The Study Highlights the Identification of a Whole Blood Phenotypic and Transcriptional Signature Predictive of the HBV Vaccine Hypo-response
Montreal, Canada – January 26, 2016— Caprion Biosciences announced today the publication of results from studies conducted using its ImmuneCarta® flow cytometry technologies which identified potential baseline predictors and mechanisms of response to the HBV vaccine. The article, titled: “Pre-vaccination inflammation and B-cell signaling predict age-related hypo-response to hepatitis B vaccination” was published in the January 8, 2016 issue of NATURE and includes among the co-authors several Caprion scientists as well as scientific collaborators from Merck Research Laboratories, the Vaccine and Gene Therapy Institute of Florida, the University Hospitals of Cleveland and Case Western Reserve University.
The results of the study suggest that heightened expression of genes that augment B-cell responses and higher memory B-cell frequencies before vaccination were correlated with stronger responses to the Hepatitis B vaccine. In contrast, higher levels of inflammatory response transcripts pre-vaccination and increased frequencies of pro-inflammatory innate cells were correlated with weaker responses to the vaccine. These findings seem to fit well with the “inflammaging” hypothesis stating that low-grade, chronic inflammation is a significant risk factor associated with morbidity and mortality in the elderly.
As the number elderly individuals increase worldwide, prevention of severe infections in this population is ever more pressing. Although vaccination offers a proven approach for such prevention, age-related vaccine hypo-responses may reduce their potential benefit. The results pave the way for further studies designed to understand the cellular and molecular mechanisms of the immune hypo-response, which may contribute to the development of novel immunotherapies aimed at overcoming the immunesenescent state associated with aging.
Martin LeBlanc, CEO of Caprion, stated, “We are very pleased to have participated in the study and collaboration that yielded this high profile publication. These results provide another tangible illustration of Caprion’s ability to collaborate with leading academic and pharma industry partners to deliver valuable immunological insights and of the potential of our ImmuneCarta platform to deliver valuable predictive biomarkers of response to immuno-therapies.”
