Pericytes are mural cells embedded in the basement membrane of microvessels. Because of such a unique position in the blood-brain barrier (BBB) and neurovascular unit (NVU), they receive, orchestrate and process signals from their neighboring cells to generate diverse neurovascular functions, including regulation of capillary hemodynamics, BBB permeability, clearance of toxic metabolites, angiogenesis, neuroinflammation and stem cell activity. During the different stages of ischemic stroke, pericytes play different roles: 1) On the hyperacute phase of stroke, pericytes constriction and death may be a cause of the no-reflow phenomenon in brain capillaries; 2) During the acute phase, pericytes detach from microvessels and participate in inflammatory-immunological response, resulting in the BBB damage and brain edema...

Minipump infusions into visual cortex in vivo at the onset of the critical period have revealed that the proinflammatory cytokine leukemia inhibitory factor (LIF) delays the maturation of thalamocortical projection neurons of the lateral geniculate nucleus, and tecto-thalamic projection neurons of the superior colliculus, and cortical layer IV spiny stellates and layer VI pyramidal neurons. Here, we report that P12-20 LIF infusion inhibits somatic maturation of pyramidal neurons and of all interneuron types in vivo...

BACKGROUND: Mood disorders, consisting of unipolar and bipolar depression, are complex diseases characterized by depressed mood and anhedonia. These core symptoms are accompanied in a varying manner by anxiety, several neurovegetative symptoms and cognitive impairment. Mood disorders are characterized by decreases in neurogenesis, alteration in synaptic structure and synaptic transmission, all of them regulated by BDNF, a neurotrophin that performs multiple functions in the adult central nervous system...

BACKGROUND: Macrophages/microglia are important effector cells at the site of spinal cord injury (SCI). M1-type macrophages facilitate innate immunity to remove foreign microbes and wound debris from the injury site. M2-type macrophages exhibit tissue repair properties and attenuate production of pro-inflammatory cytokines. Regulation of the polarisation of M1/M2 macrophages may affect the inflammatory response in SCI and may be related to neurotrophin-3 (NT-3). Electroacupuncture (EA) at GV acupuncture points can be used as an adjuvant therapy for SCI...

OBJECTIVE: Rewiring of excitatory glutamatergic neuronal circuits is a major abnormality in epilepsy. Besides the rewiring of excitatory circuit, an abnormal depolarizing GABAergic drive has been hypothesized to participate in the epileptogenic processes. However, a remaining clinically relevant question is whether early post Status Epilepticus (SE) evoked chloride dysregulation is important for the remodeling of aberrant glutamatergic neuronal circuit. METHODS: Osmotic mini-pumps were used to infuse intracerebrally a specific inhibitor of depolarizing GABAergic transmission as well as a functionally blocking antibody towards the pan-neurotrophin receptor p75 (p75(NTR) )...

Neurotrophins particularly brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) are crucial modulators in the neurodevelopment and maintenance of central and peripheral nervous systems. Neurotrophin hypothesis of schizophrenia (SCZ) postulated that the changes in the brains of SCZ patients are the result of disturbances of developing processes involving neurotrophic factors. This hypothesis was mainly supported by the abnormal regulation of BDNF in SCZ, especially the decreased peripheral blood BDNF levels in SCZ patients validated by several meta-analyses...

Temporal lobe epilepsy (TLE) is the most common form of adult epilepsy and frequently evolving drug resistance. Although there is growing consensus that noncoding ribonucleic acids (ncRNAs) are modulators of TLE, the knowledge about the deoxyribonucleic acid (DNA) methylation patterns of ncRNAs in TLE remains limited. In the current study, we constructed DNA methylation profiles from 30 TLE patients and 30 healthy controls for ncRNAs, primarily focusing on long ncRNAs (lncRNAs) and microRNAs (miRNAs), by reannotating data of DNA methylation BeadChip...

Nerve growth factor (NGF) is an important member of the neurotrophin family and its alteration has been associated with psychiatric disorders. Functionality consists of the activities that an individual can perform, as well as their social participation, which is an important factor in analyzing the carrier living conditions of subjects with psychiatric suffering. Several studies have evaluated functionality in bipolar disorder; however, no studies have evaluated the functionality in other mental disorders...

