Scientists discover mechanisms that could explain high risk of complications from lung infections in Down syndrome

Researchers have discovered two major mechanisms that contribute to the high risk of complications from lung infections in individuals with Down syndrome: poor ciliary function, which impairs the respiratory tract's ability to clear mucus and viral particles, and immune hyper-reactivity, which leads to an overactive immune response. Th...
