[The updated advancements in synaptic plasticity mediated by glial cells]

Area of Science:

• Neuroscience
• Cell Biology

Context:

• Historically, research on synaptic plasticity, learning, and memory has primarily focused on neurons and synapses.
• Glial cells, such as astrocytes, microglia, and oligodendrocytes, were long overlooked in these processes.
• Emerging evidence highlights the significant role of glial cells in synaptic function and plasticity.

Purpose:

• To review the current understanding of glial cell involvement in synaptic plasticity.
• To explore the mechanisms by which different glial cell types modulate synaptic function.
• To emphasize the impact of glial cells on learning and memory.

Summary:

• Glial cells are increasingly recognized as integral components of the tripartite synapse.
• Astrocytes, microglia, and oligodendrocytes influence synaptic plasticity through diverse signaling pathways, including glutamate, serine, glycine, and ATP.
• These glial-mediated mechanisms affect synaptic transmission and neuronal network activity.

Impact:

• This research provides new directions for studying synaptic plasticity and its underlying mechanisms.
• Understanding glial cell roles is crucial for clarifying synaptogenesis, learning, and memory processes.
• The findings open avenues for therapeutic strategies targeting glial cells to enhance cognitive functions.
