LMU researchers led by Christian Weber have, for the first time, elucidated how cells that promote the development of atherosclerosis find their way to the blood vessel wall, where they stimulate the formation of obstructive deposits. http://medicalxpress.com/news/2013-02-monocyte-migrations.html Medical research Tue, 19 Feb 2013 11:50:01 EST news280495879 Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer. http://medicalxpress.com/news/2013-02-cells-phenomenon-longevity-bonds.html Medical research Thu, 14 Feb 2013 13:35:10 EST news280071280 Nestled deep within the body, the epithelial lining of the respiratory system is nonetheless seriously exposed. Its direct contact with environmental air necessitates protective mechanisms that both seal off the respiratory tract from other compartments of the body and neutralize microbial invaders. This is achieved by the coordinated action of the functionally specialized various cell types that make up the lining of the airway. These respiratory cell populations include major ciliated cells, exocrine Clara cells, and neuroendocrine (NE) cells, all of which are generated by a common epithelial progenitor cell type during embryogenesis. http://medicalxpress.com/news/2013-01-airways-notch-bronchial-cell-fates.html Medical research Tue, 22 Jan 2013 07:31:21 EST news278062267 Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs). http://medicalxpress.com/news/2012-10-scientists-view-brain-protein-results.html Medical research Wed, 10 Oct 2012 13:00:12 EST news269092277 Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells. http://medicalxpress.com/news/2012-05-breast-stem-cell-receptor-teamwork-required.html Cancer Wed, 30 May 2012 13:40:01 EST news257602172 Macrophages playing an important role in the immune system eat and fight against pathogens and foreign substances in the very beginning of infection.
