WebBacterial colonization of the airways is a feature of COPD. 3,4 There are a variety of possible underlying causes for this, including defective phagocytosis by COPD macrophages allowing persistence of bacteria. 5 Bacterial colonization may lead to chronic stimulation of immune cells through Toll-like receptors (TLRs) which sense pathogen … WebThe innate immune system in drosophila and mammals senses the invasion of microorganisms using the family of Toll receptors, stimulation of which initiates a range of host defense mechanisms. In drosophila antimicrobial responses rely on two signaling pathways: the Toll pathway and the IMD pathway.
