Research progress in visualization reporter systems for influenza virus

Abstract:

The continuous evolution and drug-resistant mutations of influenza virus have placed higher demands on the study of its pathogenic mechanism, as well as the development of antiviral drugs and vaccines. As a key tool for real-time monitoring of viral infection, replication and transmission, viral visualization reporter systems have evolved into various strategies, including high-resolution microscopic imaging, exogenous nanomaterial labeling, recombinant reporter viruses, and virus infection-inducible reporter systems. This manuscript systematically reviewed the research progress of influenza virus visualization technologies, elaborated the principles, core breakthroughs, and application scenarios of each technique, analyzed the common limitations and specific problems existing in the current technical system, and prospected its development direction combined with cutting-edge research, providing a reference for technical selection and innovative applications in influenza virus visualization research.
