Modification upon aging of the density of presynaptic modulation systems in the...
Canas, Paula M.; Duarte, João M. N.; Rodrigues, Ricardo J.; Köfalvi, Attila; Cunha, Rodrigo A.Different presynaptic neuromodulation systems have been explored as possible targets to manage neurodegenerative diseases. However, most studies used young adult animals whereas neurodegenerative diseases are prevalent in the elderly. Thus, we now explored by Western blot analysis how the density of different presynaptic markers and receptors changes with aging in rat hippocampal synaptosomes (purified nerve te...
Increase of cannabinoid CB1 receptor density in the hippocampus of streptozotoc...
Duarte, João M. N.; Nogueira, Célia; Mackie, Ken; Oliveira, Catarina R.; Cunha, Rodrigo A.; Köfalvi, AttilaIn the hippocampus, impaired neurophysiology, compromised neurogenesis, and eventually apoptosis accompany cognitive deficits in insulinopenic (type-1) diabetes (T1D). The underlying pathological mechanisms remain to be defined. The hippocampus has a high density of the cannabinoid type 1 receptor (CB1R), which has been shown to control several brain functions affected by diabetes, such as synaptic plasticity, ...
