Nano immune boost

Biological, as opposed to small molecule, pharmaceutical products work when triggering an immune system response in the body. Researchers at Selecta Biosciences have demonstrated how polymer nanoparticles carrying immunosuppressant agents, such as rapamycin, can be used instead of triggers to modulate the immune response in conditions where the immune system is over-reacting to the patient's own tissues, gout and arthritis, for example, and in post-transplant patients, for instance.
