Implication
Suggests cell-type-specific excitability control; leaves open translational validation in disease models.
Structured PICO
P
Population
Rat brain neurons (including hippocampal and cortical pyramidal cells, Purkinje cells, and cerebellar basket cells)
I
Intervention
In situ hybridization and immunocytochemical approach to determine subcellular distribution of Kv1.2
O
Outcome
Subcellular distribution of Kv1.2 protein
Kv1.2-containing K+ channels exhibit differential subcellular sorting depending on the neuronal cell type, suggesting diverse functional roles in regulating presynaptic or postsynaptic membrane excitability.
