Terminal alpha (1,3) galactosyl galactoside epitopes (alpha-gal) on membrane glycoproteins expressed by vascular endothelial cells represent the major xenoreactive antigens in pig to primate xenotransplantation. In other discordant xenotransplantation combinations, such as from guinea pig to rat,
To better understand the pathophysiological role of Src protein, a non-receptor protein tyrosine kinase of 60kDa, in the ischemic brain, we investigated the time course and regional distribution of active Src expression by using a specific antibody against Tyr416 phosphorylated Src (phospho-Src) in
To explore new therapeutic strategies for Parkinson's disease, we studied the possible protective effect of an immunosuppressant, cyclosporin A (CsA), treatment on changes in dopaminergic function in rats with intrastriatal injections of 6-hydroxydopamine (6-OHDA). Four weeks after injection of
Ret receptor tyrosine kinase is the signaling component of the receptor complex for the family ligands of the glial cell line-derived neurotrophic factor (GDNF). Ret is involved in the development of enteric nervous system, of sympathetic, parasympathetic, motor and sensory neurons, and it is
Equine grass sickness (EGS) is a primary dysautonomia characterised pathologically by lesions in autonomic ganglia, enteric plexi and specific nuclei in the CNS. Immunocytochemistry and lectin histochemistry of the autonomic ganglia were used to determine whether abnormalities can be detected in
Amputation of a sensory peripheral nerve induces severe anatomical and functional changes along the afferent pathway as well as perception alterations and neuropathic pain. In previous studies we showed that electrical stimulation applied to a transected infraorbital nerve protects the somatosensory
Sensory neuron development and differentiation is dependent on a family of growth factors known as neurotrophins. Neurotrophins modulate neuron development via trk tyrosine kinase receptor proteins trkA, trkB and trkC. To determine how elevated levels of a target-derived neurotrophin might affect
BACKGROUND
The galactose alpha(1-3)galactose (alpha-gal) epitope associated with membrane glycoproteins and glycolipids represents a major determinant recognized on porcine cells by human xenoreactive natural antibodies (XNA). Together, bound XNA and complement rapidly induce porcine aortic
The mouse is the most commonly used species for in vivo studies on angiogenesis related to tumor development. Yet, to the best of our knowledge, very few reports on the in vitro interaction of the angiogenic basic fibroblast growth factor (bFGF) with mouse endothelial cells are available. Three
BACKGROUND
Xenoreactive natural antibodies (XNAs) and complement mediate hyperacute rejection of discordant xenografts. Inhibition of complement alone results in some prolongation of graft survival, but delayed xenograft rejection still precludes long-term graft survival. In vitro data provide
BACKGROUND
Ligation of alpha-galactosyl epitopes on endothelial cells by naturally occurring human antibodies causes hyperacute rejection in porcine-to-human xenotransplantation. The alpha-galactosyl-specific lectin Bandeiraea simplicifolia isolectin B4 (IB4) has been reported to trigger endothelial
Sensitivity to the pungent vanilloid, capsaicin, defines a subpopulation of primary sensory neurons that are mainly polymodal nociceptors. The recently cloned vanilloid receptor subtype 1 (VR1) is activated by capsaicin and noxious heat. Using combined in situ hybridization and histochemical
We studied the microglial reaction in mice using the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced model for Parkinson's disease (PD). Microglial cells were identified by means of the Griffonia simplicifolia lectin (GSA-I-B4). Dopaminergic neurons were marked by tyrosine hydroxylase
