Article Title: CD100 on NK Cells Enhance IFNγ Secretion and Killing of Target Cells Expressing CD72

doi: 10.1371/journal.pone.0000818

Figure Lengend Snippet: Biotinylated 172.4 mAb was used in combination with other fluorescently labeled mAbs in a four color staining. 172.4 staining was detected using Cy-5 streptavidin. Cells were analyzed by flow cytometry. T cells were identified as CD3 positive, NK cells as CD56 positive, CD3 negative, and B cells as CD19 positive. Staining was performed on freshly isolated PBL (A, C and E) and on PBL that were cultured for 72 hr in the presence of IL-2 (100 u/ml) and human serum (B, D and F). Each dot blot shows a gated specific sub-population. An isotype matched antibody was used to determent the background staining for each antibody and is represented in the figure as the horizontal line. (H) Freshly isolated PBMC were incubated for 72 hr with 50 ng/ml of the indicated cytokines. Biotinylated 172.4 mAb was detected using Cy-5 streptavidin and used in combination with other fluorescently labeled mAbs in a four color staining. The PBL were analyzed for the expression of CD100 on NK cells and each dot plot represents a gated NK cells (CD3-, CD56+). Figure shows one representative experiment out of four performed.

Figure Lengend Snippet: (A) Surface radioiodinated YTS cell lysate was immunoprecipitated with mAb 172.4. The immunoprecipitate was analyzed first on non-reducing and then on reducing SDS-PAGE. The left lane is an aliquot of immunoprecipitated proteins resolved under reducing conditions. Molecular weight markers are as shown. The two forms of CD100 (150 and 120 kDa respectively) are indicated with arrows. (B, D) ELISA plates were coated with CD100-Ig and assayed for binding to the indicated antibodies as described in “Materials and Methods”. (C) ELISA plates were coated with CD99-Ig and assayed for binding to the indicated antibodies as described in “Materials and Methods”. The background binding to BSA was subtracted. Figure shows one representative experiment out of four performed. (E) IL-2 activated NK line was stained with either 172.4 or the commercial anti human CD100 antibody A8. FITC conjugated Goat F(ab') anti mouse IgG antibody was used as secondary Ab. Gray histogram is staining with secondary antibody only. Figure show one representative experiment out of 5 performed.

Figure Lengend Snippet: (A) 35 S-labeled activated NK cells were incubated for 20 minutes with adherent BW or BW/CD72 cells. The wells were washed, the remaining cells were lysed and the level of radioactivity was measured in CPM units (counts per mint). The results presented after subtraction of NK cells only. (B) 35 S-labeled activated NK cells were incubated for 20 minutes with adherent BW/CD72 cells that were pre incubated with CD100-Ig or CD99-Ig for 2 hr prior to the incubation with NK cells. The wells were washed, the remaining cells were lysed and the level of radioactivity was measured. *p = 0.02. (C) Activated NK cells were incubated with target cells (BW or BW/CD72), in 37°C, for the indicated time periods. Cells were lysed and proteins were immunoprecipitated by mAb 172.4. The immunoprecipitated proteins were separated on a reducing SDS-PAGE. Phosphorylated proteins were detected in western blot by using rabbit anti phospho-serine polyclonal Ab. CD100 levels were detected in western blot by using the A8 anti human CD100. (D) Densitometrical analysis of the level of phosphorylation on serine residues of the three proteins indicated by arrows in . The levels of phosphorylation are relative to their level at time zero which was set as one. Figure shows one representative experiment out of two performed.
