Pretreatment with the ultrapotent capsaicin analog resiniferatoxin (RTX) has been applied as a selective pharmacological tool in inflammation and pain studies to desensitize transient receptor potential vanilloid 1 (TRPV1) receptor-expressing sensory nerve endings. The discovery of TRPV1 receptor on non-neural cells challenges systemic RTX desensitization(More)
Transient Receptor Potential Ankyrin 1 (TRPA1) channels are localized on sensory nerves and several non-neural cells, but data on their functional significance are contradictory. We analysed the presence and alterations of TRPA1 in comparison with TRP Vanilloid 1 (TRPV1) at mRNA and protein levels in human and mouse intact and inflamed colons. The role of(More)
The function of the neurokinin 1 (NK1) receptor was investigated in the DSS-induced mouse colitis model using NK1 receptor-deficient mice and the selective antagonist netupitant. Colitis was induced by oral administration of 20 mg/ml DSS solution for 7 days in C57BL/6 and Tacr1 KO animals (n = 5–7). During the induction, one-half of the C57BL/6 and Tacr1 KO(More)
OBJECTIVES Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa. Its etiology is still unclear. Neurogenic components might contribute to the inflammatory process. The oral mucosa is richly innervated by sensory fibers. Mediators secreted by inflammatory cells activate sensory nerves via transient receptor potential vanilloid(More)
