Partially purified extracts from neuroblastoma× glioma hybrid cells 108CC15 inhibit, like
opioids, the prostaglandin E1‐evoked formation of cyclic AMP in a dose‐dependent manner …

Recent anatomical evidence indicates that the pontine A7 catecholamine cell group
provides the major noradrenergic innervation of the spinal cord dorsal horn (laminae I-IV) …

At least two classes of nociceptors can be distinguished based on their growth factor
requirements: glial cell-line derived neurotrophic factor (GDNF)-and nerve growth factor …

Opioid receptors expressed by peripheral pain-sensing neurons are functionally inactive for
antinociceptive signaling under most basal conditions; however, tissue damage or exposure …

The peptides substance P (SP), methionine-enkephalin (M-ENK), leucine-enkephalin (L-
ENK), and cholecystokinin (CCK) were released iontophoretically near spinothalamic tract …

Adrenal medullary chromaffin cells were transplanted to the midbrain periaqueductal gray, a
region known to play a primary role in the modulation of nociception. Chromaffin cells were …

Plasticity of dorsal root ganglion (DRG) nociceptors in the peripheral nervous system
requires new protein synthesis. This plasticity is believed to be responsible for the …

Pharmacological evidence for the existence of δ-opioid receptor subtypes has been
reported. This study was conducted to determine which type of δ-opioid receptors was …

Intrathecal implants of adrenal chromaffin cells are known to release analgesic substances
such as catecholamines and opioid peptides. In the present study, bovine chromaffin cells …

To test the hypothesis that the expression of specific proteins on peripheral terminals of
primary afferents can be attenuated by intrathecal administration of antisense …
