insights cover the Digestive System which consists of a series of hollow organs joined in a long, twisting tube from the mouth to the anus, and the Nervous System which is is an organ system containing a network of neurons that coordinate the actions of an organism and transmit signals between different parts of its body. The insight into Photosynthesis covers the chemical process...

How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories. The study, headed by Eduard Batlle, coordinator of the Oncology Programme at IRB Barcelona and ICREA Research Professor, is published in...

Developmental processes are increasingly well-characterized at the molecular and cell biological levels, but how more complex tissues and organs involving the coordinated action of multiple cell types in three dimensions is achieved remains something of a black box. One question of particular interest and importance is whether signaling interactions between neighboring tissues are essential to guiding organogenesis, or whether these can arise autonomously from developmental routines inherent...

Chemical images now much more detailed With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM), led a team of researchers from UWM, the University of Illinois at Urbana-Champaign and University of Illinois at Chicago (UIC) to demonstrate these new capabilities....
