WebAug 25, 2024 · The perisynaptic astrocytic processes (PAPs) interact with both synapses and dendrites and regulate synaptic transmission (Ghézali et al., 2016). Furthermore, … WebJul 6, 2024 · We also show that this induction of new translation extends into peripheral astrocyte processes (PAPs). Accordingly, proteomics following fear conditioning in mice, showed that new translation influences peri-synaptic astrocyte protein composition in vivo under physiological conditions.
WebSynapses are enveloped with intricate processes of astrocytes known as perisynaptic astrocytic processes (PAPs). PAPs are motile structures displaying rapid actin-dependent move- ments and are characterized by Ca2+ elevations in response to neuronal activity. Despite a debated implication in synaptic plasticity, the role of both Ca2+ events in ... WebHere, we synthesize the current understanding of astrocyte morphology, coupling local synaptic activity to astrocytic Ca 2+ in perisynaptic astrocytic processes and morphology-defined mechanisms of Ca 2+ regulation in a distributed model. To this end, we build simplified realistic data-driven spatial network templates and compile model ...
WebApr 11, 2024 · Astrocytes are known for their diverse roles in synaptic transmission, which is largely facilitated by the close physical interactions between their fine perisynaptic astroglial processes (PAPs) and the pre- and post-synaptic compartments together forming the “tripartite synapse” [1,2,3].One of their many important functions is the removal of excess … Web1 day ago · Astrocytes are the most abundant type of glial cells that regulate the development of the central nervous system (CNS) by establishing close morphological and functional interactions with the cell bodies, dendrites, dendritic spines, and synaptic contacts of neurons [1-3].A single mouse cortical astrocyte can form contacts with more …
WebApr 10, 2024 · Using in vitro and in vivo methods, we found that the PD-linked gene Lrrk2 controls astrocyte morphology via regulating the phosphorylation of ERM proteins (Ezrin, Radixin, and Moesin), a structural component of the perisynaptic astrocyte processes. ERM phosphorylation is robustly elevated both in mice and humans carrying the LRRK2 …
WebJan 28, 2024 · Perisynaptic astrocytic processes (PAPs) carry out several different functions, from metabolite clearing to control of neuronal excitability and synaptic plasticity. All these functions are likely orchestrated by complex cellular machinery that resides within the PAPs and relies on a fine interplay between multiple subcellular components. … cheap bluetooth laptop mousecheap bluetooth head unitWebWhether the protein plays a role in other astrocyte domains is unknown.
