brassica gravinae/免疫増強薬

Genomic DNA sequences (bacteria, insect, nematodes and molluscs) or synthetic oligodeoxynucleotides (ODN) containing unmethylated CpG motifs (CpG-DNA/ODN) are regarded as promising candidates for new medical adjuvants for their ability to stimulate the mammalian immune system and enhance immune

The water-soluble fraction of kale (Brassica oleracea L. var. acephala DC.) had immunoglobulin (Ig) production stimulating activity in human hybridoma HB4C5 cells and human peripheral blood lymphocytes. The biochemical and physical properties of the main active substance in kale were found to be a

A heterodimeric 13.8 kDa napin-like polypeptide has previously been isolated from Chinese cabbage (Brassica parachinensis) seeds with a procedure involving ion exchange chromatography on DEAE-cellulose, affinity chromatography on Affi-gel blue gel, FPLC-ion exchange chromatography on Mono S and

Two neutral polysaccharides (BRNP-1, 6.9 kDa; BRNP-2, 4.8 kDa) were purified from the common edible plant Brassica rapa L. via the combined techniques of ion-exchange chromatography and high-performance gel permeation chromatography. Monosaccharide composition analysis showed that BRNP-1 and BRNP-2

This study was done to investigate whether white cabbage contained polysaccharides with immunostimulatory activity using the complement-fixing test as an indicator. The main polysaccharide isolated was of pectin nature. Methanolysis and (13)C-NMR showed that the polymers consisted of highly

Polysaccharides are a type of natural macromolecule widely existing in nature, and its pharmacological activity has attracted wide research attention. In this study, Brassica rapa L. polysaccharides were taken as the research object, and a preliminary study of the immune activity and mechanism of

Certain food components possess immunomodulatory effects. The aim of this study was to elucidate the mechanism of the immunostimulatory activity of Brassica rapa L. We demonstrated an enhancement of natural killer (NK) activity and interferon (IFN)-γ production in mice that were orally administered
