The Asian corn borer (ACB), Ostrinia furnacalis (Lepidoptera: Crambidae), is a highly destructive pest of cultivated maize throughout East Asia. Bacillus thuringiensis (Bt) crystalline protein (Cry) toxins cause mortality by a mechanism involving pore formation or signal transduction following toxin binding to receptors along the midgut lumen of susceptible insects, but this mechanism and mutations therein that lead to resistance are not fully understood. In the current study, quantitative comparisons were made among midgut expressed transcripts from O...

BACKGROUND: Albuminuria is a marker of inflammation and an independent predictor of cardiovascular morbidity and mortality. The current study evaluated whether eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation attenuates progression of albuminuria in subjects with coronary artery disease. METHODS AND RESULTS: Two-hundred sixty-two subjects with stable coronary artery disease were randomized to either Lovaza (1.86 g of EPA and 1.5 g of DHA daily) or no Lovaza (control) for 1 year...

OBJECTIVE: Fractalkine (CX3CL1/FKN) is a chemokine that regulates chemotaxis and adhesion of CX3C chemokine receptor 1 (CX3CR1)-expressing inflammatory cells. We conducted the first phase 1/2, open-label, multiple ascending dose study of E6011, a humanized anti-FKN monoclonal antibody, in Japanese rheumatoid arthritis (RA) patients (clinicaltrial.gov identifier: NCT02196558). METHODS: Active RA patients with an inadequate response or intolerance to methotrexate or tumor necrosis factor (TNF) inhibitor received E6011 at week 0, 1, 2, and thereafter every 2 weeks for 12 weeks...

BACKGROUND AND AIMS: Tumor necrosis factor receptor type 1 (TNFR1) is associated with kidney disease and mortality risk in various populations. Whether or not kidney function mediates mortality risk is unknown. We evaluated associations of TNFR1 levels with measures of kidney function, cardiovascular events, and mortality in a population of veterans with stable ischemic heart disease. METHODS: TNFR1 was measured from baseline serum samples in the Heart and Soul Study; elevated levels were defined by the highest quartile (Q4, >3...

Perturbations in synaptic function could affect the normal behavior of an animal, making it important to understand the regulatory mechanisms of synaptic signaling. Previous work has shown that in Caenorhabditis elegans an immunoglobulin superfamily protein, RIG-3, functions in presynaptic neurons to maintain normal acetylcholine receptor levels at the neuromuscular junction (NMJ). In this study, we elucidate the molecular and functional mechanism of RIG-3. We demonstrate by genetic and BiFC (Bi-molecular Fluorescence Complementation) assays that presynaptic RIG-3 functions by directly interacting with the immunoglobulin domain of the nonconventional Wnt receptor, ROR receptor tyrosine kinase (RTK), CAM-1, which functions in postsynaptic body-wall muscles...

Acetylcholine (ACh) receptors (AChR) regulate neural circuit activity in multiple contexts. In humans, mutations in ionotropic acetylcholine receptor (iAChR) genes can cause neurological disorders, including myasthenia gravis and epilepsy. In Caenorhabditis elegans, iAChRs play multiple roles in the locomotor circuit. The cholinergic motor neurons express an ACR-2-containing pentameric AChR (ACR-2R) comprised of ACR-2, ACR-3, ACR-12, UNC-38, and UNC-63 subunits. A gain-of-function mutation in the non-α subunit gene acr-2 [acr-2(gf)] causes defective locomotion as well as spontaneous convulsions...

The objective of this study was to assess the effects of transport stress at high ambient temperatures on the oxidation status and the expression of essential elements responsible for the Ca transport (sarco- (endo-) plasmic reticulum Ca-ATPase (SERCA1) and the ryanodine receptor (RyR) in (PM) muscles of broilers. Briefly, Arbor Acres broiler chickens ( = 112) were randomly categorized into 2 treatments: unstressed control (C) and 0.5 h transport (T). Each treatment consisted of 8 replicates of 7 birds each...

