Fig. 5From: Effects of stimulating interleukin -2/anti- interleukin -2 antibody complexes on renal cell carcinomaImmunohistochemical analysis of immune cell infiltration into RCC lesions. Tumors were harvested on day 28 after mice were implanted with RENCA cells and immune cells were detected by immunohistochemistry. The size of immune cell populations, including (a) CD4+ T cells, (b) CD8+ T cells, (c) NK cells and (d) macrophages along tumor margins was increased by IL-2C treatment. Images are shown at 200× magnification. Insets show immunoreactive cells at 1000× magnificationBack to article page
