CD11c+ dendritic cells (DCs) exert a critical role as antigen-presenting cells in regulating pathogenic T cells in multiple sclerosis (MS). To determine whether the therapeutic benefit of interferon (IFN)-β treatment for MS is in part influenced by IFN regulation of DC function, we examined the immunophenotype of DCs derived from IFN-β(+/+) and IFN-β(-/-) mice using a myelin oligodendrocyte glycoprotein (MOG) peptide-induced mouse model of MS, experimental autoimmune encephalomyelitis (EAE). Our earlier work identified that IFN-β(-/-) mice exhibit earlier onset and more rapid progression of neurologic impairment compared with IFN-β(+/+) mice...

Angiotensin II (AngII) promotes hypertension, atherogenesis, vascular aneurysm and impairs post-ischemic cardiac remodeling through concerted roles on vascular cells, monocytes and T lymphocytes. However, the role of AngII in B lymphocyte responses is largely unexplored. Here, we show that chronic B cell depletion (Baffr deficiency) significantly reduces atherosclerosis in Apoe (-/-) mice infused with AngII. While adoptive transfer of B cells in Apoe (-/-) /Baffr (-/-) mice reversed atheroprotection in the absence of AngII, infusion of AngII in B cell replenished Apoe (-/-) /Baffr (-/-) mice unexpectedly prevented the progression of atherosclerosis...

Adoptive therapy with T cell receptor (TCR)-engineered T cells has shown promising results in the treatment of patients with tumors, and the number of TCRs amenable for clinical testing is expanding rapidly. Notably, adoptive therapy with T cells is challenged by treatment-related side effects, which calls for cautious selection of target antigens and TCRs that goes beyond their mere ability to induce high T cell reactivity. Here, we propose a sequence of in vitro assays to improve selection of TCRs, and exemplify risk assessments of on-target as well as off-target toxicities using TCRs directed against Cancer Germline Antigens...

OBJECTIVE Blood loss and moderate anemia are common in patients with traumatic brain injury (TBI). However, despite evidence of the ill effects and expense of the transfusion of packed red blood cells, restrictive transfusion practices have not been universally adopted for patients with TBI. At a Level I trauma center, the authors compared patients with TBI who were managed with a restrictive (target hemoglobin level > 7 g/dl) versus a liberal (target hemoglobin level > 10 g/dl) transfusion protocol. This study evaluated the safety and cost-efficiency of a hospital-wide change to a restrictive transfusion protocol...

BACKGROUND: Intestinal fibrosis resulting in (sub)obstruction is a common complication of Crohn's disease (CD). Rho kinases (ROCKs) play multiple roles in TGFβ1-induced myofibroblast activation that could be therapeutic targets. Because systemic ROCK inhibition causes cardiovascular side-effects, we evaluated the effects of a locally acting ROCK inhibitor (AMA0825) on intestinal fibrosis. METHODS: Fibrosis was assessed in mouse models using dextran sulfate sodium and adoptive T cell transfer...

Cell immunotherapy, as an important mean of tumor therapy, infuses a large number of immune effector cells amplified in vitro to the patients, resulting in the anti-tumor effect. There have been a series techniques of cell immunotherapy, including T lymphocyte therapy, dendritic cell-based immune cell therapy, natural killer cell therapy, gamma delta T cell therapy and so on. The preparation and culture conditions, anti-tumor mechanism, target cells etc of these immune cells are not the same, the each with its advantages and disadvantages...

BACKGROUND: Despite TMS wide adoption, its spatial and temporal patterns of neuronal effects are not well understood. Although progress has been made in predicting induced currents in the brain using realistic finite element models (FEM), there is little consensus on how a magnetic field of a typical TMS coil should be modeled. Empirical validation of such models is limited and subject to several limitations. METHODS: We evaluate and empirically validate models of a figure-of-eight TMS coil that are commonly used in published modeling studies, of increasing complexity: simple circular coil model; coil with in-plane spiral winding turns; and finally one with stacked spiral winding turns...

Structure determination and prediction pose a major challenge to computational material science, demanding efficient global structure search techniques tailored to identify promising and relevant candidates. A major bottleneck is the fact that, due to the many combinatorial possibilities, there are too many possible geometries to be sampled exhaustively. Here, an innovative computational approach to overcome this problem is presented, that explores the potential energy landscape of commensurate organic/inorganic interfaces where the orientation and conformation of the molecules in the tightly packed layer is close to a favorable geometry adopted by isolated molecules on the surface...

Vasoactive intestinal peptide (VIP) is a neuroendocrine peptide hormone that has potent anti-inflammatory activities. VIP signaling through its receptor VPAC1 on T cells leads to reduced proliferation and a reduction in pro-inflammatory cytokine secretion. We report here that inhibition of the VIP pathway with a peptide antagonist significantly enhances a T-cell-dependent, autologous anti-leukemia response in murine models of acute myeloid leukemia and T lymphoblastic leukemia. Subcutaneous administration of the VIP antagonist, VIPhyb, resulted in reduced tumor burden and significantly enhanced survival (30-50% survival) over vehicle-treated controls (0-20% survival)...

Transfer of T cell receptors (TCR) specific for tumor-associated antigens is a promising approach for cancer immunotherapy. We developed the TCR gene editing technology, that is based on the knockout of the endogenous TCR α and β genes, followed by the introduction of tumor-specific TCR genes, and that proved safer and more effective than conventional TCR gene transfer. While successful, complete editing requires extensive cell manipulation and four transduction procedures. Here we propose a novel and clinically feasible 'single TCR editing' (SE) approach, based on the disruption of the endogenous TCR α chain only, followed by the transfer of genes encoding for a tumor specific TCR...

OBJECTIVES: We designed a pilot study to evaluate safety and feasibility of an inexpensive and simple approach to intracoronary hemodilution during primary angioplasty (PPCI) to reduce reperfusion injury. INTRODUCTION: Early revascularization in acute myocardial infarction decreases infarct size and improves outcomes. However, abrupt restoration of coronary flow results in myocardial reperfusion injury and increased final infarct size. Dilution of coronary blood during revascularization may help reduce this damage...

Oncoimmunology (or immunooncology) is a burgeoning specialty of precision ("personalized") medicine designed to heighten the antitumor response of the immune system against molecules expressed excessively or only by tumor cells. This focus is necessary, as cancers are polyclonal tissues comprised of antigenically heterogeneous cells, the exact composition of which is shaped by the balance between antitumor immunity and tumor-promoting inflammation. Key targets include enhancing immune system (especially T cell) reactivity, inhibiting immune checkpoints, and promoting tumor cytolysis...

Phthalate esters (PEs) are one of the environmentally active organic pollutants capable of causing endocrine disruption. The levels of PE congeners were determined in the influent and effluent from Covenant Oxidation Pond (COP) and Ikeja Wastewater Treatment Plant (IWWTP). Standard methods were adopted for determining the physical and chemical parameters of the water samples. The water samples for PE congener's determination were collected, acidified and stored at 4 °C prior to liquid-liquid extraction and analysis by gas chromatograph...
