🔚 Bottom line:
SAS induces a context-dependent innate immune memory that enhances protection but is reversible.
This opens doors to smarter vaccine design using adjuvants as immune trainers.

Challenge Specific Modulation of Responses to Adjuvant‐Induced Innate Immune Memory
We utilised a commercially available adjuvant formulation to study the induction, maintenance, and consequences of innate immune memory. Using functional assays on bone marrow-derived innate cells, e...

📊 Bone marrow single-cell transcriptomic (scRNAseq) analyses revealed:

-Upregulation of immune genes (e.g. Elane, Gzmb, Fc receptors)
-Downregulation of epigenetic regulators and metabolic genes
→ A shift toward immune activation and metabolic rewiring.

🧬 SAS-trained mice showed:

-Reduced proinflammatory TNF production by macrophages
-Increased circulating monocytes and altered HSPC population dynamics
-Enhanced neutrophil antimicrobial activity

This suggests functional reprogramming of innate cells.

💉 We used the Sigma Adjuvant System (SAS), which contains MPLA (TLR4 agonist) and TDCM (MINCLE agonist).
We treated mice and tracked long-term changes in bone marrow hematopoietic stem and progenitor cells (HSPCs).

Result: SAS shifted HSPC populations toward myeloid-biased progenitors.

Muchas gracias a la organización del evento, a Hika Ateneo por el espacio, y a todas aquellas personas que se acercaron a conocer un poco más nuestros proyectos de investigación. ¡Espero que disfrutaran y aprendieran tanto como yo!

¡Nos vemos el año que viene en los bares!

Esta charla se enmarca dentro de "Pint of Science", un festival internacional de divulgación científica en el que me hace mucha ilusión participar, especialmente siendo el décimo aniversario. ¡Gracias @pintofscience.es y al equipo organizador de Bilbo por la oportunidad!
