En présence de surplus d’énergie, les cellules synthétisent des lipides neutres dans la bicouche du réticulum endoplasmique (RE). Ils démixent ensuite pour former de nouvelles organelles, les corps lipidiques (CLs), qui émergent principalement dans le cytoplasme et régulent le métabolisme énergétique et de nombreux processus cellulaires. Cette thèse étudie les mécanismes de cette biogénèse directionnelle des CLs à l’aide de la physique des émulsions. Pour cela, nous avons développé un système in vitro reproduisant la topologie des CLs en formation et avons montré que le comportement du CL dans une membrane était régi par un équilibre de tension de surface comme dans un système de mouillage à trois phases. La directionnalité de l’émergence ...
