The percentages of HLA-DR+CD45+ antigen-presenting cells and HLA-DR+CD45+CD11c+ dendritic cells were higher in the SB and the combined (SB + NB + TB) groups in KCS than the control eyes (Figure 3A–E); however, percentages in the exposed NB + TB conjunctiva were not greater than the control. The gene discussed is ITGAX; the disease is dry eye syndrome.
