Stem Cell Vaccine Carries Potential as Mesothelioma Treatment
Researchers at the Stanford University School of Medicine believe a patient-specific stem cell vaccine could become part of mesothelioma treatment — and possibly prevention — in the future. The belief stems from their recent study that demonstrated a consistent immunologic response with genetically-altered stem cells in laboratory mice carrying particular cancer cells. “This could potentially play a role for a large group of — if not all — cancers,” Dr. Joseph Wu, director of the Stanford Cardiovascular Institute, told Asbestos.com. “We envision it potentially being used as a vaccine or adjuvant treatment for mesothelioma.” The study involved induced pluripotent stem cells (IPS), which are cells taken from the blood or skin and genetically reprogramed. This allows the cells to attack or prevent cancerous tumors when mixed with a generic immune-stimulating agent. Vaccine Shows Anti-Tumor Response The study tested mice infected separately with breast cancer, melanoma and mesothelioma cells. The anti-tumor response rate was similar in all three types of cancer. “This is significant for future cancer therapies, that we now have a surrogate cell that can provide the immune system with a large amount of cancer-related antigens,” Wu said. “Based on preliminary studies, the effectiveness of our vaccine is not limited to one cancer.” IPS cells typically are used in regenerative medicine, often to repair damage fro...
Conclusion: This paper addresses the clinical implications of performing numerous CT examinations in patients with cancer, providing clinicians with information regarding methods to reduce risk factors in this patient population.Blood Purif 2018;46:56 –69
Conclusions: RDLs are frequently observed in high-risk patients for gastric cancer after eradication. M-NBI demonstrated significantly superior diagnostic efficacy with respect to RDL.Digestion 2018;98:48 –55
Conclusion: In the hands of an expert, EUS-guided biliary drainage with the use of LAMS is an efficacious and safe option for patients with distal malignant biliary stricture, not amenable to ERCP.Digestion 2018;98:1 –10
This study showed that ESE-16 exposure leads to the aggregation of acidic vesicles, identified as lysosomes, not accompanied by an induction of autophagy. Therefore, ESE-16 disrupts normal endocytic vesicle maturation likely through the inhibition of the microtubule function.Pharmacology 2018;102:9 –16
Preclinical and clinical studies have shown that viral-based immunotherapy has the potential to overcome resistance to immune checkpoint blockade (ICB) and to fill the unmet needs of many cancer patients. Poxviruses, such as modified vaccinia virus Ankara (MVA), have the potential as cancer immunotherapeutic agents. We recently showed that intratumoral (IT) delivery of inactivated modified vaccinia virus Ankara (iMVA) induces antitumor systemic immunity via the STING-mediated cytosolic DNA-sensing pathway and Batf3 –dependent CD103+/CD8+ dendritic cells (DCs).
MicroRNA-155 (miR-155) has recently been shown to regulate anti-tumor immune responses. However, its specific functions within distinct immune cell types during this process have not been delineated utilizing conditional knockout mouse models. In recently published work, we discovered a role for miR-155 expression within the T cell compartment during the immune response to syngeneic B16f10 mouse melanoma tumors. We found that miR-155 expression within T cells is required to limit syngeneic tumor growth and promote interferon gamma (IFN γ) production within the tumor microenvironment.
In this study, we investigated the role of Bregs in tumor immunity. We used B cell-specific phosphatase and tensin homolog (PTEN)-deficient mice and B16F10 melanoma cells, which were subcutaneously injected into mice.
Autologous iPSC-Based Vaccines Elicit Anti-tumor Responses In Vivo. Cell Stem Cell. 2018 Feb 08;: Authors: Kooreman NG, Kim Y, de Almeida PE, Termglinchan V, Diecke S, Shao NY, Wei TT, Yi H, Dey D, Nelakanti R, Brouwer TP, Paik DT, Sagiv-Barfi I, Han A, Quax PHA, Hamming JF, Levy R, Davis MM, Wu JC Abstract Cancer cells and embryonic tissues share a number of cellular and molecular properties, suggesting that induced pluripotent stem cells (iPSCs) may be harnessed to elicit anti-tumor responses in cancer vaccines. RNA sequencing revealed that human and murine iPSCs express tumor-associated antige...
Conclusion: PTX3 could be a promising biomarker to differentiate PPE from other causes of pleural effusions. In PPE, an increased level of pleural fluid PTX3 level without a significant increase in serum PTX3 level may reflect a more intense local inflammation than those occur in MPE or TPE.
Conclusions • Physicians should have no hesitation prescribing natural progesterone. The evidence is clear that progesterone does not cause breast cancer. Indeed, progesterone is protective and preventative of breast cancer. PMID: 29055286 [PubMed - as supplied by publisher]
