oops, I think I meant Dendritic cells.
"In the 1970s, when most scientists were studying how the body reacted after an invasion by a microbe, Dr. Steinman began focusing on the initial steps of invasion. He discovered a rare cell in mouse spleens that moved in a distinctive way under laboratory conditions. The cell acted differently from other immune cells. For example, long projections emerged from the cells and floated before they retracted, creating a starlike pattern. He named them dendritic cells after the Greek word for tree.

Although dendritic cells comprise only 1 percent of mouse spleen cells, Dr. Steinman found that they were the most powerful cell in priming the immune system. The dendritic cell can adjust the body’s defenses by stimulating different T immune cells.

“No one had anticipated that any cell could so efficiently goad T cells into action,” said Dr. Joseph L. Goldstein, the chairman of the Lasker jury and a Nobel laureate from the University of Texas Southwestern Medical Center in Dallas.

Dr. Steinman found that as dendritic cells mature, they migrate from the skin and other tissues to nearby lymph nodes."
