This video demonstrates intranasal BCG immunization in mice, activating both innate and adaptive immune responses, leading to the development of lung-resident memory T cells and effector B cells, thus enhancing protection against Mycobacterium infections.
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
