PURPOSE A subset of patients with anterior uveitis express the marker, perinuclear anti-neutrophil cytoplasmic antibody (pANCA). In this study, recombinantly isolated pANCA monoclonal antibodies were used to search for ocular cells expressing the pANCA antigen. METHODS Paraffin sections of human ocular tissues obtained after death were analyzed by immunohistochemistry to identify cell types e...

Proteus species are well-known opportunistic pathogens frequently associated with skin wound and urinary tract infections in humans and animals. O antigen diversity is important for bacteria to adapt to different hosts and environments, and has been used to identify serotypes of Proteus isolates. At present, 80 Proteus O-serotypes have been reported. Although the O antigen structures of most Pr...

INTRODUCTION Epithelial ovarian cancer is recognized to be heterogeneous but is currently treated with a single treatment strategy. Successful patient stratification of emerging chemotherapy agents is dependent upon the availability of reliable biomarkers indicative of the entire tumor. AIM The aim of this study was to evaluate intertumor and intratumor heterogeneity within a series of epithe...

Cancer immunotherapy has emerged as a mainstream therapy option in the battle against cancer. Pre-clinical data demonstrates the ability of immunotherapy to harness the immune system to fight disseminated malignancy. Clinical translation has failed to recapitulate the promising results of pre-clinical studies although there have been some successes. In this review we explore some of the short-c...

objective(s) while the nucleus accumbens and the striatum have received much attention regarding their roles in stereotyped behaviors, the role of the medial prefrontal cortex (mpfc) has not been investigated to the same degree. few studies have reported the role of the mpfc in dopaminergic induction of locomotor hyperactivity. the mpfc is a heterogeneous area (the anterior cingulated, prelimbi...

Numerous microbes establish persistent infections, accompanied by antigen-specific CD8 T cell activation. Pathogen-specific T cells in chronically infected hosts are often phenotypically and functionally variable, as well as distinct from T cells responding to nonpersistent infections; this phenotypic heterogeneity has been attributed to an ongoing reencounter with antigen. Paradoxically, maint...

The immunoperoxidase localization of carcinoembryonic antigen (CEA) determinants was studied in colonic adenocarcinomas using four murine monoclonal antibodies to CEA in a bridged avidin:biotin technique. One of the monoclonal antibodies, NP-1, recognizes a CEA epitope shared with the nonspecific cross-reacting antigen and meconium antigen. Two others, NP-2 and NP-3, discriminate two separate C...

Several monoclonal antibodies bind in a highly selective manner to tumor-associated glycoforms of MUC1. We set out to exploit this by developing a MUC1-specific chimeric antigen receptor. Difficulties were encountered in this endeavor, owing to MUC1-imposed steric hindrance and antigenic heterogeneity. These issues were addressed by the iterative engineering of all components of the fusion rece...
