Decidual lymphocytes may mediate fetal trophoblast recognition and regulate maternal immune reaction and play an essential role in the maintenance of normal pregnancy. The aim of this study was to compare the percentage of T cells, natural killer (NK) cells and natural killer T (NKT) cells within decidual parietalis of normal pregnant controls (NP) and(More)
Commensal bacteria are crucial to maintain immune homeostasis in mucosal tissues and disturbances in their ecology can affect disease susceptibility. Here, we report evidence that commensal bacteria shape the efficiency of immune surveillance in mucosal tissues. Antibiotic-treated (Abt) mice were more susceptible to development of engrafted B16/F10 melanoma(More)
BACKGROUND CD4(+)CD25(+) regulatory T (Treg) cells and T-helper 17 (Th17) cells play important roles in acute cerebral infarction (ACI). Our previous findings have suggested that oxidized low-density lipoprotein (Ox-LDL) could influence Treg/Th17 ratio in ACI patients. However, the mechanisms are still not clear. METHODS AND RESULTS We evaluated the(More)
BACKGROUND chA21 is a novel tumor-inhibitory antibody which recognized subdomain I of HER2 extracellular domain with an epitope distinct from other HER2 antibodies. Previously, we demonstrated that chA21 inhibits human ovarian carcinoma cell line SKOV-3 growth in vitro and in vivo study. In this study, we further investigated the anti-angiogenic efficacy(More)
p185(her2/neu) belongs to the ErbB receptor tyrosine kinase family, which has been associated with human breast, ovarian, and lung cancers. Targeted therapies employing ectodomain-specific p185(her2/neu) monoclonal antibodies (mAbs) have demonstrated clinical efficacy for breast cancer. Our previous studies have shown that p185(her2/neu) mAbs are able to(More)
It was well studied that ErbB2 (HER2/p185(her2/neu)) overexpression in human malignant cancers correlates with poor prognosis and chemo-resistance. Although Trastuzumab (Herceptin) has been widely used in patients with ErbB2-overexpressing metastatic breast cancer, many patients either do not respond to Trastuzumab therapy or progress within 1 year of(More)

Human epidermal growth factor receptor 2 (HER2) is one of the most studied tumor-associated antigens for cancer immunotherapy. An engineered anti-HER-2 chimeric A21 antibody (chA21) is a chimeric antibody targeted to subdomain I of the HER2 extracellular domain. Here, we report the anti-tumor activity of the novel engineered monoclonal antibody humanized(More)
Embryonic development associated gene (EDAG), which is overexpressed in hematopoietic neoplasms and leukemia cell lines, has been reported to participate in the leukemia cell differentiation and proliferation. This study investigated whether retrovirus-mediated transfer of a siRNA against EDAG can reduce the growth of leukemia cells which highly express(More)
