The Cholera Toxin A1(3) Subdomain Is Essential For Interaction With Adp-Ribosylation Factor 6 And Full Toxic Activity But Is Not Required For Translocation From The Endoplasmic Reticulum To The Cytosol, Ken Teter, Michael G. Jobling, Danielle Sentz, Randall K. Holmes Jan 2006

The Cholera Toxin A1(3) Subdomain Is Essential For Interaction With Adp-Ribosylation Factor 6 And Full Toxic Activity But Is Not Required For Translocation From The Endoplasmic Reticulum To The Cytosol, Ken Teter, Michael G. Jobling, Danielle Sentz, Randall K. Holmes

Faculty Bibliography 2000s

Cholera toxin (CT) moves from the plasma membrane to the endoplasmic reticulum (ER) by retrograde vesicular traffic. In the ER, the catalytic CTA1 polypeptide dissociates from the rest of the toxin and enters the cytosol by a process that involves the quality control mechanism of ER-associated degradation (ERAD). The cytosolic CTA1 then ADP ribosylates Gs alpha, resulting in adenylate cyclase activation and intoxication of the target cell. It is hypothesized that the C-terminal A1(3) subdomain of CTA1 plays two crucial roles in the. p intoxication process: (i) it contains a hydrophobic domain that triggers the ERAD mechanism and (ii) it …

Faculty Bibliography 2000s

Collapsin response mediator protein 1 ( CRMP1) is one of the CRMP family members that mediates signal transduction of axon guidance molecules. Here, we show evidence that CRMP1 is involved in Reelin ( Reln) signaling to regulate neuronal migration in the cerebral cortex. In crmp1(-/-) mice, radial migration of cortical neurons was retarded. This phenotype was not observed in the sema3A(-/-) and crmp1(+/+); sema3A(+/+) cortices. However, CRMP1 was colocalized with disabled- 1 ( Dab1), an adaptor protein in Reln signaling. In the Reln(rl/rl) cortex, CRMP1 and Dab1 were expressed at a higher level, yet tyrosine phosphorylated at a lower level. …

Characterization Of The Ifn-Gamma T-Cell Responses To Immediate Early Antigens In Humans With Genital Herpes, Ralph P. Braun, Lendon G. Payne, Lichun Dong

Faculty Bibliography 2000s

Background: The IFN-gamma ELISPOT assay has been used to examine the T-cell repertoire for many disease states in humans but, as yet, not genital herpes. Using overlapping synthetic peptide libraries, an IFN-gamma ELISPOT assay was established that could measure CD4 and CD8 T-cell responses to HSV-2 antigens in patients with genital herpes. Results: In unexpanded T-cells isolated from peripheral blood, CD4 responses were readily measured against four immediate early antigens (ICP0, ICP4, ICP22 and ICP27), VP22 and gD. The CD4 responses were characterized by a low number of positive cells which produced large ELISPOTs. CD4 responses had a broad specificity …

Mitochondrial Uncoupling Protein-4 Regulates Calcium Homeostasis And Sensitivity To Store Depletion-Induced Apoptosis In Neural Cells, Sic. L. Chan, Dong Liu, George A. Kyriazis, Pamela Bagisyao, Xin Ouyang, Mark P. Mattson

Faculty Bibliography 2000s

An increase in the cytoplasmic-free Ca2+ concentration mediates cellular responses to environmental signals that influence a range of processes, including gene expression, motility, secretion of hormones and neurotransmitters, changes in energy metabolism, and apoptosis. Mitochondria play important roles in cellular Ca2+ homeostasis and signaling, but the roles of specific mitochondrial proteins in these processes are unknown. Uncoupling proteins (UCPs) are a family of proteins located in the inner mitochondrial membrane that can dissociate oxidative phosphorylation from respiration, thereby promoting heat production and decreasing oxyradical production. Here we show that UCP4, a neuronal UCP, influences store-operated Ca2+ entry, a process in …

Faculty Bibliography 2000s

Twenty-four putative lipase/esterase genes of Mycobacterium tuberculosis H37Rv were expressed in Escherichia coli and assayed for long-chain triacylglycerol (TG) hydrolase activity. We show here that the product of Rv3097c (LIPY) hydrolyzed long-chain TG with high specific activity. LIPY was purified after solubilization from inclusion bodies; the enzyme displayed a K-m of 7.57 mM and V-max of 653.3 nmol/mg/min for triolein with optimal activity between pH 8.0 and pH 9.0. LIPY was inhibited by active serine-directed reagents and was inactivated at temperatures above 37 degrees C. Detergents above their critical micellar concentrations and divalent cations inhibited the activity of LIPY. The …

Cole, Hong Lu, Xuxia Yan, Norelle L. Daly, David J. Craik, Shibo Jiang, Robert I. Lehrer, Robert Blumenthal

Faculty Bibliography 2000s

Retrocyclin-1, a 0-defensin, protects target cells from human immunodeficiency virus, type 1 (HIV-1) by preventing viral entry. To delineate its mechanism, we conducted fusion assays between susceptible target cells and effector cells that expressed HIV-1 Env. Retrocyclin-1 (4 mu M) completely blocked fusion mediated by HIV-1 Envs that used CXCR4 or CCR5 but had little effect on cell fusion mediated by HIV-2 and simian immunodeficiency virus Envs. Retrocyclin-1 inhibited HIV-1 Env-mediated fusion without impairing the lateral mobility of CD4, and it inhibited the fusion of CD4-deficient cells with cells bearing CD4-independent HIV-1 Env. Thus, it could act without cross-linking membrane …

Analysis Of Proline Reduction In The Nosocomial Pathogen Clostridium Difficile, Sarah Jackson, Mary Calos, Andrew Myers, William T. Self

Faculty Bibliography 2000s

Clostridium difficile, a proteolytic strict anaerobe, has emerged as a clinically significant nosocomial pathogen in recent years. Pathogenesis is due to the production of lethal toxins, A and B, members of the large clostridial cytotoxin family. Although it has been established that alterations in the amino acid content of the growth medium affect toxin production, the molecular mechanism for this observed effect is not yet known. Since there is a paucity of information on the amino acid fermentation pathways used by this pathogen, we investigated whether Stickland reactions might be at the heart of its bioenergetic pathways. Growth of C …
