Induction of Antitumor Immunity by Transduction of CD40 Ligand Gene
D2001 Nature Publishing Group 0929-1903/01/$17.00/+0 www.nature.com/cgt Induction of antitumor immunity by transduction of CD40 ligand gene and interferon- gene into lung cancer Masahiro Noguchi,1 Kazuyoshi Imaizumi,1 Tsutomu Kawabe,1 Hisashi Wakayama,1 Yoshitsugu Horio,1 Yoshitaka Sekido,2 Toru Hara,1 Naozumi Hashimoto,1 Masahide Takahashi,3 Kaoru Shimokata,2 and Yoshinori Hasegawa1 1First Department of Internal Medicine, Nagoya University School of Medicine, Nagoya, Japan; Departments of 2Clinical Preventive Medicine and 3Pathology, Nagoya University School of Medicine, Nagoya, Japan. CD40±CD40 ligand (CD40L) interaction is an important costimulatory signaling pathway in the crosstalk between T cells and antigen-presenting cells. This receptor±ligand system is known to be essential in eliciting strong cellular immunity. Here we demonstrate that murine lung cancer cells (3LLSA) transduced with the CD40L gene (3LLSA-CD40L) were rejected in syngeneic C57BL/6 mice, but grew in CD40-deficient mice to the same extent as control tumor cells. Immunohistochemical study showed that inflammatory cells, including CD4+, CD8+ T cells and NK cells, infiltrated into the inoculated 3LLSA-CD40L tumor tissue. Inoculation of 3LLSA-CD40L cells into mice resulted in the induction of 3LLSA-specific cytotoxic T-cell immunity, and the growth of parental 3LLSA tumors was inhibited when 3LLSA cells were inoculated into C57BL/6 mice mixed with 3LLSA-CD40L cells or when they were rechallenged 4 weeks after 3LLSA-CD40L cells were rejected. Furthermore, co-inoculation of interferon (IFN)- ± transduced cells (3LLSA-IFN ) with 3LLSA-CD40L cells enhanced the antitumor immunity efficiently in vivo. These results indicate that the in vivo priming with CD40L- and IFN- gene±transduced lung cancer cells is a promising strategy for inducing antitumor immunity in the treatment of lung cancer. -
BD Pharmingen™ FITC Mouse Anti-Rat CD134
BD Pharmingen™ Technical Data Sheet FITC Mouse Anti-Rat CD134 Product Information Material Number: 554848 Alternate Name: OX-40 Antigen Size: 0.5 mg Concentration: 0.5 mg/ml Clone: OX-40 Immunogen: Activated rat lymph node cells Isotype: Mouse (BALB/c) IgG2b, κ Reactivity: QC Testing: Rat Storage Buffer: Aqueous buffered solution containing ≤0.09% sodium azide. Description The OX-40 antibody reacts with the 50-kDa OX-40 Antigen (CD134), also known as OX-40 Receptor, on CD4+ T lymphocytes activated in vitro and in vivo. The antigen is a member of the NGFR/TNFR superfamily, which includes low-affinity nerve growth factor receptor, TNF receptors, the Fas antigen, CD137 (4-1BB), CD27, CD30, and CD40. CD134 supplies costimulatory signals for T-cell proliferation and effector functions. While OX-40 mAb is not mitogenic, it does augment some in vitro T-cell responses. It is also reported to block binding of OX-40 Ligand to OX-40 Antigen. Preparation and Storage The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed. Store undiluted at 4° C and protected from prolonged exposure to light. Do not freeze. Application Notes Application Flow cytometry Routinely Tested Suggested Companion Products Catalog Number Name Size Clone 559532 FITC Mouse IgG2b, κ Isotype Control 0.25 mg MPC-11 Product Notices 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results. 2. Please refer to www.bdbiosciences.com/pharmingen/protocols for technical protocols. -

We previously reported that OK-432 treatment can induce the production of high levels of IFN-γ from peripheral blood mononuclear cells (PBMCs). Moreover, the IFN-γ production from PBMCs by OK-432 is impaired by conditioned media (CM) from oral cancer cells. To determine the inhibitory mechanism of IFN-γ production by CM, the genes involved in IFN-γ production was Citation: Ohe, G.; Kudo, Y.; Kamada, retrieved by cDNA microarray analysis. We found that CD40 played a key role in IFN-γ production K.; Mouri, Y.; Takamaru, N.; Kudoh, via IL-12 production. -

To this end, we evaluated whether addition of IL-21 would further enhance this TLR-driven stimulation approach; which it did not. More importantly, as most antigen-specific B cell responses are T cell-driven, we sought to devise a polyclonal B cell stimulation protocol that closely mimics T cell help. Herein, we report that the combination of agonistic anti-CD40, IL-4 and IL-21 affords polyclonal B cell stimulation that was comparable to R848 and IL-2 for detection of influenza-specific memory B cells. An additional advantage of anti-CD40, IL-4 and IL-21 stimulation is the selective activation of IgM+ memory B cells, as well as the elicitation of IgE+ ASC, which the former fails to do. Thereby, we introduce a protocol that mimics physiological B cell activation through helper T cells, including induction of all Ig classes, for immune monitoring of antigen-specific B cell memory. -
