PI(4,5)P2 concentration at the APC side of the Immunological Synapse is Required for Effector T cell Function
(East Carolina University, 2009-05-01)
Little is known about the signaling that occurs in an antigen presenting cell (APC) during contact with a T cell. Here we report the concentration of the signaling lipid, PI(4,5)P2, at the APC side of the immunological ...
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 ...

Raf-Induced Vascular Endothelial Growth Factor Augments Kaposi's Sarcoma-Associated Herpesvirus Infection
(East Carolina University, 2004-12)
Recombinant green fluorescent protein encoding Kaposi’s sarcoma-associated herpesvirus (rKSHV.152) infection of -estradiol stimulated human foreskin fibroblasts (HFF) or HFF/ B-Raf[FF]:ER (expressing a weaker form of ...
The Transfer Origin for Bacteroides Mobilizable Transposon Tn4555 Is Related to a Plasmid Family from Gram-Positive Bacteria
(East Carolina University, 1998-01)
Conjugal transfer of Bacteroides mobilizable transposon Tn4555 was examined with an Escherichia coli-based assay system. It was shown that mobilization required the cis-acting oriTTn region and that the Tn4555 mobATn gene ...
Physical and Functional Interactions between the Herpes Simplex Virus UL15 and UL28 DNA Cleavage and Packaging Proteins
(East Carolina University, 1999-02)
Herpes simplex virus (HSV) DNA is cleaved from concatemers and packaged into capsids in infected cell nuclei. This process requires seven viral proteins, including UL15 and UL28. UL15 expressed alone displays a nuclear ...
Cloning and Characterization of the Pseudomonas aeruginosa zwf Gene Encoding Glucose-6-Phosphate Dehydrogenase, an Enzyme Important in Resistance to Methyl Viologen (Paraquat)
(East Carolina University, 1998-04)
In this study, we cloned the Pseudomonas aeruginosa zwf gene, encoding glucose-6-phosphate dehydrogenase (G6PDH), an enzyme that catalyzes the NAD1- or NADP1-dependent conversion of glucose-6-phosphate to 6-phosphogluconate. ...
Generation and characterization of the humoral immune response to DNA immunization with a chimeric beta-amyloid-interleukin-4 minigene
(East Carolina University, 2003-12)
Active immunization with fibrillar beta-amyloid peptide (AB42) as well as passive transfer of anti-AB antibodies significantly reduces AB plaque deposition, neuritic dystrophy, and astrogliosis in the brain of mutant amyloid ...
Inhibition of Quorum Sensing by a Pseudomonas aeruginosa dksA Homologue
(East Carolina University, 2001-03)
The Pseudomonas aeruginosa las (lasR-lasI) and rhl (rhlR-rhlI) quorum-sensing systems regulate the expression of several virulence factors, including elastase and rhamnolipid. P. aeruginosa strain PR1-E4 is a lasR deletion ...
The Global Carbon Metabolism Regulator Crc Is a Component of a Signal Transduction Pathway Required for Biofilm Development by Pseudomonas aeruginosa
(East Carolina University, 2000-01)
The transition from a planktonic (free-swimming) existence to growth attached to a surface in a biofilm occurs in response to environmental factors, including the availability of nutrients. We show that the catabolite ...
