46.   In most cases of infection, the body mobilizes immune cells to surround and digest invading bacteria.

47.   It also looked at survival and clinical data such as immune cell counts.

48.   It is a place where immune cells congregate, especially when there is contact with poison ivy, poison oak or certain dyes and cosmetics.

49.   It does not squeeze them or harm them in any way, but sure enough, their immune cell count plummets.

50.   It lies with something called the mast cell, an immune cell and major player in allergic reactions.
