Distinct nociceptor roles in inflammation and itch revealed by subset-specific transcriptomic adaptation

ABSTRACT: This study identifies two distinct subsets of sensory neurons that separately regulate itch and inflammation in allergic contact dermatitis. MrgprD⁺ nonpeptidergic neurons adopt a transient regenerative program during inflammation and are essential for itch behavior, while Trpv1⁺ peptidergic neurons limit inflammation by restraining neutrophil infiltration. These findings uncover parallel, nonredundant neuronal circuits that independently control inflammatory and pruritic responses in the skin.

Tmem45b Modulates itch via Endoplasmic Reticulum Calcium Regulation

Project description:Chronic itch is detected by dorsal root ganglia (DRG) that severely impairs quality of life. However, its underlying mechanisms remain poorly understood. We identified that Tmem45b was contained in natriuretic peptide type B (Nppb)-, mas-related G-protein coupled receptor member A3 (Mrgpra3)-, and Mrgprd-positive DRG neurons, which are associated with itch sensation. The role of Tmem45b in itch sensation has not been explored. Tmem45b conditional knockout (cKO) mice exhibited decreased scratching to β-alanine, and increased scratching to chloroquine. Notably, Tmem45b cKO alleviated chronic itch. Furthermore, Tmem45b cKO impaired the calcium response to β-alanine and allyl isothiocyanate but not to chloroquine in dissociated DRG neurons. Tmem45b deficiency led to significant downregulation of sarco/endoplasmic reticulum calcium transport ATPase 1 (Serca1), impairing calcium storage capacity of endoplasmic reticulum (ER). Inhibition of Serca1 in DRG neurons reduced intracellular calcium release triggered by β-alanine and chloroquine. Together,Tmem45b deficiency may reduce nonhistaminergic itch and disrupt ER calcium regulation, highlighting a potential target for chronic itch therapy.

iPSC-derived human sensory neurons reveal a subset of TRPV1 antagonists as anti-pruritic compounds

Project description:Given the inaccessibility of human sensory neurons (SNs), it is yet to be established whether the signalling pathway between histamine 1 receptor (H1R) and transient receptor potential cation channel subfamily V member 1 (TRPV1) is conserved between humans and mammalian models. Accessible human SNs are vital for identifying TRPV1 antagonists with higher potential for success in clinical trials targeting histaminergic itch, especially given TRPV1's species specificity concerns. Hence to build a humanized histamine-dependent itch model, we derived peripheral sensory neurons from human pluripotent stem cells (hiPSC-SNs) and validated channel functionality using immunostaining, calcium imaging and multielectrode array (MEA) recordings. Here, we demonstrated that a subset of hiPSC-SNs exhibits co-expression of H1R and TRPV1, responding to both histamine and capsaicin agonists. We found that inhibiting TRPV1 prevented histamine activation. Moreover, we show that silencing histamine-sensitive neurons reduces capsaicin response, and silencing capsaicin-sensitive neurons diminishes histamine response. To assess the ability of hiPSC-SNs in TRPV1 antagonist drug screening, we evaluated two well-established hyperthermic and three thermal-neutral TRPV1 antagonists. Our finding identifies SB366791, a thermal-neutral antagonist, as a potent inhibitor of H1R activation. The use of hiPSC-SNs may therefore provide a physiologically relevant means to perform large-scale screening to discover anti-pruritic agents predictive of actual efficacy in human clinical trials.

Neuronal BST2: A Pruritic Mediator alongside Protease-Activated Receptor 2 in the IL-27–Driven Itch Pathway

Project description:In the present study, RNA-seq were performed To explore biological significance of IL-27 and BST2 in the neuro-cutaneous signaling network of chronic itch. mRNA profiles were generated by deep sequencing, in triplicate, using MGISEQ-2000. We found that both human keratinocytes and murine sensory neurons responded to IL-27 and BST2, resulting in enrichment of genes promoting itch and inflammation. IL-27-BST2 signaling pathway activation promotes cutaneous inflammation and itch, both leading into an aggravation of AD. This finding might help us to better understand the immune-neuro-modulatory mechanism in itch circuits

