4-1BB Signaling Beyond T Cells
Cellular & Molecular Immunology (2011) 8, 281–284 ß 2011 CSI and USTC. All rights reserved 1672-7681/11 $32.00 www.nature.com/cmi MINI REVIEW 4-1BB signaling beyond T cells Dass S Vinay1 and Byoung S Kwon1,2 Originally discovered as a T cell-activating molecule, 4-1BB (CD137) is now also recognized as an activator of non-T cells, thus imparting a new dimension to its potential in vivo effects. 4-1BB expression is seen on a variety of non-T cells including activated dendritic cells (DCs), monocytes, neutrophils, B cells and natural killer (NK) cells, and promotes their individual effector functions. The T cell- and non-T cell-activating ability of 4-1BB may be the basis of its powerful anti-cancer, anti-autoimmune and anti-viral effects. Here we discuss the consequence and importance of 4-1BB signaling in non-T cells. We consider its effects on immune regulation, and the distinct and/or overlapping pathways involved in these responses, as well as possible therapeutic applications.

Welcome to More Choice CD Marker Handbook For more information, please visit: Human bdbiosciences.com/eu/go/humancdmarkers Mouse bdbiosciences.com/eu/go/mousecdmarkers Human and Mouse CD Marker Handbook Human and Mouse CD Marker Key Markers - Human Key Markers - Mouse CD3 CD3 CD (cluster of differentiation) molecules are cell surface markers T Cell CD4 CD4 useful for the identification and characterization of leukocytes. The CD CD8 CD8 nomenclature was developed and is maintained through the HLDA (Human Leukocyte Differentiation Antigens) workshop started in 1982. CD45R/B220 CD19 CD19 The goal is to provide standardization of monoclonal antibodies to B Cell CD20 CD22 (B cell activation marker) human antigens across laboratories. To characterize or “workshop” the antibodies, multiple laboratories carry out blind analyses of antibodies. These results independently validate antibody specificity. CD11c CD11c Dendritic Cell CD123 CD123 While the CD nomenclature has been developed for use with human antigens, it is applied to corresponding mouse antigens as well as antigens from other species. However, the mouse and other species NK Cell CD56 CD335 (NKp46) antibodies are not tested by HLDA. Human CD markers were reviewed by the HLDA. New CD markers Stem Cell/ CD34 CD34 were established at the HLDA9 meeting held in Barcelona in 2010.

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. -

TRAIL and Cardiovascular Disease—A Risk Factor Or Risk Marker: a Systematic Review

Data from animal studies indicate that TRAIL may possibly contribute to the pathophysiology of cardiomyopathy, atherosclerosis, ischemic stroke and abdomi- nal aortic aneurysm. It has been also suggested that TRAIL might be useful in cardiovascular risk stratification. This systematic review aimed to evaluate whether TRAIL is a risk factor or risk marker in cardiovascular diseases (CVDs) focusing on major adverse cardiovascular events. Two databases (PubMed and Cochrane Library) were searched until December 2020 without a year limit in accor- dance to the PRISMA guidelines. A total of 63 eligible original studies were identified and included in our systematic review. Studies suggest an important role of TRAIL in disorders such as heart failure, myocardial infarction, atrial fibrillation, ischemic stroke, peripheral artery disease, and pul- monary and gestational hypertension. Most evidence associates reduced TRAIL levels and increased TRAIL-R2 concentration with all-cause mortality in patients with CVDs. It is, however, unclear Citation: Kakareko, K.; whether low TRAIL levels should be considered as a risk factor rather than a risk marker of CVDs. -

Herein, we present single-cell tran- scriptome profiling of metastatic lung adenocarcinoma, the most prevalent histological lung cancer type diagnosed at stage IV in over 40% of all cases. From 208,506 cells populating the normal tissues or early to metastatic stage cancer in 44 patients, we identify a cancer cell subtype deviating from the normal differentiation trajectory and dominating the metastatic stage. In all stages, the stromal and immune cell dynamics reveal ontological and functional changes that create a pro-tumoral and immunosuppressive microenvironment. Normal resident myeloid cell populations are gradually replaced with monocyte-derived macrophages and dendritic cells, along with T-cell exhaustion. This extensive single-cell analysis enhances our understanding of molecular and cellular dynamics in metastatic lung cancer and reveals potential diagnostic and therapeutic targets in cancer-microenvironment interactions. 1 Samsung Genome Institute, Samsung Medical Center, Seoul 06351, Korea. -

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.
