Association of Immunosuppression with DR6 Expression during the Development and Progression of Spontaneous Ovarian Cancer in Laying Hen Model

Figure 4

Changes in the frequency of CD8+ T cells in the ovaries of hens during the development and progression of ovarian cancer (OVCA). (a) Compared to the normal, frequency of CD8+ T cells was significantly greater () in the stroma of the tumor at early stage and increased further in late stage OVCA. (b) In contrast to the influx of stromal CD8+ T cells, the frequency of the intratumoral CD8+ T cells did not increase significantly during OVCA progression to late stage. Bars with different letters indicate significant differences in CD8+ T cells among hens of different pathological groups.
