Great news reported today from two of my #portfolio companies: $KYMR (+107% over the last 6 months) and $DYN (+63% same period). Stocks are trading well on strong clinical redouts, with public markets now rewarding good data. You can own stocks into clinical catalysts and be compensated for it

Netflix agrees to buy Warner Bros. and HBO Max, creating streaming titan If approved by Trump administration regulators, the deal would lead to a new entertainment and technology behemoth.

Netflix to acquire Warner Bros Discovery for $82.7 billion. The main jewels are Warner’s film and television studios, HBO Max and HBO

This deal has clearly nothing to do with biopharma, but we all love Game of Thrones, Succession, Friends etc. Happy Friday everyone!

His discoveries deeply influenced my decision to pursue my PhD at @crg.eu on stem cell biology and cell fate conversions. Years later I was fortunate enough to briefly meet him at an @isscr.org Annual meeting, a true honor as I got to meet one of the great legends of modern developmental biology

Nobel Laureate Professor Sir John Gurdon dies aged 92 It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the Gurdon Institute.

Today is a very sad day. Sir John Gurdon was a titan of developmental biology. Gurdon’s foundational research, culminating in his Nobel Prize recognition in 2012, was a great source of inspiration to me as a university student at the time

Great recognition to a fundamental discovery that reshaped modern #immunology. Congrats to the laureates!

However, imho the Nobel committee missed the chance to acknowledge an additional key contributor to the understanding of #Foxp3 and #Treg functionality

Cancer cell plasticity defines response to immunotherapy in cutaneous squamous cell carcinoma - Nature Communications Immune surveillance is critical to prevent the development and progression of cutaneous squamous cell carcinoma (cSCC). Here, the authors show that epithelial-mesenchymal plasticity in cancer cells is associated with changes in their immune checkpoint ligand profile during mouse cSCC progression, which dictates differential responses to immune checkpoint blockade.

This study by @lauralorenzos.bsky.social in @natcomms.nature.com is particularly relevant > expression of immune checkpoint ligands shifts between epithelial & mesenchymal tumors, suggesting combo ICB strategies are needed for treating hybrid EMT & mesenchymal tumors

Identification, functional insights and therapeutic targeting of EMT tumour states - Nature Reviews Cancer In this Review, Dong and Blanpain outline our current understanding of the epithelial-to-mesenchymal transition in cancer, which we now know is not a simple binary switch but the existence of a series of different tumour states. The authors also discuss the implications of this knowledge for pharmacologically targeting epithelial-to-mesenchymal transition to overcome therapy resistance.

Elegant piece by @cedric-blanpain.bsky.social in @natrevcancer.nature.com especially highlighting the recent advances of potential #therapeutic strategies to target #EMT tumor states
