Genetic material transfer via viral entry

Genetic material transfer via viral entry denotes the process by which viruses attach to host cell receptors and undergo membrane fusion or penetration to deliver their genetic material (DNA or RNA) into host cells[3][4][6]. This process is crucial both for natural viral infection and gene therapy using viral vectors. In viral gene therapy, engineered viruses (viral vectors) are used to efficiently transport therapeutic genes into target cells, though safety challenges such as immune activation and possible integration of vector DNA remain[1][4]. The underlying cellular mechanisms include receptor-mediated endocytosis, fusion with cellular membranes, and evasion of lysosomal degradation[3][5][6]. While inhibitors against specific steps or proteins involved in viral entry are used therapeutically (e.g., fusion inhibitors, receptor antagonists), the process itself does not represent a direct molecular target suitable for standard drug target annotation frameworks[3][6].
