Growth Hormone Effects on Hypoxia-Induced Neuroinflammation in the Developing Cerebellum.

ABSTRACT: The central nervous system is highly vulnerable to oxygen deprivation during the neonatal period, leading to long-term neurological damage. Growth hormone (GH) has shown neuroprotective and neuroregenerative effects in response to hypoxic injury. This study investigated GH effects on cell survival, inflammatory, and glial activation markers in the developing cerebellum, as well as its impact on motor coordination and anxiety-like behaviors in adulthood following neonatal hypoxia. Global hypoxia was induced in postnatal day 2 Wistar rats (8% O₂, 2 h), followed by subcutaneous GH treatment (0.1 mg/kg/d) for five days. Neonatal hypoxia triggered a sustained inflammatory response in the developing cerebellum, with increased expression of TLR-4, IL-1β, TNF-α, IL-6, COX-2, iNOS, and p
