introduction: previous studies have suggested that the cerebellum is a primary site of motor learning. the cerebellar cortex has a particular glial architecture with large astroglial cells. in addition, more recent works have revealed that astrocytes play a more active role in neuronal activity. the aim of this study was to evaluate the number of astrocytes in the molecular layer of rat's ...

s100ß a neurotrophic factor mainly released by astrocytes, has been implicated in the pathogenesis of bipolar disorder. thus, lithium may exert its neuroprotective effects to some extent through s100ß. furthermore, the possible effects of lithium on astrocytes as well as on interactions between neurons and astrocytes as a part of its mechanisms of actions are unknown. this study was undertaken...

The neurovascular unit, composed of neurons, brain endothelial cells, pericytes, microglia, and astrocytes, regulates cerebral blood flow. physical chemical signals govern the physiology unit within network its cellular components. Astrocytes have an essential role in this since they a privileged anatomical relationship with rest cells. They are capable sensing released by their neighboring rel...

abstract: introduction & objective: the hippocampal formation is a part of limbic system that plays an important role in memory and learning. the hippocampus is divided into three subfields: ca1, ca2 and ca3. in addition to pyramidal neurons and interneurons, the astrocytes play important roles in hippocampus, probably in memory and learning. in fact, learning needs some instruments for informa...

objective: astrocytes are the most abundant glial cell type. they may promote or inhibit cns inflammation depending on which cytokines are secreted. astrocytes also have immune roles. il-19, il-20, and il-24 activate a heterodimer receptor composed of the il-20r1 α-chain and the il-20r2 β-chain. it has long been considered that signaling by these receptor complexes affects immunological reactio...

background: astrocytes, which comprise ~90% of overall brain mass, are involved in brain immunity. these cells represent the non-professional class of cns-resident apcs and may promote or inhibit cns inflammation depending on the cytokines they secrete. il-10 family of cytokines and their receptors, il-20r1 and il-20r2, may have a role in shifting astrocytes to a neuroprotective or neurodegener...

introduction: astrocytes are the most abundant glial cell type. in addition to their neurological roles, astrocytes also have immune functions. they have been involved in antigen presentation in the central nervous system (cns). activated astrocytes express adhesion molecules, chemokines and release several inflammatory mediators, pro-inflammatory cytokines, neurotrophic and neuroprotective fac...

background:   astrocytes are cells within the central nervous system which are activated  in a wide spectrum of infections,  and  autoimmune and  neurodegenerative diseases.in pathologic states, they produce  inflammatory cytokines, chemokines,  and  nitric oxide (no), and sometimes  they induce apoptosis.their protease-activated receptors (pars) can be activated by proteases, e.g.thrombin and ...
