Autologous tumour cell vaccines vs. dendritic cell vaccines: What’s best, and why?

Understanding the best approach for tumour vaccinations is of growing importance in the personalized cancer immunotherapy field. Current models use a variety of treatments, but two include the use of irradiated autologous tumour cells (TCV), or autologous dendritic cells loaded with tumour associated antigens (DCV). In a randomized trial of metastatic melanoma patients undergoing either TCV or DCV, DCV patient survival was far superior at 43.4 vs 20.5 months. Why was the response more effective when the same antigens were provided to the immune response? Dillman, Robert O., et al. brought some answers in a paper published in the Journal for immunotherapy of cancer in 2018). Looking at the cytokine “milieu” with the Quantibody 200 Biomarker Microarray Service helped the authors in understanding the differences in vaccine responses.

For many pathologies such as cancer or neurological disorders, it has been found that Histone Deacetylase (HDAC) activity is disrupted, making them promising targets for drug development. Scientists need access to a broade range of products ( Active Enzyme, inhibitors/activators, Biochemical screening assays…), to simplify their research and identification of HDAC inhibitors.

Rockland Immunochemicals, Inc., (Rockland) provide the highest quality antibodies to the academic, biopharma, and diagnostic industries for use in basic research, assay development, preclinical and clinical studies, and bioprocessing. With facilities in Pennsylvania established since 55 years ago, Rockland manufactures products ideally suited for integration into critical assays such as western blotting, immunohistochemistry (IHC), immunofluorescence microscopy (IF), ELISA, flow cytometry, and 2D imaging. Their antibodies show remarkable quality and reproducibility from batch to batch. Their popular anti-RFP is one example out of many.

Demonstrating Rockland’s commitment in this matter (manufacturing antibodies of high quality and reproducibility), Rockland’s CSO, Dr. Carl Ascoli, testified at the US National Academies of Sciences, Engineering and Medicine’s third of six public sessions on Reproducibility and Replicability in Science on April 18th this year.

I am following up on my series of posts based on the work done by Chris Bohl and collaborators at Sekisui Xenotech. Here, he looks at the effect of cryopreservation on pooled hepatocytes metabolic activities, and how the patented Cryostax technology can address this issue.
