Expression of connexin 26 in the ganglionic eminence of preterm infants after bleedings.
The ganglionic eminence being a prominent part of the telencephalic proliferative zone is the most common site of bleedings in preterm infants. This immunohistochemical study demonstrates that connexin 26 involved in forming intercellular gap junctions is expressed in ganglionic eminence cells up to 500 microm from the bleeding. In controls, no positive cells are present. It is discussed that an increase of gap junctional communication may result in spreading of the primary injury.
