Chemical investigation of the ethanol extract of soft coral Sinularia sp. collected from the South China Sea led to the isolation of three new polyoxygenated sterols, (3S,23R,24S)-ergost-5-ene-3β,23α,25-triol (1), (24S)-ergostane-6-acetate-3β,5α,6β,25-tetraol (2), (24S)-ergostane-6-acetate-3β,6β,12β,25-tetraol (3) together with three known ones (4-6). The structures, including relative configur...
Our previously conducted pharmacological investigations led us to discovery of the strong local anesthetic activity of the compound KP-23RS. The following studies revealed that its Rand S-diasteroisomers had different activity in the local anesthetic, anti-aggregating, anti-arrhythmic and spasmolytic tests. Also the influence of KP-23RS and its diastereoisomers on the cyclic adenosine monophosp...
Th17 cells play reciprocal roles in different forms and at different stages of cancer. We report that the presence of Th17 cells in ovarian cancer ascites correlates with local expression of nitric oxide synthase-2 (NOS2). Furthermore, the development of RORgt+IL-23R+IL-17+ Th17 cells from human naive-, memoryor tumorinfiltrating CD4+ T cells critically depends on NO and endogenous NOS2 induced...
Innate lymphoid cells (ILCs) contribute to host defence and tissue repair but can induce immunopathology. Recent work has revealed tissue-specific roles for ILCs; however, the question of how a small population has large effects on immune homeostasis remains unclear. We identify two mechanisms that ILC3s utilise to exert their effects within intestinal tissue. ILC-driven colitis depends on prod...
We recently reported the genetic cause of autosomal dominant chronic mucocutaneous candidiasis (AD-CMC) as a mutation in the STAT1 gene. In the present study we show that STAT1 Arg274Trp mutations in the coiled-coil (CC) domain is the genetic cause of AD-CMC in three families of patients. Cloning and transfection experiments demonstrate that mutated STAT1 inhibits IL12R/IL-23R signaling, with h...
The biliary bile acid composition of 10 anseriform and three flamingo species was determined using a variety of chromatographic techniques. Some bile samples contained an unusual 23-hydroxylated derivative of chenodeoxycholic acid, (23R)-3a,7a,23_trihydroxy-5P-cholan-24-oic acid (P-phocacholic acid). The proportion of this unusual bile acid correlated highly with the order of evolutionary appea...
