Biophysique cellulaire

Nous développons une approche multidisciplinaire combinant la biologie cellulaire et la biophysique pour déterminer les mécanismes des perturbations membranaires induites par les modifications du potentiel transmembranaire, c'est-à-dire par la technique d'électroporation ou d'électroperméabilisation.

Dans ce contexte, et sur la base de nos travaux antérieurs, les principaux objectifs que nous avons poursuivis sont :

•    L’élucidation des mécanismes d'électrotransfert : nos travaux mettent en évidence les différences entre le transfert de petites molécules (bléomycine, cis-platinium), de petits oligonucléotides (siRNA, LNA), de protéines et d'ADN plasmidique et entre les mécanismes impliqués in vitro sur cellules en culture (modèles bidimensionnels et tridimensionnels) et in vivo sur tissus (modèle murin).

•    Le développement de nouveaux outils de délivrance, de ciblage et de diagnostic : nos résultats nous ont conduit à définir de nouveaux types de générateurs d'impulsions électriques et d'électrodes (adaptés pour l'étude in vitro et in vivo) et à adapter les systèmes d'imagerie (chambre à fenêtre dorsale, micro et macroscopie à fluorescence). De plus, nous développons d'autres approches d'administration de médicaments non viraux basées sur la lectine et nous utilisons des aptamères d'ADN qui se lient spécifiquement aux cellules cancéreuses. Cette approche a des intérêts pour le ciblage des tumeurs (administration de médicaments) et le diagnostic (imagerie des tumeurs solides).

Valorisation

3rd Price of the 25th "concours innovation Midi-Pyrénées" , Section « laboratory and research teams » :

• J.TEISSIE, MP. ROLS, M. GOLZIO, Y. TAMZALI, B.COUDERC. Device for eradication of horses cutaneous tumors by electrochemo- and electrogenotherapy.

Application for Technology Transfer : « Fluorescence imaging device for small animals (whole body)» Date of the comity : 20 Avril 2006. N° AV ou N° St DI 00745-01

• The invention is a device which allows the study, by fluorescence imaging, of few centimeters objects. The inventive activity does not allow to apply for a patent : this is a combination of well-known elements that could be evident for an expert. However, this could be a skill, specially in micro biology.

• The "Comité des Engagements" gave a favorable verdict to Technology transfer via "Licence de Savoir-Faire".
