Dendritic cell(DC)vaccine therapy has been widely studied as cancer immunotherapy that potently induces cytotoxic T lymphocytes. However, their efficacy in clinical practice has not yet been established. We have developed an oncolytic adenovirus OBP-702 carrying the tumor suppressor gene p53 and have demonstrated its therapeutic potential to induce cytopathic effect and activate antitumor immunity via p53 induction. In this study, we investigated the combined effect of p53-transduced DC vaccine and OBP-702 in colorectal cancer.

Melanoma is an aggressive malignancy originating from melanocytes, marked by its high metastatic potential, severe malignancy, and poor prognosis. The primary clinical approach involves surgical resection, complemented by adjuvant therapies such as radiotherapy, chemotherapy, targeted therapies, and immunotherapies. In recent years, high-dose IFNα2b has emerged as a pivotal adjuvant therapy following surgery.

Immune tolerance restricts the number of T cells with significant affinity for self-tumor-associated antigens (TAAs), thereby limiting successful cancer immunotherapy through an inability to generate populations of high-affinity anti-tumor T cells. In contrast, viral infection/vaccination primes and expands high-affinity effector and memory T cells against viral antigens. We show here that it is possible to exploit population-wide preexisting, anti-viral memory recall responses against SARS-CoV-2 antigens to focus a high-affinity, immunodominant T cell response into tumors by oncolytic virus (OV)-mediated or chimeric antigen receptor (CAR)-mediated delivery of viral antigens that are not themselves related to TAAs.

Among solid pediatric tumors, brain tumors are the leading cause of cancer-related mortality. While survival rates have improved for certain pediatric brain tumor subtypes, the overall prognosis remains poor. Consequently, there is an urgent need for novel therapies that are not only effective but also less toxic.

Background: Chimeric antigen receptor (CAR)-T cell therapy has shown success in hematologic malignancies but has encountered challenges in solid tumors. Macrophages, being a potentially effective therapeutic target, have led to the development of several therapeutic strategies due to their unique phagocytic function. This study aimed to develop an effective solid tumor immunotherapy strategy by combining CAR macrophages (CAR-Ms) targeting PD-L1 with CD47 antibody-armed oncolytic adenovirus (oAd-CD47).

Glioblastoma (GBM) remains one of the most aggressive and treatment-resistant brain tumors, necessitating novel therapeutic approaches. Oncolytic treatments, particularly oncolytic viruses (OVs), have emerged as promising candidates by selectively infecting and lysing tumor cells while stimulating anti-tumor immunity. Various virus-based therapies are under investigation, including genetically engineered herpes simplex virus (HSV), adenovirus, poliovirus, reovirus, vaccinia virus, measles virus, and Newcastle disease virus, each exploiting unique tumor-selective mechanisms.
