Most of my posts are long — maybe too long. The charitable explanation is that I can’t resist my instincts as a professor to explain stuff so my learners can understand it. The less charitable explanation is that I’m just a windbag. So here are a bunch of very brief items of news, ideas and opinion about PSP and CBD in the style of Twitter. In fact, I’ll even limit my character count to 280, including spaces. Here goes.
A group in Bologna did skin biopsies to look for a phosphorylated form of α-synuclein in PD, PSP or CBD, and controls – 26 subjects in each group. They found it in all 26 with PD, in no controls, and in 24 with PSP/CBD. (The other two had PD-like features.) Now: how about MSA?
You’ve noticed that CurePSP’s publicity materials call PSP, CBD and MSA “prime of life” diseases because those conditions’ usual decades, the 50s, 60s and 70s, are when life can otherwise be lived to the fullest. Do you agree? Let me know.
A group called the PSP Research Roundtable was formed in 2017 to help speed the process of testing promising drugs. It’s run by CurePSP and has membership from academia, the FDA, the NIH, drug companies, biotech, philanthropy and patient advocacy groups.
Transposon Therapeutics has started a Phase 2 trial of TPN-101 in PSP at private clinical trial sites in Boca Raton, FL and Farmington Hills, MI. Like many available HIV drugs, TPN-101 inhibits the enzyme reverse transcriptase, but otherwise, details are sparse.
About the mechanism of action of TPN-101: I can tell you that another reverse transcriptase inhibitor routinely used for HIV called efavirenz (trade names Sustiva and Stocrin) reduces tau aggregation. CurePSP is currently supporting a study of it in a mouse tauopathy model in The Netherlands.
Enough for now. No windbag, I.
