ONLINE COVER Triggering Hydrocephalus. Using a new mouse model, Yung et al. identify a blood-borne lipid LPA (lysophosphatidic acid) that may trigger development of hydrocephalus, a disorder of newborns in which excess cerebrospinal fluid (CSF) accumulates in the brain. Currently, the only treatment option for hydrocephalus is surgical insertion of an intraventricular shunt to relieve intracranial pressure. Injection of LPA into the brains of fetal mice in utero resulted in accumulation of CSF, such that the mice were born with characteristics of hydrocephalus such as markedly enlarged heads. A drug that blocks the LPA receptor prevented development of hydrocephalus after injection of LPA into fetal mice. LPA receptor antagonist drugs may be a useful adjunct therapy to surgery for treating this incurable disease of newborns. [CREDIT: COVER DESIGN BY C.
