REVIEW
Ya-Ru Gao, Yong-Qiang Wang
Endocannabinoid system is related with various physiological and cognitive processes including fertility, pregnancy, during pre- and postnatal development, pain-sensation, mood, appetite, and memory. In the latest decades, an important milestone concerning the endocannabinoid system was the discovery of the existence of the cannabinoid receptors CB1 and CB2. Anandamide was the first reported endogenous metabolite, which adjusted the release of some neurotransmitters through binding to the CB1 or CB2 receptors...

The liver has unique microenvironment which is known to induce tolerance of cytolytic CD8+ T cells to hepatic and extra hepatic antigens, resulting in persistence of infection of the liver by the hepatitis B and C viruses. However, under some conditions, functional immune responses can be elicited in the liver in particular to show preferential retention of activated CD8+ T cells. It is not clear whether this retention depends on the type of the exogenous immunostimulatory or the endogenous innate immune cells...

Metabolic disorders are closely associated with dietary habits and seem to be related to neuroinflammation and neurodegenerative disease in humans. Emblica officinalis (EOT) fruits not only have good nutritional value but also have excellent therapeutic potential. We used a tannins-enriched fraction of EOT fruit with the expectation of controlling diet-induced neuroinflammation and cognitive impairment in rats. A high-salt and cholesterol diet (HSCD) was used to induce neuroinflammation and cognitive impairment in rats...

OBJECTIVE: To quantitatively examine the regional densities and hemispheric distribution of the 43-kDa transactive response DNA-binding protein (TDP-43) inclusions, neurons, and activated microglia in a left-handed patient with right hemisphere language dominance and logopenic-variant primary progressive aphasia (PPA). METHODS: Phosphorylated TDP-43 inclusions, neurons, and activated microglia were visualized with immunohistochemical and histologic methods. Markers were quantified bilaterally with unbiased stereology in language- and memory-related cortical regions...

Background/Study Context: Older adults show lower memory performance than younger adults when a task requires them to create associations (Naveh-Benjamin, 2000, Journal of Experimental Psychology: Learning, Memory, and Cognition, 26, 1170-1187). In this study, associative memory was examined in order to assess whether age differences in performance were mitigated when the word pairs to be learned utilized a familiar pattern seen in everyday language (adjective-noun), which we propose as a type of schematic support that capitalizes upon linguistic structure...

Furin is a proprotein convertase implicated in a variety of pathological processes including neurodegenerative diseases. However, the role of furin in neuronal plasticity and learning and memory remains to be elucidated. Here, we report that in brain-specific furin transgenic (Furin-Tg) mice, the dendritic spine density and proliferation of neural progenitor cells were significantly increased. These mice exhibited enhanced long-term potentiation (LTP) and spatial learning and memory performance, without alterations of miniature excitatory/inhibitory postsynaptic currents...

An age-related associative deficit has been described in visual short-term binding memory tasks. However, separate studies have suggested that ageing disrupts relational binding (to associate distinct items or item and context) more than conjunctive binding (to integrate features within an object). The current study directly compared relational and conjunctive binding with a short-term memory task for object-colour associations in 30 young and 30 older adults. Participants studied a number of object-colour associations corresponding to their individual object span level in a relational task in which objects were associated to colour patches and a conjunctive task where colour was integrated into the object...

The neuronal RNA-binding protein HuD is involved in synaptic plasticity and learning and memory mechanisms. These effects are thought to be due to HuD-mediated stabilization and translation of target mRNAs associated with plasticity. To investigate the potential role of HuD in drug addiction, we first used bioinformatics prediction algorithms together with microarray analyses to search for specific genes and functional networks upregulated within the forebrain of HuD overexpressing mice (HuDOE ). When this set was further limited to genes in the Knowledgebase of Addiction Related Genes database (KARG) that contains predicted HuD-binding sites in their 3' untranslated regions (3' UTR), we found that HuD regulates networks that have been associated with addiction-like behavior...

Syntactic binding refers to combining words into larger structures. Using EEG, we investigated the neural processes involved in syntactic binding. Participants were auditorily presented two-word sentences (i.e. pronoun and pseudoverb such as 'I grush', 'she grushes', for which syntactic binding can take place) and wordlists (i.e. two pseudoverbs such as 'pob grush', 'pob grushes', for which no binding occurs). Comparing these two conditions, we targeted syntactic binding while minimizing contributions of semantic binding and of other cognitive processes such as working memory...

