Research

The lab of Christian Behl has a long-standing interest in neurodegenerative disease with a focus on autophagy, proteostasis and oxidative stress. The continuing goal of this research is to uncover molecular maintenance processes that allow neurons to survive long-term challenges that occur during aging and neurodegeneration. One key process enabling cells to clear aggregation-prone disease proteins that accumulate over time is BAG3-mediated selective macroautophagy, an autophagic/lysosomal degradation process that is highly regulated by several co-factors and at a post-translational level. Moreover, this pathway appears to be involved in long-term adaptation of neuronal cells to redox stress. Further, employing C. elegans as an in vivo model, the Behl group identifies novel regulators of autophagy with a focus of genes/proteins linked to neuronal disease, such as small Rab GTPases and RABGAPs.
