Contemporary Topics in Immunobiology

The problem that virtually all cells have in discriminating between "self" and "non-self" molecules and cells has been considered at great length in immuno­ biology. However, cells that clearly are incapable of carrying out mammalian­ type immune functions can exhibit exquisite specificity in their capacity to discriminate among syngeneic, allogeneic, and xenogeneic cells. In this volume of Contem...
