Prefa ce
The last decade has completely changed our understanding of pathogen recognition in
terms of how the innate immune system manages to integrate molecular patterns of com-
pletely different pathogens into rather uniform innate immune responses. This immunos-
timulatory effect of pathogen-derived nucleic acids is of great importance for host defense
as it not only initiates an immediate innate immune response but also serves as an adjuvant
for the priming of adaptive immune responses that rapidly combat the pathogen upon sub-
sequent exposures. This mechanism renders nucleic acid-based adjuvants interesting com-
pounds for vaccination strategies. Although the structures of nucleic acids are strongly
preserved from prokaryotes to mammals, the mammalian immune system has found ways
to distinguish own nucleic acids from those of bacteria and viruses. This is necessary for
immune tolerance and it is supported by compartmentalization of nucleic acids away from
nucleic acid sensors, by epigenetic DNA and RNA modifi cations, by rapid opsonization of
extracellular nuclear particles and their phagocytic clearance by macrophages. However,
unfortunate combinations of genetic variants or certain drugs can compromise these pro-
tective mechanisms. This can turn tolerogenic autoantigen presentation into aberrant acti-
vation and proliferation of auto-reactive lymphocytes, with ensuing production of
antinuclear antibodies and induction of autoimmune diseases like systemic lupus erythema-
tosus and scleroderma.
The biological signifi cance of nucleic acid immune recognition is not limited to host
defense, vaccination, and autoimmunity. The diagnostic and therapeutic use of gene target-
ing nucleic acids, e.g., siRNAs, miRNAs, or aptamers, has to consider the immunostimula-
tory potential of certain nucleic acid formats. This implies either to avoid immune
stimulation in therapeutic gene regulation with siRNA or aptamers, or to utilize immune
stimulation to overcome tumor-associated immunosuppression, e.g., by the use of bifunc-
tional siRNAs that combine a knock-down sequence with immunostimulatory structural
features in one molecule.
This edition of Methods in Molecular Biology presents validated experimental strategies
to dissect nucleic acid sensing in vitro and in vivo. It is meant as a resource for immunologists,
molecular biologists, virologists, microbiologists, and any researcher that wants to know how
the innate immune system handles nucleic acids from endogenous or foreign sources.
