Dr. Juan Fernández
Grado:
Ph.D., University of Wisconsin, USA, 1968
Tema de investigación o interés:
• Rutas y mecanismos involucrados en el traslado y establecimiento de dominios citoplasmáticos en el zigoto y embrión temprano de la sanguijuela y del pez
Cebra.
Para este propósito se utilizan diferentes tipos de video microscopía digital, confocal y electrónica en combinación con inmunofluorescencia, hibridación in situ
y microinyección de sondas, drogas y anticuerpos.
• Reorganización del citoesqueleto de glándulas salivales labiales de pacientes con el síndrome de Sjögren (enfermedad auto inmune). Inmonofluorescencia y
bioquímica.
• Desarrollo de nuevas metodologías para la preparación de células y tejidos destinados a la inmunofluorescencia o hibridación in situ.
Research Interest:
• Pathways and mechanisms involved in the transport and establishment of cytoplasmic domains in the leech and zebrafish zygote and early embryo.
To this purpose different types of digital video microscopy, confocal and electron microscopy are utilized in combination with immunofluorescence, in situ
hybridization and microinjection of probes, drugs and antibodies.
• Reorganization of the cytoskeleton in the labial salivary glands of patients with the Sjögren syndrome (autoimmune disease). Immunofluorescence and
biochemistry.
• Development of new methodologies for the preparation of cells and tissues destined for immunofluorescence or in situ hybridization.
