Control of GABA neurotransmission at the pre-synaptic site occurs substantially through the activation of the glutamic acid decarboxylase (GAD) enzymes GAD65 and GAD67. Concentrations of GAD65 and GAD67 are controlled either by transcription or by mRNA splicing and importantly the activities of these key enzymes are regulated by post-translational mechanisms. Important post-translational modifications include prote Read More

Gamma-amino butyric acid (GABA), the major inhibitory neurotransmitter in the mammalian central nervous system, plays a key role in the regulation of neuronal transmission throughout the brain, affecting numerous physiological and psychological processes. Changes in GABA levels provoke disbalance between excitatory and inhibitory signals, and are involved in the development of numerous neuropsychiatric disord Read More

Alzheimer’s disease (AD) is the most common form of dementia in the elderly. Research focused on identifying compounds that restore cognition and memory in AD patients is a very active investigational pursuit, but unfortunately, it has been only successful in terms of developing symptomatic treatments. Aβ deposition and neurofibrillary tangles along with neuron and synapse loss are associated with neurotransmi Read More

Fragile X spectrum disorder (FXSD) includes: fragile X syndrome (FXS), fragile X-associated tremor ataxia syndrome (FXTAS) and fragile X-associated primary ovarian insufficiency (FXPOI), as well as other medical, psychiatric and neurobehavioral problems associated with the premutation and gray zone alleles. FXS is the most common monogenetic cause of autism (ASD) and intellectual disability (ID). The und Read More

Central nervous system is not spared from the deleterious effects of diabetes, since several studies have described neuropsychological and neurobehavioral changes in diabetic subjects, suggesting that diabetic encephalopathy should be recognized as a complication of this complex metabolic disorder. In fact, psychiatric manifestations may accompany this encephalopathy, since the prevalence of depression in diabe Read More

Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the central nervous system, and diseases that associate a deficiency in GABA might benefit from GABAergic drugs. Cerebellar Purkinje cells employ GABA as a neurotransmitter. Cortical cerebellar atrophy (CCA) shows Purkinje cell loss, and ataxia caused by it was alleviated by gabapentin and pregabalin. Thus, CCA is proposed as a model of selective de Read More

Since the first report about the presence of γ-aminobutyric acid (GABA) within the gastrointestinal (GI) tract, accumulating evidence strongly supports the widespread representation of the GABAergic system in the enteric milieu, underlining its potential multifunctional role in the regulation of GI functions in health and disease. GABA and GABA receptors are widely distributed throughout the GI tract, constituting a complex n Read More

Genome-wide studies have identified thousands of noncoding RNAs (ncRNAs) with no protein coding capacity. Among them, the long non-coding RNAs (lncRNAs), which are more than 200 nucleotides in length, recently are widely concerned for their crucial role in regulating biological processes and diseases. However, most lncRNAs are expressed at a very low level, and generally exhibit poor primary sequence conser Read More

Bone cancer pain (BCP) is still an intractable problem currently because the analgesic pharmacological intervention remains insufficient. Thus, the development of novel therapeutic target is critical for the treatment of BCP. Emerging evidence demonstrated that some chemokines and their receptors contribute to the induction and maintenance of BCP. In this article, we reviewed the current evidence for the role of different Read More

Coffee is among the most widespread and healthiest beverages in the world. It is known to be a highly rich source of biologically active natural metabolites which possess therapeutic effects (i.e. caffeine) and functional properties (i.e. chlorogenic acids). Therefore, coffee can be considered a drink which has different positive effects on human health such as cardioprotective, neuroprotective, hepatoprotective, nephroprotecti Read More

Background: Clopidogrel’s ability to inhibit platelet function determined its clinical usefulness. The role of CYP2C19*2 genotype on antiplatelet treatment is recently under question. Arterial wall properties and inflammation are key players in atherosclerosis development. Hence, we evaluated the impact of CYP2C19*2 genetic polymorphism on endothelial function, arterial stiffness and inflammation in coronary artery Read More
