For the first time a complete review of the research work done over the past 30 years by leading investigators around the world in targeting immunosuppressants to both solid-organ and cellular transplants is available in a single volume. One section consists of studies conducted in rat allograft models using osmotic minipumps for delivery of a variety of immunosuppressants. The book will be of great benefit to researchers in the fields of transplant immunology, pharmacology and drug delivery and targeting, particularly those involved in drug development.
