WitrynaMice lacking the chemokine receptor Cx3cr1 exhibit a transient reduction of microglia during the early postnatal period and a consequent deficit in synaptic pruning. We show that deficient synaptic pruning is associated with weak synaptic transmission, decreased functional brain connectivity, deficits in social interaction and increased ... Witryna21 mar 2024 · Pruning of synapses by microglia during early development ( Paolicelli et al., 2011; Schafer et al., 2012) already suggests that this physiological role of microglia occurs well before aging or amyloid deposition; thus, its reactivation during aging might not necessarily depend on amyloid.

Further 3D-reconstructed imaging analysis showed significantly more PSD95 + puncta in DS microglia than Cont microglia in GM ( Figures 3 B and 3D).
Witryna29 kwi 2024 · Glia-mediated synaptic pruning is a mechanism of structural plasticity in the healthy central nervous system (CNS), but recently, it has been discovered that dysregulated glia-mediated synaptic pruning is the cause of synaptic degeneration, leading to maladaptive plasticity and cognitive deficits in multiple diseases of the CNS.
