there is interrelationship between the immune and nervous systems that is accomplished by the molecular mediators. dopamine is one of the most important neurotransmitters. five different dopamine receptor genes (drd1, drd2, drd3, drd4, and drd5) have been recognized and cloned. the expression of the dopamine receptors is well characterized in the brain but little work has been done to examine t...

Background: Feeding behavior is regulated by a complex network which interacts via diverse signals from central and peripheral tissues. It is known dopaminergic and glutamatergic systems have crucial role on food intake regulation but scarce reports exist on their interaction in appetite regulation in broilers. OBJECTIVES: The present study was designed to examine the role of glutamatergic syst...

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.

In severe COVID-19 patients the blood level of autoantibodies (IgG) to neurospecific proteins was determined. It defined marked increase in peripheral myelin protein, protein lipid S100 type 2 dopamine receptors and dopamine. At same time, it designate relationship between levels NMDA receptors. High specific IgG SARS-CoV-2 S-Trimer Protein coincided with high

BACKGROUND: Brain monoamines (such as histamine and dopamine) play an important role in emotions, cognition, reward and feeding behavior. The interactions between histamine and dopamine were studied in many physiological functions but this correlation is unclear in feeding behavior of chickens. The aim of this study was to investigate the interaction of central histaminergic and dopaminergic sy...

On most adrenergic and cholinergic nerve terminals, prejunctional α-adrenoceptors belonging to the α2-subtype have been identified. Activation of these receptors will decrease the release of norepinephrine. It has been reported that several isolated tissue preparations contain prejunctional dopamine receptors, the stimulation of which inhibits neurotransmission. It has remained uncertain whethe...

Introduction: The hippocampus (HIP), the primary brain structure related to learning and memory, receives sparse but comprehensive dopamine innervations and contains dopamine D1/D2-like receptors. It is demonstrated that dopamine receptors in dentate gyrus (DG) region of HIP have a remarkable function in spatial reward processing. Much less is known about the involvement of HIP and its D1...

objectives the cause of rheumatoid arthritis (ra) as a chronic inflammatory autoimmune disease is still unknown. it appears that both genetic and environmental factors play a role in its pathogenesis. recent studies reveal that in addition to the cns, immune cells synthesis neurotransmitters so that these catecholamines can regulate immune functions. the aim of this study is to evaluate the dop...
