Although significant advances in our understanding of the immune system have been made in recent decades, we still have much to learn, particularly about the similarities and differences between different immune cells with respect to genomics, proteomics, and transcriptomics. The Human Blood Atlas, described in this poster, furnishes detailed information on the expression levels of all human protein–encoding genes found in major blood immune-cell populations, as well as on the levels of the encoded proteins. Having this information enables researchers to better understand not only the normal function of immune cells, but also how they respond to disease—which may offer clues that can lead to improved treatments and novel therapies.
