Transcriptional signatures to AS01-adjuvanted tuberculosis vaccine in naïve and primed participants

Project description:In this exploratory post-hoc analysis of clinical trial samples (clinicalTrials.gov: NCT01424501), we compared gene expression patterns elicited by two immunizations with the candidate tuberculosis (TB) vaccine M72/AS01, between three groups of individuals with different levels of memory responses to TB antigens before vaccination

Adjuvant associated peripheral-blood mRNA profiles and kinetics induced by the adjuvanted recombinant-protein candidate tuberculosis vaccine M72/AS01 in BCG-vaccinated adults

Project description:Systems biology has the potential to identify gene signatures associated with vaccine immunogenicity or protective efficacy. The main objective of our study was to identify optimal post-vaccination time points for evaluating blood RNA-expression profiles in recipients of the candidate tuberculosis vaccine M72/AS01. In this phase II open-label study (NCT01669096), healthy Bacillus Calmette-Guérin (BCG)-primed, HIV-negative adults were administered two doses (30-days apart) of M72/AS01. Blood samples were collected pre-dose 1, pre-dose 2 and 1, 7, 10, 14, 17 and 30 days post-dose 2. RNA expression in blood and peripheral-blood mononuclear cells (PBMCs) was quantified using microarray technology. The data analysis used as a reference, a PBMC-gene signature that was associated with the protective efficacy of a similarly adjuvanted candidate malaria vaccine. Peripheral-blood CD4+ T-cell reactivity, serum interferon-gamma (IFNG) concentrations and safety were also assessed. Twenty subjects completed the study and 18 subjects received two doses. The observed safety profile was similar to previous trials. Serum IFNG responses and M72-specific CD4+ T cell responses to vaccination were detected as expected, based on previous trial experience. PBMC and whole-blood RNA-expression data at day 14 post-dose 2 relative to pre-vaccination and whole-blood RNA-expression data at 7, 10, and 17 days post-dose 2 relative to pre-vaccination could be used to classify vaccine recipients into gene-signature positive or gene-signature negative groups. In conclusion, whole blood sampled from the 7, 10, 14, or 17 day post-vaccination time points, in addition to pre-vaccination, could be selected to assess potentially clinically relevant responses to M72/AS01 using transcriptome analysis.

Expression data from draining lymph node of mice immunized with AS01 or its components

Project description:Immunization with adjuvanted antigen results in coordinate changes in gene expression. Combination adjuvants exploit the interplay between different immunostimulants to promote immune response to vaccination. The Adjuvant System 01 (AS01) is a liposome-based combination adjuvant which contains two immunostimulants, MPL and QS-21 Here, we assess the contribution of the components of AS01 on its immunogenicity by comparing the transcriptional response induced in the draining lymph node by AS01, MPL and QS-21 at 2,4 or 6h after intramuscolar (i.m.) immunization

A baseline transcriptional signature associates with clinical malaria risk in RTS,S/AS01-vaccinated African children

Project description:In a phase 3 trial in African infants/children, the RTS,S/AS01 (GSK) vaccine showed moderate efficacy against clinical malaria. We aimed to identify RTS,S/AS01-induced signatures associated with clinical malaria by analyzing antigen-stimulated peripheral blood mononuclear cells sampled from a subset of trial participants at baseline and month 3 (one month post-final dose). RTS,S/AS01 vaccination was associated with downregulation of B-cell and monocyte-related blood transcriptional modules (BTMs) and upregulation of T-cell related BTMs, as well as higher month 3 (vs baseline) (CSP)-specific CD4+ T-cell responses. For some RTS,S/AS01-associated BTMs, month 3 levels correlated with anti-circumsporozoite protein (CSP) IgM and inversely with anti-CSP IgG responses. There were few RTS,S/AS01-associated BTMs whose month 3 levels correlated with malaria risk. In contrast, baseline levels of dendritic cell and monocyte RTS,S/AS01-associated BTMs correlated with malaria risk. A cross-study analysis supported generalizability of these correlations to healthy, malaria-naïve adults, suggesting inflammatory monocytes may inhibit protective RTS,S/AS01-induced responses.

Transcriptional profiling of immunity to the MF-59 – adjuvanted influenza vaccine in children

Project description:In this study, we performed a systems-level analysis of immune responses to the trivalent inactivated influenza vaccine adjuvanted with MF-59 in children (15-24 months old) and in young healthy adults. We analyzed transcriptional responses elicited by vaccination in peripheral blood, as well as cellular and antibody responses following primary and booster vaccinations. The pediatric population is a major target of vaccination, yet there is a paucity of studies on the transcriptional response of immunity to vaccination in this special population. In this study, we performed a systems-level analysis of immune responses to the trivalent inactivated influenza vaccine adjuvanted with MF-59 in children (15-24 months old) and in young healthy adults. We analyzed transcriptional responses elicited by vaccination in peripheral blood, as well as cellular and antibody responses following primary and booster vaccinations. Our analysis revealed that primary vaccination induced a persistent transcriptional signature of innate immunity; booster vaccination induced a transcriptional signature of an enhanced memory-like innate response, which was consistent with enhanced activation of myeloid cells assessed by FACS. Furthermore, we identified a transcriptional signature of type 1 IFN response post booster vaccination and at baseline that was correlated with the local reactogenicity to vaccination, and defined an early signature of the hemagglutinin antibody titers. These results highlight an adaptive behavior of the innate immune system in evoking a memory-like response to secondary vaccination and define molecular correlates of reactogenicity and immunogenicity in infants.
