Abstract A central challenge in infection medicine is to determine the structure and function of host-pathogen protein-protein interactions to understand how these interactions facilitate bacterial adhesion dissemination and survival. In this review we focus on proteomics electron cryo-microscopy and structural modeling to showcase instances where affinity-purification AP and cross-linking XL mass spectrometry MS has advanced our understanding of host-pathogen interactions. We highlight cases where XL-MS in combination with structural modeling has provided insight into the quaternary structure of interspecies protein complexes. We further exemplify how electron cryo-tomography has been used to visualize bacterial-human interactions during attachment and infection. Lastly we discuss how AP-MS XL-MS and electron cryo-microscopy and -tomography together with structural modeling approaches can be used in future studies to broaden our knowledge regarding the function dynamics and evolution of such interactions. This knowledge will be of relevance for future drug and vaccine development programs.
