This first edition, which focused on the theme of “Tumors and Microenvironment Heterogeneity,” took place at the Palais du Pharo on December 8.

More than just a scientific meeting, this first edition marks the beginning of a strengthened dynamic between our two institutes. Discussions about ongoing projects, presentations of platforms, and informal conversations have already led to new avenues to explore together in the future.

The keynote speaker Joshua Waterfall (Institut Curie), who came to share his expertise, also contributed to these discussions and opened up interesting perspectives for our work in immunology and oncology.

Poster Awards: Congratulations to Yann Groult (CIML) and Chloé Terrier (CRCM), whose presentations stood out in a particularly rich session.

We would like to thank the organising committee, Emilie Mamessier, Achille Broggi, Toby Lawrence, Michel Aurrand-Lions, Noushin Mossadegh-Keller, Rodolphe Moreau, Anita Dumenil and Maëlle Picard, for their coordination, which has enabled us to embark on this new chapter of collaboration.

We would also like to thank Le Palais du Pharo and Aix-Marseille University for their hospitality.
