Ocular Immunology and Angiogenesis Laboratory at the 果冻影院

Dr Chaurasia’s Ocular Immunology and Angiogenesis Lab is funded by NIH/NEI and focuses on the Molecular Basis of Eye Diseases for the development of a highly innovative basic and translational multidisciplinary research program in the identification and validation of novel biomarkers and targets and evaluate potential VEGF-independent Next-Generation Precision therapeutics/Medicine to treat Ocular Fibrotic and Angiogenic Diseases (OFADs).

Support the Ocular Immunology and Angiogenesis Laboratory

The OIAL could not exist without the generosity and support of many foundations, federal agencies and individual donors. Funds donated to the program are used to acquire new equipment and research consumables, to help train students and fellows, to enable the presentation of our research findings at scientific meetings, and to fund positions for support staff.

Research Overview

Dr. Chaurasia鈥檚 Ocular Immunology and Angiogenesis Lab uses state-of-the-art multimodal in vivo ocular imaging tools such as slit lamp microscopy, optical coherence tomography (OCT), and electroretinography (ERG) to clinically evaluate animal disease models for corneal and retinal degenerative diseases. The lab extensively employs cellular and molecular techniques in vitro using primary and ocular cell lines and ex vivo using rodent and pig eyes to screen compounds and perform pharmacokinetic studies to evaluate next-gen drugs for Ocular Fibrosis, Angiogenesis, and Chemical Toxicity. Dr. Chaurasia has 25+ years of experience in basic and translational vision sciences, evidenced by 120+ peer-reviewed research papers and 200+ scientific abstracts and presentations at the national and international level.

Research Areas

Role of S100 proteins in Diabetic Retinopathy

The S100 family of small Ca2+-binding proteins is involved in many inflammatory diseases, but their role in the retina is still unknown. Our preliminary studies identified for the first time a regulatory role of S100A9 protein in rodents and porcine retina along with human DR patients. The present study will evaluate the functional role of S100A9 in the retina and explore its possibility of being a novel VEGF-independent molecular target in DR pathogenesis.


Decorin Gene Therapy for Retinopathy of Prematurity

Decorin is a small leucine-rich proteoglycan that regulates the extracellular matrix and angiogenesis in many tissues, but its function in the retina remains unknown. Our pilot studies suggest a role for decorin in retinal structural integrity and microvasculature. The present study will characterize the functional role of Dcn in the retina and test the potential of AAV5-Dcn gene therapy for the treatment of retinopathy of prematurity using an established oxygen-induced retinopathy rat model.

Ossabaw minipig as a Translational Model for Diabetic Retinopathy

This is the first study to describe the ultrastructural neuronal and vascular changes in the retina of young Ossabaw pigs fed a Western diet, simulating early signs of diabetic retinopathy pathogenesis.


3D Characterization of Ultrastructural Retinal Changes with Focus Ion Beam-Scanning Electron Microscopy (FIB-SEM)

This study aims to quantify the 3D ultrastructure changes in the RPE cell damage, drusen volume and Bruch's membrane using FIB-SEM in the patients with age-related macular degeneration (AMD).
