Ectopic expression of cGAS in enhances STING-mediated IFN-β response in human macrophages and dendritic cells.

Background: Interferon (IFN)-β induction via activation of the stimulator of interferon genes (STING) pathway has shown promising results in tumor models. STING is activated by cyclic dinucleotides such as cyclic GMP-AMP dinucleotides with phosphodiester linkages 2'-5' and 3'-5' (cGAMPs), that are produced by cyclic GMP-AMP synthetase (cGAS). However, delivery of STING pathway agonists to the tumor site is a challenge.

Surface Labeling with Adhesion Protein FimH Improves Binding of Immunotherapeutic Agent Ty21a to the Bladder Epithelium.

Background: Bladder cancer is the ninth most common cancer in men. 70% of these tumors are classified as non-muscle invasive bladder cancer and those patients receive 6 intravesical instillations with BCG after transurethral resection. However, 30% of patients show recurrences after treatment and experience severe side effects that often lead to therapy discontinuation.

The Chemokine Receptor CX3CR1 Defines Three Antigen-Experienced CD8 T Cell Subsets with Distinct Roles in Immune Surveillance and Homeostasis.

Infections induce pathogen-specific T cell differentiation into diverse effectors (Teff) that give rise to memory (Tmem) subsets. The cell-fate decisions and lineage relationships that underlie these transitions are poorly understood. Here, we found that the chemokine receptor CX3CR1 identifies three distinct CD8 Teff and Tmem subsets.