PLAUR-TLR2 Axis Promotes Chronic Itch

Project description:In the present study, RNA-seq were performed To identify clinical relevance of PLAUR, a putative Serpin E1 receptor, in cutaneous itch signaling and crosstalk pathways with other critical itch modulators.mRNA profiles were generated by deep sequencing, in triplicate, using MGISEQ-2000. Our experiment showed Serpin E1-treatment further led to a marked upregulation of TLR2 transcript in mDRG neurons, along with enhanced transcription of cosignaling proteins belonging to pro-inflammatory signaling pathways including NF-κB signaling proteins. We next investigated the consequence of TLR2 activation in mTGNs using the TLR agonists, Pam3CSK4 (TLR1/2 agonist), FSL-1 (TLR2/6 agonist), or vehicle. Among these transcripts, TLR2 was found upregulated strongest by both TLR2 agonists suggesting a selfenhancing feedback loop of TLR2 activation.The PLAUR-TLR2 axis promotes cutaneous inflammation and itch, both feeding into an aggravation of AD. This finding might help us to better understand the skin-nerve communication in itch circuits.

Nppb Neurons Are Sensors Of Mast Cell-Induced Itch

Project description:Itch is an unpleasant skin sensation which can be triggered by exposure to many chemicals including those released by mast cells. The Nppb-expressing class of sensory neurons when activated elicit scratching responses in mice, however, it is unclear which itch-inducing agents stimulate these cells and the receptors involved. Here, we identify receptors expressed by Nppb-neurons and demonstrate the functional importance of these receptors as sensors of endogenous pruritogens released by mast cells. Our search for receptors in Nppb-neurons revealed that they express leukotriene, serotonin, and sphingosine-1-phosphate receptors. Targeted cell ablation, calcium imaging of primary sensory neurons, and conditional receptor knockout studies demonstrate that these receptors induce itch by the direct stimulation of Nppb-neurons and neurotransmission through the canonical GRP-dependent spinal cord itch pathway. Together our results define a molecular and cellular pathway for mast cell-induced itch.

Nonpeptidergic MrgprD-expressing neurons maintain cutaneous homeostasis via glutamate-mediated mast cell suppression

Project description:Cutaneous mast cells (MC) mediate numerous skin inflammatory processes and have anatomical and functional associations with sensory afferent neurons. We found that Langerhans cell (LC)-deficient mice have reduced numbers of MrgprD-expressing epidermal nerve endings and manifest enhanced irritant dermatitis due to exaggerated MC degranulation. Ablation of LC or MrgprD-expressing neurons increased expression of a MC gene module including the activating receptor, Mrgprb2, resulting in increased MC degranulation and cutaneous inflammation in multiple models. β-alanine agonism of MrgprD-expressing neurons reduced expression of MC module genes and suppressed MC responses. MrgprD-expressing neurons released glutamate which was increased by MrgprD agonism and decreased in LC-deficient mice. Inhibiting glutamate release or glutamate receptor binding yielded hyperresponsive MC and a genomic state similar to that in mice lacking MrgprD-expressing neurons. These data demonstrate that MrgprD-expressing neurons suppress MC hyperresponsiveness and skin inflammation via glutamate release thereby revealing an unexpected neuro-immune mechanism maintaining cutaneous immune homeostasis.

Project description:The dorsal root ganglion (DRG) neurons take in charge of primary detection and transmission of peripheral pain and itch stimuli, however, as two distinct noxious sensation, it is still attractive for this field that how the DRG neurons differentially response and code pain and itch. Here, we investigate the response and activation spectrum of DRG neurons under peripheral pain and itch stimuli using in vivo two-photon calcium imaging, and find differences in the responsive intensity to pain and itch between multisensory neurons (both pain and itch) and single-sensory neurons (either pain or itch). Besides, single-cell RNA sequencing (scRNA-seq) is used to reveal the heterogeneity of distinct subpopulations based on their expression of pain- or itch-related marker genes and indicates the similarity and difference of their transcriptomic changes under chronic pain and itch. Our results will provide fundamental insights to the peripheral pain and itch differential coding mechanism, moreover, benefit the development of pain and itch therapies.
