Cytotoxic T Cells target tumor cells

Most tumor cells, express MHC class I molecules on their surface, cytotoxic T cells can directly recognize them. 

cytotoxic T cells can result in killing of the tumor cells by two different mechanisms

Phytovolatilization

Plants remove inorganic contaminants· either by contaminant volatilization or by metal accumulation.

Volatalization is useful for the removal of mercury. A bacterial mercuric ion reductase has been transferred to Arabidopsis thaliana; this transgenic plant absorbs mercury, and reduces it to volatile Hg0, which volatilizes from the leaf surface.

Nirenberg and Matthaei therefore concluded that the triplet codon UUU encodes phenylalanine, poly(C) proline (polyproline), polyadenylate, poly(A), encodes polylysine.
