A study led by David Sancho at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) in Madrid reveals how an increase in intestinal permeability allows the natural gut bacteria to cross the intestinal barrier and reach the bone marrow, where they induce epigenetic changes-modifications that alter gene activity without affecting DNA sequence-in the stem cells that … Read more
Researchers at Karolinska Institutet and the Astrid Lindgren Children’s Hospital in Sweden have determined how children’s immune systems react to different kinds of cancer depending on their age. The study, which is published in the journal Cell, reveals significant differences between the immune response of children and adults, and has the potential to lead to … Read more
A new paper by a team of Concordia researchers from the departments of Biology and Physics proposes a novel method of fighting cancer tumors that uses ultrasound-guided microbubbles – a technology already widely used in medical imaging and drug delivery. Writing in the journal Frontiers in Immunology, the researchers describe a process that uses ultrasound to modify the behavior of … Read more
Most people who get the seasonal influenza vaccine – which contains strains of viruses from distinct virus subtypes – mount a strong immune response to one strain, leaving them vulnerable to infection by the others, and researchers have long wondered what impacts such variable responses more – host genetics or prior exposure to virus strains. … Read more
The seasonal influenza vaccine contains strains of viruses from distinct virus subtypes, but most people who are vaccinated will mount a strong immune response to one strain, leaving them vulnerable to infection by the others. Researchers have long wondered whether host genetics or prior exposure to virus strains impacts more on these variable responses. A … Read more
