Article Abstract
African swine fever virus (ASFV), the causative agent of African swine fever (ASF), poses a catastrophic threat to global swine industries through its capacity for immune subversion and rapid evolution. Multigene family genes (MGFs)-encoded proteins serve as molecular hubs governing viral evolution, immune evasion, cell tropism, and disease pathogenesis. This review synthesizes structural and functional evidence demonstrating that MGFs-encoded proteins suppress both interferon signaling and inflammasome activation, while their genomic plasticity in variable terminal regions drives strain diversification and adaptation. Translationally, targeted deletion of immunomodulatory MGFs enables the rational design of live attenuated vaccines that improve protective efficacy while minimizing residual virulence. Moreover, hypervariable MGFs provide strain-specific signatures for PCR-based diagnostics and phylogeographic tracking, directly addressing outbreak surveillance challenges. By unifying virology with translational innovation, this review establishes MGFs as priority targets for next-generation ASF countermeasures.

African swine fever virus (ASFV) encodes multiple proteins to achieve immune escape, thereby disrupting the host's antiviral defense. This study demonstrates that the ASFV-encoded pE248R protein disrupted the Retinoic Acid-Inducible Gene I (RIG-I) mediated antiviral signaling cascade through dual regulatory mechanisms. Mechanistically, pE248R interacted with the caspase activation and recruitment domains (CARD) of RIG-I, effectively blocking its interaction with the mitochondrial adaptor MAVS.

Overwhelming proinflammatory responses are a major virulence mechanism for ASFV, but the dynamics of these changes during clinical disease are not completely understood. We constructed a detailed portrait of the innate immune responses during acute African swine fever (ASF) at the cellular, transcriptomic, and cytokine levels.

In September 2023, Sweden experienced its first ever outbreak of African swine fever (ASF). One year later, in September 2024, Sweden was declared free from ASF. One of the first actions taken toward control and eradication was an intensive search for wild boar carcasses.

African swine fever (ASF) is a hemorrhagic disease of domestic pigs and wild boars. The ASF virus (ASFV), a sole member of the family Asfarviridae and genus , causes this devastating disease. In sub-Saharan Africa, ASFV is maintained through three interlinked cycles: the domestic cycle, the pig-tick cycle, and the sylvatic cycle, which collectively sustain its endemic presence in the region.

Lipid profile of spleen and bursa of Fabricius (BF) during acute infection remains unknown. Acute infection models of porcine reproductive and respiratory syndrome virus (PRRSV), porcine epidemic diarrhea virus (PEDV) and Eimeria tenella (ET) were developed, and spleen samples with African swine fever virus (ASFV) or not were collected. Spleen and BF were examined and characteristic microscopic lesions were observed.
