Nature Reviews Immunology Poster on innate immunity: sensing and
signalling
The innate immune system is the first line of defence against invading
pathogens. Detection of such pathogens is a complex business, involving
several families of pattern-recognition receptors and an array of
signalling molecules.
This poster provides an overview of the components and networks
involved in pathogen sensing and signalling in the innate immune system.

The genome of the model beetle and pest Tribolium castaneum p949
The beetle Tribolium castaneum is a commonly used laboratory model, combining
the ease of systematic RNAi experiments like those in Caenorhabditis elegans,
with biology that is more representative of most insects than Drosophila
melanogaster. A large consortium has sequenced and analysed the genome
of the red flour beetle, creating a resource for biologists everywhere.

Lateral presynaptic inhibition mediates gain control in an olfactory circuit p956
A study that combines in vivo systems neuroscience with synaptic physiology
and Drosophila genetics identifies a presynaptic form of lateral inhibition
in the olfactory system. The mechanism allows for a flexible form of gain
control, which promotes coding efficiency when stimuli are strong and unambiguous,
but maximizes sensitivity when stimuli are weak and ambiguous.

Crystal structures of DNA/RNA repair enzymes AlkB and ABH2 bound to dsDNA pp961-965
Base lesions can be directly repaired by oxidative dealkylation
catalysed by AlkB in bacteria and by ABH2/ABH3 in man. Several
structures of AlkB and ABH2 bound to dsDNA are solved. These structures
reveal why AlkB prefers ssDNA to dsDNA substrates, and how ABH2 differs
structurally, to allow it to repair dsDNA.

The inner jet of an active galactic nucleus as revealed by a radio-to-gamma-ray outburst pp966-969
Sequences of high-resolution radio images and optical polarization
measurements of the blazar BL Lacertae are reported. The data reveal
a bright feature in the jet that causes a double flare of radiation
from optical frequencies to TeV gamma-ray energies. It is concluded
that the event starts in a region with a helical magnetic field as
envisaged by the theories.

A topological Dirac insulator in a quantum spin Hall phase pp970-974
In the conventional quantum Hall effect, a two-dimensional electronic
system in the presence of a magnetic field forms metallic conduction
paths at the edge of the sample. This paper experimentally demonstrates
a sought-after three-dimensional and spontaneous version of this effect;
the bulk of a Bi0.9Sb0.1 crystal is shown to be insulating, while
two-dimensional metallic conduction paths exist at the surface, without
any applied magnetic field.

Small phonon contribution to the photoemission kink in the copper oxide superconductors pp975-978
This paper reports first-principles calculations of the role of phonons
in La2-xSrxCuO4 (LSCO). It is demonstrated that the phonon-induced
renormalization of the electron energies and the Fermi velocity is
almost one order of magnitude smaller than the effect observed in
photoemission experiments. Therefore the present finding rules out
electron-phonon interaction in bulk LSCO as the exclusive origin
of the measured kink.

Eocene/Oligocene ocean de-acidification linked to Antarctic glaciation by sea-level fall pp979-982
A global biogeochemical box model is used to test competing hypotheses
put forward to explain the Eocene/Oligocene transition. It is found that
only shelf-to-deep-sea carbonate partitioning is capable of explaining
the observed changes in both carbon isotope composition and calcium carbonate
accumulation at the sea floor. This work sheds new light on the mechanisms
linking glaciation and ocean acidity change across the climate transition of
the Cenozoic.

Hydrous silicate melt at high pressure pp983-986
The results of first-principles molecular dynamics simulations of hydrous
silicate melt is reported, showing that pressure has a profound influence
on speciation of the water component. It is inferred that the
speciation changes from being dominated by hydroxyls and water molecules
at low pressure to extended structures at high pressure. This change in
structure is linked to the finding that the water-silicate system becomes
increasingly ideal at high pressure, indicating complete miscibility of
water and silicate melt throughout almost the entire mantle pressure regime.

It is reported that the current severe outbreak of the mountain pine

Genetic variation in human NPY expression affects stress response and emotion p997-1001
Across human populations, individual ability to deal with stress and anxiety
spans a wide range. The causes of emotional resilience are complex; this paper
shows the contribution of genetic variance in expression of neuropeptide Y (NPY),
an anxiolytic peptide released in emotion related neural circuitry. Genetic
variants were predictive of not only NPY levels, but also fMRI and PET
activation in response to emotional stimuli and pain induced stress.

Insect olfactory receptors are heteromeric ligand-gated ion channels p1002-1006
Olfactory cues are detected by large families of seven transmembrane
spanning receptors, which have until now been classified as G-protein
coupled receptors. In insects, these odorant receptors require a second
protein (Or83b) for correct function. These heteromeric receptors form
ligand gated cation channels that are not dependent on G protein coupled
second messengers and it is speculated that seven other transmembrane
spanning proteins may show similar ion channel activity.

Olfactory cues are detected by large families of seven transmembrane

Upper intestinal lipids trigger a gut–-brain–-liver axis to regulate glucose production p1012-1016
The presence of lipids in the intestine causes a reduction in nutrient
intake, but it is now shown that lipids present in the intestine also
regulate endogenous nutrient production. According to the data, putative
intra intestinal lipid sensors signal the presence of ingested lipids,
via the brain, to the liver, which reduces the endogenous glucose
production accordingly.

A deadenylation negative feedback mechanism governs meiotic metaphase arrest p1017-1021
A genome wide screen for mRNAs that were polyadenylated at meiotic
transitionsnoted that many contained an ARE, a deadenylation element,
as well as a cytoplasmic polyadenylation element (CPE). One such mRNA
encodes C3H 4, a protein that promotes shortening of polyA tails. The
data suggest a model in which the early extension of polyadenylation
through the CPE element leads to expression of C3H 4, which then acts
in a negative feedback loop to deadenylate, and deactivate, those mRNAs
that also contain an ARE, thereby allowing exit from metaphase.
