Objectives and lines of research
Objectives
1. Description of the molecular mechanisms involved in the pathophysiology of corneal ectasias.
2. Description of the proteomic alterations from the preclinical stage of keratoconus disease; in association with the corneal tomographic and biomechanical study.
3. Preclinical development of diapeutic nanoparticles for keratoconus based on the potential of the pharmacological effect of lactoferrin.
4. Identification of tear biomarkers for the detection of neurodegenerative diseases.
