Oncolytic virotherapy is an effective immunotherapeutic approach for cancer treatment via a multistep process including direct tumor cell lysis, induction of cytotoxic or apoptosis-sensitizing cytokines and promotion antitumor T responses. Solid tumors limit the effectiveness immunotherapeutics in diverse ways such as secretion immunosuppressive expression immune inhibitory ligands to inhibit function. Blocking programmed death protein (PD)-1 signaling, which mediates suppression engagement...
Oncolytic viral (OV) therapy, which uses genetically engineered tumor-targeting viruses, is being increasingly used in cancer clinical trials due to the direct cytolytic effects of this treatment that appear provoke a robust immune response against tumor. As OVs enter tumor cells, intrinsic host defenses have potential hinder replication and spread within mass. In report, we show histone deacetylase 6 (HDAC6) cells appears alter trafficking post-entry from nucleus toward lysosomes. glioma...
Ewing sarcoma is a highly aggressive cancer that promotes the infiltration and activation of pro-tumor M2-like macrophages. Oncolytic virotherapy selectively infects destroys cells promising option for treating sarcoma. The effect tumor macrophages on oncolytic virus therapy, however, variable among solid tumors unknown in We tested effects macrophage reduction using liposomal clodronate (Clodrosome) trabectedin antitumor efficacy intratumoral herpes simplex virus, rRp450, two xenograft...
Multiple studies have indicated that in addition to direct oncolysis, virotherapy promotes an antitumor cytotoxic T cell response important for efficacy. To study this phenomenon further, we tested three syngeneic murine sarcoma models displayed varied degrees of permissiveness oncolytic herpes simplex virus replication and cytotoxicity vitro, with the most permissive being comparable some human tumor lines. The vivo effect ranged from no or modest complete regression protection rechallenge....
Oncolytic viruses are an emerging class of cancer therapeutics that couple cytotoxicity with the induction anti-tumor immune response. Host-virus interactions complex and modulated by a tumor microenvironment whose immunosuppressive activities can limit effectiveness immunotherapies. In effort to improve this aspect oncolytic virotherapy, we combined herpes virus HSV1716 transforming growth factor beta receptor 1 (TGF-βR1) inhibitor A8301 treat syngeneic models murine rhabdomyosarcoma.

GP101 is a single chain diabody composed of Fv regions antibodies directed to CD3 and CD19. It designed mimic commercial blinatumomab (Blincyto®) that simultaneously co-engages patient T lymphocytes CD19 positive B cell leukemias lymphomas, facilitating their targeted destruction. This study details the purification protein development highly sensitive ELISA for its detection, achieving sensitivity 15pg/mL in 25% mouse serum. has been validated according GLP standards.
Abstract Purpose: Novel therapeutic regimens are needed to improve dismal outcomes associated with late-stage ovarian cancer.

T cells redirected to cancer either via a chimeric antigen receptor (CAR-T) or bispecific molecule have been breakthrough technologies; however, CAR-T require individualized manufacturing and bispecifics generally continuous infusions.

High Mobility Group Box 1 (HMGB1) is a multifunctional protein that plays various roles in the processes of inflammation, cancer, and other diseases. Many reports document abundant HMGB1 release following infection with oncolytic viruses (OVs). Further, groups including previous from our laboratory highlight synergistic effects OVs chemotherapy drugs. Here, we show virus-free supernatants have varying cytotoxic potential, actively secreted by two established fibroblast cell lines (NIH 3T3...
Oncolytic engineered herpes simplex viruses (HSVs) possess many biologic and functional attributes that support their use in clinical trials children with solid tumors. Tumor cells, an effort to escape regulatory mechanisms would impair growth progression, have removed protected them from virus infection eventual virus-mediated destruction. Viruses exploit this weakness, like mutant HSV, can be safely employed as tumor cell killers, since normal cells retain these antiviral strategies. Many...
Background Oncolytic virotherapy (OV) is an immunotherapy that incorporates viral cancer cell lysis with engagement of the recruited immune response against cells. Pediatric solid tumors are challenging targets because they contain both inert environment and a quiet antigenic landscape, making them more resistant to conventional OV approaches. Further complicating this, herpes simplex virus suppresses host gene expression during infection. Methods We therefore developed multimodal oncolytic...
Herpes simplex virus (HSV) is one of the many viruses that have been modified or adapted for oncolytic purposes. There are two serotypes HSV, HSV-1 and HSV-2. The majority HSVs, including T-VEC which has recently approved by US Food Drug Administration (FDA) clinical use in treating late stage melanoma patients, derived from HSV-1. Recently, we others developed several HSV-2 based viruses. During our vitro characterization both (Baco-1 FusOn-H2 HSV-2), noticed there a subpopulation cancer...

Here we report disrupts intrinsic cellular anti-viral response which increases viral transcript spread throughout tumor cells. also extended our synergy findings syngeneic murine are poorly susceptible virus infection.

Patients with osteosarcoma (OS), a debilitating pediatric bone malignancy, have limited treatment options to combat aggressive disease. OS thrives on insulin growth factor (IGF)-mediated signaling that can facilitate cell proliferation. Previous efforts target IGF-1R were mostly unsuccessful, likely due compensatory through alternative splicing of the receptor (
