Synaptophysin in human breast carcinomas
Histopathology, 1991 Synaptophysin expression was studied immunohisto‐chemically in 109 female and in three male breast carcinomas. Positivity was demonstrated in 10 female and in two male tumours in a high percentage of neoplastic cells. Synaptophysin positive breast carcinomas also expressed other neuroendocrine markers such as chromogranin and neuron‐specific enolase.

Synaptophysin immunoreactivity in the mammalian endocrine pancreas
Cell and Tissue Research, 1991Synaptophysin, a major membrane glycoprotein of small presynaptic vesicles in neurons, has also been found in microvesicles of endocrine cells, e.g., of the endocrine pancreas. In the present study, the endocrine pancreas in 9 mammalian species (man, dog, mink, bovine, rabbit, guinea pig, rat, mouse, gerbil) has been investigated immunohistochemically ...

SYNAPTOPHYSIN – AN IMMUNO-HISTOCHEMICAL MARKER FOR CHILDHOOD NEUROBLASTOMA
Apmis, 1987Synaptophysin, an integral membrane glycoprotein of presynaptic vesicles, was tested as an immuno‐histochemical marker for childhood neuroblastoma. Synaptophysin immuno‐reactivity was found in all neuroblastomas (6/6), but not in the other small round‐cell tumors to be considered in its differential diagnosis.

Synaptophysin sustains presynaptic performance by preserving vesicular synaptobrevin-II levels [PDF]
Journal of Neurochemistry, 2019 The two most abundant molecules on synaptic vesicles (SVs) are synaptophysin and synaptobrevin‐II (sybII). SybII is essential for SV fusion, whereas synaptophysin is proposed to control the trafficking of sybII after SV fusion and its retrieval during ...

Synaptophysin in the developing cochlea
International Journal of Developmental Neuroscience, 1988AbstractThe immunoreactivity to SY38 (anti‐synaptophysin antibody) was investigated in rat and guinea‐pig cochleas during development. In rat pups SY38 reactivity first appeared in the inner spiral bundle (below inner hair cells) at postnatal day 3. Later on (days 10 and 15) the basal pole of outer hair cells (OHCs) was also reactive.

The American Journal of Surgical Pathology, 1987
Synaptophysin (SYP) is a glycoprotein recently isolated from presynaptic vesicles of bovine neurons. Initial studies have demonstrated its presence in neurons in the brain, spinal cord and retina, and in adrenal medullary cells. A subsequent study demonstrated it in pancreatic islet cells and certain neuroendocrine (NE) neoplasms, including several ...

Synaptophysin immunohistochemistry in the human cochlea
Hearing Research, 2003Light microscopy and immunohistochemical analyses of a freshly prepared human cochlea, removed at meningioma skull base surgery, were performed with particular emphasis on synaptophysin (SY) reactivity. Synaptophysin, a 38-kDa glycoprotein, is one of the most abundant integral membrane proteins of small presynaptic vesicles and is a useful marker for ...

Synaptophysin: A reliable marker for medulloblastomas
Virchows Archiv A Pathological Anatomy and Histopathology, 1987Synaptophysin is an acidic, integral membrane glycoprotein (Mr 38,000) of presynaptic vesicles in various neurons and neuroendocrine cells, and in tumours derived from such cells. By indirect immunofluorescence microscopy of cryostat sections, using the monoclonal antibody SY 38 to synaptophysin, a consistent positive immunoreactivity was observed in ...

Synaptophysin is an autoantigen in paraneoplastic neuropathy
Journal of Neuroimmunology, 2008Paraneoplastic neurological syndromes (PNS) are often associated with antineuronal autoantibodies and many of them could be identified in the recent years. However, there are still new antineuronal binding patterns with yet unidentified autoantigens.
