Article Abstract
Defective interfering particles (DIPs), derived naturally from viral particles, are not able to replicate on their own. Several studies indicate that DIPs exert antiviral effects via multiple mechanisms. DIPs are able to activate immune responses and suppress virus replication cycles, such as competing for viral replication products, impeding the packaging, release and invasion of viruses. Other studies show that DIPs can be used as a vaccine against viral infection. Moreover, DIPs/DI genomes display antitumor effects by inducing tumor cell apoptosis and promoting dendritic cell maturation. With genetic modified techniques, it is possible to improve its safety against both viruses and tumors. In this review, a comprehensive discussion on the effects exerted by DIPs is provided. We further highlight the clinical significance of DIPs and propose that DIPs can open up a new platform for antiviral and antitumor therapies.

Oncolytic virotherapy (OVT) has emerged as a promising and innovative cancer treatment strategy that harnesses engineered viruses to selectively infect, replicate within, and destroys malignant cells while sparing healthy tissues. Beyond direct oncolysis, oncolytic viruses (OVs) exploit tumor-specific metabolic, antiviral, and immunological vulnerabilities to reshape the tumor microenvironment (TME) and initiate systemic antitumor immunity. Despite promising results from preclinical and clinical studies, several barriers, including inefficient intratumoral virus delivery, immune clearance, and tumor heterogeneity, continue to limit the therapeutic advantages of OVT as a standalone modality and hindered its clinical success.

This review article presents an overview of the structure-function characteristics and extensive applications of complexes formed between lactoferrin (Lf) and various bioactive compounds. Lactoferrin, a glycoprotein predominantly found in colostrum, possesses iron-binding capacity and exhibits a wide range of biological activities, including antibacterial, antiviral, antifungal, antiparasitic, anti-inflammatory, anticancer, and antitumor effects. Through complexation with proteins, phenolic compounds, polysaccharides, and other bioactive substances, the structural and functional properties of Lf are significantly improved, enhancing its potential applications in the food, pharmaceutical, cosmetic, and industrial sectors.

Leukemia is a malignant clonal disease originating from hematopoietic stem cells, whose complex pathogenesis is associated with multiple factors. Epigenetic regulation has been found to play an important role in the occurrence and development of leukemia, and has become a major focus of research. Fucoidan (FPS), a natural sulfated polysaccharide primarily extracted from marine brown algae, is rich in L‑fucose and sulfate groups.
