Luteolin reduces fluid hypersecretion by inhibiting TMEM16A in interleukin-4 treated Calu-3 airway epithelial cells.

Rhinorrhea in allergic rhinitis (AR) is characterized by the secretion of electrolytes in the nasal discharge. The secretion of Cl and HCO is mainly regulated by cystic fibrosis transmembrane conductance regulator (CFTR) or via the calciumactivated Cl channel anoctamin-1 (ANO1) in nasal gland serous cells. Interleukin-4 (IL-4), which is crucial in the development of allergic inflammation, increases the expression and activity of ANO1 by stimulating histamine receptors.

Activation of transient receptor potential vanilloid 3 by the methanolic extract of fruit and its chemical constituent γ-schisandrin.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel with modest permeability to calcium ions. It is involved in intracellular calcium signaling and is therefore important in processes such as thermal sensation, skin barrier formation, and wound healing. TRPV3 was initially proposed as a warm temperature sensor.

Differential modulation of TWIK-related K channel (TREK) and TWIK-related acid-sensitive K channel 2 (TASK2) activity by pyrazole compounds.

Pyrazole derivatives were originally suggested as selective blockers of the transient receptor potential cation 3 (TRPC3) and channel. In particular, pyr3 and 10 selectively inhibit TRPC3, whereas pyr2 (BTP2) and 6 inhibit ORAI1. However, their effects on background K channel activity have not been elucidated.
