Pruritogenic Mediators and New Antipruritic Drugs in Atopic Dermatitis.

Atopic dermatitis (AD) is a common highly pruritic chronic inflammatory skin disorder affecting 5-20% of children worldwide, while the prevalence in adults varies from 7 to 10%. Patients with AD […]

The Eosinophil-to-Lymphocyte Ratio Acts as an Indicator for Improvement of Clinical Signs and Itch by Upadacitinib Treatment in Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic inflammatory skin disease with severe itch. The eosinophil-to-lymphocyte ratio (ELR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) are reported to reflect […]

Efficacy and safety of topical brepocitinib cream for mild-to-moderate chronic plaque psoriasis: a phase IIb, randomised, double-blind, vehicle-controlled, parallel-group study.

Plaque psoriasis (PsO) is an inflammatory skin disease driven, in part, by the activation of Janus kinase (JAK) signalling pathways.

Pain-related neuronal ensembles in the primary somatosensory cortex contribute to hyperalgesia and anxiety.

The mechanism by which acute pain or itch information at the periphery is processed in the primary somatosensory cortex (S1) remains unclear. To elucidate this, we used a viral-mediated targeted-recombination-in-active […]

MrgprA3-expressing pruriceptors drive pruritogen-induced alloknesis through mechanosensitive Piezo2 channel.

Although touch and itch are coded by distinct neuronal populations, light touch also provokes itch in the presence of exogenous pruritogens, resulting in a phenomenon called alloknesis. However, the cellular […]

Learned nocebo effects on cutaneous sensations of pain and itch: A systematic review and meta-analysis of experimental behavioral studies on healthy humans.

In past decades, the field of nocebo research has focused on studying how sensory perception can be shaped by learning. Nocebo effects refer to aggravated sensory experiences or increased sensitivity […]

Nalbuphine attenuates morphine-induced scratching by inhibiting PKCβ-dependent microglial activation and p38 phosphorylation in male mice.

Morphine-induced scratching (MIS) is a common adverse effect associated with the use of morphine as analgesia after surgery. However, the treatment of MIS is less than satisfactory due to its […]

Biologic versus small molecule therapy for treating moderate to severe atopic dermatitis: clinical considerations.

FDA approval of dupilumab for moderate-to-severe AD shifted the paradigm from use of broad, systemic immunosuppressants to a safer, targeted treatment and led to the emergence of newer interleukin (IL)-4/IL-13 […]

Acid-sensing ion channel 3 is required for agmatine-induced histamine-independent itch in mice.

Itch is a common symptom of many skin and systemic diseases. Identifying novel endogenous itch mediators and the downstream signaling pathways involved will contribute to the development of new strategies […]

Molecular mechanisms of MrgprA3-independent activation of the transient receptor potential ion channels TRPA1 and TRPV1 by chloroquine.

Itch associates several pathologies and is a common drug-induced side effect. Chloroquine (CQ) was reported to induce itch by activating the Mas-related G protein-coupled receptor MrgprA3 and subsequently TRPA1. In […]
