Liquid-liquid phase separation (LLPS) is a biomolecular process in which different biomolecules, such as proteins and nucleic acids, form liquid condensates through interactions, and these condensates play key roles in cellular physiological processes. LLPS may affect the development of sepsis through several pathways, such as modulation of inflammatory factors, immune responses, and cell death, by altering the function or activity of biomolecules, which, in turn, affect the cellular response to infection and inflammation. In this paper, we first discuss the mechanism of phase separation, then summarize the studies of LLPS in sepsis, and finally propose the potential application of LLPS in sepsis treatment strategies, while pointing out the limitations of the existing studies and the directions for future research.Keywords: biomolecular condensate, cGAS-STING, liquid-liquid phase separation, sepsis, inflammatory response |
