Adenovirus-associated cell lysis Overview
Adenovirus-associated cell lysis refers to the destruction of host cells following adenoviral infection. This process involves several molecular pathways, including induction of autophagy, activation of caspases (notably via the extrinsic FADD/caspase 8 pathway), and physical disruption of cellular and endosomal membranes through viral proteins such as protein VI and Adenovirus Death Protein (ADP)[1][2][3][4]. In the context of oncolytic therapy, engineered adenoviruses exploit lytic cell death to kill cancer cells and release viral progeny. While not a molecular target or receptor, key proteins involved in adenovirus-associated lysis (e.g., ADP, autophagy regulators) are active areas of research for modulating these pathways in therapy[1][4].
Mechanism of Action
Induction of autophagy and caspase activation, leading to cell lysis[1]\nDisruption of endosomal membranes by structural proteins (e.g., protein VI)[2][3]\nViral gene products such as Adenovirus Death Protein (ADP) accelerate host cell lysis in late infection[4]
Biological Functions
Disease Associations
Safety Considerations
- Off-target cell death in non-cancerous tissues (for oncolytic therapies)
- Immune response/inflammation from viral lysis
