Comparative transcriptomes reveal pro-survival and cytotoxic programs of mucosal-associated invariant T cells upon Bacillus Calmette–Guérin stimulation

ABSTRACT: To comprehensively characterize MAIT activation programs responding to different bacteria, we stimulated MAIT cells with E. coli to compare with Bacillus Calmette-Guérin (BCG), which remains the only licensed vaccine and a feasible tool for investigating anti-mycobacterial immunity in humans. Upon sequencing mRNA from the activated and inactivated CD8+ MAIT cells, results demonstrated the altered MAIT cell gene profiles by each bacterium with upregulated expression of activation markers, transcription factors, cytokines, and cytolytic mediators crucial in anti-mycobacterial responses.

Quantitative proteomic analysis of tumor tissues before and during Bacillus Calmette-Guérin instillation in bladder cancer

Project description:The alteration of protein expression profile mediated by Bacillus Calmette-Guérin (BCG) treatment remains unclear and is rarely studied. Three paired before BCG(pre-BCG) and during BCG(on-BCG) tissues were collected for proteomicsanalyses to describe the proteomic changes caused by BCG.

Human Bacille Calmette-Guérin vaccination elicits trained immunity via the hematopoietic progenitor compartment [PBMC]

Project description:Induction of trained immunity by human Bacille-Calmette-Guérin (BCG) vaccination is implicated in the beneficial heterologous effects of the vaccine, but the underlying mechanisms remain elusive. We performed global transcriptome analysis of sorted progenitors from bone marrow before (D0) and 90 days after vaccination (D90). BCG vaccination induced transcriptomic myeloid priming of the hematopoietic stem and progenitor cell (HSPC) compartment marked by the upregulation of myeloid and granulocytic pathways alongside the induction of transcription factors connected to myeloid cell function, namely Hepatocyte Nuclear Factors (HNF). These findings are corroborated by higher granulocyte numbers in BCG-vaccinated infants, HNF1-related SNP variants correlating with immune training and elevated serum levels of the HNF1 target gene SERPINA1. Taken together, we reveal a transcriptomic reprograming of HSPCs and peripheral monocytes as a trait of in vivo BCG-induced trained immunity.

Identification of a Novel Inflamed Tumor Microenvironment Signature as a Predictive Biomarker of Bacillus Calmette-Guérin Immunotherapy in Non–Muscle-Invasive Bladder Cancer

Project description:Improved risk stratification and predictive biomarkers of treatment response are needed for non–muscle-invasive bladder cancer (NMIBC). Here we assessed the clinical utility of targeted RNA and DNA molecular profiling in NMIBC. We performed RNA-based profiling by NanoString nCounter on non–muscle-invasive bladder cancer (NMIBC) clinical specimens and found that a novel expression signature of an inflamed tumor microenvironment (TME), but not molecular subtyping, was associated with improved recurrence-free survival after bacillus Calmette-Guérin (BCG) immunotherapy. We further demonstrated that immune checkpoint gene expression was not associated with higher recurrence rates after BCG.

Mycobacterium bovis Bacillus Calmette-Guerin (BCG) reprograms melanoma microenvironment to promote antitumor T cell responses

Project description:Intralesional therapy using Mycobacterium bovis Bacillus Calmette-Guérin (BCG) for cutaneous metastatic melanoma induces regression of injected, but also non-injected lesions. Tumor-associated macrophages (also known as M2) infiltrate solid tumors and impair antitumor immunity. Since macrophages play a pivotal role in both tumors and mycobacterial infections, we hypothesized BCG alters M2 to promote antitumor immunity. BCG-treated, in vitro-polarized M2 (M2-BCG) show dramatic transcriptional changes involving inflammation, immune cell recruitment, cross-talk and activation pathways. Mechanistic network analysis indicates potential for M2-BCG to improve IFN-γ responses, frequently used as a marker for successful antitumor immunity. Accordingly, we found an increased frequency of IFN-γ-producing CD4+ T cells responding to M2-BCG vs mock-treated M2 (p<0.05). Moreover, supernatant from M2-BCG increased the frequency of granzyme B-producing CD8+ tumor-infiltrating lymphocytes (TIL) responding to autologous melanoma cell lines (p<0.01). Comparing the transcriptome of injected vs uninjected lesions biopsied from IL-BCG patients showed immune function prevailing in injected lesions, with the most enriched pathways representing T cell activation mechanisms. In vitro BCG-infected tumor cells also stimulated IFN-γ production from HLA-A2-restricted syngeneic TIL from the same melanoma patient (p<0.05). Together, our data indicates BCG can promote an antitumor microenvironment in cutaneous metastatic melanoma.

Project description:This experiment explored the transcriptional response of human peripheral blood mononuclear cells (PBMC) isolated from BCG-vaccinated individuals following 6 days of in vitro stimulation with 2x10^5 cfu of different Bacillus Calmette-Guérin (BCG) strains or 100 ng/ml Mycobacterium tuberculosis-derived purified protein derivative (PPD). The BCG strains used were BCG Russia (Russian BCG-I sub-strain), BCG Japan (Tokyo 172 sub-strain), BCG Denmark (Danish 1331 sub-strain) & BCG Pasteur.

Cultivation impact on the protein expression profile of Mycobacterium bovis BCG strains Moreau and Pasteur

Project description:The BCG vaccine (Bacille Calmette-Guerin), only prophylactic measure against tuberculosis (TB), was obtained in the early twentieth century by Calmette and Guérin after 231 passages of a M. bovis clinical isolate in medium containing glycerin and bovine bile. Its protective efficacy against pulmonary TB in adults varies from 0-80% and the genetic differences among vaccines strains used worldwide contribute to this variation. The Brazilian vaccine strain, BCG Moreau, is considered a primitive strain and more immunogenic, closer to the original BCG when compared to newer strains, such as BCG Pasteur (reference strain). The characterization of BCG sub-strains can contribute not only to a better understanding of the vaccine and its protective effect, but also, in elucidating how different BCG culture conditions may contribute to the impact on the host's immune response. Thus, we aimed to characterize the differences in gene expression through the intracellular proteomic profile of BCG Moreau and Pasteur strains, cultivated in Sauton or 7H9 medium, using the methodology of two-dimensional electrophoresis (2DE) and mass spectrometry.
