Cytokine-Neuroantigen Fusion Proteins as a New Class of Tolerogenic, Therapeutic Vaccines for Treatment of Inflammatory Demyelinating Disease in Rodent Models of Multiple Sclerosis
(2012-08)Myelin-specific induction of tolerance represents a promising means to modify the course of autoimmune inflammatory demyelinating diseases such as multiple sclerosis (MS). Our laboratory has focused on a novel preclinical ... -
Cytokines and neuroantigens for treatment of immune disorders
(2017-05-10)The present invention provides methods of regulating an immunological disorder comprising administering to a subject an effective amount of (i) an autoimmune antigen in conjunction with (ii) an anti-inflammatory cytokine. ... -
Cytotoxic activity of the novel small molecule AKT inhibitor SC66 in hepatocellular carcinoma cells
(2015-01)Hepatocellular carcinoma (HCC) is characterized by limited response to current drug therapies. Here, we report that SC66, a novel AKT inhibitor, reduced cell viability in a dose- and time-dependent manner, inhibited colony ... -
Deficiency of a Sinorhizobium meliloti bacA Mutant in Alfalfa Symbiosis Correlates with Alteration of the Cell Envelope
(East Carolina University, 2002-10)The BacA protein is essential for the long-term survival of Sinorhizobium meliloti and Brucella abortus within acidic compartments in plant and animal cells, respectively. Since both the S. meliloti and B. abortus bacA ... -
DELINEATING THE MECHANISM OF AGGREGATE OR BIOFILM FORMATION IN THE LYME DISEASE SPIROCHETE BORRELIA BURGDORFERI
(East Carolina University, 2021-07-14)Borrelia burgdorferi, the spirochete causing Lyme disease, is transmitted to a vertebrate host by the bite of an infected Ixodes scapularis tick. The spirochete develops antibiotic resistance in humans likely due to the ... -
DELINEATING THE ROLE OF SOLUBLE CD25 AS AN IMMUNOREGULATORY MOLECULE THAT PROMOTES A LOW-ZONE IL-2 SIGNALING ENVIRONMENT FAVORABLE FOR THE SELECTION OF CD25HIGH FOXP3HIGH T CELLS
(East Carolina University, 2021-07-22)Autoimmune diseases develop due to the breakdown of tolerogenic mechanisms that normally maintain immune homeostasis. CD4+ CD25+ FOXP3+ regulatory T cells (Tregs) are critical in the maintenance of tolerance and the ... -
Development of small-molecule inhibitors of the initiating proteases, C1r and C1s, of the classical complement pathway
(East Carolina University, 2019-12-12)Complement is a proteolytic cascade that upon activation plays a key effector role in the innate immune system and acts to prime the adaptive immune response. During normal homeostatic events, complement is tightly regulated ... -
Differential regulation of the attachment of KSHV infected human B cells to ECM by KSHV encoded gB and cellular alpha-V integrins
(East Carolina University, 2008-07)Kaposi’s sarcoma-associated herpesvirus (KSHV) has two modes replication: latent and lytic replication. Reactivation from latency is dictated, in part, by the cell cycle. Herein, we have attempted to delineate the importance ... -
Direct Inhibition of RNAse T2 Expression by the HTLV-1 Viral Protein Tax
(2011-08)Adult T-cell leukemia (ATL) is one of the primary diseases caused by Human T-cell Leukemia Virus type 1 (HTLV-1) infection. The virally-encoded Tax protein is believed to initiate early events in the development of this ... -
Effect of in vitro transcription on cruciform stability.
(East Carolina University, 1990-05-11)We have investigated the effect of in vitro transcription on cruciform stability. Replicative form DNA of 4X174 strain ins6240, containing a 48 bp synthetic palindrome in the J-F intercistronic region, was supercoiled in ... -
Effects of Ectopic Expression of NGAL on Doxorubicin Sensitivity
(2012-10)Neutrophil gelatinase-associated lipocalin (NGAL, a.k.a Lnc2) is a member of the lipocalin family which has diverse roles including stabilizing matrix metalloproteinase-9 from auto-degradation and as siderocalins which are ... -
Effects of palindromes on in vivo DNA replication and mutagenesis in bacteriophage phi X174 RF DNA.
(East Carolina University, 1988-11-25)Bacteriophage IX174 mutants with insertions of palindromic DNA sequences are rapidly outgrown by competing wild-type phage (Muller & Turnage, J. Mol. Biol. 189: 285). The basis for this defect was investigated and found ... -
The Emerging Role of the Phosphatidylinositol 3-Kinase/ Akt/Mammalian Target of Rapamycin Signaling Network in Cancer Stem Cell Biology
(2010-08)The cancer stem cell theory entails the existence of a hierarchically organized, rare population of cells which are responsible for tumor initiation, self-renewal/maintenance, and mutation accumulation. The cancer stem ... -
Emerging targeted therapies for melanoma treatment (Review)
(2014-08)Cutaneous melanoma is an aggressive cancer with a poor prognosis for patients with advanced disease. The identification of several key molecular pathways implicated in the pathogenesis of melanoma has led to the development ... -
Enforced expression of HoxA9 in b-lineage all promotes survival and proliferation of leukemic cells
(East Carolina University, 2009)HoxA9 is frequently overexpressed in acute myeloid leukemia, myelodysplastic syndrome and a subset of acute lymphoblastic leukemia. In mouse models, HoxA9 has been shown to promote leukemogenesis. In spite of a seemingly ...
