student in Schneck's laboratory, tested the impact of these smaller particles.

The so-called nano-aAPCs were small enough that many of them could bind to a single T cell, as the team had expected. But when Perica compared naive T cells to those that had been activated, he found that the naive cells were able to bind more nanoparticles. "This was quite surprising, since many studies had already shown that naive and activated T cells had equal numbers of receptors," Schneck says. "Based on Karlo's results, we suspected that the activated cells' receptors were configured in a way that limited the number of nanoparticles that could bind to them."

To see whether there indeed was a relationship between activation and receptor clustering, Perica applied a magnetic field to the cells, causing the nano-aAPCs to attract one another and cluster together, bringing the receptors with them. The clustering did indeed activate the naive T cells, and it made the activated cells even more active effectively ramping up the normal immune response.

To examine how the increased activation would play out in living animals, the team treated a sample of T cells with nano-aAPCs targeting those T cells programmed to battle melanoma. The researchers next put the treated cells under a magnetic field and then put them into mice with skin tumors. The tumors in mice treated with both nano-aAPCs and magnetism stopped growing, and by the end of the experiment, they were about 10 times smaller than those of untreated mice, the researchers found. In addition, they report, six of the eight magnetism-treated mice survived for more than four weeks showing no signs of tumor growth, compared to zero of the untreated mice.

"We were able to fine-tune the strength of the immune response by varying the strength of the magnetic field and how long it was applied, much as different doses of a drug yield different effects," says Perica. "We think this is the first time magneti
