Earlier this week, the Nobel Prize in Medicine was awarded to thee researchers for breakthrough work in immunology. Sadly, one of the winners, Ralph Steinman, MD, passed away just days before the prize was announced.
Steinman was awarded one half of the prize for his discovery of the dendritic cells and their role in adaptive immunity. Those cells are shown in the above image as part of a skin section showing large numbers of them in the epidermis. Steinman's work eventually led to the development of a vaccine against advanced prostate cancer.
