Viral infected cells

"Viral infected cells" refers broadly to any **host cell** (bacterial, archaeal, or eukaryotic) that has been entered and is exploited by a virus for replication and assembly of new virions. Viral infected cells serve as factories for viral genome replication and protein synthesis, often resulting in altered gene expression profiles, activation of programmed cell death pathways (apoptosis, necroptosis, pyroptosis), and triggering of innate and adaptive immune responses[2][7]. This term is not a molecular entity but rather a biological state; it does not conform to standardized molecular target nomenclature, and should not be used as a canonical drug target or receptor descriptor. Instead, therapeutic targeting in virology generally focuses on specific viral proteins, host entry receptors, or defined molecules involved in infection biology[3][4][5][6][7]. In summary, "viral infected cells" is not a canonical target (such as a protein, receptor, or gene) but rather a generic, unspecific reference to a large, functionally diverse group of cells in a pathophysiological state.
