Histamine receptors in extra- and intracranial arteries
- 21 Downloads
Histamine contracts pial arteries in a nonspecific manner, whereas the contraction in extracranial arteries is mediated by H1 receptors. In both types of arteries histamine also produces dilation, mediated by H2 receptors.
The study was supported by the Swedish Medical Research Council (grant No. 14X-732).
