The role of reactive gliosis in Proliferative vitreoretinopathy (PVR).
In acute injury of the retina such as retinal detachment or ocular trauma, proliferative vitreoretinopathy (PVR), an excessive retinal gliosis in complex with inflammatory, excessive wound healing and remodeling processes, is a major barrier of surgical repair, leading to blindness despite the tremendous technological advancement in modern retinal surgery. The complex process of PVR formation has not been completely understood until now and currently, there is no subsiding or complete treatment available. Our ultimate goal is to explore the first initiatory event in PVR, focusing on reactive retinal gliosis, handling human tissue samples, primary cultured retinal cell lines, and mouse animal models of PVR. We use various laboratory techniques, including protein assay, immunohistochemical stain, and gene expression analysis. We are also using single-cell RNA seq, single-cell mass cytometry and imaging mass cytometry collaborating with Oklahoma Medical Research Foundation (OMRF).
Modification of proliferative gliosis in advanced age-related macular degeneration (AMD).
Disciform scars form the advanced stage of exudative AMD in which the retinal tissue is replaced by fibrotic scar tissue. Disciform scars lead to marked destruction of all retinal layers associated with severe vision loss. Our lab seeks a therapeutic approach in this advanced form of AMD via modifying proliferative gliosis.
The role of reactive gliosis and neuroretinal degeneration in Diabetic Retinopathy.
Our goal in this project is to elucidate the metabolic role of Müller gila in early advanced diabetic retinopathy and its links to chronic inflammation, hypoxia, and cellular proliferation.
Current Lab Members
Dr. Gopa Kumar received his Ph.D. degree in Biochemistry (2015) from the Mahatma Gandhi University, India. His graduate work focused on the radioprotective effects of nanoparticle based drug combinations in tumor animal models. His current research interest is on the exosomal trafficking of proteins and their potential benefits in the ophthalmic disease’ treatments.
James is a graduate from Oklahoma City University (Oklahoma City, OK) and The University of Oklahoma (Norman, OK) who has been working at OUHSC since 1999.
He has mass spectrometry background focusing on proteomics and biochemical pathway analysis. He is also an Adjunct Instructor at OSU-OKC.
Dr. Pollalis graduated from National and Kapodistrian University of Athens, Faculty of Medicine on 2018 and has a general interest in surgical retinal research.
