Background: The aim of study is to investigate the role of transient receptor potential cation channel subfamily V member 1 (TRPV1) on xerostomia-induced inflammatory response in vivo.
Methods: Parotid, submandibular, and lingual gland were removed for xerostomia induction. The expression of inflammatory cytokines, TRPV1, NFkB, and MAPK in xerostomia was evaluated and compared in both TRPV1 wild and knockout mice.
Results: The level of interleukin-6 (IL-6) and IL-17, neutrophil/CD4 T-cell infiltration, phosphorylation of extracellular signal-regulated kinase (ERK) and c-Jun N terminal kinase, TRPV1, and the localization of NFkB were elevated in xerostomia-induced TRPV1 wild-type mice. In contrast, inflammatory cytokines and MAPK were decreased in xerostomia-induced TRPV1 knockout mice. TRPV1 antagonist treatment also reduced tongue ulceration, neutrophil/CD4 T-cell expression, IL-6, and IL-17 in TRPV1 wild-type mice.
Conclusion: TRPV1 had a crucial role in modulating inflammation in xerostomia and targeting TRPV1 might be a promising therapeutic strategy for xerostomia.

Capsaicin, a polyphenol, is known to regulate energy expenditure and thermogenesis in adipocytes and muscles. However, its role in modulating uncoupling proteins (UCPs) and adenosine triphosphate (ATP)-dependent thermogenesis in muscles remains unclear. This study investigated the mechanisms underlying the role of capsaicin in modulating the UCP- and ATP-dependent thermogenesis in C2C12 myoblasts, as well as the gastrocnemius (GM) and soleus muscles (SM) of mice.

Article Synopsis
- Oral mucosal wounds are susceptible to inflammation and complications due to exposure to microorganisms, which can hinder daily activities and diminish quality of life.
- A novel therapeutic nanoplatform, DATS@Arg-EA-SA, has been developed to target these wounds by combining guanidinated dendritic peptides with diallyl trisulfide (DATS), providing both antimicrobial and anti-inflammatory effects.
- This nanoplatform effectively eliminates various bacteria, including drug-resistant strains like MRSA, and enhances healing by promoting the transition of inflammatory cells and alleviating pain, making it a promising solution for oral wound treatment.

Ion channels are generally allosteric proteins, involving specialized stimulus sensor domains conformationally linked to the gate to drive channel opening. Temperature receptors are a group of ion channels from the transient receptor potential family. They exhibit an unprecedentedly strong temperature dependence and are responsible for temperature sensing in mammals.

Severe trauma frequently leads to nerve damage. Peripheral nerves possess a degree of regenerative ability, and actively promoting their recovery can help restore the sensory and functional capacities of tissues. The neuropeptide calcitonin gene-related peptide (CGRP) is believed to regulate the repair of injured peripheral nerves, with neuronal transient receptor potential vanilloid type 1 (TRPV1) potentially serving as a crucial upstream factor.

Objective: To evaluate the therapeutic effects of Kuanxiong Aerosol (KXA) on ischemic stroke with reperfusion and elucidate the underlying pharmacological mechanisms.
Methods: In vivo pharmacological effects on ischemic stroke with reperfusion was evaluated using the transient middle cerebral artery occlusion (t-MCAO) mice model. To evaluate short-term outcome, 30 mice were randomly divided into vehicle group (n=15) and KXA group (n=15).
