Proteases and RONS
| Question | Answer |
|---|---|
| proteases | play central role in host defense, removal of damaged tissue, tissue repair and inflammation |
| matrix metalloproteinases | degrade extracellular matrix proteins |
| tissue inhibitors of metalloproteinases | endogenous inhibitors of matrix metalloproteinases |
| serine proteases | released from neutrophils |
| SERPINs | endogenous inhibitors of serine proteases |
| synthetic MMP inhibitors | peptidomimetics that bind to the catalytic zinc region and prevent activation of the enzyme |
| ROS | reactive oxygen species such as superoxide and hydrogen peroxide |
| respiratory burst | production of ROS by leukocytes as a host defense mechanism against invading bacteria or other microorganisms |
| lipoic acid | anti-oxidant used in the treatment of multiple sclerosis |
| regulation of proteases by RONS | activation of MMPs and inactivation of SERPINs |