BACKGROUND: In vitro experiments have revealed that toll-like receptor 4 (TLR4) pathway is involved in the progression of immunoglobulin A nephropathy (IgAN) by induction of proinflammatory cytokines. Evidence showed that, in other disease models, peroxisome proliferator-activated receptor-γ (PPAR-γ) agonists have been shown to exert anti-inflammatory effects through suppression of the expression and activity of TLR4. However, the interaction between PPAR-γ and TLR4 in IgAN has not been fully studied both in vitro and in vivo...

AIM: To assess efficacy and safety of fosdagrocorat (PF-04171327), a potential dissociated agonist of the glucocorticoid receptor, in rheumatoid arthritis (RA) patients. METHODS: This multicenter, double-blind, parallel-group, active- and placebo-controlled Phase 2 study (NCT00938587) randomized 86 patients (1 : 1 : 1 : 1) to receive fosdagrocorat 10 mg, fosdagrocorat 25 mg, prednisone 5 mg or placebo, all with stable background methotrexate therapy. The primary outcome was change from baseline in Disease Activity Score of 28 joints (DAS28-4[C-reactive protein (CRP)]) after 2 weeks of treatment...

OBJECTIVES: Despite the therapeutic value of current rheumatoid arthritis (RA) treatments, agents with alternative modes of action are required. Mavrilimumab, a fully human monoclonal antibody targeting the granulocyte-macrophage colony-stimulating factor receptor-α, was evaluated in patients with moderate-to-severe RA. METHODS: In a phase IIb study (NCT01706926), patients with inadequate response to ≥1 synthetic disease-modifying antirheumatic drug(s), Disease Activity Score 28 (DAS28)-C reactive protein (CRP)/erythrocyte sedimentation rate ≥3...

Nematode parasites infect ∼2 billion people world-wide. Infections are treated and prevented by anthelmintic drugs, some of which act on nicotinic acetylcholine receptors (nAChRs). There is an unmet need for novel therapeutic agents because of concerns about the development of resistance. We have selected Asu-ACR-16 from a significant nematode parasite genus, Ascaris suum, as a pharmaceutical target and nicotine as our basic moiety (EC50 6.21 ± 0.56 μM, Imax 82.39 ± 2.52%) to facilitate the development of more effective anthelmintics...

OBJECTIVE: To study the role of B lymphocytes in systemic sclerosis (SSc). METHODS: Peripheral B cell subpopulations and the production of interleukin-6 (IL-6) and transforming growth factor β (TGFβ) were analyzed using flow cytometry and multiplex assay. The fibroblast proliferation rate upon incubation with supernatants from B cells isolated from SSc patients or healthy controls was assessed using XTT, bromodeoxyuridine, and Ki-67. Collagen production was assessed using a collagen assay...

BACKGROUND/PURPOSE: Neuropsychiatric (NP) events are found in patients with rheumatic diseases, commonly in systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). The standard nomenclature and case definitions for 19 NPSLE syndromes by the American College of Rheumatology (ACR) Committee on Research cover a wide range of NP events seen in both SLE and SS. Despite advances in the understanding of SLE and SS, NP syndromes continue to pose diagnostic challenges. Correct attribution of NP events is critical in determining the correct treatment and prognosis...

BACKGROUND: The presence of antibodies to angiotensin type 1 receptor (AT1R) and endothelin type A receptor (ETAR) is associated with allograft rejection in kidney and heart transplantation. The aim of our study was to determine the impact of AT1R and ETAR antibodies on graft outcome in lung transplantation. METHODS: Pretransplant and posttransplant sera from 162 lung recipients transplanted at 3 centers between 2011 and 2013 were tested for antibodies to AT1R and ETAR by the enzyme-linked immunosorbent assay (ELISA) assay...

PURPOSE: IFN-γ is a protypical proinflammatory cytokine that plays a central role in inflammation and acute graft rejection. Accumulating evidence indicates that IFN-γ can exert previously unexpected immunoregulatory activities. However, little is known about the role of IFN-γ secreted by Th1-like regulatory T cells in human kidney transplantation. METHODS: To determine the function of IFN-γ in acute T cell-mediated renal allograft rejection (ACR), we examined serum cytokine expression profiles in ACR patients by human cytokine multiplex immunoassay and analyzed the cellular origins of IFN-γ in peripheral blood and renal allograft biopsies from ACR cases and controls by flow cytometry and immunohistochemistry, respectively...
