To learn a little more about our research, see this video produced by the Research to Reality social media campaign.The following is a selection of featured events from 's self-submitting events calendar along with selected events from the city's event listings. We are always interested in hearing from motivated researchers who are interested in a career in infectious disease research. We aim to be a resource to our colleagues and to train highly motivated students and post-docs to become world class scientists. The work in our lab is creative, innovative, ambitious and c ollaborative. To do this we aspire to understand both the basic molecular and cellular biology of host-pathogen interactions, to utilize novel human models of disease and to find novel ways of translating our work into potential immunotherapies. The long term goal of our work is to make major advances in our understanding of host defence against infectious disease. As such we have access to the state of the art facilities at McMaster including the Human Immune Testing Suite and the R.E. We are part of the Department of Medicine in the Faculty of Health Sciences and the Institute for Infectious Disease Research and the McMaster Immunology Research Centre. DeGroote Centre for Learning & Discovery at McMaster University in Hamilton, Ontario, Canada. For more detailed descriptions of the research going on in the Bowdish lab see the “Current Projects” page. Research interests in the Bowdish lab including 1) understanding how macrophage phagocytosis changes with age and during acute and chronic inflammation, particularly in response to the pulmonary pathogen Streptococcus pneumoniae, 2) determining how age-associated inflammation changes monocyte/macrophage development and function and increases susceptibility to infection and 3) elucidating how age-associated inflammation changes immune function and alters the aging trajectory, and 4) understanding how the microbiota contributes to healthy or unhealthy aging and how microbiome-host interactions can be harnessed to prevent infections. Because the macrophage’s ability to “eat” pathogens (called ‘phagocytosis’) is crucial to this initial interaction with pathogens and shapes the downstream immune response, factors that alter the rate or magnitude of phagocytosis can have profound effects on an individual’s susceptibility to infection. In some cases a frustrated attempt to resolve infection or an inappropriate response to non-infectious stimuli can result in tissue damage and sterile inflammation. Generally they are effective in clearing the pathogen without mounting an inflammatory response however, when a pathogen evades detection or clearance they are instrumental in mobilizing an appropriate immune response. Macrophages are the sentinel cells of the immune response their role is to detect pathogens through receptors on their surface. Specialized white blood cells called macrophages are particularly important in protecting us from potential invaders. The innate component of our immune system consists of white blood cells that circulate in our blood or live in our tissues and are on constant patrol for invading organisms. Even our natural microbiota harbours potential pathogens and yet we are healthy most of the time. Potential pathogens are in the air we breathe, the things we touch, and the food we eat. Humans are exposed to potentially dangerous microorganisms every moment of every day.
