Null Cells

A third class of lymphocytes are called null cells. Null cells are not dependent on the thymus and they can attack certain types of specific cells without prior sensitization. This category includes killer (K) cells, which aid in the destruction of antibody-coated targets, and natural killer (NK) cells, which can lyse targeted cells.
