Research Goals
Our goal is to understand the molecular mechanisms of neuronal development and regeneration, and to utilize gained knowledge in developing translational approaches for repairing injured central nervous system (CNS) circuits.

Preprints of two research papers from our lab are now available at bioRxiv. The articles include links to the scRNAseq-based Subtypes Gene Browser, in one article for uninjured and injured optic nerve oligodendrocytes, and in the other article for adult uninjured and injured RGCs (the latter re-analyzed using next generation algorithms from raw data by Tran et al. 2019): Post-injury born oligodendrocytes integrate into the glial scar and inhibit growth of regenerating axons by premature myelination and Retroactive analysis of single cell transcriptome profiles using next-generation algorithms revised the identification of several resilient retinal ganglion cell types

June, 2017
Dr. Trakhtenberg (lead PI) and Dr. Crocker (co-PI) were awarded a seed grant by the Connecticut Institute for the Brain and Cognitive Sciences (IBaCS). The grant will fund a research project to test a novel hypothesis regarding why axonal connections, through which neurons in the brain communicate with each other over long distances, do not regenerate after traumatic or stroke injury.
April, 2017
Dr. Trakhtenberg was awarded a research grant by the BrightFocus Foundation under the National Glaucoma Research Program. The grant will fund a research project aimed at investigating novel gene therapy approach towards developing neuroregenerative treatments for restoring vision after angle-closure glaucoma and other types of optic neuropathies, which lead to complete or partial blindness.

Projects in the lab revolve around fundamental questions in neuronal development and regeneration in the CNS. We integrate cutting edge molecular, biochemical, genetic, bioinformatics, and translational approaches, which involve:
- Histology and neuroanatomical analysis using confocal microscopy
- Rodent CNS in vivo injury models and gene therapy
- Neuronal cell culture and transfection
- Next-generation sequencing and neuro-bioinformatics
