Tracheal terminal cells of Drosophila are immune privileged to maintain their Foxo-dependent structural plasticity
Respiratory organs must balance their primary function of gas exchange with the constant threat of inhaled pathogens. In the Drosophila tracheal system, gas exchange occurs at the tracheal terminal cells (TTCs), the functional equivalents of mammalian alveoli. While bacterial infection triggers a robust innate immune response throughout the broader airway ep
