Published on: August 24, 2019
Summary
This study examines human elastinolytic proteinases, focusing on polymorphonuclear neutrophil (PMN) elastase. It explains the enzyme's persistent activity and its role in pulmonary diseases.
Area of Science:
- Biochemistry
- Cell Biology
- Immunology
Background:
- Elastinolytic proteinases are crucial enzymes involved in tissue remodeling and degradation.
- Polymorphonuclear neutrophils (PMN) are key immune cells that release potent proteases, including elastase.
- Dysregulation of these enzymes is implicated in various pathological conditions.
Purpose of the Study:
- To survey human elastinolytic proteinases, with a specific focus on PMN elastase.
- To discuss the properties, targets, and regulation of PMN elastase.
- To explore the role of elastase-mediated tissue injury in pulmonary diseases.
Main Methods:
- Literature review and synthesis of existing research on elastinolytic proteinases.
- Focus on biochemical and physiological properties of PMN elastase.
- Analysis of endogenous regulators and inhibitors of PMN elastase.
Main Results:
- PMN elastase exhibits significant activity against elastin in plasma and connective tissues.
- Endogenous inhibitors can be overcome, leading to persistent enzyme activity.
- Elastase-mediated tissue damage is a proposed mechanism in several lung diseases.
Conclusions:
- PMN elastase is a critical enzyme with implications for human health and disease.
- Understanding elastase regulation is vital for developing therapeutic strategies.
- Further research into elastase's role in pulmonary pathology is warranted.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the exudate's...

Elastin is Responsible for Tissue Elasticity
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Role of Matrix Metalloproteases in Degradation of ECM
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.

Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Phases of Wound Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...
