Antigen-presenting cells including dendritic cells (DCs) express mannan receptors (MR) on their surface, which can be exploited in cancer therapy by designing immune-stimulatory viruses coated with mannan-modified capsids that then bind to DCs and initiate a potent immune response. Although the

OBJECTIVE
To test the anti-cancer effect of mannan-modified targeted nanoliposome on mice.
METHODS
The 3beta[N-(N',N'-dimethylaminoethane) -carbamoyl] cholesterol (DC-chol) was synthesized by the chemical reaction of cholesteryl chloroformate and N, N-dimethylethylendiamine. The DC-chol was then
Coating of mannan on LPD particles containing HPV E7 peptide significantly enhances immunity against HPV-positive tumor.

OBJECTIVE
Previously, our laboratory has reported that liposome-protamine-DNA (LPD) nanoparticle is an effective delivery system for tumor-associated antigens. Mannan, which potentially targets antigen-presenting cells, was coated on LPD to further enhance its antitumor
Mannan-modified adenovirus encoding VEGFR-2 as a vaccine to induce anti-tumor immunity.

OBJECTIVE
Dendritic cell (DC) vaccines are a promising immunotherapeutic approach for treatment and prevention of cancer. While this methodology is widely accepted, it also has some limitations. Antigen-presenting cells including DCs express the mannan receptor (MR). The delivery of a
Branched mannans from the mushroom Cantharellus cibarius enhance the anticancer activity of natural killer cells against human cancers of lung and colon.

Several studies have shown that mushroom polysaccharides enhance the ability of natural killer (NK) cells to recognize cancer cells as foreign and thereby enhance the effectiveness of host immune defence mechanisms. Nevertheless, the use of NK cells in cancer treatment requires finding selective
Oxidized and reduced mannan mediated MUC1 DNA immunization induce effective anti-tumor responses.

DNA immunization is an attractive form of vaccination, which has shown promising results only in small animal models. There is a need to develop efficient gene delivery systems. We previously demonstrated that oxidized (OM) and reduced mannan (RM) complexed to ovalbumin DNA via poly-l-lysine (PLL),
Growth-inhibitory activity of the D-mannan of Saccharomyces cerevisiae X2180-1A-5 mutant strain against mouse-implanted sarcoma 180 and Ehrlich-carcinoma solid tumor.

The D-mannan of Saccharomyces cerevisiae X2180-1A-5 mutant strain, which possesses a main chain composed of alpha-(1 yields 6) linked D-mannopyranosyl residues and a small proportion of branches composed of alpha-(1 yields 2)- and alpha-(1 yields 3)-linked D-mannopyranosyl residues, showed strong

BACKGROUND
Mucin 1 (MUC1) is a high molecular weight glycoprotein overexpressed on adenocarcinoma cells and is a target for immunotherapy protocols. To date, clinical trials against MUC1 have included advanced cancer patients. Herein, we report a trial using early stage breast cancer patients and

Mannan (mannose)-binding protein (MBP) is a C-type serum lectin that plays a key role in innate immunity. MBP forms large multimers (200-600 kDa) and exhibits broad specificity for mannose, N-acetylglucosamine, and fucose. MBP exhibits high affinity for unique oligosaccharides that have been

BACKGROUND
It has been reported that the tumor suppressor gene, PTEN, which is inactivated in many malignant tumors, plays an important role in apoptosis, cell cycle arrest, cell migration, and cell spread. For cancer gene therapy, one of the most important problems is low gene transfection
