Effect of Corneal Nerve Ablation on Immune Tolerance Induced by Corneal Allografts, Oral Immunization, or Anterior Chamber Injection of Antigens
Purpose Severing corneal nerves during corneal transplantation does not affect first corneal transplants, but abolishes immune privilege of subsequent corneal allografts. This abrogation of immune privilege is attributable to the disabling of T regulatory cells (T regs) induced by corneal transplantation. The goal of this study was to determine if severing corneal nerves induces the development...
متن کاملThe immune privilege of corneal grafts.
Keratoplasty is the oldest and one of the most successful forms of solid tissue transplantation. In the United States, over 33,000 corneal transplants are performed each year. Unlike other forms of tissue transplantation, keratoplasties are routinely performed without the aid of tissue typing or systemic immunosuppressive drugs. In spite of this, 90% of the first-time corneal transplants will s...
متن کاملInduction of Bone Marrow Stromal Cells into Cholinergic-Like Cells by Nerve Growth Factor
Background: Bone marrow stromal cells (BMSC) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. However, the transdifferentiation of BMSC into cholinergic phenotype requires more investigation. Methods: BMSC were isolated from adult rats, pre-induced with β-mercaptoethanol (BME) and followed by nerve growth factor (NGF) indu...
متن کاملLoss and restoration of immune privilege in eyes with corneal neovascularization.
PURPOSE To delineate the time course for loss of immune privilege after induction of corneal neovascularization (NV), and to test whether treatment with angiostatic agents can restore the eye's capacity to induce anterior chamber-associated immune deviation (ACAID). METHODS Corneal NV in murine eyes was induced by placement of intrastromal sutures. At different time points after NV induction,...
متن کاملsecond language acquisition of telicity and aspect by persian learners of english
این تحقیق از دو قسمت اصلی تشکیل شده است: در قسمت اول فراگیری ختمیت به ویژه درک و تولید اینگونه جملات توسط فراگیران ایرانی زبان انگلیسی مورد بررسی قرار گرفته است. قضاوت تعدادی انگلیسی زبان بر روی این جملات نیز هدفی دیگر بود که در این رساله بررسی شده است. از موضوعات دیگر تفاوت بین نشانه های ختمیت در زبان انگلیسی و فارسی و تاثیر زبان اول فراگیران در درک و تولید اینگونه جملات است. در قسمت دوم استفا...
