Anti-pancreatic tumor efficacy of a Listeria-based, Annexin A2-targeting immunotherapy in combination with anti-PD-1 antibodies

ConclusionsFor the first time, a listeria vaccine-based immunotherapy was shown to be able to induce a tumor antigen-specific T cell response within the tumor microenvironment of a “cold” tumor such as PDAC and sensitize the tumor to checkpoint inhibitor therapy. Moreover, this combination immunotherapy led to objective tumor responses and survival benefit in the mice with spontaneously developed PDAC tumors. Therefore, our study supports developing Lm-ANXA2 as a therapeut ic agent in combination with anti-PD-1 antibody for PDAC treatment.

This article presents a unique 3D biocompatible Aluminum-based quantum structure (QS) for in vitro cancer detection using Surface Enhanced Raman Scattering (SERS). The Al-based QSs fabricated using ultrashort pulsed laser are of two distinct surface characters, wrinkled and smooth spherical. The limit of detection for chemical sensing of Crystal Violet and Rhodamine 6G by the Al-QS was driven up to single molecule sensing (femtomolar concentration). Biological sensing of cysteine, a disease biomarker and carcinoembryonic antigen (CEA), a cancer biomarker was also tested by the Al-QS. The ability of in vitro cell detection ...

In this study, four different weight% of Punica granatum fruit peel extract were used as green stabilizers to synthesize IONPs followed by a series of characterization experiments and in vitro anticancer evaluation. Results revealed that all synthesized IONPs have high degree of crystallinity and purity. The optimum saturation magnetization, and hydrodynamic size were found to be ∼69 emu.g−1, and 26.52 nm, respectively. Morphological studies demonstrated that adding peel extract decreased size of NPs with the average particle size below 11 nm. Cytotoxicity assay showed that the IONPs were not react...

Herein, the synthesis, structural analysis and anticancer activity of the novel triterpenoid thiazole 3 is reported. The synthesis was carried out through the bromination of ochraceolide A (1) and the subsequent heterocyclic condensat...

In this study, two groups (4% PHB supplementation diets and control with basal diets) with 30-day feeding were set to study the effect of PHB supplementation on immune-related gene expression by qRT-PCR, time-course CyHV-2 replication in vivo by qPCR and intestinal microbiota by illumine high-throughput sequencing. PHB supplementation significantly up-regulated transcriptional levels of eight immune-related genes, decreased cumulative mortality of gibel carp and early CyHV-2 replication in spleen in vivo (P

GudasAbstractEthanol (EtOH) is a recreationally ingested compound that is both teratogenic and carcinogenic in humans. Because of its abundant consumption worldwide and the vital role of stem cells in the formation of birth defects and cancers, delineating the effects of EtOH on stem cell function is currently an active and urgent pursuit of scientific investigation to explicate some of the mechanisms contributing to EtOH toxicity. Stem cells represent a primordial, undifferentiated phase of devel...

This study demonstrates that the concentrations of PM-bound PAHs are mutagenic and that the Excess Cancer Risks exceed the USEPA standard limits. PMs cause cytotoxicity and can also induce genotoxicity to human health analyzed by cell culture and gel electrophoresis. This study helps to promote research to evaluate the PMs bound PHEs toxicity in diverse human cell lines and also their relationship with climatic factors as well as quantitative source apportionment for mitigation purposes.Graphical abstract

Abstract No immunotherapy strategy is yet offering consistent results against Pancreatic ductal adenocarcinoma (PDAC). A randomized clinical trial testing repeated immunization with a Listeria monocytogenes-based vaccine encoding for mesothelin in combination with a GM-CSF-transfected allogeneic pancreatic cell vaccine reports no survival benefit for the vaccinated patients.
