The Impact

AbstractDNA methylation is pivotal in orchestrating gene expression patterns in various mammalian biological processes. Perturbation of the bovine alveolar macrophage (bAM) transcriptome, due to Mycobacterium bovis (M. bovis) infection, has been well documented; however, the impact of this intracellular pathogen on the bAM epigenome has not been determined. Here, whole genome bisulfite sequencing (WGBS) was used to assess the effect of M. bovis infection on the bAM DNA methylome. The methylomes of bAM infected with M. bovis were compared to those of non-infected bAM 24 hours post-infection (hpi). No differences in DNA methylation (CpG or non-CpG) were observed. Analysis of DNA methylation at proximal promoter regions uncovered >250 genes harbouring intermediately methylated (IM) promoters (average methylation of 33–66%). Gene ontology analysis, focusing on genes with low, intermediate or highly methylated promoters, revealed that genes with IM promoters were enriched for immune-related GO categories; this enrichment was not observed for genes in the high or low methylation groups. Targeted analysis of genes in the IM category confirmed the WGBS observation. This study is the first in cattle examining genome-wide DNA methylation at single nucleotide resolution in an important bovine cellular host-pathogen interaction model, providing evidence for IM promoter methylation in bAM.

AbstractWe examined the activation and effector functions of lung macrophages in mediating immunity against helminth parasites. Using fate mapping mice, we showed that monocytes recruited to the lung assume an alveolar macrophage phenotype and comprise as many as 10% of alveolar macrophages by 7 days after inoculation. Monocyte-derived alveolar macrophages assume distinct transcriptional and metabolic profiles that include high levels of arginase expression and preferentially mediate helminth damage, both of which are dependent on neutrophil help. In further studies, arginase was shown to mediate helminth killing through localized depletion of arginine.
