Glycosylation seems also to be involved in the targeting of brain regions by prions leading to strain-specific lesion profiles as previously suggested in a study using transgenic mice overexpressing hamster PrP mutated at the 2nd glycosylation site [12].
If so, neurons with a relatively large number of synapses can be a potent candidate for the target of lithium treatment in human brain.
Here, I discuss several factors that might influence the selective targeting of brain regions in different diseases, using familial PrDs as a model.
This probably accounts for the depressive side of withdrawal symptoms (serotonin receptors in the brain are the target of antidepressant drugs such as Prozac).
The basal ganglia also are the main target of deep brain stimulation for movement disorders and increasingly also for behavioural disorders, and a better understanding of their non-motor functions would be of great clinical importance.
These are important and promising features for the possibility to use these nanoliposomes for the targeting of Aβ in the brain districts.
The targets of loxapine in the brain are dopamine and serotonin-receptor subtypes [ 30], with few hemodynamic effects, explaining why we observed no significant changes in hemodynamic parameters after loxapine administration.
We also examined factors known to affect the utility of radioligands for brain imaging: blockade of entry into brain by efflux transporters at the blood brain barrier, the density of the target (mGluR1) in brain, the affinity of 11C-LY2428703 for mGluR1, and binding of the radioligand to plasma proteins.
In line with these considerations, the targeting of the vascular microenvironment in brain tumours to arrest tumour growth has been proposed to explain mechanisms associated to drugs with antiangiogenic potential (Calabrese et al, 2007).
Development of chronic epileptogenesis by a precise focal activation of the target brain site is readily achieved with no mortality and very little morbidity.
