Common chemotherapeutic agent reduces resistance to virus therapy in brain tumor patients

Preclinical studies of oncolytic virus therapy in malignant glioma are promising; however, a potential problem with this approach is that the body’s own immune system can recognize the virus and clear the infection, resulting in reduced therapeutic effects. For this study, researchers used a mouse model with an intact immune system to mimic what would occur in humans to determine how the immune system clears the oncolytic virus. They found that the area surrounding malignant gliomas has a high number of immune cells called microglial cells and macrophages…

Synthetic lethality offers new approach to kill tumor cells, explains researcher — ScienceDaily

“Genetic alterations in cancer in humans may involve gene inactivation, amplification or inactivation,” said List.These changes are not present in nonmalignant cells. Common chemotherapeutic agents aggressively kill tumor cells irrespective of genetic alterations.They also have a negative impact on normal cells and can cause significant side effects. …

New screening approach quickly identifies small proteins unique to melanoma cells

The new approach is outlined in an article published online by Nature Medicine in May. A previous phase 2 clinical trial showed substantial regression of metastatic lesions in up to 70 percent of melanoma patients who were treated with self-donated tumor-infiltrating lymphocytes. "The trial, which involved the adaptive transfer of a patient’s own immune cells, showed a complete tumor regression lasting at least five years in nearly 40 percent of the patients," Teer said. …
