In the published article, there was an error in positions of figures as published. Due to an oversight during the proofreading stage, Figure 2 and Figure 3 were swapped in the published version, resulting in a mismatch between the figure and their actual content. The corrected positions of figures and captions appear below.

Figure 2.

Diagram showing IFN stimulation and viral persistence promotion. On the left, interferon (IFN) activates RLR signaling, leading to MAVS activation and Type I/III interferon production. On the right, TNF binds to TNFR2, promoting TNF, TNFR2, and TRAF1 expression, and signaling via TNFR1 for cell survival. The nucleus contains standard viral genomes and DVG/DI-genomes.

High concentrations of DVGs significantly enhance type I/III interferon signaling by detecting and activating RIG-I-like receptors and MAVS signaling pathways. DVGs-rich cells activate the cell survival pathway by up-regulating TNF/TNFR2/TRAF1, and combine with a small amount of standard viral genome to maintain a persistent infection state.

Figure 3.

Diagram illustrating the immune response in an epithelium cell. A virus enters the cell, leading to RIG-I and MDA-5 activation, triggering RLR signaling. This results in the production of Type I IFNs and proinflammatory cytokines (TNF-α, IL-6, IL-12). Immature dendritic cells (DCs) mature and interact with Naive T Cells via MHC and TCR. B Cells and Th1 Cells are depicted, highlighting antibody, IFN-I, and cytokine involvement.

Schematic diagram of how DIPs activate host immune defense. DVGs are present in DIPs. Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated protein 5 (MDA-5) recognize copyback DVGs and then trigger the creation of interferons (IFNs) and other cytokines, which supports the activation of the innate immune response. These factors contribute to the maturation of dendritic cells, thus contributing to the adaptive immune response. Subsequently, DVGs can enhance the recognition between naive T cells and mature dendritic cells, promoting the cell-mediated immune process mediated by type I IFN signaling. This, in turn, stimulates B cells to produce corresponding antibodies, thereby exerting the function of humoral immunity.
