Abstract
The pivotal involvement of the host immune system in cancer therapy has dramatically reshaped therapeutic paradigms, inaugurating the era of immunotherapy. Nonetheless, antigen-specific immunotherapies encounter substantial hurdles within the highly immunosuppressive microenvironment of glioblastoma (GBM), which thwarts antitumor T-cell immunity. Oncolytic viruses (OVs), a form of immunotherapy that inflames the GBM microenvironment, have been subject to clinical evaluation, yielding promising outcomes. Evidence increasingly indicates that OVs can modify the GBM microenvironment from an immunosuppressive to an immune active state, facilitating enhanced antitumor responses. Clinical trials demonstrate that oncolytic virotherapy is generally well-tolerated, generating data about its immune-activating effects. "Window of opportunity" trials provide insights into viral replication, pre-existing immunity, and delivery methods. However, constraints in post-treatment sampling may impede comprehensive analyses of the virotherapy-induced biological and immunological changes. This review discusses current advancements and persistent challenges in GBM trials involving OVs.
期刊介绍:
Seminars in Immunology is a specialized review journal that serves as a valuable resource for scientists in the field of immunology. The journal's approach is thematic, with each issue dedicated to a specific topic of significant interest to immunologists. It covers a wide range of research areas, from the molecular and cellular foundations of the immune response to the potential for its manipulation, highlighting recent advancements in these areas.
Each thematic issue is curated by a guest editor, who is recognized as an expert in the field internationally. The content of each issue typically includes six to eight authoritative invited reviews, which delve into various aspects of the chosen topic. The goal of these reviews is to provide a comprehensive, coherent, and engaging overview of the subject matter, ensuring that the information is presented in a timely manner to maintain its relevance.
The journal's commitment to quality and timeliness is further supported by its inclusion in the Scopus database, which is a leading abstract and citation database of peer-reviewed literature. Being indexed in Scopus helps to ensure that the journal's content is accessible to a broad audience of researchers and professionals in immunology and related fields.
