ABSTRACT
Biomolecular condensates are membraneless organelles formed through liquid-liquid phase separation. Innate immunity is essential to host defense against infections, but pathogens also harbor sophisticated mechanisms to evade host defense. The formation of biomolecular condensates emerges as a key biophysical mechanism in host-pathogen interactions, playing pivotal roles in regulating immune responses and pathogen life cycles within the host. In this review we summarize recent advances in our understanding of how biomolecular condensates remodel membrane-bound organelles, influence infection-induced cell death, and are hijacked by pathogens for survival, as well as how they modulate mammalian innate immunity. We discuss the implications of dysregulated formation of biomolecular condensates during host-pathogen interactions and infectious diseases and propose future directions for developing potential treatments against such infections.
