But this essential act also means we inhale microorganisms, particles, and pollutants. A new study from the Research Institute of the 海外直播b站 Health Centre (RI-MUHC) has revealed how the unique immune cells that are developed in the embryo protect our lungs from environmental challenges throughout the course of our lifetime.</p> Thu, 02 Feb 2023 14:55:51 +0000 claire.loewen@mcgill.ca 289178 at /newsroom /newsroom/maziar-divangahi Thu, 17 Dec 2020 21:08:53 +0000 frederique.mazerolle@mcgill.ca 253667 at /newsroom /newsroom/channels/news/canadian-researchers-promising-path-towards-developing-flu-treatment-using-lipid-target-297368 <p>For most people, the influenza A virus (IAV), commonly known as the flu, is cleared from the body by our own immune system. In some cases, however, the immune response becomes dysregulated and if left uncontrolled, the inflammation caused by our own immune cells can lead to extensive lung tissue damage and enhanced morbidity and mortality.</p> <p>How can we help our immune system to balance the two main host defense strategies: attacking pathogens (called <i>host resistance</i>) and preserving our own tissue (called <i>disease tolerance</i>)?</p> Wed, 22 May 2019 15:59:07 +0000 justin.dupuis@mcgill.ca 164227 at /newsroom /newsroom/channels/news/anti-tb-drugs-can-increase-risk-tb-re-infection-295658 <p>Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by <i>Mycobacterium tuberculosis (Mtb).</i> They don鈥檛, however, always prevent reinfection. Why this happens is one of the long-standing questions in TB research.</p> Fri, 22 Mar 2019 17:56:54 +0000 justin.dupuis@mcgill.ca 153422 at /newsroom /newsroom/channels/news/beyond-killing-tuberculosis-287156 <p>Historically, our view of host defense against infection was that we must eliminate pathogens to eradicate disease. However, this perspective has recently been challenged as scientists have taken a lesson from plant biologists about an ancient strategy involving the ability to 鈥渢olerate鈥� rather than 鈥渞esist鈥� infection to maintain health. This concept, referred to as 鈥渄isease tolerance鈥�, provides an opportunity to develop new strategies that mitigate the consequences of infection.</p> Fri, 11 May 2018 19:03:57 +0000 justin.dupuis@mcgill.ca 39879 at /newsroom /newsroom/channels/news/meet-ripk3-good-cop-bad-cop-all-one-285090 <p><span>Each year, influenza kills half a million people globally with the elderly and very young most often the victims.
