Abstract: Foot-and-mouth disease (FMD) is an acute, hot, and highly contagious infectious disease caused by foot-and-mouth disease virus (FMDV) infection of cloven-hoofed animals. FMDV has seven serotypes and it spreads rapidly, which seriously affects the development of animal husbandry. FMDV is the prototype member of the Aphthovirus genus within the Picornaviridae family, and its genome encodes 4 structural proteins and 10 non-structural proteins. After infecting the host, FMDV uses its proteins to affect the host innate immune response through a variety of pathways and methods, which is beneficial to the microenvironment of FMDV replication. These strategies include FMDV involvement in autophagy, endoplasmic reticulum stress and stress granule formation of cellular processes, subverting the functions of various host proteins, such as hijacking, cleaving host proteins or interfering with the expression of host proteins, removing ubiquitin from host proteins, and inhibiting the phosphorylation of host proteins, which are also the focus of current research. Based on the existing research results, we summarized the research progress of FMDV protein in suppressing the innate immunity of host in recent years, intending to provide a reference for the research and prevention of FMDV.
