New Paper: Patrolling Alveolar Macrophages Conceal Bacteria from the Immune System to Maintain Homeostasis

In vivo live imaging of alveolar macrophages.

Congratulations to our Platform 1 Co-Lead Dr. Paul Kubes on this recent publication! Using in vivo live imaging of infected lungs in animal models, Dr. Kubes‘ team and colleagues show that alveolar macrophages patrol the airways and capture inhaled bacteria, but their migration is impaired during viral infection. Their discoveries highlight the importance of finding […]

New Paper: Programing of an Intravascular Immune Firewall by the Gut Microbiota Protects against Pathogen Dissemination during Infection

Cell-illustration-Braedon-August202

Congratulations to our Director and Platform 1 Lead Dr. Kathy McCoy, as well as our Education & Mentorship Lead & Co-Lead Dr. Markus Geuking and Dr. Braedon McDonald, on this recent publication! Summary Eradication of pathogens from the bloodstream is critical to prevent disseminated infections and sepsis. Kupffer cells in the liver form an intravascular […]

New Paper: Role of IRF8 in immune cells functions, protection against infections, and susceptibility to inflammatory diseases.

Study finds that artificially sweetened beverages consumption during pregnancy impacts mother’s microbiota and might lead to higher infant BMI.
