Complex Antibody Profile Changes in an Experimental Autoimmune Glaucoma Animal Model
2009
PURPOSE. Increased serum antibodies against heat shock protein 27 (HSP27) have been identified in patients with glaucoma. Immunization with HSP27 caused retinal ganglion cell (RGC) loss in animals. The authors analyzed whether HSP27 immunization not only causes RGC loss but also affects systemic antibody patterns. METHODS. Rats were immunized with HSP27 and were surveyed for 4, 5, and 6 weeks (groups 1-3). Control animals were humanely killed after 6 weeks (group 4). Intraocular pressure was measured before and 2 and 4 weeks after immunization. Fundus images were taken at the same time. Retinal flatmounts were prepared, and Brn-3a labeled RGCs were counted. Serum was collected during the st…
Serum autoantibodies to alpha-fodrin are present in glaucoma patients from Germany and the United States.

PURPOSE Glaucoma is characterized by a progressive loss of retinal ganglion cells that results in a characteristic optic neuropathy associated with visual field loss. In previous studies, changes in the antibody profiles have been shown in the sera of patients with glaucoma, and these findings suggest a role for autoimmune involvement in the pathogenesis of glaucoma in some patients. The purpose of this study was to compare the antibody profiles against optic nerve antigens in patients with glaucoma in two different study populations from Germany and the United States. METHODS One hundred twenty patients were included in the study, 60 from Germany and 60 from the United States: a control gr…

Enhanced characterization of serum autoantibody reactivity following HSP 60 immunization in a rat model of experimental autoimmune glaucoma.
2010
Antibodies against heat shock proteins have been identified in sera of human glaucoma patients in several studies and immunization with heat shock protein 60 (HSP 60) causes retinal ganglion cell (RGC) loss in an animal model of experimental autoimmune glaucoma. The aim of this study was to observe the time course of increased anti-retina antibody appearance in the serum and characterize the identification of prominent autoantibodies that accompany HSP 60 immunization in a rat model of experimental autoimmune glaucoma.Eight weeks after immunization with HSP 60 retinal flatmounts were prepared and RGCs were counted in eight predefined areas and compared to controls. Serum collected before, a…
Upregulation of antibody response to heat shock proteins and tissue antigens in an ocular ischemia model.
2011
PURPOSE. The aim of this study was to characterize the serum antibody reactivities occurring after ocular ischemia reperfusion. The time course of serum antibody responses was examined. METHODS. Wistar rats were exposed to transient ocular ischemia by elevating intraocular pressure to 130 mm Hg for 60 minutes. Axonal damage was evaluated on optic-nerve sections 2 and 4 weeks later. Blood samples collected before and several times after ischemia were used for antibody detection via customized protein microarrays. Different tissue antigens, including heat shock proteins (HSPs) and crystallins, were selected based on previous identification of antibody reactivities in studies on ischemic event…
