MSK1 Regulates Homeostatic and Experience-Dependent Synaptic Plasticity

MSK1 regulates homeostatic and experience-dependent synaptic plasticity.

The ability of neurons to modulate synaptic strength underpins synaptic plasticity, learning and memory, and adaptation to sensory experience. Despite the importance of synaptic adaptation in directing, reinforcing, and revising the behavioral response to environmental influences, the cellular and molecular mechanisms underlying synaptic adaptation are far from clear. Brain-derived neurotrophic...

Experience-dependent homeostatic synaptic plasticity in neocortex.

The organism's ability to adapt to the changing sensory environment is due in part to the ability of the nervous system to change with experience. Input and synapse specific Hebbian plasticity, such as long-term potentiation (LTP) and long-term depression (LTD), are critical for sculpting the nervous system to wire its circuit in tune with the environment and for storing memories. However, thes...

Synaptopodin regulates denervation-induced homeostatic synaptic plasticity.

Synaptopodin (SP) is a marker and essential component of the spine apparatus (SA), an enigmatic cellular organelle composed of stacked smooth endoplasmic reticulum that has been linked to synaptic plasticity. However, SP/SA-mediated synaptic plasticity remains incompletely understood. To study the role of SP/SA in homeostatic synaptic plasticity we here used denervation-induced synaptic scaling...

Homeostatic Synaptic Plasticity

Homeostatic synaptic plasticity mechanisms provide a means for neurons and circuits to maintain stable function in the face of perturbations such as developmental or activitydependent changes in synapse number or strength. These forms of plasticity use negative feedback signaling to adjust synaptic properties to keep activity close to some internal set point value. Recent work suggests that the...
