The Genetic Driver of Acute Necrotizing Encephalopathy, RANBP2, Regulates the Inflammatory Response to Influenza A Virus Infection

Nature Communications | February 6, 2026

Researchers found that RANBP2 plays an important role in controlling the body’s inflammatory response to Influenza A. ANE-associated changes in RANBP2 may disrupt this protective role, leading to increased viral activity and an exaggerated inflammatory response—providing new insight into why some individuals are genetically predisposed to ANE.

A Pilot Study of Peripheral Blood tsRNA Expression Profiling in Children with Influenza-Associated Acute Necrotizing Encephalopathy

Virology Journal | April 2026

Researchers identified distinct changes in small RNA molecules in the blood of children with influenza-associated ANE compared with children with uncomplicated influenza and healthy children. These findings may help researchers better understand what drives ANE and could eventually contribute to earlier, less invasive diagnostic biomarkers and new treatment targets.

“When the Brain Slows Down the Heartbeat”: Reflectory Bradycardia due to Brainstem Lesions in Acute Necrotizing Encephalopathy Caused by Influenza B

Journal of Pediatric Neurology | 2026

This report describes a case of Influenza B–associated acute necrotizing encephalopathy in which brainstem involvement was associated with significant slowing of the heart rate (bradycardia). It highlights how ANE-related brain lesions can affect functions beyond the brain itself and reinforces the importance of close neurological and cardiovascular monitoring.

Higher-dose methylprednisolone improves neurologic outcomes in ANE

Contemporary Pediatrics | February 18, 2026

A study of children with ANE found that a higher dose of methylprednisolone (30 mg/kg/day), given alongside tocilizumab and IVIG, was associated with better neurological outcomes than a lower dose. The findings support continued research into early, aggressive immunotherapy and optimal treatment protocols for ANE.

Influenza A-Associated Acute Necrotizing Encephalitis With Complete Recovery Following Early Immunomodulatory Therapy

Cureus Journal of Medical Science | 2026

This case report describes a patient with Influenza A–associated ANE who experienced complete neurological recovery following early immunomodulatory treatment. It highlights the potential importance of rapid recognition and early treatment in improving outcomes for patients with ANE.
