This paper reviews the immunohistochemical characteristics of two kinds of human cutaneous sensory nerve formations (SNFs), the Meissner and Pacinian corpuscles. In both kinds of SNF the central axon might be easily identifiable because it displays immunoreactivity (IR) for the neuroendocrine markers neuron-specific enolase and protein gene product 9.5, as(More)
Pacinian corpuscles depend on either Aalpha or Abeta nerve fibers of the large- and intermediate-sized sensory neurons for the development and maintenance of the structural integrity. These neurons express TrkB and TrkC, two members of the family of signal transducing neurotrophin receptors, and mice lacking TrkB and TrkC lost specific neurons and the(More)
The occurrence and distribution of beta-amyloid precursor protein (beta APP) and of beta-amyloid peptide (beta/A4) was investigated using immunoblotting and immunohistochemical techniques in the digital skin of healthy adult subjects. beta APP-like proteic bands with apparent molecular masses between 55-60 kDa, 100-125 kDa (corresponding to the full-length(More)
The presence of nerve growth factor receptors (NGFr) in sensory nerve corpuscles of human digital skin, primarily Meissner and Pacinian corpuscles, was investigated immunohistochemically using two monoclonal antibodies directed against human-NGFr. To ensure the localization of NGFr immunoreactivity (IR) alternative sections to that processed for NGFr(More)
The distribution of several markers for Schwann cells and perineurial cells, including S-100 protein, Leu-7 antigen, vimentin and epithelial membrane antigen was studied immunohistochemically in Pacinian corpuscles from human digital skin. Formaldehyde fixed paraffin embedded tissues, and monoclonal antibodies were used. A positive immunostaining for S-100(More)
The denervation-induced changes on S-100 protein, glial fibrillary acidic protein (GFAP) and vimentin immunoreactivity (IR) of the lamellar cells from cutaneous Meissner-like sensory nerve formations (SNF), or corpuscles, of the adult rat hind limb foot-pads were studied, using combined immunohistochemical and image analysis (optic microdensitometry)(More)
The reinnervation of human glabrous skin autografts was investigated in biopsy specimens obtained four weeks to 15 months after transplantation. The grafted skin was taken from the volar aspect of the wrist and transplanted to the fingers. Immunohistochemical methods were used to detect the presence of nerve fibres and sensory corpuscles, using monoclonal(More)
The sensory nerve formations (or corpuscles) of normal human glabrous skin from hand and fingers, obtained by punch biopsies, were studied by the streptavidin-biotin method using monoclonal antibodies directed against neurofilament protein (NFP), S-100 protein, glial fibrillary acidic protein (GFAP), cytokeratins, and vimentin. NFP immunoreactivity (IR) was(More)
