TRAF3 gene regulates macrophage migration and activation by lung epithelial cells infected with Aspergillus fumigatus

can infect immunocompromised individuals and cause chronic and fatal invasive fungal infections. A better understanding of the molecular mechanisms of -host interactions may provide new references for disease treatment. In this study, we demonstrated that the TRAF3 gene plays an important role in the early infection of by regulating the resistance of lung epithelial cells to . Macrophages are the most abundant innate immune cells in the alveoli; however, few studies have reported on the interactions between lung epithelial cells and macrophages in response to invasion. In our study, it was demonstrated that the TRAF3 gene reduces migration to macrophages and cytokine production by negatively regulating lung epithelial cell adhesion and internalization of spores. Together, our results provide new insights into lung epithelial cell-macrophage interactions during infection.
