Autor: Serge Mazères, Françoise Bachelerie, Bernard Lagane, André Lopez, Fernando Arenzana-Seisdedos, Gérald Gaibelet, Thierry Planchenault, Fabrice Dumas

Publikováno v: Journal of Biological Chemistry. 281:37921-37929

Human immunodeficiency virus entry into target cells requires sequential interactions of the viral glycoprotein envelope gp120 with CD4 and chemokine receptors CCR5 or CXCR4. CD4 interaction with the chemokine receptor is suggested to play a critical

CC chemokine receptor 5 (CCR5) is a G protein-coupled receptor that governs migration of leukocytes and serves as a coreceptor for the R5 tropic strains of human immunodeficiency virus (HIV). CCR5-mediated signaling in response to CC chemokines relie

Astroglial permissivity for neuritic outgrowth in neuron-astrocyte cocultures depends on regulation of laminin bioavailability

Autor: Thierry Lefrançois, Marcienne Tardy, C. Fages, Sharon L. Juliano, Yann Mouchel, Georgia Barlovatz-Meimon, Silvia Lima Costa, Thierry Planchenault, Cecile Charriere-Bertrand

Publikováno v: Glia. 37:105-113

The molecular determinants underlying the failure of axons to regenerate in the CNS after injury were studied in an in vitro model of astrogliosis and neuronal coculture. Mechanically lesioned neuron-astrocyte mouse cortical cocultures were treated w

Palmitoylation-dependent Control of Degradation, Life Span, and Membrane Expression of the CCR5 Receptor

Autor: Françoise Bachelerie, Yann Percherancier, Agustín Valenzuela-Fernández, Jean-Louis Virelizier, Fernando Arenzana-Seisdedos, Thierry Planchenault

Publikováno v: Journal of Biological Chemistry. 276:31936-31944

We have shown that the chemokine and HIV receptor CCR5 is palmitoylated on a cluster of cysteine residues located at the boundary between the seventh transmembrane region and the cytoplasmic tail. Single or combined substitutions of the three cystein

Latent fibronectin-degrading serine proteinase activity in N-terminal heparin-binding domain of human plasma fibronectin

Autor: Istvan Emod, Friedrich Lottspeich, V. Keil-Dlouha, Thierry Planchenault, Smilja Lambert Vidmar

Publikováno v: European Journal of Biochemistry. 201:71-77

The N-terminal 70-kDa fragment of human plasma fibronectin, purified from a cathepsin D digest, is characterized by lack of stability. It is processed proteolytically during incubation in the presence of Ca2+ into 27-kDa N-terminal heparin-binding an

WHIM (warts, hypogammaglobulinemia, infections, and myelokathexis) syndrome is an immune deficiency linked in many cases to heterozygous mutations causing truncations in the cytoplasmic tail of CXC chemokine receptor 4 (CXCR4). Leukocytes expressing

Potential Proteolytic Activity of Human Plasma Fibronectin: Fibronectin Gelatinase

Autor: J.-M. Imhoff, Istvan Emod, Xavier Blondeau, V. Keil-Dlouhá, Smilja Lambert Vidmar, Friedrich Lottspeich, Thierry Planchenault

Publikováno v: Biological Chemistry Hoppe-Seyler. 371:117-128

Human plasma fibronectin contains a latent proteinase that after activation cleaves gelatin and fibronectin. The autoactivation propensity of the two purified cathepsin D-produced fragments of fibronectin (190 and 120 kDa) was compared. Both polypept

Potential Proteolytic Activity of Fibronectin: Fibronectin Laminase and its Substrate Specificity

Autor: Istvan Emod, Lambert Vidmar S, Lafaye P, Thierry Planchenault, Keil-Dlouha, J.-M. Imhoff

Publikováno v: Biological Chemistry Hoppe-Seyler. 371:129-136

The purified 190-kDa fibronectin fragment produced by cathepsin D can be spontaneously activated in the presence of CaCl2. This activation generates new proteolytic activities and also results in the formation of several subfragments. One of them exh
