Background: Acute promyelocytic leukaemia (APL) is a clonal disease arising by hematopoietic stem cell (HSC), which characterized by inappropriate proliferation/differentiation or survival of immature myeloid progenitors. Oncolytic adenoviruses have been under widespread investigation as anticancer agents. Recently, our data suggested that tumor cells were cured by AdCN205-IL-24, an adenovirus serotype 5-based conditionally replicating adenovirus expressing IL-24 after infection.

Methods: In this study, we created a novel fiber chimeric oncolytic adenovirus AdCN306-IL-24 that has Ad11 tropism and approved CAR (coxsackie adenovirus receptor, CAR)-independent cell entry, which could allow development of selective cytopathic effects (CPE) in APL cells in vitro.

Results: Formidable cytotoxic effect was specifically implemented in APL cells after infection with AdCN306-IL-24. The expression of IL-24 was up-regulated upon treated with accepted tumors. And the vector also induced superior cytolytic effects activity in APL cells by activation of programmed cell death.

Conclusions: Taken together, our data suggested that chimeric oncolytic adenovirus AdCN306-IL-24 could express IL-24 gene, representing a potential therapeutics for acute promyelocytic leukemia.

Antibody-drug conjugates (ADCs) are increasingly used in clinic for multiple indications and may improve upon the activity of parental antibodies by delivering cytotoxic payloads into target cells. This activity is predicated upon internalization to release the cytotoxic payloads intracellularly. Since binding of ADCs to their cell surface targets does not guarantee their internalization, we hypothesize that proteolysis targeting chimeras (PROTACs) could improve the activity of ADCs through forced internalization.

Durable antitumor response via an oncolytic virus encoding decoy-resistant IL-18.

Article Synopsis
  • Interleukin-18 (IL-18) enhances immune responses, but its clinical use is limited by a decoy receptor; to overcome this, researchers developed a variant called DR18 that doesn't bind to IL-18 binding protein.
  • They tested this DR18 variant using an oncolytic adenovirus (oAdDR18) in mouse models of different tumors to see its effects on tumor growth and immune response.
  • Results showed that oAdDR18 led to significant tumor growth reduction and enhanced immune cell infiltration compared to other forms of IL-18, indicating strong potential for treating cancers and reducing metastasis.

Systemic administration of oncolytic viruses (OVs) is a promising approach for targeting metastatic solid tumors, but their anti-tumor activity is limited by pre-existing neutralizing antibodies against common human viruses. Therefore, investigators have developed OVs derived from non-human host viruses. Successful implementation of this strategy requires that the viral vector selectively infects and replicates within human cancer cells.

Bioorthogonal oncolytic-virus nanovesicles combined bio-immunotherapy with CAR-T cells for solid tumors.

Various oncolytic viruses (OVs) have been adopted as therapeutic tools to increase the efficacy of chimeric antigen receptor (CAR)-T cells against solid tumors. However, the therapeutic effect of OVs has been limited by pre-existing neutralizing antibodies and poor targeting delivery for systemic administration. Herein, we propose using bioorthogonal OV nanovesicles to boost the antitumor effects of CAR-T cells in solid tumors by reshaping the tumor microenvironment.

Glioblastoma (GBM), the most common and aggressive primary central nervous system (CNS) tumor in adults, continues to have a dismal prognosis. Across hundreds of clinical trials, few novel approaches have translated to clinical practice while survival has improved by only a few months over the past three decades. Randomized controlled trials of immune checkpoint inhibitors (ICIs), which have seen impressive success for advanced or metastatic extracranial solid tumors, have so far failed to demonstrate a clinical benefit for patients with GBM.
