Research Summary

Center/Research Area Affiliation


Dr. Ng's research is focused on drug discovery and development, as well as disease mechanisms at a preclinical level. His expertise lies in cell and molecular biology, molecular genetics, and animal model and assay development. Dr. Ng has significant experience applying basic experimental techniques and analyses to drive translational research. His current research projects include investigating the neuroprotective function of endogenous VEGF-A in ischemia- and inflammation-driven retinopathies and glaucoma; identifying novel targets for anti-angiogenesis and anti-inflammation in neovascular AMD, diabetic retinopathy, and retinopathy of prematurity; and characterizing a novel anti-inflammatory strategy for peripheral vascular disease.

His Story

When Dr Ng was a child, he became fascinated with how medications can make patients feel better so quickly. His interest in drug research grew during graduate school as he learned more about how drugs work. He was particularly excited by the new class of molecular therapeutics being developed that had been based on disease mechanism research and rational drug design. Because he had studied the biology of vascular endothelial growth factor (VEGF), he had the opportunity to help develop the first anti-VEGF therapeutic for age-related macular degeneration (AMD) at Eyetech Pharmaceuticals soon after graduate school. Being able to witness how this drug was helping patients with blinding eye diseases, while simultaneously applying his knowledge to drug discovery and development, validated his passion for translational vision research.

Today, he continues to study basic disease mechanisms for AMD and other blinding ocular diseases, and he aims to develop new and better therapeutic approaches. Current projects in his laboratory include validating novel targets for wet AMD and developing engineered VEGF for retinal neuroprotection. He strongly believes that his findings will contribute to the development of the next-generation of therapies for various blinding diseases.


Research Interests

  • Neuroprotective function of endogenous VEGF-A in ischemic- and inflammation-driven retinopathies, as well as glaucoma
  • Novel targets for anti-angiogenesis and anti-inflammation in neovascular AMD, diabetic retinopathy and retinopathy of prematurity
  • Characterizing a novel anti-inflammatory strategy for peripheral vascular disease

Novel Therapeutic Target for Choroidal Neovascularization

Dr. Ng aims to validate the functional role of toll-like receptor 2 (TLR2), a component of the innate immune system, in choroidal neovascularization (CNV) pathogenesis, and to evaluate TLR2 as a novel, effective, and safe therapeutic target for the treatment of CNV. His data suggest that activation of TLR2, expressed by the retinal pigment epithelium, induces inflammation that can drive CNV development. Also, the TLR2 pathway is separate from VEGF in CNV pathogenesis. Combination treatment with anti-TLR2 and anti-VEGF results in additive therapeutic effects in animal models of CNV. Dr. Ng is currently evaluating the therapeutic effects of targeting the TLR2 and its signal pathway for inhibiting CNV.

Novel Therapeutic for Diabetic Retinopathy

Strong evidences suggests that vascular inflammation driven by vascular endothelial growth factor (VEGF) contributes to the pathogenesis of diabetic retinopathy. Dr. Ng's research supports a role for the heparin-binding domain of VEGF in inducing inflammation in diabetic retinopathy. The goal of this project is to determine the therapeutic potential of targeting the heparin-binding domain of VEGF for inhibiting vascular inflammation associated with diabetic retinopathy. Dr. Ng is currently developing novel approaches to block the pro-inflammatory activity of the heparin-binding domain of VEGF aiming at developing a new therapy for diabetic retinopathy.

Proof of Concept Interventional Study with Engineered VEGF for Retinal Neuroprotection

Strong evidence supports a critical role for endogenous VEGF in retinal neuroprotection during various stress conditions and in diseases like glaucoma. The goal for this project is to develop an engineered VEGF molecule that has potent neuroprotection activity, but lacks the undesirable activities (such as inducing inflammation, vascular permeability, and angiogenesis). Dr. Ng has created the first set of engineered VEGF molecules and is currently testing their neuroprotective activities in neuronal cells in culture and also their effects on vascular endothelial cells and vessels.
