Opening Conference: Unlocking the power of trained immunity in pulmonary infections
Pr. Maziar Divangahi, McGill University, Canada 

The constant exposure of humans to potentially life-threatening respiratory challenges pose a major public health problem, with an estimated 20% of all deaths annually worldwide resulting from lung diseases. The lungs, which are constantly exposed to the outside environment, can become a “portal” entry to infectious agents, toxic gases, and particulate matters as we breath approximately 11,000 liters of air every day. To overcome these environmental insults lung innate immune defense system must be tightly regulated; eliminating invading pathogen, minimizing collateral damage, and preserving lung physiology to perform its main task of gas-exchange. These wide range of innate regulatory circuits also promote lung adaptation throughout the lifespan. Understanding the long-term impacts of constant exposure to environmental challenges, vaccines, the on/off inflammation on the lung regulatory networks, and subsequently the generation of “lung memory” is crucial for developing novel therapeutic interventions.

Keynote: Homeostasis: Just a level of inflammation
Pr. Paul Kubes, University of Calgary, Canada 

Immunophysiology is a relatively novel concept that implies that the immune system is integrated into tissues and cooperates with other parenchymal cells to maintain homeostasis. Disruption of this exquisite machinery leads to inflammation. For example, alveolar macrophages migrate from alveolus to alveolus clearing debris and disruption of this process recruits neutrophils to induce acute inflammation. In liver, Kupffer cells reach out of their vascular niche and communicate with hepatocytes, endothelium and stellate cells. Fibrosis forms walls between Kupffer cells and other cells and causes these specialized macrophages to lose their contacts with other cells and as such lose their identity leading to recruitment of monocytes. Regardless of tissue, the immune cells contribute to homeostasis and their perturbation leads to inflammation.

08:30-09:30
Plenary lecture: Taming inflammation to treat infection
Dr. Mauro Teixeira, Federal University of Minas Gerais, Brazil

An adequate inflammatory response is necessary to control infection acutely and to prime the immune system for an adequate adaptive immune response. However, an altered inflammatory response during infection may cause tissue damage that is frequently accompanied by significant disease and eventually death. We have recently found that mediators of resolution of inflammation are produced during the course of various severe infections and control the inflammatory response in such a way as to prevent tissue damage but allowing adequate acute and adaptive immune responses. Indeed, in the absence of receptors for pro-resolving molecules - such as in FPR2-deficient mice - inflammation during bacterial or viral infections is enhanced. This is not accompanied by better control of infection but by tissue damage and dysfunction. On the other hand, administration of pro-resolving molecules, such as angiotensin 1-7 or annexin-A1, is associated with decreased inflammatory response in models of viral (influenza, dengue and coronavirus) and bacterial infections. We will discuss potential mechanisms associated with beneficial effects during infection and the potential for the development of these drugs for the adjunct treatment of infectious diseases.

08:30-09:30
Plenary lecture: Microbiota and intestinal inflammation
Pr. Harry Sokol, Saint-Antoine Hospital, Ap-HP, France

The pathogenesis of inflammatory bowel disease (IBD) is related to an activation of the gastrointestinal immune system towards the gut microbiota in genetically susceptible hosts and under the influence of environmental factors. The microbial community of the human gastrointestinal tract is fundamental to health and is influenced by environmental and genetic factors. The loss of the delicate balance of this complex ecosystem, called dysbiosis, is implicated in many diseases, including IBD. IBD patients show an altered composition of the gut microbiota, with notably a decrease in the abundance of anti-inflammatory bacteria such as Faecalibacterium prausnitzii. Besides changes in composition, many microbiota functions are altered in IBD. These data are now converted into new biomarkers and treatments.
