Which receptors are affected by caffeine ?4 answersCaffeine affects adenosine receptors (ADORs) and ryanodine receptors (RYRs) in the brain. It acts as an antagonist of ADORs, particularly ADORA1, ADORA2B, and ADORA3, and reduces the inhibitory effect of inflammation on ADORA1 in the mediobasal hypothalamus (MBH). Caffeine also decreases the stimulatory effect of endotoxin treatment on ADORA2B in the MBH and choroid plexus (ChP). In terms of RYRs, the expression of these receptors is less sensitive to the effects of inflammation and caffeine. Additionally, caffeine has an impact on NMDA receptor (NMDAR) activity in the hippocampus, likely mediated by blockade of inhibitory A1Rs and involvement of A2ARs. Caffeine also increases the metabolic competence of synapses, potentially through increased glycolytic rate and astrocyte-synapse lactate shuttling. Furthermore, caffeine's ergogenic effects are mediated by antagonism of A2ARs in forebrain neurons.

How does the RAS gene contribute to the development of preeclampsia?
5 answers
The renin-angiotensin system (RAS) plays a crucial role in the pathogenesis of preeclampsia (PE). Dysregulation of the RAS gene components, such as angiotensin-converting enzyme (ACE) and angiotensin II (Ang II), contributes to the development of PE. Genetic variations in the ACE gene, like the rs4343 polymorphism, have been associated with an increased risk of PE. Additionally, the overactivation of the Ang II/ACE/AT1R axis, along with decreased levels of protective components like ACE 2/Ang 1–7/MasR, can lead to hypertension characteristic of PE.