Sleep benefits motor memory consolidation. This mnemonic process is thought to be mediated by thalamo-cortical spindle activity during NREM-stage2 sleep episodes as well as changes in striatal and hippocampal activity. However, direct experimental evidence supporting the contribution of such sleep-dependent physiological mechanisms to motor memory consolidation in humans is lacking. In the present study, we combined EEG and fMRI sleep recordings following practice of a motor sequence learning (MSL) task to determine whether spindle oscillations support sleep-dependent motor memory consolidation by transiently synchronizing and coordinating specialized cortical and subcortical networks...

Memory recall is facilitated when retrieval occurs in the original encoding context. This context dependency effect likely results from the automatic binding of central elements of an experience with contextual features (i.e., memory "contextualization") during encoding. However, despite a vast body of research investigating the neural correlates of explicit associative memory, the neural interactions during encoding that predict implicit context-dependent memory remain unknown. Twenty-six participants underwent fMRI during encoding of salient stimuli (faces), which were overlaid onto unique background images (contexts)...

Anxiety disorders are a category of mental disorders characterized by feelings of anxiety, stress, and fear attached to various sources. However, their pathogenesis is complicated and has not been fully elucidated. The amygdala is a vital brain region that regulates anxiety and mental disorders. Cytoplasmic polyadenylation element binding protein 1 (CPEB1) mediates the extension of the mRNA polyadenylation tail and facilitates the translation of target RNA. CPEB1 is closely related to neuronal diseases, such as Fragile X Syndrome, learning and memory disorders, and chronic pain...

Type 1 diabetes is an autoimmune disease, in which pancreatic β cells are destroyed by autoreactive T cells in genetically predisposed individuals. Serum beta cell autoantibody specificities have represented the mainstay for classifying diabetes as autoimmune-mediated and for stratifying risk in first-degree relatives. In recent years, approaches were attempted to solve the difficult issue of detecting rare antigen-specific autoreactive T cells and their significance to etiopathogenesis such as the use of the MHC multimer technology...

Hippocampal involvement in learning and remembering relational information has an extensive history, often focusing specifically on spatial information. In humans, spatial reconstruction (SR) paradigms are a powerful tool for evaluating an individuals' spatial-relational memory. In SR tasks, participants study locations of items in space and subsequently reconstruct the studied display after a short delay. Previous work has revealed that patients with hippocampal damage are impaired both in overall placement accuracy as well as on a specific measure of relational memory efficacy, "swaps" (i...

Fragile X mental retardation protein (FMRP) encoded by Fragile X mental retardation 1 (FMR1) gene is a RNA-binding regulator of mRNA translation, transport and stability with multiple targets responsible for proper synaptic function. Epigenetic silencing of FMR1 gene expression leads to the development of Fragile X syndrome (FXS) that is characterized by intellectual disability and other behavioral problems including autism. In the rat FXS model, the lack of FMRP caused a deficit in hippocampal-dependent memory...

Anesthetics are used extensively in surgeries and related procedures to prevent pain. However, there is some concern regarding neuronal degeneration and cognitive deficits arising from regular anesthetic exposure. Recent studies have indicated that brain-derived neurotrophic factor (BDNF) and cyclic AMP response element-binding protein (CREB) are involved in learning and memory processes. Genistein, a plant-derived isoflavone, has been shown to exhibit neuroprotective effects. The present study was performed to examine the protective effect of genistein against isoflurane-induced neurotoxicity in rats...

Accumulated evidences displayed that transplantation of stem cells may be a promising approach for the treatment of neurological disorders. However, the underlying mechanisms remain to be well elucidated. Moreover, some investigators can not reproduce similar results as the previous. The present results showed that transplantation of fresh human umbilical cord blood mononuclear cells (cbMNCs) attenuated ischemic damage in middle cerebral artery occlusion (MCAO) rats, accompanied with improvement of neurologic deficits, learning and memory function...

Alzheimer's disease (AD) is a common form of dementia mainly characterized by the deposition of neurofibrillary tangles and β-amyloid (Aβ) peptides in the brain. Additionally, increasing evidence demonstrates that a neuro-inflammatory state plays a key role in the development of this disease. Beside synthetic drugs, the use of natural compounds represents an alternative for the development of new potential drugs for the treatment of AD. Among these, the root of Salvia miltiorhiza Bunge (also known as Danshen) used for the treatment of cardiovascular, cerebrovascular disease and CNS functional decline in Chinese traditional medicine is one of the most representative examples...
