Happy to end 2025 by sharing a review we wrote on a dichotomy that fascinates me: are cryptic proteins mostly rapidly degraded to generate MHC antigens, or do they give rise to evolutionarily recent proteins testing new functions? The answer: probably both. onlinelibrary.wiley.com/doi/10.1002/...
onlinelibrary.wiley.com
Decoding the Cryptic Proteome Between Antigens and Novel Functional Proteins
Unannotated splicing and translation of non-canonical open reading frames generate a diverse repertoire of cryptic proteins. Most are rapidly degraded, rendering them possible MHC-I substrates. Yet, ....

🚨🚨🚨 New review article on #microexons from the lab! A comprehensive recap of the current state of the field by @tahneema.bsky.social. www.annualreviews.org/content/jour...
Network plot with microexon-associated phenotypes (nodes shown in dark gray). Microexon nodes are colored by exon length, and node size represents the level of conservation to the LCA as given in VastDB (109): human specific, Euarchontoglires (conserved from human to mouse and/or rat), Eutheria (to cow), Amniota (to chicken), Euteleostomi (to zebrafish), and Bilateria (to fruit fly).

Many transcriptome regions are translated but not known to encode proteins. They remain poorly annotated and thus under studied, partly due to the lack of terminology for these features. In @natmethods.nature.com we propose using "Translon" for any region decoded by the ribosome

"The main fates after gene duplication are gene loss, redundancy, subfunctionalization and neofunctionalization". In our new review, @fedemantica.bsky.social and I argue we are missing the most prevalent one: specialization. And the same applies to alternative splicing! 1/7 tinyurl.com/45k7kbmp

1/ We saw an update on the PDAC neoantigen vaccine (Sethna et al., 2025). A remarkable effort in showing long-lived T cell protection in PDAC + an exhaustive look at the T cells. One question intrigued me: Were the selected neoantigens different between the 8 responder and 8 non-responder patients?

Top 4 things to know about doing science: 1. You need to have someone you can talk to 2. One-on-one discussions are the best 3. Think about discussions as improvisations and use the ‘yes, and’ rule 4. Create a safe space so both of you feel open to saying seemingly silly things

The last Cell issue of the year is online. This one is a doozy if you like interferons (as I do!) or transposons and ERVs (and who doesn't?!) There's also cool stem cell and dev bio in this issue, immune responses to Zika during pregnancy... cancer, plants... cool stuff! www.cell.com/cell/issue?p...
Cover art for the December 26, 2024 issue of the journal Cell. The artwork resembles spilled and swirled paint, with bright colors of pink, yellow, green, white, and black on a deep blue background. The "Cell" logo appears in bold white text in the upper left corner and the Cell Press 50th anniversary logo appears in light blue text in the bottom right corner. Taken from the published cover description: "The cover image features an artistic representation of how the fetal tripotent pancreatic stem cell (pink, yellow, and white smaller circle) gives rise to the three main cell lineages of the pancreas (pink, yellow, and green fluid lines), which together make up the pancreas organ (yellow, green, and pink larger oval). Image resources: Simona Jole Anna Lafirenze."

The final chapter of my PhD thesis is now out! 🎉 We compared the latest gene regulatory network (#GRN) inference methods for #single-cell multimodal datasets and evaluated their performance across various tasks. Hard to believe this journey started in March 2021 and has finally reached this point 😅🥳

#NotOnlyParasites! 2 Cell papers by @edchuong.bsky.social lab & Amigorena lab demonstrate that transposable elements #TEs can exonize giving rise to functional (often shorter) proteins with distinct functions: eg a decoy short IFNAR2 that inhibits #interferon signaling! www.cell.com/cell/fulltex...

Transposable element exonization generates a reservoir of evolving and functional protein isoforms
Transposable element exonization by unannotated splicing events produces stable protein isoforms with acquired functions that are subject to evolutionary selection.

Not easy to describe the emotions of seeing our work published in @cellpress.bsky.social ! We explored how novel isoforms emerge during evolution through the exonization of Transposable Elements. Exonized TEs modify the functions and structures of host proteins. www.cell.com/cell/fulltex...
