Targeting the Cell’s Stress Pathways for Therapeutic Benefit

Speaker: Peter Walter (USA)
Organizer: Dusanka Milenkovic

There will be wine and cheese and the possibility for further discussion after the talk.

About the talk:

From leaving their ribosome cradles to their demise in the fangs of proteolytic enzymes, proteins continuously explore different folding states. In most cell compartments, molecular sensors carefully monitor protein folding and instruct downstream effectors to take corrective actions as needed. In response, cells can make adjustments to their protein folding and degradation machineries to stay in a healthy state of homeostasis. If protein folding defects occur and cannot be corrected sufficiently and timely, cells induce suicide programs. Programmed cell death is thought to protect an organism from malfunctioning, rogue cells that result from an accumulation of defective protein. In various pathologies, the life/death balance can inappropriately err on either side: killing cells that would be beneficial if kept alive, or alternatively inappropriately protecting dangerous, disease propagating cells. Studies of the regulation of proteostasis now emerge as focal points of foundational basic research that powerfully connects to a wide spectrum of unmet clinical needs.
We will discuss advances in our lab’s efforts to understand the molecular details of the unfolded protein response (UPR), a conserved signaling network that surveys the protein folding status in the endoplasmic reticulum. The UPR signals through three molecularly distinct branches. The development of small, drug-like molecules that selectively target each of the UPR’s signaling branches has opened promising new therapeutic opportunities in areas as divergent as cancer, neurodegeneration, diabetes, inflammation, aging, and cognition. As such, the UPR emerges as a prime example of the power of fundamental cell biological discoveries to address problems of immense societal impact.
