Soluble Fas and Fas ligand in human tear fluid after photorefractive keratectomy.
BACKGROUND/AIMS The Fas-Fas ligand system is thought to be involved in stromal cell apoptosis after corneal wounding. The aim was to measure changes in human tear fluid levels of soluble Fas (sFas) and Fas ligand (sFasL) following myopic photorefractive keratectomy (PRK). METHODS Tear samples of 59 patients were collected preoperatively, and 1 or 2 days after PRK. Tear fluid sFas or sFasL con...
متن کاملSoluble Fas ligand and soluble Fas in ocular fluid of patients with uveitis.
AIMS To investigate the presence of soluble Fas ligand (sFasL) and soluble Fas (sFas) in ocular fluid of patients with uveitis. METHODS Samples of aqueous humour (AH, n=17), vitreous fluid (n=9), and serum (n=60) were collected from patients with uveitis which included Behçet's disease, Vogt-Koyanagi-Harada disease, sarcoidosis, human T lymphotropic virus type 1 (HTLV-I) uveitis, sympathetic ...
متن کاملTear fluid plasmin activity after excimer laser photorefractive keratectomy.
PURPOSE Elevated tear fluid plasmin activity may correlate with delayed healing of corneal wounds. The present study was performed to establish the tear fluid plasmin activity after photorefractive keratoablation (PRK). METHODS Tear fluid aspirated with microcapillaries was subjected to a fluorometric plasmin assay using the 7-amido-4-trifluoromethylcoumarin derivate of the tripeptide H-D-Val...
متن کاملAqueous Humor Levels of Soluble Fas and Fas-ligand in Patients with Primary Open Angle and Pseudoex-foliation Glaucoma
Background: Glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. In patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. Death of the trabecular meshwork cells may be a result of apoptosis. Objective: To investigate the aqueous humor levels of soluble Fas (sFas) and Fas-Ligand (sFasL) in ...
متن کاملMembrane Fas Ligand Kills Human Peripheral Blood T Lymphocytes, and Soluble Fas Ligand Blocks the Killing
It has been believed that the Fas expressed on human peripheral blood T cells (PBT) is nonfunctional, because these cells are insensitive to agonistic anti-Fas/Apo-1 mAbs that efficiently kill in vitro-activated T cells and many Fas-expressing cell lines. Here, we demonstrate that membrane-bound Fas ligand (FasL) kills both fresh and in vitro-activated PBT, indicating that the Fas expressed on ...
