Sorry if this is an inappropriate place to post, but I am looking for an 
e-mail address for Jean-Pierre de Villartay. 

 The only address I have is Laboratoire INSERM U132, Developpment Normal et 
Pathologique du Systeme Immunitaire, Hopital Necker-Enfants-Malades, 149 rue 
de Sevres,  Paris France

Any help would be appreciated
