Abstract
A recent study published in Nature Communications showed that essential modulatory roles of interfacial adhesion and mechanical microenvironments such as geometric constraints and extracellular matrix stiffness, in microbe-host cell interactions. This study utilized single-cell force spectroscopy and RNA sequencing to gain insight into the intrinsic mechanisms by which the mechanical microenvironment regulates bacterial-host interactions and therefore reveal potential interventions against bacterial invasion. Meanwhile, the adhesion forces involved in the bacterial-host interactions were recognized as a new indicator for assessing the extent of bacterial infection. Taken together, these findings demonstrate that interfacial adhesion forces and mechanical microenvironments play a dominant role in modulating functions and behaviors of microorganisms and host cells, which also provide a mechanobiology-inspired idea for the development of subsequent drug-resistant antimicrobials and broad-spectrum antiviral drugs.
