Lentinan, an antitumor polysaccharide used clinically in Japan, requires the
intact T cell compartment to manifest its antitumor effects. The aim of the
current study was to clarify the mechanisms playing crucial roles in the T cell
requirement in the expression of antitumor effects of lentinan. Lentinan
treatment of BDF1 mice transplanted intradermally with FBL-3 induced complete
tumor regression and a marked increase in survival time. The antitumor action of
lentinan was abolished in mice treated simultaneously with antibodies to CD4 and
CD8 antigens, whereas antibody to CD4, CD8 or NK1.1 alone was ineffective. The
natural killer, cytotoxic T lymphocyte, and helper T cell activities were already
augmented in this FBL-3/BDF1 system and thus further augmentation of these
activities by lentinan was not observed. These activities did not correlate with
the antitumor activity of lentinan, as was confirmed in lymphocyte subset
depletion experiments. On the contrary, the delayed-type hypersensitivity (DTH)
response against tumor-associated antigens was triggered by lentinan and was
abrogated only in mice treated simultaneously with antibodies to CD4 and CD8
antigens. Furthermore, a non-cytolytic tumor-associated antigen-specific CD4+ T
cell clone able to induce the DTH response in concert with lentinan reconstituted
the antitumor effects in B6 nude mice when administered with lentinan. These
results suggest that, in addition to the augmentation of immune effector cell
activity against tumors, infiltration of these cells into the tumor burden
initiated by the DTH responses at tumor sites may be involved in eradication of
tumors by lentinan.
