Implication

Findings reveal altered microglial cell morphology and phagocytic activity in pineal gland, suggesting age-dependent changes impact melatonin production.

Key Points

Microglial cell morphology transitions at night, suggesting increased phagocytic activity.
Density of IBA1 + microglial cells remained constant across light:dark cycles in 3-month-old male rats.
Immunofluorescence staining revealed significant insights into microglial responses in the pineal gland.
Changes in microglial behavior could influence nocturnal melatonin production and overall brain health.
