Professional Interests:

Our research studies focuses on the pathogenesis of intraventricular hemorrhage (IVH) and development of neuro-protective strategies to prevent brain damage after IVH in premature infants. Current therapeutic strategies to treat IVH or prevent the resultant white matter brain injury have been largely unsuccessful.

Stem cells of different sources, such as human cord blood (CB) mononuclear cells, CD34+ CB and mesenchymal stem cells (MSCs) offer great promises in the treatment of a variety of neurological disorders on both preclinical and clinical studies. There have been no published investigations on the safety and efficacy of stem cell therapy in IVH. Our laboratory research is focusing to determine the safety and efficacy of stem cells with regenerative properties in a rabbit model of IVH. Our research goal are to evaluate pathologies associate with brain hemorrhage. And to improve the brain developmental outcome using genetic, pharmacological and stem cell therapeutic approaches after intraventricular hemorrhage in a translational premature rabbit model. Our work is related to both the aspect of research of neonatal brain development and neurological disorders. Dr. Vinukonda is awardee of Scientist Development Grant Award from American heart Association at national level.

1. Germinal matrix-intraventricular hemorrhage (GMH-IVH): Investigating potential therapeutic approaches for the treatment of pathogenesis of intraventricular hemorrhage (IVH) causing- white matter injury, reduced neurogenesis and post hemorrhagic hydrocephalus.
2. Novel Stem Cell therapy for germinal matrix-intraventricular hemorrhage (GMH-IVH): Investigating pathogenesis of (IVH), post hemorrhagic hydrocephalus, and white matter injury.
3. Consequences of glycerol induced diffused alveolar hemorrhage in premature rabbit pup model and treatment approaches for lung damage: Diffused alveolar is bleeding from many alveolar spaces throughout the lungs. Premature infants commonly associated with pulmonary and diffused alveolar hemorrhage and it occurrence is 1 in 1000 births. The common problem associated with alveoli hemorrhage is pulmonary edema, fibrosis, hypoxia and acute inflammation causing the lung damage. There is no well-established animal model of diffused alveolar hemorrhage to study the lung damage caused by blood and blood born components in prematurity. We have developed i.p. glycerol induced diffused alveolar hemorrhage in premature rabbit pups.
