The UK Cellular microbiology network meetings were started in 2019 and are a must-attend for anyone working on host-pathogen interactions. With an emphasis on interactions at or within the host cell, this meeting will focus on how pathogens subvert host cellular processes and how the cell responds to invasion. The meeting will bring together the host-pathogen interaction community, particularly from the UK, to provide a network to foster collaboration and interchange across the various pathogens under study.
