Viral infection mechanism and the entire process of host immune response

This template comprehensively demonstrates the viral infection life cycle and host cell interaction mechanisms, covering key steps such as viral entry (receptor-mediated endocytosis), genome release, replication and assembly (dependent on host organelles), and progeny viral release (budding or lysis). It also details the host's innate immune response (such as interferon signaling and NK cell activation), adaptive immune activation (T/B cell-specific recognition), and immune escape strategies (viral protein interference with MHC presentation). It also links clinical pathology (acute infection, latent infection, and chronicity) and antiviral therapeutic targets (such as polymerase inhibitors). This template is suitable for microbiology teaching, immunology research, vaccine development, and infectious disease prevention and control advocacy, with scientifically rigorous content that adheres to pathogenic biology standards.
