...s in the lungs and leads to accumulation of thick, sticky mucous that is not only difficult to clear, but also provides a breeding ground for bacteria. "Certainly many things contribute to chronic sinusitis in people who have no known family history of cystic fibrosis," says Dr. Cutting.

... As the cells move into the wound, they lay down a sticky bed of proteins including laminin 5. The chemical signals dissipate as the wound heals, but to fine-tune their position the cells now use alpha(3)beta(1) to crawl over the laminin 5. At some stage, however, the cells need to stop moving and settle ...Tea fights cavities, reduces plaque
