01
Overview
The "virus replication process (host-directed)" refers to therapeutic strategies aimed at disrupting viral reproduction by interfering with essential—but non-vital—host functions exploited during infection. This approach targets cellular factors or pathways utilized by viruses, such as lipid metabolism, kinases, or immune response regulators, rather than directly attacking viral components. Host-directed antivirals offer potential advantages, including a lower likelihood of resistance development and broad-spectrum applicability, but require careful selection of targets to minimize off-target effects and the risk of viral adaptation.
