TDP-43 dysfunction leads to the accumulation of cryptic transposable element-derived exons, crypTEs, in iPSC derived neurons and ALS/FTD patient tissues
TDP-43 is an RNA and DNA binding protein that plays major roles in regulating RNA processing. In particular, TDP-43 dysfunction leads to the accumulation of cryptic splice isoforms that result from im...

It is with profound sadness that I have learned of the passing of my beloved PhD supervisor, John Gurdon. We have lost a true giant, an incredible mentor, kind and generous, whose contributions to science will inspire generations. He changed my life, and the lives of so many others.

John Gurdon was a true giant:
- founder of cell reprogramming;
- founder of molecular embryology;
- unabashed advocate for basic research;
- advisor to numerous successful trainees/PIs;
- gentle human that touched so many.
In dark times with science under attack, let his vision be a guiding light.
Very saddened to hear of John Gurdon’s passing. I’ve been lucky enough to interact with him at multiple points through my career - from undergrad lectures, through his position as former Chair of @biologists.bsky.social’s Board of Directors, and as an author at @dev-journal.bsky.social.
