  • Transgenic animal whose expression of the opiate receptors is modified
    Patent number: 6632977
    Abstract: The invention concerns the use of a non-human transgenic mammal whose expression of a gene coding for an opiate receptor is modified, particularly in the nerve tissues with respect to a normal expression, in particular in the nerve tissues, for producing a medicine for the treatment of pathological conditions involving opiate receptors, in particular severe acute or chronic pains, drug addiction or the prevention or the treatment of transplant rejections.
