Adenovirus F protein as a delivery vehicle for botulinum B.
(BMC Immunol, 2010-07-07)BACKGROUND: Immunization with recombinant carboxyl-terminal domain of the heavy chain (Hc domain) of botulinum neurotoxin (BoNT) stimulates protective immunity against native BoNT challenge. Most studies developing a botulism ... -
An immunoglobulin C kappa-reactive single chain antibody fusion protein induces tolerance through receptor editing in a normal polyclonal immune system.
(J Exp Med, 2005-03-07)Understanding immune tolerance mechanisms is a major goal of immunology research, but mechanistic studies have generally required the use of mouse models carrying untargeted or targeted antigen receptor transgenes, which ... -
ARFGAP1 promotes the formation of COPI vesicles, suggesting function as a component of the coat.
(J Cell Biol, 2002-10-14)The role of GTPase-activating protein (GAP) that deactivates ADP-ribosylation factor 1 (ARF1) during the formation of coat protein I (COPI) vesicles has been unclear. GAP is originally thought to antagonize vesicle formation ... -
Control of cyclin B1 localization through regulated binding of the nuclear export factor CRM1.
(Genes Dev, 1998-07-15)Activation of the Cyclin B/Cdc2 kinase complex triggers entry into mitosis in all eukaryotic cells. Cyclin B1 localization changes dramatically during the cell cycle, precipitously transiting from the cytoplasm to the nucleus ... -
Costimulation blockade alters germinal center responses and prevents antibody-mediated rejection.
(Am J Transplant, 2014-01)De novo donor-specific antibody (DSA) after organ transplantation promotes antibody-mediated rejection (AMR) and causes late graft loss. Previously, we demonstrated that depletion using anti-CD3 immunotoxin combined with ... -
Cytotoxicity of alpha-particle-emitting astatine-211-labelled antibody in tumour spheroids: no effect of hyperthermia.
(Br J Cancer, 1998-03)The high linear energy transfer, alpha-particle-emitting radionuclide astatine-211 (211At) is of interest for certain therapeutic applications; however, because of the 55- to 70-microm path length of its alpha-particles, ... -
Functionally active targeting domain of the beta-adrenergic receptor kinase: an inhibitor of G beta gamma-mediated stimulation of type II adenylyl cyclase.
(Proc Natl Acad Sci U S A, 1994-04-26)The beta-adrenergic receptor kinase (beta ARK) phosphorylates its membrane-associated receptor substrates, such as the beta-adrenergic receptor, triggering events leading to receptor desensitization. beta ARK activity is ... -
Interleukin 21 (IL-21) regulates chronic allograft vasculopathy (CAV) in murine heart allograft rejection.
(PloS one, 2019-01)IL-21 is the most recently discovered common gamma-chain cytokine that promotes persistent T-cell responses in chronic infections, autoimmunity and cancer. However, the therapeutic potential of inhibiting the IL-21-BATF ... -
Liposome division by a simple bacterial division machinery.
(Proceedings of the National Academy of Sciences of the United States of America, 2013-07)We previously reconstituted Z rings in tubular multilamellar liposomes with FtsZ-YFP-mts, where mts is a membrane-targeting amphiphilic helix. These reconstituted Z rings generated a constriction force but did not divide ... -
Multiple endocytic pathways of G protein-coupled receptors delineated by GIT1 sensitivity.
(Proc Natl Acad Sci U S A, 2000-02-01)Recently, we identified a GTPase-activating protein for the ADP ribosylation factor family of small GTP-binding proteins that we call GIT1. This protein initially was identified as an interacting partner for the G protein-coupled ... -
Neutralizing BAFF/APRIL with atacicept prevents early DSA formation and AMR development in T cell depletion induced nonhuman primate AMR model.
(Am J Transplant, 2015-03)Depletional strategies directed toward achieving tolerance induction in organ transplantation have been associated with an increased incidence and risk of antibody-mediated rejection (AMR) and graft injury. Our clinical ... -
Nuclear import of Cdk/cyclin complexes: identification of distinct mechanisms for import of Cdk2/cyclin E and Cdc2/cyclin B1.
(J Cell Biol, 1999-01-25)Reversible phosphorylation of nuclear proteins is required for both DNA replication and entry into mitosis. Consequently, most cyclin-dependent kinase (Cdk)/cyclin complexes are localized to the nucleus when active. Although ... -
Platelet-derived growth factor receptor association with Na(+)/H(+) exchanger regulatory factor potentiates receptor activity.
(Mol Cell Biol, 2000-11)Platelet-derived growth factor (PDGF) is a potent mitogen for many cell types. The PDGF receptor (PDGFR) is a receptor tyrosine kinase that mediates the mitogenic effects of PDGF by binding to and/or phosphorylating a variety ... -
Receptor and G betagamma isoform-specific interactions with G protein-coupled receptor kinases.
(Proc Natl Acad Sci U S A, 1997-03-18)The G protein-coupled receptor (GPCR) kinases (GRKs) phosphorylate and desensitize agonist-occupied GPCRs. GRK2-mediated receptor phosphorylation is preceded by the agonist-dependent membrane association of this enzyme. ... -
Role of iPLA(2) in the regulation of Src trafficking and microglia chemotaxis.
(Traffic (Copenhagen, Denmark), 2011-07)Microglia are immune effector cells in the central nervous system (CNS) and their activation, migration and proliferation play crucial roles in brain injuries and diseases. We examined the role of intracellular ... -
Structural basis for receptor subtype-specific regulation revealed by a chimeric beta 3/beta 2-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1993-04-15)The physiological significance of multiple G-protein-coupled receptor subtypes, such as the beta-adrenergic receptors (beta ARs), remains obscure, since in many cases several subtypes activate the same effector and utilize ... -
Targeting Gbeta gamma signaling in arterial vascular smooth muscle proliferation: a novel strategy to limit restenosis.
(Proc Natl Acad Sci U S A, 1999-03-30)Restenosis continues to be a major problem limiting the effectiveness of revascularization procedures. To date, the roles of heterotrimeric G proteins in the triggering of pathological vascular smooth muscle (VSM) ... -
The evolving capabilities of rhodopsin-based genetically encoded voltage indicators.
(Curr Opin Chem Biol, 2015-08)Protein engineering over the past four years has made rhodopsin-based genetically encoded voltage indicators a leading candidate to achieve the task of reporting action potentials from a population of genetically targeted ... -
TRPV channel-mediated calcium transients in nociceptor neurons are dispensable for avoidance behaviour.
(Nat Commun, 2014-09-02)Animals need to sense and react to potentially dangerous environments. TRP ion channels participate in nociception, presumably via Ca(2+) influx, in most animal species. However, the relationship between ion permeation and ... -
Utility of telomerase-pot1 fusion protein in vascular tissue engineering.
(Cell Transplant, 2010)While advances in regenerative medicine and vascular tissue engineering have been substantial in recent years, important stumbling blocks remain. In particular, the limited life span of differentiated cells that are harvested ...
