AbstractOn December 9th and 10th, 1993, the GTRV (Groupe Thématique de Recherche sur les Vecteurs) held a successful symposium in Nancy (France). GTRV is a non profit-making French research association focusing on drug targeting. Based on a multidisciplinary approach, the GTRV rallies scientists both from Universities and well-known French public research organizations (CNRS and INSERM) as well as from the Pharmaceutical and Cosmetic industries. The GTRV is composed of more than 400 members, approximately 40% are from industry. Although most of GTRV members are French, it also includes scientists from other countries (Canada, Switzerland and EC countries).
