Astrocytes - brain cells named after their characteristic star-shape and previously thought to act only as the 'glue' between neurons, have a central role in the regulation of breathing, according to scientists. The finding provides a new dimension for research into fundamental principles of brain organization and function and may be relevant for understanding causes of devastating conditions associated with respiratory failure such as Sudden Infant Death Syndrome. The research, funded by the...

The leading cause of death in infants born prematurely is respiratory distress syndrome. It is caused by deficiency in a fat-protein complex known as lung surfactant, which is critical for optimal gas exchange in the lung. LPCAT1 is a recently identified mouse lung protein predicted, based on in vitro assays, to be involved in the generation of surfactant. Now, John Shannon and colleagues, at Cincinnati Children's Hospital Medical Center, have demonstrated that LPCAT1 has a crucial role in...

In turn, it effects the lungs, pancreas, liver, and intestines, as well as all other exocrine glands in the body. The most common genetic mutation that causes CF is a deletion of three nucleotides that results in a loss of phenylalanine, an amino acid at the 508th position on the protein. It should be noted, however, that there are over a thousand other mutations that...
