The present invention provides methods inhibiting formation of neurofibrillary tangles; and methods for treating disorders relating to apolipoprotein E (apoE) in a subject. The methods generally involve reducing the level of a carboxyl-terminal truncated form of apoE in a neuronal cell of a subject. The invention further provides isolated cells comprising a nucleic acid molecule encoding a carboxyl-terminal truncated form of apoE; and methods of screening compounds using the cells. The invention further provides compounds that inhibit an apoE cleavage enzyme, and that reduce the formation of neurofibrillary tangles in a neuronal cell. The invention further provides transgenic non-human animals that include as a transgene a nucleic acid that encodes a carboxyl-terminal truncated form of apoE; as well as methods of screening compounds using transgenic animals.

La présente invention concerne des procédés permettant d'inhiber la formation d'enchevêtrements de neurofibrilles et des procédés de traitement des maladies associées à l'apolipoprotéine E (apoE) chez un individu. Les procédés consistent en général à réduire le taux d'une forme d'apoE tronquée au niveau du C-terminal dans une cellule neuronale d'un individu. La présente invention concerne également des cellules isolées qui comprennent une molécule d'acide nucléique codant une forme d'apoE tronquée au niveau du C-terminal et des procédés de criblage de composés effectués à l'aide de ces cellules; des composés qui inhibent l'enzyme de clivage apoE et qui réduisent la formation d'enchevêtrements de neurofibrilles dans une cellule neuronale; des animaux transgéniques non humains qui comprennent en tant que transgène, un acide nucléique codant une forme d'apoE tronquée au niveau du C-terminal ainsi que des procédés de criblage de composés effectués à l'aide de ces mêmes animaux transgéniques.
