Chemokine receptor CX3CR1(+) dendritic cells (DCs) have been suggested to sample intestinal antigens by extending transepithelial dendrites into the gut lumen. Other studies identified CD103(+) DCs in the mucosa, which, through their ability to synthesize retinoic acid (RA), appear to be capable of generating typical signatures of intestinal adaptive immune(More)
BACKGROUND Accurate predictors of survival for patients with advanced gastric cancer treated with neoadjuvant chemotherapy are currently lacking. In this study, we aimed to evaluate the prognostic significance of the neutrophil-lymphocyte ratio (NLR) in patients with stage III-IV gastric cancer who received neoadjuvant chemotherapy. METHODS We enrolled 46(More)
When telomeres are shortened to a critical length, they will initiate chromosomal instability (CIN) and may finally cause tumorigenesis. The purpose of the present study was to evaluate the shortened telomere as a potential biomarker for tumorigenesis in gastric carcinoma. The telomeres in matched cancer and adjacent noncancer mucosa samples from 86 gastric(More)
Deficiency of transplant recipients for the chemokine receptor CCR7 was originally described to slightly increase the survival time of vascularized solid organ grafts, probably due to a reduced priming of alloreactive T cells. Using a model of allotolerance induction by donor-specific splenocyte transfusion (DST) in combination with anti-CD40L mAb-mediated(More)
Interleukin-17 (IL-17) is prevalent in tumor tissue and suppresses effective anti-tumor immune responses. However, the source of the increased tumor-infiltrating IL-17 and its contribution to tumor progression in human gastric cancer remain poorly understood. In this study, we enrolled 112 gastric cancer patients, immunofluorescence was used to evaluate the(More)
Unlike the ∼1% of γδ TCR-positive T cells being regularly present in blood and secondary lymphoid organs (peripheral γδ T cells), ∼50-60% of small intestinal intraepithelial lymphocytes (iIELs) in the mouse express the γδ TCR (γδ iIELs). In this study, we investigated the overlap and exchange of γδ iIELs and γδ T cells found in peripheral secondary lymphoid(More)
Immunosuppressive lymphocytes, such as regulatory T cells (Tregs) and plasmacytoid dendritic cells (pDCs), play crucial roles in tumor escape. To investigate the roles of Tregs and pDCs in papillary thyroid cancer (PTC) plus multinodular non-toxic goiter (MNG), thyroid tissue and blood samples from 30 patients with PTC plus MNG and 30 MNG alone were(More)
Collagen VI is significant in the progression of numerous types of cancer. Type VI collagen consists of three α-chains and collagen VI α3 (COL6A3) encodes the α3 chain. The overexpression of COL6A3 has been demonstrated to correlate with high-grade ovarian cancer and contributes to cisplatin resistance; however, its role in human gastric cancer (GC) remains(More)
BACKGROUND The purpose of this study was to investigate in vivo the arterial wall temperature after coronary stent implantation in pigs. METHODS We performed cardiac catheterization in 20 pigs with normal coronary arteries. Arterial wall temperature was studied with a thermography system that uses a 4-thermistor sensor tip. A segment was selected in the(More)
BACKGROUND The development of microsurgical techniques has facilitated the establishment of fully vascularized cardiac transplantation models in small mammals. Anastomotic stenosis and bleeding continue to hamper procedures and limit long-term graft survival. In this study we assess a novel technique to improve outcome after cardiac transplantation in mice.(More)
