As shown in Figure 7K tumor growth was increased in CCL25-deficient recipients, and a detailed analysis of immune cell infiltrates revealed a significantly increased number of FoxP3 CD4+ T cells (Figure 7L), which was accompanied by a significantly larger number of PDI-expressing cells (Figure 7M) but without upregulation of this molecule on a per cell basis (Figure 7N). The gene discussed is CD4; the disease is neoplasm.
