Research Description:

The major research focus of the Vemuganti lab is to understand the mechanisms of brain damage and regeneration after stroke. The lab has a long-term interest in understanding the significance of post-ischemic neurogenesis with a goal to reinforce it with growth factors and cytokines. We are also interested to evaluate if the transplanted induced pluripotent stem cells (iPS cells) survive, increase the plasticity and functional recovery in the injured brain. We are also studying the role of non-coding RNAs in brain damage and regeneration. We are the first lab to demonstrate that ischemia significantly alters the cerebral microRNAs as well as piRNAs and LncRNAs. As these are upstream to pathways that promote regeneration and tolerance to ischemia, we are exploring their functional significance in the post-stroke brain.
