Porcine adaptive immune system

The porcine adaptive immune system is a sophisticated biological network in swine (Sus scrofa) responsible for providing pathogen-specific defense and long-term immunological memory (Lunney et al., 2016, Annual Review of Animal Biosciences). It comprises specialized cells, primarily T and B lymphocytes, and molecular components such as the Swine Leukocyte Antigen (SLA) complex and various immunoglobulins. Unlike the innate immune system, the adaptive system relies on somatic recombination to generate a diverse repertoire of antigen receptors, allowing for the recognition of specific viral, bacterial, and parasitic epitopes (Hammer et al., 2020, Frontiers in Immunology). In veterinary medicine, this system is the primary target for vaccine strategies aimed at controlling major agricultural diseases like Porcine Reproductive and Respiratory Syndrome (PRRS) and Swine Influenza. Furthermore, the porcine adaptive immune system is a critical area of study in xenotransplantation, as the immunological hurdles between pigs and humans must be overcome to allow for successful organ grafting (Cooper et al., 2019, BMC Medicine). Understanding its unique features, such as the high frequency of CD4/CD8 double-positive T cells, is essential for developing effective porcine-specific immunotherapies and vaccines (Saalmüller et al., 2002, Veterinary Immunology and Immunopathology).
