Researchers created a dissolvable microneedle patch that delivers IL-4 directly to damaged heart tissue, jump-starting repair after a heart attack. The targeted approach shifts immune cells into a healing mode while improving communication between heart muscle and blood vessel cells. It avoids the systemic risks of IL-4 injections and shows promise for future minimally invasive treatment.
