House dust mite (HDM) is a primary allergen in allergic rhinitis (AR) and asthma. Neutrophil apoptosis is associated with allergic diseases and innate immunity to infection. The present study examined how HDM affects constitutive neutrophil apoptosis in normal and AR subjects. Total IgE increased in AR subjects when compared to normal subjects, and patients(More)
Parkinson’s disease (PD) is a neurodegenerative disorder characterized by loss of dopaminergic neurons in the substantia nigra pars compacta. In this study, we investigated the effects of a novel herb formula, Hepad, on PD. Dose-dependent treatment with 1-methyl-4-phenylpyridinium (MPP+) decreased the viability of SH-SY5Y cells, and Hepad inhibited the(More)
House dust mite (HDM) is an essential allergen in allergic diseases such as allergic rhinitis and asthma. The pathogenic mechanism of allergy is associated with cytokine release of lymphocytes and constitutive apoptosis of neutrophils. In this study, we examined whether HDM induces cytokine release of lymphocytes and whether the secretion of cytokines is(More)
House dust mites (HDMs) induce allergic diseases such as asthma. Neutrophil apoptosis is an important process of innate immunity, and its dysregulation is associated with asthma. In this study, we examined the effects of HDM on constitutive apoptosis of normal and asthmatic neutrophils. Extract of Dermatophagoides pteronissinus (DP) inhibited neutrophil(More)
Arazyme is a metalloprotease released by Aranicola proteolyticus that was shown to inhibit cytokine release in HaCaT and endothelial cells. However, the regulatory effects of arazyme in atopic dermatitis remain to be fully understood. In the present study, the anti‑inflammatory effects of arazyme in BALB/c and Nc/Nga mice induced with(More)
Although extract of Dermatophagoides farinae (DF) alone had no effect on neutrophil apoptosis, it inhibited neutrophil apoptosis in neutrophils cocultured with lymphocytes in both normal and allergic subjects. DF showed a stronger inhibition on the apoptosis of allergic neutrophils cocultured with allergic lymphocytes than that of normal neutrophils(More)
Histone deacetylase (HDAC) inhibitors have been recognized as promising approaches to the treatment of various human diseases including cancer, inflammation, neurodegenerative diseases, and metabolic disorders. Several pan-HDAC inhibitors are currently approved only as anticancer drugs. Interestingly, SAHA (vorinostat), one of clinically available pan-HDAC(More)
House dust mite is a major allergen in allergic diseases such as asthma. In this study, we investigated the effects of house dust mite on constitutive eosinophil apoptosis in normal and asthmatic subjects. We classified asthmatic subjects into those with atopic and non-atopic asthma depending on the presence of DP-specific IgE or/and DF-specific IgE in(More)
