Abstract: The major histocompatibility complex (MHC) class Ⅰ molecules,also known as swine leukocyte antigen (SLA) class Ⅰ molecules,play an important role in antigen presentation,organ transplantation,immune response and regulation.Cytotoxic T lymphocyte (CTL) epitopes are linear peptides that bind and present SLA-Ⅰ molecules after antigen processing by antigen-presenting cells.With high specificity,CTL epitopes play a key role in antigen recognition and presentation and cellular immunity against viral infection.CTL epitopes can stimulate CTLs to play the role of cell killing,which is mainly manifested as killing virus.The author reviewed the current status of CTL epitopes of several important porcine viruses,such as Foot-and-mouth disease virus,African swine fever virus and Porcine reproductive and respiratory syndrome virus,and analyzed the binding motif characteristics of SLA-Ⅰ and CTL epitopes by bioinformatics,in order to provide a reference for studying CTL epitopes derived from porcine viruses and designing the epitope vaccine in future.

Key words: cytotoxic T lymphocyte (CTL) epitopes; Porcine foot-and-mouth disease virus; African swine fever virus; Porcine reproductive and respiratory syndrome virus
