Transmembrane proteases as disease markers and targets for therapy

Area of Science:

• Biochemistry
• Cell Biology
• Enzymology

Background:

• Transmembrane proteases (ectoproteases) are enzymes located on cell surfaces.
• They are expressed in diverse cell types, including endothelial, epithelial, and hematopoietic cells.
• These proteases play roles in modulating cellular functions.

Purpose of the Study:

• To investigate the biological roles of transmembrane proteases.
• To explore their involvement in major cellular events like proliferation, survival, and invasiveness.
• To assess their potential as disease biomarkers and therapeutic targets.

Main Methods:

• Characterization of natural and synthetic inhibitors of transmembrane proteases.
• Analysis of ectoenzyme activity and its impact on bioactive peptide responses.
• Investigation of dysregulated expression patterns in human diseases.

Main Results:

• Ectoenzymes modulate bioactive peptide responses.
• Transmembrane proteases influence critical cellular processes such as proliferation, survival, and invasiveness.
• Dysregulated expression is linked to human diseases.

Conclusions:

• Transmembrane proteases are key regulators of cellular functions.
• Their dysregulation in disease highlights their pathophysiological significance.
• These enzymes represent promising targets for therapeutic intervention and diagnostic markers.
