A: Representative images of immunostaining for cGAS, STING, CD31, and CD11b in retinal cryosections of room air (RA) controls and OIR mice at P17. The white arrows indicated the cGAS and STING staining co-localized with CD11b staining. WebApr 11, 2024 · cGAS-STING-mediated DNA sensing is demonstrated to be critical for launching antitumor immunity. However, DNA-based cGAS-STING agonists are rarely reported owing to low cell permeability, poor biostability and, especially, limited length of exogenous DNA. Here, we present a virus-like particle which is self-assembled from long …

WebThe cGAS-STING pathway is important in microbial infection, autoimmune diseases, and cancer (Tao et al. 2016). DNA within the cytosol can be an indicator of pathogen invasion and is sensed by cyclic GMP-AMP synthase (cGAS). Mitochondrial DNA (mtDNA) can also serve as a cGAS ligand in a certain context (Ma et al. 2024). WebFurther, the cGAS‐STING pathway is known to be involved in the immune response to intracytoplasmic DNA. 23 Therefore, we generated STING KO cells using the CRISPR‐Cas9 system in NCI‐H292 cells. STING KO was confirmed to be devoid of STING at both the genomic DNA and protein levels (Figure S2A,B ).
WebIn addition, activation of the cGAS-STING pathway was also found after adding LPS for 2 h, as cGAS, Pho-TBK1, and Pho-IRF3 levels were increased significantly (Figure 2B and C). We next transfected HESCs with small interfering RNA STING or the negative control and detected the aforementioned inflammatory factors after LPS stimulation.
