Targeting Multiple Receptors to Increase Checkpoint Blockade Efficacy

Targeting iNOS to increase efficacy of immunotherapies

Inducible NO synthase (iNOS/NOS2) protein expression is a well-studied predictor of poor outcome in multiple cancers, and it has also been associated with inflammatory and immunosuppressive processes in the tumor microenvironment. Immunotherapies are becoming increasingly key components in cancer treatment, and iNOS is receiving more attention as a potential regulator of treatment resistance. A...

Timeline: Checkpoint Blockade

Immunomodulation: checkpoint blockade etc.

The immune microenvironment is considered a major obstacle to generating an effective antitumor immune response. Checkpoint inhibitors manipulate the co-stimulatory response between antigen-presenting cells and immune cells-or between the tumor and immune cells-to elicit an antitumor immune response that would have otherwise been suppressed. Checkpoint inhibitors have shown great promise in the...

Cyclooxygenase-2 blockade can improve efficacy of VEGF-targeting drugs

Anti-angiogenic therapies were approved for different cancers. However, significant primary and secondary resistance hampers efficacy in several tumor types including breast cancer. Thus, we need to develop clinically applicable strategies to enhance efficacy of anti-angiogenic drugs.We report that anti-angiogenic therapies can induce upregulation of cyclooxygenase-2 (Cox-2) and of its product ...

Corticosteroids and immune checkpoint blockade

checkpoint blockade to stimulate the immune response have demonstrated promising outcomes in advanced malignancies [1]. As a result, novel cancer immunotherapy was named a scientific breakthrough of the year in 2013 by Science. Consistent with its mechanism of action of de novo stimulation or enhancement of pre-existing T cell responses, a number of immune-related adverse events (irAEs) have be...
