A dissolvable microneedle patch delivers the regenerative protein IL-4 directly to damaged heart tissue post-heart attack, initiating a healing response. This targeted delivery alters immune cell activity, promoting tissue repair and enhancing communication between heart muscle and blood vessel cells. By bypassing systemic administration of IL-4, the patch minimizes potential side effects. This innovative approach demonstrates potential as a minimally invasive treatment option to improve heart recovery after a heart attack.
