What is it about?
Many infants that are born premature (before 37 of 40 weeks of pregnancy) will have a bleed inside their brain, an intraventricular haemorrhage (IVH). These bleeds are linked to poor long term outcomes, with increased risks for the child to later develop cerebral palsy, autism or deficits in memory and learning. Fortunately, most infants will survive the bleed, however this leaves us with little opportunity to study in detail the cellular and molecular events occurring in the brain for the goal of developing a treatment. This study describes a clinically relevant animal model of IVH in the preterm born population, and studies in depth how the brain is altered.

Why is it important?
This knowledge if key for pinpointing the specific cellular events that may be novel therapeutic targets. The rabbit is an excellent pre-clinical model of IVH due to its developmental characteristics. This is the first description of the long term impacts of IVH in this model and we uncovered subtle but significant defects in cortical organisation, myelination and microglial reactivity.
