Disclosed is a method for inhibiting Ras-induced or mediated proliferation of cells associated with a non-malignant disease, disorder or pathological condition. The method entails administering to a patient a Ras antagonist in an amount effective to inhibit the proliferation. The invention is particularly applicable to diseases characterized by a proliferation of T- cells such as autoimmune disease, e.g., type 1 diabetes, lupus and multiple sclerosis, and pathological states such as graft rejection induced by the presentation of a foreign antigen such as a graft in response to a disease condition (e.g., kidney failure). Other non-malignant diseases characterized by proliferations of cells include cirrhosis of the liver and restenosis. Preferred Ras antagonists are S-trans- trans farnesylthiosalicylic acid (FTS) and structurally related compounds (or analogs) thereof.

L'invention concerne une méthode permettant d'inhiber la prolifération cellulaire induite ou régulée par Ras, associée à une maladie, à un trouble ou à un état pathologique non malins. Cette méthode consiste à administrer à un patient un antagoniste de Ras en quantité suffisante pour inhiber la prolifération. Cette méthode convient en particulier pour les maladies qui se caractérisent par une prolifération de lymphocytes T, telles que les maladies auto-immunes, par exemple le diabète de type I, le lupus et la sclérose en plaques, ainsi que pour des états pathologiques tels que les rejets de greffe induits par la présentation d'un antigène étranger dans le cas d'une greffe réalisée suite à un état pathologique (p. ex. insuffisance rénale). D'autres pathologies non malignes caractérisées par une prolifération cellulaire comprennent notamment la cirrhose du foie ou la resténose. Les antagonistes de Ras préférés sont l'acide S-trans-trans farnésylthiosalicylique (FTS) et des composés structurellement voisins (ou analogues) de ce dernier.
