(Submitter supplied) Environmental microbial triggers shape the development and functionality of the immune system. Alveolar macrophages (AMs), tissue-resident macrophages of the lungs, are in constant and direct contact with inhaled particles and microbes. Such exposures likely impact AM reactivity to subsequent challenges by immunological imprinting mechanisms referred to as trained immunity. Here, we investigated whether a ubiquitous microbial compound has the potential to induce AM training in vivo. more...

(Submitter supplied) Respiratory viral infections reprogram pulmonary macrophages with altered anti-infectious functions. However, the potential function of virus-trained macrophages in antitumor immunity in the lung, a preferential target of both primary and metastatic malignancies, is not well understood. Using mouse models of influenza and lung metastatic tumors, we show here that influenza trains respiratory mucosal-resident alveolar macrophages (AMs) to exert long-lasting and tissue-specific antitumor immunity. more...

(Submitter supplied) Recent studies suggest that training of innate immune cells such as tissue-resident macrophages by repeated noxious stimuli can heighten host defense responses. However, it remains unclear whether trained immunity of tissue-resident macrophages also comprises enhanced injury resolution capacity to counterbalance the heightened inflammatory responses. Here, we studied lung-resident alveolar macrophages (AMs) pre-challenged with either the bacterial endotoxin or with Pseudomonas aeruginosa and observed that these trained AMs showed greater resilience to pathogen-induced cell death. more...

(Submitter supplied) Rationale: Lipopolysaccharide (LPS) is ubiquitous in the environment. Inhalation of LPS has been implicated in the pathogenesis and/or severity of several lung diseases, including pneumonia, chronic obstructive pulmonary disease and asthma. Alveolar macrophages are the main resident leukocytes exposed to inhaled antigens. Objectives: To obtain insight into which innate immune pathways become activated within human alveolar macrophages upon exposure to LPS in vivo.

(Submitter supplied) RNA-sequencing demonstrated Acod1 (Aconitate decarboxylase 1) as one of the top genes induced by air polution particulate matter (PM) in macrophages. We therefore sought to determine the effect of both exogenous itaconate (4-octyl itaconate) and endogenous itaconate on PM-induced inflammation in macrophages through RNA sequencing.

(Submitter supplied) Innate immune memory is a new important area of research. However, innate immune memory at the major mucosal sites remains poorly understood. Here we show that respiratory viral infection induces long-lasting memory alveolar macrophages (AM). Memory AM are programed to express high MHC II, carry a defense-ready gene signature, and produce, upon re-stimulation, neutrophil chemokines. Using a multitude of approaches, we reveal that the priming, but not maintenance, of memory AM requires the help from effector CD8 T cells. more...

(Submitter supplied) To study the regulation of Lepr on transcriptome in WT and Lepr KO AMs under resting state and after LPS stimulation, Lepr-sufficient (Lepr+/+, Lyz2-Cre) and Lepr-deficient (Leprfl/fl, Lyz2-Cre) alveolar macrophages (AMs) were isolated by collecting BALF. Lipopolysaccharide (LPS) was added in vitro for 1h or cells were left untreated. Total RNA was extracted for deep sequencing. Gene expression in WT and Lepr KO cells were analyzed.

(Submitter supplied) Purpose: Determine if alveolar macrophage express different transcriptional programs when CD44 expression is lost. Methods: Alveolar macrophages were isolated from the bronchoalveolar lavage of 6-10 week old CD44+/+ and CD44-/- female mice. RNA was isolated an sequenced using Illumina NextSeq 500. RNA was sequenced by the UBC Biomedical Research Center. RNA quality, 18S and 28S ribosomal RNA with RIN = 9.6, was determined by Agilent 2100 Bioanalyzer following standard protocol for NEBnext Ultra ii Stranded mRNA (New England Biolabs). more...
