Another proteinase that has been implicated in COPD pathogenesis is cathepsin S, a lysosomal acidic proteinase which is highly expressed by cells implicated in COPD pathogenesis including macrophages and dendritic cells [6].
We hypothesized that plasma concentrations of cathepsin S and cystatin C would differ between COPD patients, subjects with cough and sputum, and healthy smokers and nonsmokers.
Medivir AB (OMX:MVIR) (STO:MVIRB.ST), an emerging research-based pharmaceutical company, announced today the selection of its drug, MIV-247, as a candidate drug (CD) from its cathepsin S inhibitor project for the treatment of neuropathic pain.
According to the company, MIV-247, which is also entering non-clinical development, is a potent and highly selective inhibitor of cathepsin S, an enzyme shown to be important for the maintenance of the neuropathic pain state, through its action in releasing fractalkine (a pro-inflammatory protein) in areas of the spinal cord important for pain sensation.
The methods depend upon inhibiting invariant chain proteolysis by cathepsin S from class II MHC/invariant chain complexes, thereby reducing the competency of class II MHC molecules for binding antigenic peptides, reducing presentation of antigenic peptides by class II MHC molecules, and suppressing immune responses.
During the latest quarter, Celera received $3 million in revenue from the resale of its cathepsin S inhibitor program to a privately held drug development company.
Cathepsin S (CatS) belongs to the family of lysosomal cysteine proteases that are normally present in lysosomes.