BACKGROUND: Morphine is an opioid analgesic used to relieve moderate-to-severe pain, including pain in neonates at the intensive care unit. In our previous study, we showed that repeated morphine exposure during early life could trigger long-lasting implications on the developing nervous system, such as long-term neurochemical and behavioral alterations in adult rats. AIMS: The aim of our study was to determine the short-, intermediate-, and long-term effects of repeated morphine administration during early life on the thermal and mechanical thresholds and on the central levels (cerebral cortex and brainstem) of neurotrophins (brain-derived neurotrophic factor [BDNF] and nerve growth factor [NGF]) and cytokines (interleukin-6 [IL-6] and IL-10)...

In the mouse cerebellum, Ca(2+)-dependent activator protein for secretion 2 (CADPS2, CAPS2) is involved in regulated secretion from dense-core vesicles (DCVs), which contain neuropeptides including brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3). Capds2 knockout (KO) mice show impaired cerebellar development in addition to autistic-like behavioral phenotypes. To understand the molecular impact caused by loss of Capds2, we analyzed gene expression profiles in the Capds2 KO cerebellum using a GeneChip microarray and the KEGG Pathway database...

After peripheral nerve injury, motor and sensory axons are able to regenerate but inaccuracy of target reinnervation leads to poor functional recovery. Extracellular matrix (ECM) components and neurotrophic factors (NTFs) exert their effect on different neuronal populations creating a suitable environment to promote axonal growth. Here, we assessed in vitro and in vivo the selective effects of combining different ECM components with NTFs on motor and sensory axons regeneration and target reinnervation. Organotypic cultures with collagen, laminin and nerve growth factor (NGF)/neurotrophin-3 (NT3) or collagen, fibronectin and brain-derived neurotrophic factor (BDNF) selectively enhanced sensory neurite outgrowth of DRG neurons and motor neurite outgrowth from spinal cord slices respectively...

BACKGROUND: Recent clinical studies have indicated the beneficial impact of dietary flavonoid intake on human cognitive performance. Although the mechanisms that mediate such improvements are currently unclear, animal and human trial data suggest that changes in neurotrophin expression, and related signalling apparatus, may be involved. OBJECTIVE: To investigate the link between changes in serum brain-derived neurotrophic factor (BDNF) and changes in human cognitive performance following flavonoid intake. METHODS: The relationship between serum levels of BDNF and age, gender, BMI, waist circumference, blood pressure and cognition at baseline, and following flavonoid intake, was investigated in two distinct randomised, controlled clinical trials...

Recent studies demonstrate that exposure to stress changes the composition of the intestinal microbiota, which is associated with development of stress-induced changes to social behavior, anxiety, and depression. Stress during pregnancy has also been related to the emergence of these disorders; whether commensal microbes are part of a maternal intrauterine environment during prenatal stress is not known. Here, we demonstrate that microbiome changes are manifested in the mother, and also found in female offspring in adulthood, with a correlation between stressed mothers and female offspring...

REVIEW
Veronica Begni, Marco Andrea Riva, Annamaria Cattaneo
Brain-derived neurotrophic factor (BDNF) is a neurotrophin that plays a key role in the central nervous system, promoting synaptic plasticity, neurogenesis and neuroprotection. The BDNF gene structure is very complex and consists of multiple 5'-non-coding exons, which give rise to differently spliced transcripts, and one coding exon at the 3'-end. These multiple transcripts, together with the complex transcriptional regulatory machinery, lead to a complex and fine regulation of BDNF expression that can be tissue and stimulus specific...

Dietary interventions are currently being discussed as additional treatment options for mental disorders. The pathological mechanisms are not yet fully understood. It is hypothesized that certain nutrients and dietary pattern influence immune and inflammatory processes, the microbiome, the leptin-melanocortinergic axis and hypothalamic-pituitary axis, as well as neurotransmitters of the cholinergic, noradrenergic, dopaminergic and serotonergic signaling cascades and neurotrophins. Observational studies have shown that traditional dietary patterns, such as the Mediterranean diet have a protective effect on mental health...
