Distribution of SNAP-25 in transient neuronal circuitries of the developing human forebrain.
The distribution of SNAP-25 is demonstrated within prominent transient structures in the developing human forebrain. During early fetal development SNAP-25 is mainly expressed in axons of the intermediate zone and the internal capsule. The fibers appear directed towards the mantle zone of the ganglionic eminence and the perireticular nucleus located within the internal capsule. Cells of these two areas are shown to interact with SNAP-25 immunoreactive structures with the aid of double-labellings. The SNAP-25 immunoreactive fibers may represent corticofugal axons which contact the perireticular nucleus and ganglionic eminence which are regarded as intermediate targets providing a scaffold for growing axons. Anti-SNAP-25, thus, is an appropriate marker of intermediate targets which are involved in brain injuries of preterm infants.
