We show that human myxovirus resistance protein 1 (MxA) suppresses replication of highly pathogenic avian influenza A(H5N1) viruses isolated from mammals in vitro and MxA-transgenic mice. However, H5N1 can evade MxA restriction through replacement individual viral polymerase complex components a human-adapted MxA-resistant strain vitro.

Although the overall number of Europe has not been this low since 2019–2020 epidemiological year, HPAI viruses continue to circulate at a very level.

Ecological systems are complex. Representing heterogeneous knowledge about ecological is a pervasive challenge because data generated from many subdisciplines, exist in disparate sources, and only capture subset of interactions underpinning system dynamics. Knowledge graphs (KGs) have been successfully applied to organize predict new linkages complex systems. Though not previously broadly ecology, KGs much offer an era when dynamics responding rapid changes across multiple scales. We developed KG demonstrate the method's utility for problems focused on highly pathogenic avian influenza (HPAI), transmissible virus with broad host range, wide geographic distribution, evolution pandemic potential. describe development graph include related HPAI including pathogen-host associations, species distributions, population demographics, using semantic ontology that defines relationships within between datasets. use perform set proof-of-concept analyses validating method identifying patterns ecology. underscore generalizable value ecology ability reveal known testable hypotheses support deeper mechanistic understanding The code available under MIT License GitHub at https://github.com/cghss-data-lab/uga-pipp.
