Infectious diseases account for a large proportion of global health emergencies and are rising more so owing to the paucity of effective vaccination and chemotherapeutic strategies. The severity is compounded by the development of antibiotic resistance among major pathogenic strains, capable of residing in the hostile host microenvironment by hijacking its signaling mechanisms and molecular circuitry. Among such processes, studies on epidermal growth factor receptor (EGFR) have revealed specific contributions of this classical oncogenic signaling axis during distinct infection conditions. Here, we review the current status of EGFR family members in the context of host-pathogen interactions and speculate the possible dimensions of exploration and manipulation of the EGFR pathway for host-directed therapeutic purposes.
