THE distribution and neuronal or glial localization of GAT-1, a high affinity GABA transporter, in the cerebellar cortex was analysed by means of double-label immunofluorescence experiments with GAT-1 combined with calbindin D, synaptophysin, or GFAP antibodies. In the Purkinje cell (Pc) layer, prominent synaptic GAT-1-immunoreactivity (IR) was found in the(More)
Quantitative autoradiography (using [125I]human alpha-calcitonin gene-related peptide as a ligand) and immunofluorescence (using monoclonal antibodies directed against a purified receptor) followed by confocal analysis were applied to analyse the distribution and cellular localization of the calcitonin gene-related peptide receptor in the rat cerebellum(More)
Previous reports have described the transient expression of the neuropeptides calcitonin gene-related peptide and neuropeptide Y in selected subsets of rat olivocerebellar compartments during embryonic and postnatal development. Using these neuropeptides as endogenous markers for olivocerebellar fibers, the aim of this electron microscopic analysis was to(More)
Several studies have explored the impact of marital bereavement on mortality, while increasing emphasis has recently been placed on genetic factors influencing longevity - in this paper, we study the impact of losing the spouse and losing the co-twin, for twins aged 50 to 70. We use data from the Danish Twin Registry and the Population Register of Denmark(More)
GAS6, a gene previously identified as growth arrest specific, has been demonstrated to be the ligand of Axl, a novel tyrosine kinase receptor widely expressed in both normal and neoplastic hematopoietic tissue. We have observed previously that GAS6 mRNA was present in whole bone marrow. This preliminary finding prompted us to investigate the presence of(More)
Efferents from the cardiovascular portion of the fastigial nucleus (rFN), whose electrical stimulation has been found to elicit secretion of vasopressin in the rat, have been traced by use of the anterograde fluorescent tracer Fast blue (FB). In the same animal the retrograde marker Diamidino yellow (DY) was injected in the paraventricular nucleus of the(More)
In view of the key role exerted by neurotransmitter transporters in the synaptic transmission, the expression of GABA transporter GAT-1 was analysed during cerebellar development, when relevant processes of synapse maturation take place. GAT-1-immunoreactive (IR) structures started to be detected on PD 8-9, at the low molecular and Purkinje cell layer,(More)
Origin and percentage of bilaterally projecting pontocerebellar neurons whose axons branch within the cerebellum and link the two cerebellar hemispheres were studied in cats using double retrograde fluorescent tracing and lesion techniques. These pontocerebellar neurons, which can be viewed as a separate component of the pontocerebellar system, account for(More)
The cerebellum is organized in a series of parasagittal compartments: in C1-C3 and C2 compartments Purkinje cells receive climbing fibre afferents from the rostral part of the accessory olives, and project their axon to the nucleus interpositus anterior and posterior, respectively. Within these compartments electrophysiological studies have shown that the(More)
