Abstract

L'invention concerne des protéines d'immunoglobuline de fusion (fIg) comprenant un ou plusieurs épitopes hétérologues associés à des maladies pour lesquelles la réponse immunitaire est négative, lesdites protéines étant utiles pour induire une tolérance auxdits épitopes. Les épitopes gp120 du HIV-1 associés à l'intérieur d'un cadre à une chaîne lourde (H) d'Ig sont des produits de synthèse utiles pour induire une tolérance au HIV, spécifique aux épitopes. Le traitement d'un sujet avec ce type de produit de synthèse, ou bien avec des cellules lymphoïdes ou hématopoïétiques exprimant ou sécrétant ces molécules fIg, induit une tolérance immunologique spécifique aux épitopes considérés. En empêchant la production d'anticorps dirigés contre les épitopes gp120 déterminés, cette tolérance peut prévenir ou inhiber l'apoptose de "voisinage" sur les cellules T hôtes non infectées ayant effectué une liaison, à leurs molécules CD4 de surface, avec la protéine gp 120 du HIV et subissant ensuite une réticulation sous l'effet d'anticorps parasites anti-gp120. Cela donne pour les cellules T en question une amorce à l'apoptose, en présence des antigènes qui les activent. On utilise de préférence les épitopes gp120 correspondant à des épitopes de lymphocites B non neutralisants ou certains épitopes de lymphocytes T auxiliaires pour élaborer les molécules fIg. Outre les chaînes H de fIg et les molécules d'Ig complètes, l'invention concerne l'ADN codant les chaînes H en question et les cellules transformées par ce type d'ADN.
