In order to evaluate the capacity of other tumor cell types to express MICA and MICB, as well as NKG2D, we evaluated the possible expression of these proteins in two human epithelial cervical cancer cell lines, CALO and INBL, using polyclonal antibodies against MICA/MICB and anti-NKG2D for western blot and flow cytometric analyses. Here, MICA is linked to cervical carcinoma.
