ProMIS Neurosciences Presents at the 2022 American Academy of Neurology Annual Meeting


Dr. Beibei Zhao delivered a poster presentation entitled: “RACK1 Knockdown Alleviates TDP-43-Associated Global Translational Suppression in vitro and Neurodegeneration in vivo” during Session P3: Neuromuscular Disease: Amyotrophic Lateral Sclerosis 3, on Saturday, April 2nd. 


The receptor of activated C-kinase 1 (RACK1) is a well-conserved protein with more than 100 recognized activities. Co- aggregation of RACK1 with TDP-43 inclusions has been observed in sporadic ALS suggesting that it may be part of a pathogenic interactome involving the two proteins.


The poster addresses whether knockdown of RACK1 in mature cells may be beneficial against TDP-43 related pathology in cultured cells and in a living organism, the Drosophila fruit fly.  The results are consistent with the existence of a pathogenic interaction between TDP-43 and RACK1 in misfolded aggregates and support targeting of RACK1 to alleviate TDP-43 proteinopathy.


The poster abstract is available on the AAN website here. Dr. Zhao’s poster presentation will be available on the ProMIS website ( at the conclusion of the meeting.
