Immunopharmacology Comments
Cathepsins B, H and L have become important therapeutic targets as their proteolytic activity has been implicated in several pathological inflammatory conditions, such as arthritis and periodontitis. Therefore, pharmacological inhibitors of these enzymes are in development as novel therapeutics.
