Inhibition of antitumor immunity by B cells.
In the August issue of Cancer Research , Inoue et al. reported a mechanism by which B cells inhibit the immune response against tumors. Their results support a model whereby B cell stimulation via CD40 leads to diminished CD8 and natural killer cell–mediated IFN-g secretion and thereby attenuates antitumor immunity (1). Their results are in line with findings previously published in 2005 in our...
متن کاملTransfer of in vitro-expanded naïve T cells after lymphodepletion enhances antitumor immunity through the induction of polyclonal antitumor effector T cells
The adoptive transfer of effector T cells combined with lymphodepletion has demonstrated promising antitumor effects in mice and humans, although the availability of tumor-specific T cells is limited. We and others have also demonstrated that the transfer of polyclonal naïve T cells induces tumor-specific effector T cells and enhances antitumor immunity after lymphodepletion. Because tumors hav...
متن کاملGold nanoparticle-induced sonosensitization enhances the antitumor activity of ultrasound in colon tumor-bearing mice
Introduction: Light-driven cancer therapy strategies (e.g. photodynamic therapy and photothermal therapy) have undergone remarkable progress in recent years, but they still suffer from a serious drawback of limited penetration depth of light in tissue. As a non-invasive and non- ionizing radiation, ultrasound can be focused remotely, transferring acoustic energy deep in the bo...
متن کاملInhibitory effects of B cells on antitumor immunity.
B-cell functions in antitumor immunity are not well understood. In this study, we evaluated the role of B cells in the development of antitumor immunity using Friend murine leukemia virus gag-expressing mouse EL-4 (EL-4 gag), D5 mouse melanoma, or MCA304 mouse sarcoma cells. To screen tumors for susceptibility to B-cell-deficient immune environments, spleen cells from naive C57BL/6 [wild-type (...
متن کاملStat3 inhibition augments the immunogenicity of B-cell lymphoma cells, leading to effective antitumor immunity.
Mantle cell lymphoma (MCL) is an aggressive and incurable subtype of B-cell non-Hodgkin lymphomas. Although patients often respond initially to first-line treatment with chemotherapy plus monoclonal antibodies, relapse and decreased response to further lines of treatment eventually occurs. Harnessing the immune system to elicit its exquisite specificity and long-lasting protection might provide...
