Their ability to establish infection and cause disease is critically dependent on successfully subverting the host's innate immune defenses, particularly the Type I Interferon (IFN\u2010I) system. This review provides a comparative analysis of the molecular strategies employed by CHIKV, VEEV, and SINV to dismantle these antiviral pathways. We first outline the conserved principles that form a core alphavirus \u201ctoolkit\u201d for evasion, such as the formation of membrane\u2010bound replication factories to shield viral RNA from cytosolic sensors and NSP1\u2010mediated mRNA capping to mimic host transcripts. The review then delves into the divergent, virus\u2010specific tactics, highlighting the central role of the non\u2010structural protein 2 (NSP2) as a master antagonist. We contrast the aggressive strategies of pathogenic alphaviruses\u2014such as CHIKV NSP2\u2010mediated cleavage of MAVS and degradation of STAT2, and VEEV\u2010induced degradation of STAT1\u2014with the more subtle, modulatory approach of SINV, which relies more on a global shutdown of host gene expression. These distinct molecular mechanisms are directly correlated with their varying pathogenic outcomes. Furthermore, we examine the remarkable adaptability of these strategies between vertebrate hosts, where suppressing the IFN system is paramount, and invertebrate vectors, where evading the RNAi pathway is the primary challenge. A comprehensive understanding of these commonalities and divergences in immune evasion is essential for the rational design of broad\u2010spectrum antiviral therapeutics and next\u2010generation vaccines.<\/jats:p>","DOI":"10.1002\/rmv.70174","type":"journal-article","created":{"date-parts":[[2026,6,6]],"date-time":"2026-06-06T19:18:27Z","timestamp":1780773507000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pathogen\u2010Specific
