Detection of pre-existing immunity to bacterial Cas9 proteins in people with cystic fibrosis Abstract. Cystic fibrosis (CF) is caused by homozygous mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, resulting in multi

Researchers sought to determine if pre-existing immunity to Cas9 from S. aureus or S. pyogenes was present or augmented in people with cystic fibrosis (CF), as a cure for #CF will likely require a gene therapy approach. Learn more in ImmunoHorizons: ow.ly/9MUj50XsYlK.

Tumor cells upregulate CCL22 in a STING-dependent manner in response to paracrine factors released by STING-activated myeloid cells and type I interferons Abstract. Immunosuppressive elements within the tumor microenvironment include both regulatory T cells (Tregs) and M2 macrophages. A well-described mechani

Researchers found that exogenous type I interferons, a major downstream product of STING activation, also upregulate CCL22 in cancer cells via a STING-dependent mechanism and that exogenous IFN-β can directly activate STING. Learn more in ImmunoHorizons: ow.ly/C11i50Xmw7h

LIGHT in combination with IL-13 or IL-17 drives inflammatory transcriptional signatures in human pulmonary fibroblasts relevant for human lung disease Abstract. Fibroblasts are structural cells primarily involved in tissue remodeling, but recent single-cell RNA sequencing (RNA-seq) transcriptomic data hav

The synergistic activity of LIGHT with other classical cytokines was observed to regulate transcription in pulmonary fibroblasts and suggests the involvement of LIGHT in shaping fibroblast phenotypes observed in chronic lung disease.

STING agonists differentially upregulate CCL22 and IFNβ. HeLa (A–D) and MCF7 cells (E–H) were treated with 30 μM of each indicated STING agonist or DMSO vehicle control (for diABZI) for 24 hours, then harvested in TRIzol for RNA purification and RT-qPCR using TaqMan assays for CCL22 or IFNβ. Error bars represent SDs of independent biological replicates. Statistical analyses were performed on log-transformed data using unpaired, 2-tailed t tests except for (C) and (G), which were analyzed with a one-way ANOVA and Šídák multiple comparisons test. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001; ns, not significant.
