Coding of itch versus pain has been heatedly debated for decades. However, the current coding theories (labeled line, intensity, and selectivity theory) cannot accommodate all experimental observations. Here we identified a subset of spinal interneurons, labeled by gastrin-releasing peptide (Grp), that receive direct synaptic input from both pain and itch primary sensory neurons. When activated...
We compared itch sensations and axon reflex flare induced by transcutaneous electrical (0.08-8 ms, 2-200 Hz) and chemical (histamine iontophoresis; 100 microC) stimulation. Stimuli were applied to non-lesional volar wrist skin in 20 healthy human subjects and 10 patients with atopic dermatitis. Intensity of evoked itch and pain sensations were rated on a numerical rating scale (NRS) of 0 (no se...
Itch is thought to represent the peculiar response to stimuli conveyed by somatosensory pathways shared with pain through the activation of specific neurons and receptors. It can occur in association with dermatological, systemic and neurological diseases, or be the side effect of certain drugs. However, some patients suffer from chronic idiopathic itch that is frequently ascribed to psychologi...
Lung cancer is the most feared of all cancers because of its heterogeneity and resistance to available treatments. Cancer stem cells (CSCs) are the cell population responsible for lung cancer chemoresistance and are a very good model for testing new targeted therapies. Clomipramine is an FDA-approved antidepressant drug, able to inhibit in vitro the E3 ubiquitin ligase Itch and potentiate the p...
The Hippo tumor suppressor pathway, originally defined in fruit flies, regulates cellular proliferation and survival and exerts profound effects on normal mammalian cell fate and tumorigenesis. The present understanding of Hippo pathway components and mechanisms remains incomplete in cancer. WW domain-containing proteins regulate diverse biological processes through interaction with proline-tyr...

Itch is the most common dermatological symptom and worsens with stress. The general belief of a person in their own ability to cope in stressful situations, known as self-efficacy, is relevant in the management of chronic diseases other than skin diseases. The aim of this study was to explore the association between perceived self-efficacy, itch and stress among late-stage adolescents. The stud...
Pruritus is a frequently encountered symptom following burns. Higher intensity of itching has been associated with depth of the wounds and specific body locations but these differences are not well understood. Our aim was to investigate the intensity of post burn pruritus in grafted and non-grafted burns across anatomic areas and to report on itch-inducing factors and applied treatments. The st...
Circular RNAs with exonic sequences represent a special form of non-coding RNAs, discovered by analyzing a handful of transcribed genes. It has been observed that circular RNAs function as microRNA sponges. In the present study, we investigated whether the expression of circular RNAs is altered during the development of esophageal squamous cell carcinoma (ESCC). Using a TaqMan-based reverse tra...
Noncoding RNAs (ncRNAs) are the dominant product of eukaryotic transcription. These products range from short microRNAs (miRNAs) to long intergenic noncoding RNAs (lincRNAs). Circular RNAs composed of exonic sequences represent an understudied form of ncRNA that was discovered more than 20 years ago. Using a TaqMan-based reverse transcriptase polymerase chain reaction assay, we analyzed the rel...
