Pascale Alard,
Ph.D. We are interested in understanding the events that lead to autoimmune diabetes in NOD mice. Our work focuses on a population of CD25+ regulatory T cells, which appears to be crucial in the control of autoimmune diseases. Dysregulation of the immune response, including aberrant T cell and antigen presenting cell (APC) function, plays a major role in the induction of diabetes in NOD mice. More importantly, NOD mice exhibit quantitative and functional deficiencies in CD4+CD25+ regulatory T cells. We hypothesize that an alteration of this regulatory T cell population could lead to diabetes. Our preliminary studies indicate that inappropriate activation by NOD APC could be in part responsible for the dysfunction of CD4+CD25+ regulatory T cells in NOD mice. Our objective is to characterize the potential defect leading to non-functional CD4+CD25+ regulatory T cells in NOD mice, and to restore a functional regulation. July 1, 2002 |

Atherton My pre-doctoral training in virology was followed by two postdoctoral training experiences. My first postdoctoral fellowship was in the laboratory of Dennis J. O’ Callaghan, Ph.D. on a project to study the molecular biology of equine herpes viruses. My second postdoctoral fellowship was in the laboratory of J. Wayne Streilein, M.D. on a project that evolved to a study of the pathogenesis of herpes virus infection of the retina following inoculation of virus into the anterior chamber of the eye. After faculty positions first at the University of Miami School of Medicine and then at the University of Texas Health Science Center in San Antonio, I relocated to the Medical College of Georgia in May 2000 to become the Chair of the Department of Cellular Biology and Anatomy. My research interests are in the pathogenesis of herpes virus infections of the eye and brain and in the use of animal models to study the pathogenesis of human ocular diseases. |

M.D., Ph.D, Corneal transplantation immunology is my major research interest. I have reported suppression of orthotopic corneal allo-rejection by blocking LFA-1/ICAM-1, VLA-4/VCAM-1, or B7/CD28 adhesion, in partial fulfillment of the requirements for a Ph.D degree. As Dr. Streilein’s postdoctoral fellow, I have worked on heterotopic corneal transplantation beneath the kidney capsule to show that corneal epithelium displays potent immunogenicity, whereas, corneal endothelium confers immune privilege on the epithelium-deprived corneal to establish composite corneal allografts composed of syngeneic epithelium and allogeneic stroma plus endothelium in vitro, which fail to induce allo-sensitization after orthotopic grafting - even in high-risk recipients. Evaluation of persistence and replacement of donor and recipient cells after orthotopic corneal transplantation using “green mouse”, and determination of immune privilege of neural progenitor cells have also been done during my fellowship period. In my current appointment, immunological analyses of both corneal transplantation and amniotic membrane transplantation to the ocular surface have been underway. July 1, 2002 |

J. Jager Dr. Martine J. Jager combines a clinical practice as ophthalmologist with basic eye research. After studying Medicine at Leiden University, The Netherlands, Dr. Jager worked for several years at the Department of Immunohaematology and Bloodbank under the supervision of Prof. Jon van Rood. She received her PhD for the identification of two new polymorphic antigens present on monocytes, and developed a keen interest in the biological role of MHC antigens. After a residency in Ophthalmology at the University of Amsterdam, The Netherlands, she spent time in the laboratory of Prof. Wayne Streilein in Miami, and did a fellowship in Corneal diseases at the Bascom Palmer Eye Institute in Miami. After her return to the Netherlands on a Fellowship of the Royal Netherlands Academy of Arts and Sciences, she had the opportunity to develop a laboratory for immunological-ophthalmological research. Students and medical doctors are trained in ocular immunology and publications concern a wide range of ocular research areas. Specific topics are mechanisms of rejection of intraocular tumors (together with Dr. R.E.M. Toes and Prof. C.J.M. Melief), HLA expression, angiogenesis and other prognostic factors in uveal melanoma, and gene-expression profiling in melanoma (together with Dr. N.A. Gruis). Clinically, the focus is on ocular surface diseases. International collaboration is considered of great importance, and students are stimulated to go abroad. Collaboration with Prof. Streilein was strenghtenen by a visiting Associate Professorship as few years ago, and by a continuous contribution of Dutch students to the Schepens Eye Research Institute. |

Kezuka, M.D., Ph.D. Dr. Kezuka’s major interests are in ocular immunology, research of immune privilege in the anterior chamber, termed anterior chamber associated immune deviation. While a post-doctoral fellow in the Schepens Eye Research Institute, he analyzed the functional properties of CD4+ and CD8+, OVA-specific T cells stimulated in vitro with OVA-pulsed, TGFb2-treated antigen presenting cells. Since returning to Japan, he has probed the possible relationships between reactivated varicella-zoster virus (VZV) infection, delayed hypersensitivity to VZV antigens, and the presence of VZV-related eye diseases. His future research plans are to analyze the suppression of experimental autoimmune uveoretinitis using the neuropeptides CGRP and VIP. July 1, 2002 |

Kitazawa, Ph.D. From 1981 to 1982 involved as research fellow in the immunochemical studies of epidermal growth factor (EGF) at University of Shizuoka School of Pharmaceutical Sciences. From 1985 to 1986 pursued studies on the purification and characterization of hepatocyte growth factor and TGF-beta binding protein at the Institute for Enzyme Research, University of Tokushima. From 1988 to 1994 pursued at Otsuka studies on the effect of EGF on corneal epithelial wound healing and its mechanism of action. From 1995 onward conducting basic research and studies associated with the development of therapeutics in cutaneous immunity and inflammation including atopic dermatitis. During the period 1998 to 1999 I conducted a study on the mechanism of delayed systemic effect of UVB and UVB-induced tolerance under the direction of Dr. Streilein at the Schepens. Currently in charge of the documentary and experimental evaluation of
therapeutics offered for license in ophthalmologic and dermatological
fields. |

Takeuchi, M.D., Ph.D. I have characterized at molecular and cellular levels TGFb-2 treated antigen presenting cells (APCs) with ACAID-inducing properties. It has been found that TGFb-2-treated APCs possess the capacity to create a microenvironment that is rich in TGFb yet deficient in IL-12. In this microenvironment, TGFb-2-treated APCs fail to up-regulate expression of CD40. While these antigen-pulsed APCs are readily able to activate specific T cells in vitro (to proliferate and secrete IL-2), the responding T cells secrete IL-4 and TGFb, but not IFN-g. My current efforts have centered on the study of altered immune responses and immune privilege in the eye of patients suffering from Behcet’s disease. The analysis is being undertaken by molecular biological techniques. July 1, 2002 |

MD. PhD. Dr. Kouichi Ohta is an ophthalmologist particularly interested in ocular immunity and inflammation. He is a chief of cornea and uveitis service. He also works as a surgeon of corneal transplantation, cataract and vitreo-retinal disorders at Shinshu University Hospital. Dr. Ohta received his M.D. and Ph.D. degree from Shinshu University School of Medicine. His initial research work was characterization of infiltrating lymphocytes in anterior chamber of patients with uveitis. He pursued post-doctoral training in immunology at the Schepens Eye Research Institute. The effects of experimental ocular inflammation on ocular immune privilege were studied at Wayne’s laboratory. He also found IL-6 antagonizes TGF-beta and abolishes immune privilege. The mechanism and new therapy for ocular inflammation using endotoxin-induced uveitis and ischemia-reperfusion retinal injury model are now investigated at Shinshu University. July 1, 2002 |
