NMR characterization of the polysaccharidic fraction from Lentinula edodes grown on olive mill waste waters

A high-field NMR study of the polysaccharidic fraction extracted from Lentinula edodes mycelium grown on olive mill waste waters is reported. Diffusion-ordered NMR spectroscopy (DOSY) was applied to the polysaccharidic fraction. The results showed the presence of two polysaccharides of different sizes, whose structures were revealed using one- and two-dimensional NMR techniques. These two polysaccharides were identified as xylan and lentinan.     

Curative effects of combination therapy with lentinan and interleukin-2 against established murine tumors,and the role of CD8-positive T cells

The antitumor activity of a combination of an antitumor polysaccharide, lentinan (a 1–3 glucan with 1–6 branches), and interleukin-2 (IL-2) was evaluated against established MBL-2 lymphoma and S908.D2 sarcoma at i.d. sites. Treatment of the MBL-2-tumor-bearing BDF1 mice with lentinan and IL-2 induced complete regression of tumor in 87.5% of mice treated. In contrast, treatments using either lentinan or IL-2 alone failed to induce complete regression of tumor, although temporal growth inhibition of tumor was observed about in half of the mice treated. Improvements of antitumor effects by the combination of lentinan and IL-2 were also observed in the MBL-2/B6 and S908.D2/B10.D2 systems. Expression of the antitumor effects of lentinan/IL-2 treatments required the intact T cell compartment, because the effects were not observed when nude mice were used. In the MBL-2/B6 system, the antitumor action of lentinan/IL-2 treatment was abolished in mice treated with antibody to CD8 antigen, whereas antibodies to CD4 or NK1.1 were ineffective. Furthermore, augmented tumor-specific cytotoxic T lymphocyte (CTL) activity was observed in regional lymph node cells of the mice after lentinan and IL-2 administration. These data indicate that the antitumor effects of lentinan/IL-2 are mediated by CD8⁺ CTL but not by CD4⁺ T cells or NK1.1⁺ NK/LAK cells, and suggest that this combined therapy may be effective against even established tumors that are resistant to IL-2 therapy.Abbreviations B6 C57BL/6 - BDF1 C57BL/6 × DBA/2 F1 - Lyt2 murine CD8, Lyt2.1. allele of murine CD8 - Lyt2.2 allele of murine CD8 - Lyt3 murine CD8 - L3T4 murine CD4     

Effect of lentinan on macrophage cytotoxicity against metastatic tumor cells

We studied the effect of lentinan, a fungal polysaccharide immunomodulator, on mouse peritoneal macrophages. The i.p. treatment of mice with 10 mg/kg lentinan affected the number, plastic-adherence, and endogen peroxidase activity of peritoneal cells. The cytotoxicity of lentinan-stimulated peritoneal macrophages was determined against several murine and human metastatic tumor targets: Lewis lung carcinoma (LLT) and two human melanomas, and was found to be significantly higher than that of the macrophages from control animals. However, the highly metastatic variant of LLT (LLT-HH) was resistant to the cytolytic effect of resident and lentinan-activated macrophages as well, indicating that the stimulation for cytotoxicity depends not only on the functional activity of the effector but also on the sensitivity of the target.
