mesenchymal stem cells (mscs) have the ability to differentiate into neuronal like cells under appropriate culture condition. in this study, we investigated whether mscs derived from human peripheral blood (pb-mscs) can differentiate into neuronal like cells by synergic effect of the growth factors egf, bfgf and noggin. for this purpose, the expression of five neuronal markers (nestin, β iii tu...

objective:coriandrum sativum (c. sativum) as a medicinal plant has been pointed to have analgesic, hypnotic and anti-oxidant effects. in the current study, a possible preventive effect of the hydro-alcoholic extract of the plant on neuronal damages was examined in pentylenetetrazole (ptz) rat model of seizure.materials and methods: forty male rats were divided into five main groups and treated ...

abstract aim: to assess anti-neuronal antibodies (na) prevalence and their correlation with neurological disorders and bowel habits in celiac disease (cd) patients. background: neurological manifestations are estimated to occur in about 10% of celiac disease patients and na to central nervous system (cns) and enteric nervous system (ens) are found in a significant proportion of them. little is ...

Networks are widely used to represent interaction pattern among the components in complex systems. Structures of real networks from different domains may vary quite significantly. Since there is an interplay between network architecture and dynamics, structure plays an important role in communication and information spreading on a network. Here we investigate the underlying undirected topology ...

Mammalian puberty requires complex interactions between glial and neuronal regulatory systems within the hypothalamus that results in the timely increase in the secretion of luteinizing hormone releasing hormone (LHRH). Assessing the molecules required for the development of coordinated communication networks between glia and LHRH neuron terminals in the basal hypothalamus, as well as identifyi...

Neurons generated from pluripotent stem cells (PSCs) self-organize into functional neuronal assemblies in vitro, generating synchronous network activities. Intriguingly, PSC-derived neuronal assemblies develop spontaneous activities that are independent of external stimulation, suggesting the presence of thus far undetected intrinsically active neurons (IANs). Here, by using mouse embryonic ste...

Neurodegeneration is a progressive and irreversible loss of neuronal cells in specific regions of the brain. Alzheimer Diseases (AD) Parkinson Disease (PD) are the most common forms of neurodegenerative diseases in older people. Exosomes are extracellular nanovesicles that have a key role in physiological processes such as intercellular communication, cell migration, angiogenesis, and anti-tumo...

Communication is a central theme in biology. Consequently, specialized structures have evolved to permit rapid communication among cells, tissues, organs, and physiological systems, thus enhancing the overall function and adaptation of the organism. A prime example is the neuronal synapse. In the brain, synaptic communication establishes neuronal networks with the capacity to integrate, process...

UNLABELLED Behavioral states are commonly considered global phenomena with homogeneous neural determinants. However, recent studies indicate that behavioral states modulate spiking activity with neuron-level specificity as a function of brain area, neuronal subtype, and preceding history. Although functional connectivity also strongly depends on behavioral state at a mesoscopic level and is glo...

A number of studies have contributed to demonstrate that neurons and astrocytes tightly and actively interact. Indeed, the presence of astrocytes in neuronal cultures increases the number of synapses and their efficiency, and thanks to enzymatic and uptake processes, astrocytes play a role in neuroprotection. A typical feature of astrocytes is that they establish cell-cell communication in vitr...
