The role of the brain in hypertension between the sexes is known to be important especially with regards to the effects of circulating sex hormones. A number of different brain regions important for regulation of sympathetic outflow and blood pressure express estrogen receptors (ERα and ERβ). Estradiol, acting predominantly via the ERα, inhibits angiotensin II activation of the area postrema and subfornical organ neurons and inhibits reactive oxygen generation that is required for the development of Angiotensin II-induced neurogenic hypertension. Estradiol activation of ERβ within the paraventricular nucleus and the rostral ventral lateral medulla inhibits these neurons and inhibits angiotensin II, or aldosterone induced increases in sympathetic outflow and hypertension. Understanding the cellular and molecular mechanisms underlying ERα and ERβ actions within key brain regions regulating blood pressure will be essential for the development of "next generation" selective estrogen receptor modulators (SERMS) that can be used clinically for the treatment of neurogenic hypertension.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 June 2014.
All research outputs
#18,373,874
of 22,757,541 outputs
Outputs from Current Hypertension Reports
#549
of 732 outputs
Outputs of similar age
#163,575
of 227,891 outputs
Outputs of similar age from Current Hypertension Reports
#7
of 14 outputs
Altmetric has tracked 22,757,541 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 732 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 8th percentile – i.e., 8% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 227,891 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
