This study presents the development of a humanized β₂ integrin Knockin mouse model, where the human ITGB2 gene replaces the mouse Itgb2 gene. This model enables in vivo visualization of β₂ integrin activation using conformation-specific antibodies (KIM127 and mAb24). Utilizing this model, researchers observed localized β₂ integrin activation at the rear of arresting neutrophils in inflamed venules and during systemic inflammation, providing insights into neutrophil adhesion dynamics and integrin activation patterns in vivo.
The humanized ITGB2 Knockin mouse model enables real-time visualization of β₂ integrin activation in neutrophils during inflammation, revealing spatially localized activation patterns critical for neutrophil adhesion and migration.
