Inflammatory conditions characterized by excessive peripheral immune responses are associated with diverse alterations in brain function, and brain-derived neural pathways regulate peripheral inflammation. Important aspects of this bidirectional peripheral immune - brain communication, including the impact of peripheral inflammation on brain region-specific cytokine responses, and brain cholinergic signaling (which plays a role in controlling peripheral cytokine levels) remain unclear. To provide insight, we studied gene expression of cytokines, immune cell markers and brain cholinergic system components in the cortex, cerebellum, brainstem, hippocampus, hypothalamus, striatum, and thalamus in mice following an intraperitoneal lipopolysaccharide injection. Endotoxemia was accompanied by elevated serum levels …

Expression Of Blimp-1 In Dendritic Cells Modulates The Innate Inflammatory Response In Dextran Sodium Sulfate-Induced Colitis, S. J. Kim, J. Goldstein, K. Dorso, M. Merad, L. Mayer, J. M. Crawford, P. K. Gregersen, B. Diamond

Journal Articles

A single nucleotide polymorphism of PRDM1, the gene encoding Blimp-1, is strongly associated with inflammatory bowel disease. Here, we demonstrate that Blimp-1 in CD103(+) dendritic cells (DCs) critically contributes to the regulation of macrophage homeostasis in the colon. Dextran sodium sulfate (DSS)-exposed Blimp-1(cko) mice with a deletion of Blimp-1 in CD103(+) DCs and CD11c(hi) macrophages exhibited severe inflammatory symptoms, pronounced weight loss, high mortality, robust infiltration of neutrophils in epithelial regions of the colon, an increased expression of proinflammatory cytokines and a significant decrease in CD103(+) DCs in the colon compared with DSS exposed wild-type (WT) mice. Purified colonic macrophages …

Purpose: The practice of "genomic" (or "personalized") medicine requires the availability of appropriate diagnostic testing. Our study objective was to identify the reasons for health systems to bring next-generation Sequencing into their clinical laboratories and to understand the process by which such decisions were made. Such information may be of value to other health systems seeking to provide next-generation sequencing-testing to their patient populations. Methods: A standardized open-ended interview was conducted With the laboratory medical directors and/or department of pathology chairs of 13 different academic institutions in 10 different states. Results: Genomic testing for cancer dominated the institutional decision making, …


Can Newly Developed, Rapid Immunochromatographic Antigen Detection Tests Be Reliably Used For The Laboratory Diagnosis Of Influenza Virus Infections?, J. J. Dunn, C. C. Ginocchio Jan 2014

Can Newly Developed, Rapid Immunochromatographic Antigen Detection Tests Be Reliably Used For The Laboratory Diagnosis Of Influenza Virus Infections?, J. J. Dunn, C. C. Ginocchio

Journal Articles

Five years ago, the Point-Counterpoint series was launched. The initial article asked about the role of rapid immunochromatographic antigen testing in diagnosis of influenza A virus 2009 H1N1 infection (1). Since that article, major changes have been made not only in immunochromatographic antigen detection (IAD) test for the influenza viruses but there also has been rapid development of commercially available nucleic acid amplification tests (NAATs) for influenza virus detection as well. Further, a novel variant of influenza A, H7N9, has emerged in Asia and H5N1 is also re-emergent. In this initial article, the editor of this series, Peter Gilligan, identified …

Journal Articles

Androgen receptor (AR), a steroid hormone receptor, is critical for prostate cancer growth. However, activation of AR by androgens can also lead to growth suppression and differentiation. Transcriptional cofactors play an important role in this switch between proliferative and anti-proliferative AR target gene programs. Transducin beta-like-related protein 1 (TBLR1), a core component of the nuclear receptor corepressor complex, shows both corepressor and coactivator activities on nuclear receptors, but little is known about its effects on AR and prostate cancer. We characterized TBLR1 as a coactivator of AR in prostate cancer cells and determined that the activation is dependent on both …

Journal Articles

Two variants of renal angiomyolipoma (AML)—classic and epithelioid—have been described. Although the epithelioid variant has been reported to demonstrate an aggressive clinical behavior, classic AML is usually benign. Herein, we report a case of a 42-year-old asymptomatic woman with a lipomatous variant of renal AML associated with an inferior vena cava thrombus managed with radical nephrectomy and caval thrombectomy.


Schwannoma Of The Cervical Esophagus, M. Ferrante, A. Khan, C. Fan, F. Z. Jelloul Jan 2014

Schwannoma Of The Cervical Esophagus, M. Ferrante, A. Khan, C. Fan, F. Z. Jelloul

Journal Articles

Esophageal schwannoma is a rare tumor first described in 1967 by Chaterlin and Fissore. These tumors are most commonly found incidentally or from diagnostic work up of dysphagia or dyspnea. This entity cannot be diagnosed on clinical or radiographic basis alone. Histology demonstrates palisading spindle cells, few if any mitotic figures, and a peripheral cuff of lymphoid cells. Immunohistochemically, tumor cells stain positive for S100, a characteristic marker of Schwann cells. Once diagnosed, surgical enucleation is the typical treatment method employed.


Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease), C. Q. Fan, J. M. Crawford Jan 2014

Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease), C. Q. Fan, J. M. Crawford

Journal Articles

Hepatic sinusoidal obstruction syndrome (SOS) is an obliterative venulitis of the terminal hepatic venules, which in its more severe forms imparts a high risk of mortality. SOS, also known as veno-occlusive disease (VOD), occurs as a result of cytoreductive therapy prior to hematopoietic stem cell transplantation (HSCT), following oxaliplatin-containing adjuvant or neoadjuvant chemotherapy for colorectal carcinoma metastatic to the liver and treated by partial hepatectomy, in patients taking pyrrolizidine alkaloid-containing herbal remedies, and in other particular settings such as the autosomal recessive condition of veno-occlusive disease with immunodeficiency (VODI). A central pathogenic event is toxic destruction of hepatic sinusoidal endothelial …

Papillary Adenocarcinoma In Situ Of The Skin: Report Of Four Cases, S. Chen, M. Asgari Jan 2014

Papillary Adenocarcinoma In Situ Of The Skin: Report Of Four Cases, S. Chen, M. Asgari

Journal Articles

Although rare isolated cases of adenocarcinoma in situ of skin have been reported in the literature, adenocarcinoma in situ of skin as a concept and as a diagnostic category has not been established in the field of dermatopathology. In this work, four cases of papillary adenocarcinoma in situ of the skin are presented. In addition, the notion that lesions previously reported in the medical literature under the term of "papillary eccrine adenoma" are actually adenocarcinoma in situ is discussed.
