A Comprehensive Drosophila Resource to Identify Key Functional Interactions Between SARS-CoV-2 Factors and Host Proteins
Guichard et al., Cell Reports. 2023.
https://pubmed.ncbi.nlm.nih.gov/37480566/
To address how interactions between SARS-CoV-2 factors and host proteins affect COVID-19 symptoms, including long COVID, and facilitate developing effective therapies against SARS-CoV-2 infections, researchers reported the generation of a comprehensive set of resources, mainly genetic stocks and a human cDNA library, for studying viral–host interactions in Drosophila. Researchers further demonstrated the utility of these resources and showed that the interaction between NSP8, a SARS-CoV-2 factor, and ATE1 arginyltransferase, a host factor, causes actin arginylation and cytoskeleton disorganization, which may be relevant to several pathogenesis processes (e.g., coagulation, cardiac inflammation, fibrosis, neural damage).

PIKFYVE Inhibition Mitigates Disease in Models of Diverse Forms of ALS
Hung et al., Cell . 2023.
https://doi.org/10.1016/j.cell.2023.01.005
Investigators showed that pharmacological suppression of PIKFYVE activity reduces pathology and extends survival of animal models and patient-derived motor neurons representing diverse forms of amyotrophic lateral sclerosis (ALS). Upon PIKFYVE inhibition, exocytosis is activated to transport aggregation-prone proteins out of the cells, a process that does not require stimulating macroautophagy or the ubiquitin-proteosome system. These findings suggest therapeutic potential to manage multiple forms of ALS. Supported by ORIP (S10OD021553) and NINDS.
