Cell intrinsic immunity spreads to bystander cells via the intercellular transfer of cGAMP

Andrea Ablasser

The innate immune defence of multicellular organisms against microbial pathogens requires cellular collaboration. Information exchange allowing immune cells to collaborate is generally attributed to soluble protein factors secreted by pathogen-sensing cell ...

Structural mechanism of cytosolic DNA sensing by cGAS

Andrea Ablasser

Cytosolic DNA arising from intracellular bacterial or viral infections is a powerful pathogen-associated molecular pattern (PAMP) that leads to innate immune host defence by the production of type I interferon and inflammatory cytokines. Recognition of cyt ...

cGAS produces a 2'-5'-linked cyclic dinucleotide second messenger that activates STING

Andrea Ablasser

Detection of cytoplasmic DNA represents one of the most fundamental mechanisms of the innate immune system to sense the presence of microbial pathogens. Moreover, erroneous detection of endogenous DNA by the same sensing mechanisms has an important pathoph ...

Nucleic acid driven sterile inflammation

Andrea Ablasser

The etiology of sterile inflammatory conditions is complex and affected by a variety of genetic, environmental and stochastic factors. But despite this overt complexity, progress has been made in elucidating mechanisms underlying disease pathogenesis. An i ...

Self-priming determines high type I IFN production by plasmacytoid dendritic cells

Andrea Ablasser

Plasmacytoid dendritic cells (pDCs) are responsible for the robust and immediate production of type I IFNs during viral infection. pDCs employ TLR7 and TLR9 to detect RNA and CpG motifs present in microbial genomes. CpG-A was the first synthetic stimulus a ...

Species-specific detection of the antiviral small-molecule compound CMA by STING

Andrea Ablasser

Extensive research on antiviral small molecules starting in the early 1970s has led to the identification of 10-carboxymethyl-9-acridanone (CMA) as a potent type I interferon (IFN) inducer. Up to date, the mode of action of this antiviral molecule has rema ...

DNA sensing unchained

Andrea Ablasser

In two recent reports in Science, James Chen and colleagues provide compelling evidence that detection of cytosolic DNA triggers the production of a novel second messenger, cyclic GMP-AMP (cGAMP), which in turn activates a signaling pathway that induces ty ...

Induction of type I IFNs by intracellular DNA-sensing pathways

Andrea Ablasser

A successful antimicrobial immune response involves the coordinate action of cells and soluble factors, with the cytokine family of type I interferons (IFNs) having a central role. Type I IFNs are not only crucial in conferring immediate antimicrobial, mos ...

Inflammasomes: current understanding and open questions

Andrea Ablasser

The innate immune system relies on its capability to detect invading microbes, tissue damage, or stress via evolutionarily conserved receptors. The nucleotide-binding domain leucine-rich repeat (NLR)-containing family of pattern recognition receptors inclu ...

An unexpected role for RNA in the recognition of DNA by the innate immune system

Andrea Ablasser

A central function of our innate immune system is to sense microbial pathogens through the presence of their nucleic acid genomes or their transcriptional or replicative activity. In mammals, a receptor-based system is mainly responsible for the detection ...
