Research methods employed by the Sharma lab

Vascular inflammation plays a critical role in the pathogenesis of diabetic retinopathy. Building on my experience in vascular biology and genomic medicine, my current research focuses on understanding the role of endothelial dysfunction on vascular attributes of diabetic retinopathy. The long-term goal of my lab is to study the role of interleukin-6 (IL-6) signaling in diabetic retinopathy and uncover precise molecular mechanisms to develop novel therapeutic targets. We are currently testing a pharmacological compound, sgp130Fc (fused chimera of extracellular gp130 and the Fc region of IgG1), to selectively inhibit the IL-6 trans-signaling pathway to prevent the inflammation and retinal vascular dysfunction associated with diabetic retinopathy. My lab utilizes both in-vitro and rodent models of diabetic retinopathy to conduct our research.

  • Targeting of interleukin-6 classical and trans-signaling in diabetic retinopathy
  • Proteomics, glycomics, and glycoproteomic profiling in vision research
  • Discerning molecular mechanisms associated with glaucomatous optic neuropathy (glaucoma)

Noninvasive technique collects sufficient tear fluid to look for biomarkers of health and disease

Jagwire | May 27, 2022

The protective outer layer of our eyes, called the tear film, contains thousands of proteins, which provide clues about wellness and disease, and scientists have fine-tuned what they say is a non-invasive and efficient way to look at those clues.

They anticipate that one day a tear fluid workup could be as routine as bloodwork during a physical exam as well as in diagnosing a myriad of conditions from dry eye disease to Alzheimer’s.
