Base-By-Base: Single nucleotide-level analysis of whole viral genome alignments
(East Carolina University, 2004-07-14)
Background: With ever increasing numbers of closely related virus genomes being sequenced, it has become desirable to be able to compare two genomes at a level more detailed than gene content because two strains of an ...
Autocrine production of extracellular catalase prevents apoptosis of the human CEM T-cell line in serum-free medium.
(East Carolina University, 1993-05-15)
CCRF-CEM is a human T-cell line originally isolated from a child with acute lymphoblastic leukemia. At cell densities > 2 x 10 cells per ml, CEM cells grow in serum-free medium, but at lower cell densities the cultures ...
The Brucella abortus Cu,Zn Superoxide Dismutase Is Required for Optimal Resistance to Oxidative Killing by Murine Macrophages and Wild-Type Virulence in Experimentally Infected Mice
(East Carolina University, 2005-05)
Two-dimensional gel electrophoretic analysis of cell lysates from Brucella abortus 2308 and the isogenic hfq mutant Hfq3 revealed that the RNA binding protein Hfq (also known as host factor I or HF-I) is required for the ...
Using death to one's advantage: HIV modulation of apoptosis
(East Carolina University, 2001-03)
Infection by human immunodeficiency virus (HIV) is associated with an early immune dysfunction and progressive destruction of CD4+ T lymphocytes. This progressive disappearance of T cells leads to a lack of immune control ...
PI3K activation is associated with intracellular sodium/iodide symporter protein expression in breast cancer
(East Carolina University, 2007-07-25)
Background: The sodium/iodide symporter (NIS) is a membrane glycoprotein mediating active iodide uptake in the thyroid gland and is the molecular basis for radioiodide imaging and therapeutic ablation of thyroid carcinomas. ...
Interference with Pseudomonas quinolone signal synthesis inhibits virulence factor expression by Pseudomonas aeruginosa
(East Carolina University, 2001-09-25)
Pseudomonas aeruginosa is an opportunistic pathogen that controls numerous virulence factors through intercellular signals. This bacterium has two quorum-sensing systems (las and rhl), which act through the intercellular ...
A Wzx-Wzy-like Polysaccharide Biosynthetic Pathway Contributes to Virulence in Brucella abortus 2308 through an Unknown Mechanism
(East Carolina University, 2022-08-05)
Brucella abortus is an intracellular pathogen that causes spontaneous abortion in cattle and undulant fever in humans. As a member of the a-proteobacteria, B. abortus is closely related to the bacterial species Caulobacter ...
TLR-4 agonism induces CD25+ MHCIIhigh dendritic cells in association with tolerogenic antigen recognition
(East Carolina University, 2022-12-06)
Autoimmune disease is a result of the breakdown in immunological self-tolerance leading to destruction of self-tissues mediated by the aberrant immune attack. In Multiple Sclerosis (MS), CD4+ T cells mediate destruction ...
