Scientists discover dendritic cells key to activating human immune responses

Scientists at A*STAR’s Singapore Immunology Network (SIgN), in collaboration with Newcastle University, UK, the Singapore Institute of Clinical Sciences and clinicians from multiple hospitals in Singapore, have identified a new subset of dendritic cells (DCs) in human peripheral tissue which have a critical role in activating our immune response against harmful pathogens. This research will have significant impact on the design of vaccines and other targeted immunotherapies. The scientists also showed for the first time that DC subsets are conserved between species, facilitating the translation of mouse functional DC studies to the human setting. These research findings were published in the July issue of the prestigious journal Immunity.
