Does the fatty acid DHA modulates the dopamine receptor 2 (DR2)?
Best insight from top research papers
DHA has been shown to modulate the oligomerization of dopamine receptor 2 (DR2) . However, a study found that D2-like receptor initiated signaling does not involve DHA as a second messenger . Another study demonstrated that DHA regulates dopamine D2 receptor functions through heart-type fatty acid binding protein (H-FABP) in the brain . Additionally, a diet-induced loss of brain DHA content was found to decrease the density of ventral striatal D2-like receptors . Therefore, while DHA may have an effect on DR2 through its role in receptor oligomerization and H-FABP-mediated regulation, it does not appear to directly modulate DR2 signaling as a second messenger.

What are the effects of omega-3 fatty acid supplementation on dopamine levels in the human brain?4 answersOmega-3 fatty acid supplementation has been shown to have effects on dopamine levels in the human brain. Studies have demonstrated that omega-3 fatty acids, particularly docosahexaenoic acid (DHA), play a role in the modulation of dopamine transmission and dopamine receptor activity. Membrane enrichment in DHA has been found to enhance ligand binding to the dopamine D2 receptor (D2R), suggesting that DHA acts as an allosteric modulator of this receptor. In addition, omega-3 fatty acid deficiency has been associated with lower levels of DHA in the brain, which can lead to impaired dopaminergic function. Clinical studies have also shown that omega-3 fatty acid supplementation can improve symptoms and cognitive function in patients with schizophrenia, a disorder involving dysregulation of the brain dopamine systems. These findings suggest that omega-3 fatty acid supplementation may have a positive impact on dopamine levels and dopaminergic function in the human brain.
Does DHA improves memory or cognitive response ?4 answersDHA supplementation has been shown to improve cognitive function and memory in various populations. A study conducted on older adults with memory complaints found that a combination of DHA-rich fish oil and cocoa flavanols did not improve cognitive outcomes, except for reaction time variability, alertness, and executive function, which showed a decline in function in the intervention group. Another study on Thai children aged 6-12 years old found that high dose DHA supplementation improved attention and cognitive processing ability, as measured by changes in brain activity during cognitive tasks. In a study on female APOE4 carriers, DHA-enriched fish oil supplementation improved recognition memory and increased brain DHA levels, providing protection against cognitive deficits associated with menopause and APOE4. Additionally, DHA supplementation has been shown to improve learning and memory function, reduce neuronal damage, and inhibit the deposition of amyloid-beta plaques and tau protein neurofibrillary tangles in mice. Finally, a study on older women found that a high-DHA multi-nutrient supplement improved verbal memory and executive function, suggesting that supplementation may mitigate the effects of low physical activity on cognitive function in the elderly.
How does DHA affect the development of infants?3 answersDHA, or docosahexaenoic acid, is an important component for brain development in infants. Studies have shown that DHA supplementation during pregnancy and lactation can have positive effects on cognitive skills and language development in children. However, the effects of DHA on neurodevelopment may vary and are influenced by factors such as maternal intake and status, as well as genetic factors. While some studies have reported improved language scores in children receiving DHA supplementation, others have found no significant effects. It is important to note that the long-term effects of DHA inadequacy during fetal development are still not fully understood. Overall, DHA intake, particularly during the last trimester of pregnancy and early infancy, may contribute to optimal conditions for brain development in infants.
Does the fatty acid DHA modulate the activity of dopamin receptor 2 (DR2)?5 answersDHA, a fatty acid, has been shown to modulate the activity of dopamine receptor 2 (DR2) ^[Davis] ^[Guixà-González]. In a study using computer modeling and bioluminescence resonance energy transfer (BRET) experiments, it was found that DHA increased the rate of oligomerization of adenosine A2A and dopamine D2 receptors, which are G protein-coupled receptors (GPCRs) ^[Guixà-González]. Another study demonstrated that DHA suppressed NFκB activation induced by the agonist for TLR2, which is a receptor that does not require acylated fatty acids, suggesting that DHA can modulate the activation of TLRs ^[Lee]. Additionally, a study on the effects of decreased brain DHA levels in rats found alterations in dopaminergic parameters, including a decreased density of ventral striatal D2-like receptors, which is consistent with the hypodopaminergic basis for depression ^[Davis]. Therefore, the evidence suggests that DHA can modulate the activity of DR2.
Why are EPA and DHA important for the food web?5 answersEPA and DHA are important for the food web because they have been shown to have beneficial effects on cardiovascular health and calcium absorption. Studies have demonstrated that high-dose purified EPA can reduce atherosclerotic cardiovascular disease-related events and cardiovascular mortality. Additionally, EPA and DHA have been found to enhance calcium absorption, which can help attenuate obesity and increase mobility. These omega-3 fatty acids also play a role in the production of downstream metabolites that promote the resolution of inflammation. While the threshold for clinical benefit of EPA has been suggested to be approximately 100 μg/mL, more research is needed to establish a similar threshold for DHA. Overall, EPA and DHA have demonstrated their importance in maintaining cardiovascular health and promoting calcium absorption, making them essential components of the food web.
How is Bax/Bcl-2 impacted by n-3 PUFAs or DHAs?5 answersBax and Bcl-2 proteins are impacted by n-3 PUFAs or DHAs. In the study by Klimentova et al., they found that in arterial walls with hyperechoic (calcified) atherosclerotic plaques (APs), the expression of anti-apoptotic protein Bcl-2 was reduced, and that of pro-apoptotic protein Bax was increased, indicating apoptosis activation in advanced atherosclerotic lesions. In the study by Dlugosz et al., they showed that Bcl-2 inhibits apoptosis by regulating the release of cytochrome c from mitochondria, while oligomerization of Bax promotes cell death by permeabilizing the outer mitochondrial membrane. These findings suggest that the balance between Bax and Bcl-2 proteins is important in regulating apoptosis. However, none of the abstracts specifically mention the impact of n-3 PUFAs or DHAs on Bax/Bcl-2. Further research is needed to determine the effects of n-3 PUFAs or DHAs on Bax/Bcl-2 expression and apoptosis regulation.
