Neutralizing Interleukin-6 In Tumor-Bearing Mice Does Not Abrogate Behavioral Fatigue Induced By Lewis Lung Carcinoma, Kiersten Scott, Thien Trong Phan, A Phillip West, Cullen M Taniguchi, Robert Dantzer

Faculty, Staff and Student Publications

Tumor growth is associated with metabolic reprogramming of various organs including the liver. This metabolic reprogramming is responsible for the development of behavioral fatigue represented by decreased voluntary wheel running in a murine model of lung cancer. To determine whether interleukin (IL-)6 induced by the tumor is responsible for the metabolic reprogramming, mice injected with Lewis lung carcinoma cells in the flank were treated with an anti-mouse IL-6 monoclonal neutralizing antibody using a 2 × 2 factorial design (+/- tumor and +/- anti-IL-6 antibody). Endpoints were represented by behavioral, metabolic and immune phenotypes. Despite its ability to abrogate the increase …

RATIONALE: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.

OBJECTIVE: We sought to study the role of common single nucleotide polymorphisms (SNPs) in risk for D-TGA.

METHODS AND RESULTS: We conducted a genome-wide association study in an international set of 1,237 patients …

Effects Of Road Traffic On The Accuracy And Bias Of Low-Cost Particulate Matter Sensor Measurements In Houston, Texas, Arch Carson

Faculty, Staff and Student Publications

Although PM2.5 measurements of low-cost particulate matter sensors (LCPMS) generally show moderate and strong correlations with those from research-grade air monitors, the data quality of LCPMS has not been fully assessed in urban environments with different road traffic conditions. We examined the linear relationships between PM2.5 measurements taken by an LCPMS (Dylos DC1700) and two research grade monitors, a personal environmental monitor (PEM) and the GRIMM 11R, in three different urban environments, and compared the accuracy (slope) and bias of these environments. PM2.5 measurements were carried out at three locations in Houston, Texas (Clinton Drive largely with diesel trucks, US-59 …

The Power And Challenge Of Lipid (A)Symmetry Across The Membrane And Cell

Faculty, Staff and Student Publications

Current treatments for substance use disorders (SUDs) are far from ideal, with no U.S. Food and Drug Administration-approved pharmacotherapies to treat stimulant and other use disorders. New approaches are urgently needed to combat the increasing prevalence of SUDs and overdose deaths. It is widely accepted that addiction is a chronic disease of the brain involving changes in neural circuitry associated with cognitive and reward functioning. Brain stimulation techniques are novel methods that can modulate these circuits directly and thus hold considerable promise for treating SUDs.

B Cell Receptor Isotypes Differentially Associate With Cell Signaling, Kinetics, And Outcome In Chronic Lymphocytic Leukemia, Andrea N Mazzarello, Eva Gentner-Göbel, Marcus Dühren-Von Minden, Tatyana N Tarasenko, Antonella Nicolò, Stefano Vergani, Davide Bagnara, Kanti R Rai, Jan A Burger, Peter J Mcguire, Palash C Maity, Hassan Jumaa, Nicholas Chiorazzi

Faculty, Staff and Student Publications

In chronic lymphocytic leukemia (CLL), the B cell receptor (BCR) plays a critical role in disease development and progression, as indicated by the therapeutic efficacy of drugs blocking BCR signaling. However, the mechanism(s) underlying BCR responsiveness are not completely defined. Selective engagement of membrane IgM or IgD on CLL cells, each coexpressed by more than 90% of cases, leads to distinct signaling events. Since both IgM and IgD carry the same antigen-binding domains, the divergent actions of the receptors are attributed to differences in immunoglobulin (Ig) structure or the outcome of signal transduction. We showed that IgM, not IgD, level …

Cxcl10 Chemokine Regulates Heterogeneity Of The Cd8+ T Cell Response And Viral Set Point During Chronic Infection, Aleksandra J Ozga, Melvyn T Chow, Mateus E Lopes, Rachel L Servis, Mauro Di Pilato, Jeffrey Lian, Andrew D Luster

Faculty, Staff and Student Publications

CD8+ T cells responding to chronic infection adapt an altered differentiation program that provides some restrain on pathogen replication yet limits immunopathology. This adaptation is imprinted in stem-like cells and propagated to their progeny. Understanding the molecular control of CD8+ T cell differentiation in chronic infection has important therapeutic implications. Here, we found that the chemokine receptor CXCR3 was highly expressed on viral-specific stem-like CD8+ T cells and that one of its ligands, CXCL10, regulated the persistence and heterogeneity of responding CD8+ T cells in spleens of mice chronically infected with lymphocytic choriomeningitis virus. CXCL10 was produced by inflammatory monocytes …

Epigenetic Silencing Of Tumor Suppressor Lncrna Nkila: Implication On Nf-Κb Signaling In Non-Hodgkin’S Lymphoma, Min-Yue Zhang, George Calin, Ming-Dan Deng, Rex K H Au-Yeung, Lu-Qian Wang

Faculty, Staff and Student Publications

The long non-coding RNA (lncRNA) NKILA, localized to 20q13.31, is a negative regulator of NF-κB signaling implicated in carcinogenesis. As a CpG island is embedded in the promoter region of NKILA, it is hypothesized as a tumor suppressor lncRNA silenced by promoter DNA methylation in non-Hodgkin’s lymphoma (NHL). By pyrosequencing-verified methylation-specific PCR, NKILA methylation was detected in 1/10 (10%) NHL cell lines, but not in normal peripheral blood buffy coats or tonsils. NKILA methylation correlated with the repression of NKILA in cell lines. Hypomethylation treatment with 5-Aza-2′-deoxycytidine resulted in promoter demethylation and the re-expression of NKILA. In 102 …

Reinvigoration of antitumor immunity remains an unmet challenge. Our retrospective analyses revealed that cancer patients who took antihistamines during immunotherapy treatment had significantly improved survival. We uncovered that histamine and histamine receptor H1 (HRH1) are frequently increased in the tumor microenvironment and induce T cell dysfunction. Mechanistically, HRH1-activated macrophages polarize toward an M2-like immunosuppressive phenotype with increased expression of the immune checkpoint VISTA, rendering T cells dysfunctional. HRH1 knockout or antihistamine treatment reverted macrophage immunosuppression, revitalized T cell cytotoxic function, and restored immunotherapy response. Allergy, via the histamine-HRH1 axis, facilitated tumor growth and induced immunotherapy resistance in mice and humans. …
