Viral envelopes, proteins, nucleic acids, and host cell membranes

The collective term 'Viral envelopes, proteins, nucleic acids, and host cell membranes' refers to the essential structural and functional components required for the viral life cycle and pathogenesis. Viral envelopes are host-derived lipid bilayers embedded with viral glycoproteins that facilitate attachment and fusion with target host cells [1]. Within the virus, proteins serve as structural capsids or functional enzymes, such as polymerases and proteases, which drive the replication of viral nucleic acids (DNA or RNA) [2]. Host cell membranes provide the necessary receptor landscape, such as ACE2 or CD4, which viruses exploit to gain entry into the cytoplasm [3]. Antiviral therapies target these components by inhibiting specific stages of infection, including viral docking, genome synthesis, or the maturation of new virions [4]. Because this entry encompasses a vast array of distinct biological entities across diverse virus families, it is categorized as a broad conceptual group rather than a single specific therapeutic target [5].
