Tumor cell infection machinery

The term "Tumor cell infection machinery" does not refer to a single molecular target, but rather encompasses the diverse set of surface receptors, endocytic pathways, and intracellular trafficking components that viruses or engineered vectors utilize to enter and infect malignant cells. In the context of oncolytic virotherapy, this machinery includes specific proteins such as the Coxsackievirus and Adenovirus Receptor (CAR), CD46, Nectin-4, and various integrins that are often overexpressed on the surface of cancer cells (Source: NIH, PMC4149123). These components are exploited to achieve tumor-selective delivery of genetic material or to induce direct viral oncolysis. Because this term describes a broad biological process involving multiple distinct proteins and pathways rather than a specific enzyme or receptor, it is considered a conceptual category rather than a canonical therapeutic target. Therapeutic strategies targeting this machinery focus on modifying viral tropism to enhance affinity for tumor-specific markers while minimizing entry into healthy cells (Source: Nature Reviews Cancer, 2021).
