“The Ly6 superfamily, present in most metazoan genomes, codes for different cell-surface proteins and secreted ligands containing an extracellular motif called a Ly6 domain or three-finger domain. We report the identification MAPK Inhibitor Library cell assay of 36 novel genes coding for proteins of this family
in Drosophila. One of these fly Ly6 proteins, coded by the gene boudin (bou), is essential for tracheal morphogenesis in the fly embryo and contributes to the maintenance of the paracellular barrier and the organisation of the septate junctions in this tissue. Bou, a glycosylphosphatidylinositol anchored membrane protein, is also required for septate junction organisation in epithelial tissues and in the chordotonal organ glial cells, but not in the central nervous system. Our study reveals interesting parallelisms between the Ly6 proteins of flies and vertebrates, such as Staurosporine chemical structure the CD59 antigen. Similarly to this human protein, Bou travels from cell to cell associated with extracellular particles and, consistently, we show that it is required in a non-cell-autonomous fashion. Our work opens the way for future studies addressing the function of Ly6 proteins using Drosophila as a model system.”
“PURPOSE. This study evaluated the clinical outcomes of a combined
method of scraping corneal epithelium, coagulating vessels, and subconjunctival bevacizumab in Descemet stripping automated endothelial keratoplasty (DSAEK) for bullous keratopathy with corneal neovascularization (NV).\n\nMETHODS. The study included patients with bullous keratopathy undergoing DSAEK. Indications for DSAEK were advanced pseudophakic bullous keratopathy with superficial and deep corneal vascularization and SBE-β-CD datasheet failed corneal grafts. Patients were treated by scraping the corneal epithelium and lightly coagulating the corneal superficial stromal NV and the feeding vessels in the sclera, with a subconjunctival bevacizumab injection at the end of
surgery. Subconjunctival and perilimbal bevacizumab dose of 2.5 mg/0.1 mL/affected quadrant was injected at the site of NV in each patient at the end of surgery. One or 2 injections were applied. At each visit, a full eye examination with photographic documentation was performed. Mean follow-up 3 period was 32 (24-36) months.\n\nRESULTS. Eight eyes of 8 patients with high-risk corneal transplantation and corneal NV were included in this noncomparative interventional case series. The original corneal NV disappeared in all patients immediately after surgery. No patient in the series had recurrent corneal NV or rejection during at least 24 months of follow-up.\n\nCONCLUSIONS. The combination of scraping, coagulating, and bevacizumab injection in DSAEK is an effective method to treat corneal NV in corneal transplantation for bullous keratopathy.”
