RESEARCH

Dr. Lechleiter's laboratory is interested in the molecular and cellular mechanisms of protection during drug addition, ischemic stress, stroke, traumatic brain injury (TBI) and age-associated neurodegenerative diseases. Most strategies to reduce, slow and repair the severity of brain injuries and diseases have focused almost exclusively on neurons.

We have focused our research on the potential of astrocytes as a novel theurapeutic avenue for brain treatment.

Astrocytes are known to play a crucial role in supporting and protecting neuronal function and in modulating brain energy metabolism. A therapeutic strategy that increases energy production is inherently robust, since the number of potential neuroprotective processes that benefit are significantly higher than a single molecular target.
