Prolactin Receptor Deficiency Promotes Hypomyelination in White Matter Tracts During Postnatal Central Nervous System Maturation in Mice. [PDF]

Glia
Prolactin action is essential for proper myelination of white matter tracts during neonatal and prepubertal stages in mice. Lack of prolactin receptor (Prlr−/−) signaling leads to hypomyelination and impaired locomotor function. ABSTRACT A large wave of myelination in the central nervous system (CNS) of mammals occurs during postnatal development ...
