AbstractThe tumor microenvironment exists in a state of dynamic equilibrium, in which a balance of agonist and antagonist signals govern the anti-tumor immune responses. Previous studies have shown that chemotherapy could shift this balance in favor of agonistic signals for the anti-tumor immune responses mounted by CD8+ cytotoxic T lymphocytes (CTL), providing sufficiently high antigen density within the tumor. We undertook the current study to characterize the anti-tumor immune response following chemotherapy and its underlying mechanisms. We show that this ‘adjuvant effect’ of chemotherapy is, at least parti...

AbstractResistance to chemotherapy is widely recognized as one of the major factors limiting therapeutic efficacy and influences clinical outcomes in patients with cancer. Many studies on various tumor types have focused on combining standard-of-care chemotherapy with immunotherapy. However, for cervical cancer, the role of neoadjuvant chemotherapy (NACT) on the local immune microenvironment is largely unexplored. We performed a pilot study on 13 primary cervical tumor samples, before and after NACT, to phenotype and enumerate tumor-infiltrating T-cell subpopulations using multiplex immunohistochemistry (CD3, CD8, FoxP3, K...

When William Stewart Halsted described the radical mastectomy in 1894, it was thought that a cure for breast cancer lay in maximally invasive and often morbid surgery. Our understanding of breast cancer has changed immeasurably in the subsequent century in which innumerable preclinical and clinical studies have demonstrated that advanced breast cancer is a systemic disease that requires a multimodality approach that includes both local (surgery and radiation) and systemic therapies (chemotherapy, endocrine therapy, and/or immunotherapy).

In conclusion, a polypharmacology approach of combining established, prolongevity drug inhibitors of specific nodes may be the most effective way to target the nutrient-sensing network to improve late-life health. Deletion of p38α in Neurons Slows Neural Stem Cell Decline and Loss of Cognitive Function in Mice Researchers here provide evidence for p38α to be involved in the regulation of diminished neural stem cell activity with age. It is thought...

Immunotherapies such as the cytotoxic T-lymphocyte–associated protein 4 inhibitor ipilimumab and the programmed cell death protein 1 inhibitor nivolumab have become ubiquitous in cancer treatment. Recently, the FDA approved nivolumab with or without ipilimumab for the treatment of refractory small cell lung cancer. Immunotherapies increase the immune response to cancer cells by interfering with inhibitory molecular pathways that prevent tumor cell killing, thus augmenting tumor cell death without many of the cytotoxic side effects associated with chemotherapy. However, this augmented immune response may result in unw...

Results from a phase III clinical trial comparing Keytruda (pembrolizumab) to standard chemotherapy shows the immunotherapy drug still has a long way to go as a viable treatment option for malignant pleural mesothelioma. Keytruda did not improve progression-free survival for mesothelioma patients who progressed after first-line chemotherapy. The disappointing results from the PROMISE-meso study were presented at the European Society of Medical Oncology (ESMO) annual meeting last week. It was the first randomized trial comparing progression-free survival between immunotherapy and first-line chemotherapy for mesothelioma p...

Authors: Mohanty R, Chowdhury CR, Arega S, Sen P, Ganguly P, Ganguly N Abstract Cancer has recently been identified as the leading cause of mortality worldwide. Several conventional treatments and cytotoxic immunotherapies have been developed and made available to the market. Considering the complex behavior of tumors and the involvement of numerous genetic and cellular factors involved in tumorigenesis and metastasis, there is a need to develop a promising immunotherapy that targets tumors at both the cellular and genetic levels. Chimeric antigen receptor (CAR) T cell therapy has emerged as a novel therapeuti...

Abstract Immunological principles based on Treg cell self-stabilization and the discovery that tumors are capable of evading the body's defense mechanism have led to more effective immuno-oncology therapies. Hence, next generation immunotherapy can only be effective if researchers have an in-depth understanding of the function and regulation of Treg cells in antitumor immunity combined with the discovery of new immunity targets. This can enhance clinical efficacy of future and novel therapies and reduces any adverse reactions arising from the latter. This review of the literature discusses tumor treatment strategi...
