Guinea pigs were treated with a specific blocker, CaCCinh-A01 (10 μM), administered via inhalation. A significant reduction in cough reflex sensitivity and specific airway resistance was observed in animals treated with CaCCinh-A01, highlighting its potential to improve airway function. Despite a reduction in ciliary beating frequency (CBF), CaCCinh-A01 reduced airway mucus viscosity by decreasing the production of mucin-5AC (MUC5AC). The nonspecific reduction in the Th1/Th2 cytokine spectrum following CaCCinh-A01 treatment indicated the suppression of airway inflammation. Additionally, markers associated with airway remodeling were diminished, suggesting that CaCCinh-A01 may counteract structural changes in airway tissues. Therefore, inhibition appears to mitigate the pathological aspects of asthma, including airway hyperresponsiveness, inflammation, and remodeling.

We prepared brain slices from mice pretreated with TND1128 (0.1–10 mg/kg, intraperitoneally) and detected ΔΨ<sub>m</sub> level with JC-1, a fluorescence ΔΨ<sub>m</sub> indicator.

We evaluated the effect of TND1128 by using the inverse number of the ΔΨ<sub>m</sub> value as the ATP synthesis index (ASI).

Further, CD34-negative HAVICs are highly sensitive to calcification stimulations. Here, we aimed to pathophysiologically clarify the role of CD34 in HAVICs obtained from individual patients with severe CAVS. A DNA microarray between CD34-positive and CD34-negative HAVICs, separated by fluorescence-activated cell sorting, indicated that tenascin X (TNX) mRNA expression significantly decreased in CD34-negative cells. Furthermore, the inflammatory cytokines, tumor necrosis factor (TNF)-α and interleukin (IL)-1β significantly downregulated CD34 expression in HAVICs. TGF-β, a key cytokine of endothelial-mesenchymal transition, did not affect HAVIC calcification. CD34 overexpression strongly inhibited TNF-α- and IL-1β-induced calcification and maintained TNX mRNA expression. These results suggest one possibility that CD34 is an inhibitory regulator of valve calcification.
