Pearse's 'APUD” cell theory helps define the ontogeny and differentiation programs of small
polypeptide hormone-secreting cells of diverse tissue origins. Cells with such features may …

In an attempt to reveal the function sites of substance P (SP) in the central nervous system
(CNS), the distribution of SP receptor (SPR) was immunocytochemically investigated in adult …

The dorsal horn of the spinal cord is a primary receiving area for somatosensory input and
contains high concentrations of a large variety of receptors. These receptors tend to …

The original proposal that substance P is involved in the regulation of nociceptive
information at the first sensory synapse in the spinal cord has been substantiated by a wide …

A comparison of anatomical distributions of substance P (SP) and substance P receptors in
the rat central nervous system was performed. SP was localized by microdissection and …

Oxytocin-binding sites were detected by autoradiography on rat brain sections incubated in
the presence of the [3 H] oxytocin. These sites were characterized pharmacologically using …

Light microscopic studies have demonstrated significant mismatches in the location of
neuropeptides and their respective binding sites in the central nervous system. In the …

The undecapeptide substance P (SP) was tested for its ability to promote human monocyte
chemotaxis in a modified Boyden chamber assay. Substance P was found to be active in this …
