Project description:Fire disturbances are becoming more common, more intense, and further-reaching across the globe, with consequences for ecosystem functioning. Importantly, fire can have strong effects on the soil microbiome, including community and functional changes after fire, but surprisingly little is known regarding the role of soil fire legacy in shaping responses to recent fire. To address this gap, we conducted a manipulative field experiment administering fire across 32 soils with varying fire legacies, including combinations of 1-7 historic fires and 1-33 years since most recent fire. We analyzed soil metatranscriptomes, determining for the first time how fire and fire legacy interactively affect metabolically-active soil taxa, the microbial regulation of important carbon (C), nitrogen (N) and phosphorus (P) cycling, expression of carbohydrate-cycling enzyme pathways, and functional gene co-expression networks. Experimental fire strongly downregulated fungal activity while upregulating many bacterial and archaeal phyla. Further, fire decreased soil capacity for microbial C and N cycling and P transport, and drastically rewired functional gene co-expression. Perhaps most importantly, we highlight a novel role of soil fire legacy in regulation of microbial C, N, and P responses to recent fire. We observed a greater number of functional genes responsive to the interactive effects of fire and fire legacy than those affected solely by recent fire, indicating that many functional genes respond to fire only under certain fire legacy contexts. Therefore, without incorporating fire legacy of soils, studies will miss important ways that fire shapes microbial roles in ecosystem functioning. Finally, we showed that fire caused significant downregulation of carbon metabolism and nutrient cycling genes in microbiomes under abnormal soil fire histories, producing a novel warning for the future: human manipulation of fire legacies, either indirectly through global change-induced fire intensification or directly through fire suppression, can negatively impact soil microbiome functional responses to new fires.

Project description:Asthma is multi-factorial disorder, and microbial dysbiosis enhances lung inflammation and asthma-related symptoms. Probiotics has shown anti-inflammatory effect and could regulate the gut-lung axis. Thus, a three-month randomized, double-blind, and placebo-controlled human trial was performed to investigate the adjunctive efficacy of probiotics in managing asthma.

Project description:To understand why asthma remit with aging, we exposed mice across a range of ages to viral and allergic triggers of asthma exacerbations and inflammatory airway pathology. We found that pathology induced by Sendai virus (SeV) or influenza A virus (IAV) occurred selectively in juvenile mice in a microbiome-independent manner, while the same phenotypes induced by allergens were relatively insensitive to age. Age-specific responses to SeV included a juvenile bias towards type-2 airway inflammation that emerged early in infection and was lost with maturation. With aging, we observed progressive transcriptional changes to alveolar macrophages (AMs) including the acquisition of high-level MHC-II expression. Importantly, depleting AMs before SeV infection canceled the protective effects of maturity on post-viral airway pathology. Thus, age-related changes to the lung immune micro-environment alter host responses to viruses and may drive childhood asthma remission.

Project description:Humans vary markedly in their propensity to develop asthma, despite often being exposed to similar environmental stimuli. Similarly, mouse strains vary in susceptibility to airways pathology in experimental asthma. Sensitization and aerosol challenge with ovalbumin (OVA) induces eosinophil accumulation, mucus production and airways obstruction in BALB/c and C57BL/6 mice. In contrast, CBA/Ca mice show relatively little pathology. Allergen-induced production of IL-4, IL-5, IL-10 and IFN-g was detected in all three strains, with BALB/c mice generating the highest levels of IL-4, IL-5 and IL-10. Microarray analysis was used to identify genes differentially regulated in lung tissue after OVA challenge. Differentially regulated genes in the lungs of the asthma-susceptible C57BL/6 and BALB/c strains numbered 242 and 145, respectively, whereas only 42 genes were differentially expressed in the resistant CBA/Ca strain. In C57BL/6 mice, transcripts were enriched for adhesion molecules and this was associated with high levels of eosinophil recruitment. Differentially regulated genes in the lungs of only the asthma-susceptible strains numbered 64 and several of these have not previously been associated with asthma. Many of the genes differentially regulated in the susceptible strains were enzymes involved in inflammation. Using network analysis, mRNA for the anti-apoptotic protein survivin was found to be up-regulated in the lungs following allergen challenge. Survivin mRNA and protein were also expressed at high levels in eosinophils recovered by bronchoalveolar lavage from BALB/c and C57BL/6 mice. We propose that rapid apoptosis of lung eosinophils due to low expression of survivin contributes to the limitation of pathology in CBA/Ca mice Humans vary markedly in their propensity to develop asthma, despite often being exposed to similar environmental stimuli.

Project description:Alteration in the gene expression level in the lungs are thought to play a crucial role during the development of asthma and airway hyperresponsiveness. House dust mite induced allergic asthma is a Th2-lymphocyte driven inflammation characterized by airway hyperresponsiveness and eosinophilia while c-di-GMP, which is a potent mucosal adjuvant, induces a Th1-Th17 response accompanied by neutrophilia along with a low Th2 response. We aimed to identify changes in the expression of genes important in asthma pathology via targeted gene expression arrays.

Project description:Background: Microbial interventions against allergic asthma have robust epidemiologic underpinnings and the potential to recalibrate disease-inducing immune responses. Oral administration of OM-85, a standardized lysate of human airways bacteria, is widely used empirically to prevent respiratory infections, and a clinical trial is testing its ability to prevent asthma in at-risk children. On the other hand, we previously showed that intra-nasal administration of products from microbe-rich farm environments abrogate experimental allergic asthma. Objectives: To investigate whether direct administration of OM-85 to the airway compartment protects against experimental allergic asthma, and to identify protective cellular and molecular mechanisms activated through this natural route. Methods: BALB/cJ mice (7-8 weeks old) sensitized and challenged with Ovalbumin received OM-85 intra-nasally, and cardinal cellular and molecular asthma phenotypes were measured. Murine lung gene expression was profiled by RNA-sequencing. Results: Airway administration of OM-85 suppressed allergic asthma and altered the transcriptome profile in unfractionated lung tissue. Conclusion We provide the first demonstration that administration of a standardized bacterial lysate to the airway compartment protects from experimental allergic asthma by engaging multiple immune pathways.
