Newly Discovered Immune System Micro-organ Could Aid Better Vaccine Development

Scientists at the Garvan Institute of Medical Research in Sydney, Australia, have identified a previously unknown micro-organ within the immune system, which could lead to new approaches for developing more effective vaccines. Discovered in mice using a live imaging technique known as two-photon microscopy, the thin, flattened structures, given the name subcapsular proliferative foci (SPF),  are located over the surface of draining lymph nodes, and act as a congregation point for immune cel
