CD8 Alpha antibody | YTS105.18
Rat anti Mouse CD8 antibody, clone YTS105.18 (MCA1108G) used to demonstrate the presence of CD8 expressing T cells in the ilium of neonatal rats by immunofluorescence on cryosections.
Recruitment of inflammatory cells in the intestine of neonates after CpG-ODN treatment. Eight-day-old neonatal mice received 20 μg/g of CpG-ODN orally. Twenty-four hours after treatment, ilea were removed to analyze the recruitment of inflammatory cells by immunohistology. Six to ten neonates from different litters (5 sections for each animal) per group were analyzed. Data were analyzed by non-parametric Mann-Whitney test.

Rat anti Mouse CD8 antibody, clone YTS105.18 (MCA1108G) used to identify infiltrating CD8 positive T cells in tumors by immunofluorescence.
NKG2D-dependent infiltration of CD8+T cells into tumors. Tumors were collected from mice that had received one of the four standard treatments: control DNA, Dox plus control DNA, IL-12, Dox plus IL-12 (n = 3 per treatment group). (B) NKG2D/CD8–positive cells in tumor sections by treatment received. Frozen tumor sections were stained with biotin anti-mouse NKG2D, anti-mouse CD8, or corresponding isotype control antibodies, then with streptavidin-conjugated Alexa fluor 594 or Alexa fluor 488 secondary antibodies. Data shown are representative of three independent experiments. The scale bar is equivalent to 100 μm.

The effect of NK cell or CD8+T cell depletion on NKG2D-positive lymphocyte localization in tumors. Groups of mice (n = 3 per treatment group) were subjected to one of the four standard treatments: control DNA, Dox plus control DNA, IL-12, Dox plus IL-12. Tumor sections were stained as detailed in the Figure 3 legend. (A) Detection of NKG2D-positive cells in tumors from NK cell–depleted mice, (B) Absence of NKG2D-positive cells in CD8+T cell–depleted mice. Data shown are representative of three independent experiments. The scale bar is equivalent to 100 μm.

The effect of NKG2D-blocking antibody on NKG2D-positive CD8+T cells and CD8+T cell accumulation in tumors. 4T-1 tumor–bearing mice were subjected to one of two treatments: Dox plus IL-12 plus control IgG or Dox plus IL-12 plus NKG2D-blocking antibody (n = 3 per treatment). (A) NKG2D expression in CD8+T cells was determined as described for Figure 1 (n.s., not significant). (B) The presence of NKG2D/CD8–positive cells in tumor sections after the indicated treatments were determined as described for Figure 3.

Image caption:
ttIL-12 enhanced infiltration of CD8+ T cells into tumors, decreased infiltration of Tregs and MDSCs, and increased tumor levels of IFNγ. Frozen sections from 4 T1 primary tumors were stained with CD8 antibody (upper panels) or FOXP3 antibody (lower panels). FOXP3 is a marker of T regulatory cells (Tregs). Representative sections are shown. Scale bars, 100 μm. Absolute numbers of CD8+ cells and FOXP3+ cells were determined by microscopy. *P <0.05, **P <0.01, ***P <0.001, ****P <0.0001
