Researchers Made Molecules That 'Dance' Into the Brain After Stroke

Key Points:

Scientists at Northwestern University have developed an intravenous nanomaterial, based on supramolecular peptide assemblies, that crosses the blood-brain barrier and actively repairs brain damage after stroke in preclinical mouse models.
The injectable therapy, known as IKVAV-PA, reduces tissue damage and inflammation by targeting the harmful immune response triggered when blood flow is restored after an ischemic stroke, without causing toxicity or side effects in major organs.
In treated mice, infarct size was significantly reduced from nearly 27% to around 11%, and markers of cellular stress and inflammation were lowered, though no short-term behavioral improvements were observed, indicating the need for longer-term studies.
The nanomaterial self-assembles dynamically, allowing
