Striatal efferents

In addition to presynaptic receptors, autoradiographic studies have indicated the presence of postsynaptic H3-receptor binding sites as well. Chemical destruction of postsynaptic structures in the striatum using quinolinic and kainic acid resulted in a marked decrease of striatal H3-receptor binding sites (Cumming et al., 1991 Pollard et al., 1993 Ryu et al., 1994). Consequently, a major part of the striatal H3-receptors may be located on striatal GABA neurons, representing more than 85% of the striatal efferents (Kita Kitai, 1988). [Pg.136]

In animal models of HD, transplanted striatal cells have survived, grow n and established afferent and efferent connections (Freeman et al., 2000). One open label human trial indicated that grafts may have restored function (Hauser et al., 2002). Recipients show ed cognitive and motor improvements thatw ere associated wdth reductions in striatal and cortical hypometaboiism. The success of grafting may be sensitive to the age of the donor and to the degree of neuronal loss in the patient. Clinical trials are in early phases and there still needs to be resolution of a number of technical issues (Gardian and Vecsei, 2004). [Pg.578]
