This 2024 study reveals that boosting cGMP with drugs like tadalafil or CYR119 improves proteostasis, myelination, and nerve conduction in mouse models of #CMT1A & #CMT1B. Promising steps toward potential treatments! link.springer.com/article/10.100…

Interesting targeting approach: Antibody-targeted chromatin delivers CRISPR/Cas9 efficiently into cells. High precision, low toxicity, and no viral components. Could this be applicable to CMT1A? academic.oup.com/nar/article/47…

Fascinating treatment for SMA 👇 EVRYSDI is a small molecule taken daily. It modifies SMN2 gene splicing by binding to SMN2 mRNA and results in increasing the production of the life-saving SMN protein. Wondering if it could be engineered to bind to PMP22 mRNA…

academic.oup.com/brain/article/… Boosting cGMP levels with sildenafil restores proteasome function, reduces proteotoxic stress, & improves myelination in a mouse model of CMT1B. This could also work for CMT1A.

onlinelibrary.wiley.com/doi/abs/10.100… This paper shows that we can measure a 1.55x increase in PMP22 from CMT1A skin biopsies. This implies that skin biopsies can be used to accurately measure a (future) treatment's ability to downregulate the body's production of PMP22.

ncbi.nlm.nih.gov/pmc/articles/P… Excessive PMP22 disrupts the delicate balance of lipid-to-protein ratio required for proper myelin structure. This imbalance leads to the formation of disordered myelin-like assemblies, contributing to the defective myelin in CMT1A.
