Proteinase-activated receptor-2 and human lung epithelial cells: disarming by neutrophil serine proteinases.

abstract：:The extracellular matrix in asthmatic lungs contains abundant low-molecular-weight hyaluronan, and this is known to promote antigen presentation and allergic responses. Conversely, high-molecular-weight hyaluronan (HMW-HA), typical of uninflamed tissues, is known to suppress inflammation. We investigated whether HMW-H...
