Researchers explore how patients with a rare and severe immunodeficiency were still able to defend themselves normally against viruses, including COVID-19
The first study of humans with a rare immunodeficiency reveals how the immune system protects the body against pathogens known to cause serious diseases, such as tuberculosis and COVID-19. The research involving McGill University, paves the way for new therapies to treat autoimmune diseases, chronic inflammatory diseases, and new approaches to vaccine development.
The immune system responds differently to various types of pathogens, like bacteria, parasites, and viruses. However, scientists are still trying to uncover how this complex network functions together and the processes that can go wrong with immunodeficiencies.
“The immune system plays a vital role in protecting the body from harmful germs that make people ill. It’s made up of a complex network of organs, cells, and proteins – like IRF1 or regulatory factor 1, which is key in the regulation of an early immune response to pathogens,” says co-author of the study David Langlais, an Assistant Professor in the Departments of Human Genetics and Microbiology and Immunology at McGill University.
