stephania wightii/hypersensitivity

Cepharanthine, a biscouclaurine alkaloid of Stephania cepharantha, has been used for various clinical purposes. Cepharanthine was known to inhibit histamine release from mast cells obtained from sensitized animals. In vitro studies suggested that the mechanism of action of cepharanthine may be

Inflammatory cytokines and human immunodeficiency virus type 1 (HIV-1) gp120 are considered to play an important role in the pathogenesis of HIV-1-associated CNS disorders. These substances are produced predominantly by HIV-1-infected or activated macrophages and microglia in the brain and induce

Dendritic cells (DCs) are specialized antigen presenting cells that connect innate and adaptive immunity. DCs are considered as a major target for controlling excessive immune responses. In this study, the effect of cepharanthine (CEP), a biscoclaurine alkaloid isolated from Stephania cepharantha

BACKGROUND Cepharanthine (CEP) is a biscoclaurine amphipathic alkaloid isolated from the plant Stephania cepharantha Hayata. Although the effects of CEP on several types of cells have been investigated, those on dendritic cells (DCs) are poorly understood. OBJECTIVE To investigate the effect of CEP

We have already demonstrated that human head and neck cancer cells have significantly enhanced levels of transcription factor nuclear factor (NF)-kappaB activity compared to their normal counterparts, suggesting that NF-kappaB plays an important role in the development of head and neck cancer.
