Orientia tsutsugamushi, a causative agent of scrub typhus, is an obligate intracellular bacterium, which escapes from the endo/phagosome and replicates in the host cytoplasm. O. tsutsugamushi infection induces production of pro-inflammatory mediators including interleukin-1β (IL-1β), which is secreted mainly from macrophages upon cytosolic stimuli by(More)
Interleukin-12, a heterodimeric cytokine comprising p40 and p35 subunits, plays an essential role in the regulating the differentiation of Th cells, which establish and maximize the capabilities of the immune system. The aim of present study is to screen the effect of 21 ginsenosides from steamed ginseng-leaves and flowers on IL-12 production in bone(More)
This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss. When immortalized rat vibrissa dermal papilla cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased. In addition, the G. elliptica extract significantly(More)
This report describes the anti-inflammatory effects of MeOH extract from leaves of Carpinus tschonoskii (CE) on primary bone marrow-derived macrophage (BMDMs) and dendritic cells (BMDCs). Primary BMDMs and BMDCs were used for pro-inflammatory cytokine production and Western blot analysis. Human embryonic kidney cell line 293 T (HEK293 T) was used to access(More)
A series of N-substituted-1,2,3-triazole murrayafoline A derivatives were successfully synthesized using click azide-alkyne Huisgen cycloaddition reaction between 1-methoxy-3-methyl-9-(3-azido)-propyl-9H-carbazole and substituted alkynes. Their chemical structures were confirmed by (1)H, (13)C NMR and HR-ESI-MS spectral data. In addition, the interested(More)
