A synthetic urinary probe–coated nanoparticles sensitive to fibroblast activation protein α for solid tumor diagnosis
We developed fibroblast activation protein α (FAPα)-sensitive magnetic iron oxide nanoparticles (MNPs) by conjugating a substrate-reporter tandem peptide as a synthetic biomarker to the surface of MNPs (marker-MNPs). In vitro, the marker-MNPs showed stability when treated with serum or urine and exhibited high susceptibility and specificity for FAPα enzyme and 3T3/FAPα cell line. Furthermore, t...
متن کاملAbrogation of fibroblast activation protein enzymatic activity attenuates tumor growth.
Tumor-associated fibroblasts are functionally and phenotypically distinct from normal fibroblasts that are not in the tumor microenvironment. Fibroblast activation protein is a 95 kDa cell surface glycoprotein expressed by tumor stromal fibroblasts, and has been shown to have dipeptidyl peptidase and collagenase activity. Site-directed mutagenesis at the catalytic site of fibroblast activation ...
متن کاملTumor immunotherapy targeting fibroblast activation protein, a product expressed in tumor-associated fibroblasts.
Murine studies have shown that immunologic targeting of the tumor vasculature, a key element of the tumor stroma, can lead to protective immunity in the absence of significant pathology. In the current study, we expand the scope of stroma-targeted immunotherapy to antigens expressed in tumor-associated fibroblasts, the predominant component of the stroma in most types of cancer. Mice were immun...

background tnf-α is one of the most potent cytokines in proinflammatory reactions. results one hundred and twenty children with acute pyelonephritis were evaluated. urinary tnf-α/cr was 0.0051 ± 0.00083 pg/g creatinine. the authors found out a significant difference in urinary tnf-α/cr between patients who have normal and abnormal levels of urine leukocytes, urine protein, urine culture, erythr...
متن کاملExpansion of a highly sensitive and specific ELISA test for diagnosis of hydatidosis using recombinant EgB8/2 protein
Objective(s): Hydatidosis is a zoonotic infection and endemic in Iran. Due to the serological cross-reactivity (of sera) with other parasitic infection, diagnosis of hydatid cyst is considered to be problematic. In this regard, application of recombinant antigens improves serological diagnosis for human hydatidosis. Here, we present an ELISA test based on B8/2 recombinant antigen of Echinococcu...
