WebNov 5, 2024 · TLR9 recognizes guanine-cytosine–rich DNA from pathogens and self-DNA as well as the short single-stranded synthetic DNA 5′-cytosine-phosphate-guanine-3′ (CpG) ( 15, 16 ). TLR9 stimulation induces downstream signaling, leading to the induction of a range of cytokines and the promotion or suppression of cell survival ( 17, 18 ). WebTLR9 is localized in intracellular vesicles of the ER, lysosomes, and endosomes of resting cells. DNA recognition by TLR9 occurs after transport to endolysosomes, which is … final cut pro webm

WebJul 21, 2024 · TLR9 localizes in the ER in multiple cell types, including macrophages, B cells, dendritic cells, and plasma cells [ 34 ]. After uptake of the ligands by phagocytosis, TLR9 immediately redistributes from the ER to the CpG DNA-containing structures. TLR9 is expressed at high levels on monocytes of ENL patients, and is positively linked to the secretion of proinflammatory cytokines TNF, IL-6, and IL-1β. TLR9 agonists and antagonists may be useful in treatment of a variety of inflammatory conditions, and research in this area is active.
