Mesenchymal stem cells (MSC) have become a promising tool for cell therapy in regenerative medicine. They are readily available, demonstrate powerful differentiation capabilities and present immunosuppressive properties that aid them in surviving from host immune rejection for its great potential use in allograft. Currently clinical trials are underway using MSC, both culture-expanded allogenei...
Among blood preparations, serum has been topically used in the management of various ocular diseases in ophthalmology. Like peripheral blood serum, umbilical cord blood serum contains a high concentration of essential tear components, growth factors, neurotrophic factors, vitamin A, fibronectin, prealbumin, and oil. Umbilical cord serum can provide basic nutrients for epithelial renewal and can...
Mutations in keratoepithelin are associated with blinding ocular diseases, including lattice corneal dystrophy type 1 and granular corneal dystrophy type 2. These diseases are characterized by deposits of amyloid fibrils and/or granular non-amyloid aggregates in the cornea. Removing the deposits in the cornea is important for treatment. Previously, we reported the destruction of amyloid fibrils...
Corneal Ulcer, also known as keratitis, represents the most frequently appearing symptom among corneal diseases, second leading cause of ocular morbidity worldwide. Consequences such irreversible eyesight damage or blindness require an innovative approach that enables a distinction to be made between patterns different ulcer stages lower global burden visual disability. This paper describes Con...
FK506 binding protein 12 (FK506BP) is a small peptide with a single FK506BP domain that is involved in suppression of immune response and reactive oxygen species. FK506BP has emerged as a potential drug target for several inflammatory diseases. Here, we examined the protective effects of directly applied cell permeable FK506BP (PEP-1-FK506BP) on corneal alkali burn injury (CAI). In the cornea, ...
Corneal epithelium is a self-renewing tissue. Recent studies indicate that corneal epithelial stem cells reside preferentially in the basal layer of peripheral cornea in the limbal zone, rather than uniformly in the entire corneal epithelium. This idea is supported by a unique limbal/corneal expression pattern of the K3 keratin marker for corneal-type differentiation; the preferential distribut...
The aim of this clinical study was to examine corneas extracted from the patients during penetrating keratoplasty for the presence of immunoglobulins and inflammatory cells that can be warning for the graft failure. Individual clinical diagnoses were correlated to the presence of the inflammatory signs in corneal tissue. The signs of inflammation in corneal layers were detected especially in gr...
Introduction & Objective: Corneal ulcer is one of the most important medical emergencies that in the absence of on time diagnosis and treatment can lead to loss of vision. Therefore, identification of microorganisms and their response to drugs in each region is important. The aim of this study was to determine the most common organisms that cause keratitis and antibiotic sensitivity in this reg...
In the present study, the effects of the acute and chronic oral administrations (po) of curcumin in the absence and presence of morphine and naloxone was investigated on the sensation of acute corneal pain in rats. Acute corneal pain was induced by the local application of hypertonic saline (5 M NaCl) on the corneal surface, and the number of eye wipes was then counted for 30 s. Subcutaneous (s...
PURPOSE A recent clinical report demonstrated that topical nerve growth factor (NGF) treatment in patients affected by corneal neurotrophic ulcers induced epithelial and stromal healing restoring corneal integrity. Mechanisms(s) undergoing these clinical NGF actions are still unclear. The aim of this study was to investigate the role of NGF in human and rat cornea physiopathology. METHODS Exp...
