A novel powder-form combination adjuvant system containing two immunostimulatory compounds was firstly developed and evaluated as a therapeutic intervention for cancer immunotherapy. With the help of hyaluronic acid (HA), water insoluble monophosphoryl lipid A (MPL), QS21 and imiquimod (R837), could
Marine environments are an enormous source of materials with biological interest, such as sulphated polysaccharides, which have relevant biological activities. In this study the potential of salt pan brine water as an easily accessible source of sulphated polysaccharides was evaluated. This water
The extracts having diverse immunostimulating activities were obtained as a water-phase fraction from four bacterial species representing the 4 genera (Mycobacterium, Nocardia, Gordona, and Rhodococcus) of Mycobacteriaceae by the phenol-water method, which is commonly used for extraction of
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 water-soluble polysaccharide LMP-1 was isolated and purified by ion-exchange chromatography from maca (Lepidium meyenii Walp.). LMP-1 has a molecular weight of 1.01 × 104 Da, and is composed of glucose and arabinose with a molar ratio of 7.03:1.08. Methylation and the 1D and 2D NMR spectroscopy of
QS-21 is a purified immunological adjuvant derived from a natural source, the bark of the tree Quillaja saponaria. It is a water soluble triterpene glycoside with amphiphilic character that can be mixed with a soluble antigen in a fully soluble vaccine formulation or combined with emulsion or
Polysaccharide with the enhanced immunostimulatory activities including intestinal immune system modulation was fractionated from Korean red ginseng (KRG) and its characteristics were investigated in the present experiment. When the water extracts were digested with α-amylase and amyloglucosidase
Water-soluble polysaccharides were obtained from Cordyceps militaris (C. militaris) (CMP) by subcritical water extraction (SWE). Two polysaccharides fractions, CMP-W1 and CMP-S1, were isolated from CMP using DEAE-52 cellulose and Sephadex G-150 column chromatography. The structural characteristics
A number of immunostimulant effects of herbal medicines have been reported; however, the underlying mechanisms of their immunostimulatory effects have not been elucidated in detail. Our previous study showed that sugar-based nanoparticles derived from cell walls acted as the immunostimulatory
The immunostimulatory effects of the representative dental resin monomer 2-hydroxyethyl methacrylate (HEMA), a HEMA derivative that does not contain a double bond (2-hydroxyethyl isobutyrate, HEIB), and polymerized water-soluble oligomers of HEMA (PHEMA) were investigated. It is known that
Polyacetylenes in the bark of Dendropanax morbifera trees have been reported to promote immune cell proliferation and to strengthen the innate immune system. The immunomodulatory potential of D. morbifera branch water extract (DBW) was evaluated by determining its effect on cell
A new polysaccharide had been successfully isolated from maitake mushroom (Grifola Frondosa)-GFP. HPLC and Monosaccharide analysis showed that the average molecular weight of GFP was 155kDa and it was mainly composed of rhamnose, xylose, mannose, glucose, molar ratio of 1.00: 1.04: 1.11: 6.21. FTIR,
In the present study, we obtained polysaccharides from Sagittaria sagittifolia L. (SSP) with subcritical water extraction (SWE). Two water-soluble polysaccharides (SSP-W1 and SSP-S1) from the acquired SSP were isolated with DEAE-52 and Sephadex G-100. Besides, the structural characteristics and
A synthetic oligonucleotide containing a previously identified adjuvant active CpG DNA sequence was evaluated for its ability to augment antibody and CTL responses to p55 gag from HIV-1 in mice. Surprisingly, the CpG oligonucleotide, although, it had previously been described as the most potent
In this study, water extracts of the red seaweed Sarcodia suiae were obtained using solid-liquid extraction (SLE) or pressurized liquid extraction (PLE) methods. The extracts were used to investigate immunostimulatory activity by measuring the phagocytic activity of Nile tilapia (Oreochromis
