Objective:

To examine the therapeutic potential of an anti-HMGB1 neutralizing antibody in improving neurological outcomes in burned and immobilized rats.

Approach:

Key Findings:

• Hindlimb unloading increased burn wound size and elevated IL-10 and IL-1β levels, which were mitigated by anti-HMGB1 treatment.
• Anti-HMGB1 administration moderated the immune response, including activated CD4+ T cells and NK cells.
• Electrophysiological analysis showed that anti-HMGB1 treatment restored normal synaptic function in burned rats, evidenced by normalized potentiation patterns and preserved pre- and postsynaptic function.

Interpretation:

Prolonged immobilization exacerbates burn-induced brain impairment through hyperexcitability at synapses, while early neutralization of HMGB1 protects against inflammation and preserves synaptic plasticity.

Limitations:

• The study was conducted in a rat model, which may limit the generalizability of the findings to humans.
• The long-term effects of anti-HMGB1 treatment beyond the 21-day observation period were not assessed, and the specific mechanisms of action remain to be elucidated.

Conclusion:

Early reduction of systemic HMGB1 activity may protect against neuroinflammation and preserve hippocampal integrity following burn injury and hindlimb unloading.
