Study finds a possible biological cause for sudden infant death syndrome

New Delhi, May 25 (PTI) Researchers have found an altered serotonin 2A/C receptor in infants who died from sudden infant death syndrome (SIDS), a biological abnormality that they think made these infants vulnerable to death under certain circumstances.

SIDS is the inexplicable death of an infant, generally in their sleep, before their first birthday despite a thorough investigation for its cause.

Previous research in rodents has shown 2A/C receptor signalling to contribute to arousal and autoresuscitation, protecting brain oxygen status during sleep.
