    Pain is a complex phenomenon involving not just the perception of pain, but also autonomic and motor responses. Here, the authors show that these different dimensions of pain are associated with distinct patterns of neural responses to noxious stimuli as measured using EEG.

    Ketamine is a short-acting analgesic that also has anti-depressant effects. Here the authors show in rat models of chronic pain that low-dose ketamine can induce an anti-aversive state that persists after the initial short term analgesia has ended.

    People vary in the extent to which they feel better after taking an inert, placebo, treatment, but the basis for individual placebo response is unclear. Here, the authors show how brain structural and functional variables, as well as personality traits, predict placebo response in those with chronic back pain.

    Systemic chronic hypoxia is a feature of many diseases and may influence the communication between bone marrow and gut microbiota. Here, the authors show that chronic hypoxia predisposes bone marrow stem cells to premature senescence, which may be due to gut dysbiosis and gut microbiota-derived d-galactose accumulation.

    It is known that descending facilitation of spinal responses may contribute to chronic pain, however many studies have focussed on brainstem mechanisms. Here the authors show that stimulation of the anterior cingulate cortex increases excitatory transmission in the dorsal horn, and that this may be via a direct pathway independent of the brainstem.

    There are several classes of sensory neuron that contribute to pain states. Here, the authors demonstrate that TrkB+ sensory neurons detect light touch under normal conditions in mice but contribute to hypersensitivity in models of chronic pain, and that ligand-guided laser ablation of TrkB+ sensory neurons in the mouse skin attenuates this hypersensitivity.

This study finds that semaphorin 4C and its receptor Plexin B are expressed in sensory neurons and are pronociceptive in a mouse model of inflammatory pain.

    Purinergic receptor activation by extracellular ATP in the dorsal horn contributes to neuropathic pain, but which cell types release ATP in this context is not known. The authors show in a mouse model of neuropathic pain that ATP is released by dorsal horn neurons, a process requiring the vesicular nucleotide transporter, VNUT.

    Microglia and monocytes contribute to neuropathic pain states, but the precise role of the two cell types is not clear. Here Peng et al. use temporally controlled ablation of monocytes and microglia in mice to show that these cells work together to initiate neuropathic-pain like behaviour, but are less important in the maintenance phase.

    The upregulation of TRP ion channels is implicated in pain processing. In this study, the authors show that the zinc-finger protein ZBTB20 is responsible for TRP channel upregulation, and eliminating ZBTB20 from pain-sensing neurons in mouse models of pain results in the reduction of pain-like sensation.

    TRPs are calcium-permeable channels involved in the sensing of damaging stimuli but the relationship between calcium influx and pain behaviour has been elusive. Here the authors find that the TRP channel OSM-9 functions as an ion channel in vivo in C. elegans, and establish residues that are critical for worm pain-like behaviour.

    Unravelling the relationships between disease symptoms and underlying molecular origins is an important task in biomedical research. Here, Zhou et al. link diseases via their symptom overlap, and show that similar phenotypes are mirrored in networks that connect diseases with common genes or protein interactions.

    C-fibre polymodal nociceptors in primates have been classified into two groups based on their sensitivity to mechanical stimuli. Here, Wooten et al. describe how the differences in the response speed of the receptors to stimuli suggest that these should be considered as three separate groups.

    Genetically identical twins provide a valuable resource to identify epigenetic factors associated with complex traits. Here the authors adopt this approach and find that differential methylation of the pain gene TRPA1 is associated with pain sensitivity in humans.

    Peptide drugs are attractive as therapeutics for gut-based applications, although they may be susceptible to reduction and degradation. Here, the authors develop seleno-oxytocin analogues, with enhanced stability at no cost to potency, and demonstrate their efficacy at colonic nociceptor inhibition in a mouse model.

    Gram-negative bacterial infections can often cause inflammation and pain. Meseguer et al. show that the inflammation and pain result from the direct activation of nociceptor TRPA1 channels by lipopolysaccharide, a major component of the outer membrane of Gram-negative bacteria.

    Opioid analgesic drugs act at opioid receptors to exert analgesic effects, but they also exert adverse side effects. In this study, the authors show that the TREK-1 potassium channel is responsible for mediating the analgesic effects of morphine but not the adverse side effects.

    Mechanical allodynia describes the process whereby innocuous stimuli is perceived as being noxious and is a common symptom of neuropathic pain. Using mice deficient in the cAMP sensor Epac1, the authors in this study find that Epac1 regulates mechanical allodynia by sensitizing the mechanotransducer Piezo2.

    Reorganization of the sensorimotor cortex due to loss of sensory input is implicated in phantom pain. Makin and colleagues use functional MRI to show that phantom pain experience is instead associated with maintained local functional and structural cortical representations but disrupted inter-regional connectivity.

    Mutations of the NaV1.7 voltage-gated sodium channel are implicated in abnormal pain signal transduction. Yang and colleagues perform structural modeling, mutant cycle analysis and electrophysiology on specific mutants and find that they can accurately predict their response profiles to channel blockers.

    The signalling cascade involved in lung ischaemia–reperfusion-induced oedema is poorly understood. Using knockout mice, Weissmann et al. propose a model in which reactive oxygen species production by endothelial NOX2 leads to phospholipase C-γ activation, DAG kinase inhibition and subsequent TRPC6 activation.

    TRPA1 is a key ion channel in pain signalling. This study shows that activation of TRPA1 in the spinal cord by acetaminophen metabolites and a non-electrophilic cannabinoid produces antinociception that is lost in mice lacking TRPA1, providing an explanation for the analgesic activity of acetaminophen.
