Dopamine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [373]) are commonly divided into D1-like (D1 and D5) D2-like (D2, D3 D4) families, where endogenous agonist is dopamine.

background: the vascular function of angiotensin ii-type-2 receptors in adults is controversial. we sought their location and function in mouse aortic rings at young and old mice. materials and methods: male c57bl mice (aged 4 and 14 months) were killed by co2. the descending thoracic aorta was cleaned and dissected into rings. aortic rings were mounted in krebs’ solution at 37 °c and then setu...

social anxiety disorder (sad) is the one of the most common anxiety disorders. despite its high prevalence, the disorder is still considerably undiagnosed and untreated. the disease places a massive burden on patient’s lives, affecting not only their social interactions but also their educational and professional activities, thereby constituting a severe disability. γ-aminobutyric acid (gaba) s...

background: γ-aminobutyric acid (gaba) is considered to be the predominant inhibitory neurotransmitter in mammalian central nervous systems (cns). there are two major classes of gaba receptors: gabaars and gababrs. the gabaa receptor is derived from various subunits such as alpha1-alpha 6, beta1-beta 3, gamma1-gamma 4, delta, epsilon, pi, and rho1-3. intensive research has been performed to un...

Synthetic cannabinoids (SC) are a heterogeneous group of substances with a high affinity for cannabinoid receptors. Unlike Δ9-tetrahydrocannabinol (THC), synthetic cannabinoids are incredibly potent, highly productive, have more affinity for the Cannabinoid receptor type 1 (CB1), and Cannabinoid receptor type 2 (CB2), and are designed to accelerate the effects of tetrahydrocannabinol. Also, the...

A bacterial infection that affects the periodontium in various ways is called periodontitis. Bacterial plaque triggers inflammatory response host, which damages host's tissue. In to microbial invasion, it now understood immune system uses a family of pattern-recognition receptors termed Toll-like as mechanism initiate an response. TLRs, or toll-like receptors, were first identified drosophila a...

The extracellular matrix (ECM) niche plays a critical role in determining cellular behavior during bone development including the differentiation and lineage allocation of skeletal progenitor cells to chondrocytes, osteoblasts, or marrow adipocytes. As major ECM component mineralized tissues, collagen has instructive as well structural roles is required for cell differentiation. Cells sense the...

Introduction: 17β-Estradiol is a neuroactive steroid and its pain modulatory role has been well studied previously. 17β-Estradiol modulates nociception by binding to its receptors and also by allosteric interaction with other membrane - bound receptors such as glutamate and GABAA receptors. Paragigantocellularis lateralis (LPGi) is also involved in pain modulation and perception, in addition...
