CD229 antibody | HLy9.1.25
Mouse anti Human CD229 antibody, clone HLy9.1.25 (MCA2124) used for the detection of SLAMF3 (CD229) using flow cytometry.
Image caption:
SLAMF3 is expressed by hepatocytes. (A) SLAMF3 expression was analysed by flow cytometry analysis in HHPHs and in Huh-7, HepG2 and Hep3B human HCC cell lines. SLAMF3 expression in Jurkat lymphocytes was used as a positive control; SLAMF3 staining (in grey) is overlaid by the negative control (in white) and corresponds to one representative of five independent experiments. (B) Western blot analysis of proteins extracted from Huh-7 cells, HepG2 cells or HHPHs, with a mAb (K12) against SLAMF3′s first extracellular domain (D1) or an anti-actin antibody as a control. One of four independent experiments is presented here. (C) Expression of SLAMF3 transcripts in hepatocytes. After reverse transcription, SLAMF3 cDNA was amplified by PCR using specific primers. GAPDH was amplified as a control gene and pure H2O was used as a PCR control. The Daudi and Jurkat human lymphocyte cell lines were used as positive controls and the monkey kidney COS-7 cell line was used as a negative control. One of three independent experiments is shown here; (D) SLAMF3 mRNA was assayed by Q-PCR in (I) HHPHs, Huh-7 cells and HepG2 cells, (ii) Daudi B lymphocytes and Jurkat T lymphocytes (positive controls) and (iii) the green monkey kidney COS-7 cell line (a negative control). Results are presented as the mean ± SD (n = 6) ***p<0.005, **p<0.01).

Image caption:
Correlation between SLAMF3 expression and HCC cell proliferation. (A) Effects of the introduction of specific siRNAs on SLAMF3 expression in Huh-7 cells. Cells were transiently transfected with a scrambled siRNA (Sc) or one of two pre-designed anti-SLAMF3 siRNAs (referred to as #2 and # 3); SLAMF3 expression was measured by Western blot analysis (anti-SLAMF3, K12). One representative of two independent experiments is shown. (B) siRNA-treated Huh-7 cells were cultured and proliferation was assayed in a Trypan blue exclusion test after 48 h. Proliferation is presented as the mean number of viable cells ± SD (n = 5; statistical significance: ***p<0.005). (C) Following our observation of bimodal SLAMF3 expression, Huh-7 cells were sorted into SLAMF3neg and SLAMF3pos subpopulations, as shown by the dot plot (top panel); SLAMF3 expression in the two enriched populations was measured by flow cytometry (bottom panel); (D) Huh-7 SLAMF3neg and Huh-7 SLAMF3pos cells were cultured separately and cell proliferation was assayed in a Trypan blue exclusion test after 24, 48 and 72 h. Proliferation is presented as mean number of viable cells ± SD (n = 4; statistical significance: **p<0.01, ***p<0.005); SLAMF3 expression was forced in Huh-7 and HepG2 cell lines and proliferation was determined in an MTT assay (E) after 24, 48 and 72 h. The results are presented as the mean ± SD (n = 4; statistical significance: *p<0.05); (F) Investigation of the role of SLAMF3′s first extracellular domain (D1) in the protein’s suppressor effect on HCC proliferation. COS-7 cells (which are naturally negative for SLAMF3) were transfected with a vector coding for wild type SLAMF3 or SLAMF3 lacking D1 (delta-D1 SLAMF3) or a mock pBud vector. Cell proliferation was monitored with MTT assays performed 24 and 72 h after transfection. The results are presented as the mean ± SD (n = 3; statistical significance: *p<0.05, **p<0.01, ***p<0.005; ns: non-significant).

Image caption:
Restoration of SLAMF3 expression in HCC cells inhibits MAPK ERK1/2, JNK and mTOR pathways and induces caspase-dependent apoptosis. (A) SLAMF3 expression was confirmed by Western blot analysis in SLAMF3-over-expressing Huh-7 and mock cells at 48 h post-transfection. ERK1/2, JNK, p38, AKT and mTOR proteins were detected as controls. The activation levels of MAPK ERK1/2 (Thr 202/Tyr 204), JNK (Thr 183/Tyr 185), p38 (Thr 180/Tyr 183), PI3K (p85/p110 Thr 467/Tyr 199), AKT (Ser 473, Thr 308) and mTOR (Ser 2448, Ser 2481) are represented. One of three representative experiments is shown here. (B) The results of an active caspase assay based on cell-permeable fluorochrome inhibitor of caspases (FLICA). Caspase activity was evaluated in HCC cells (Huh-7 and HepG2 lines) at the indicated times after the ectopic introduction of SLAMF3 vector. Caspase activity is shown in the SLAMF3neg subpopulation (in white) and the SLAMF3pos (overlaid in grey) subpopulation from one representative of two independent experiments.

SLAMF3 over-expression increases hepatocyte permissiveness to HCV. Huh-7 cells were transfected with empty vector pBud (mock) or human SLAMF3 (to yield Huh-7+ cells) and incubated with HCVcc. (A) SLAMF3 expression was analyzed by flow cytometry (HLy9.1.25 clone) and (B) visualized by confocal microscopy in one out of three experiment. Unshaded histograms show the isotype-matched control (Co) and shaded histograms show SLAMF3 expression). (C, D, E) Infection was assessed at 4 and 72 h p.i. as the number of FFUs and (F and G) by flow cytometry analysis; (C) intracellular E2 (stained red) were measured at 4 h and 72 h p.i. Green staining corresponds to the SLAMF3 expression. One of three representatives independent experiments is shown. (D) The HCV permissiveness of Huh-7 mock and Huh-7+ cells was evaluated in terms of the number of FFUs based on intracellular E2 viral protein staining and (E) fluorescent microscopy analysis (mean of five experiments; error bars: SD; *p<0.05); Infection evaluation by flow cytometry analysis measuring the intracellular viral E2. (F) Infected cells (72 p.i.) were stained for surface expression of SLAMF3 (HLy9.1.25 clone) and permeabilized for intracellular E2 staining. The percentage of positive cells in each cell population is indicated in the corresponding quadrant (one of three representative experiments is shown) and (G) as a mean of three experiments (error bars: SD; *p<0.05).

SLAMF3 blockade in human hepatocytes is associated with lower susceptibility to HCV. (A) SLAMF3 was stained in primary human hepatocytes (PHHs) and cells from the Huh-7 human hepatoma cell line with a specific antibody (HLy9.1.25 clone; grey) and an isotype-matched control (empty). One of four independent experiments is shown. Huh-7 cells were transfected with scrambled control (sc) siRNA or three specific siRNAs (#1, #2 and #3) targeting SLAMF3, prior to infection with HCVcc; siRNA efficiency was checked by quantifying SLAMF3 mRNA (B) and the CD81 expression level (C) by flow cytometry analysis at 48 h post-transfection. Results are presented as the mean ±SD (n = 3). Intracellular viral RNA was quantified at 72 h p.i. (D) and the infection was measured at 72 h p.i. by focus-forming units FFUs counting (E) (as inhibition percent; mean of three independent experiments; error bars: SD. **p<0.01);

Mouse anti Human CD229 antibody, clone HLy9.1.25 recognizes the human cell surface antigen CD229 also known as T-lymphocyte surface antigen Ly-9 or SLAM family member 3. CD229 is a 608 amino acid single pass type I transmembrane glycoprotein of ~120 kDa as evaluated by immunoprecipitation of cells transfected with the full length human CD229 cDNA. However immunoprecipitation of CD229 from Daudi cell lysates with dlone HLy9.1.25 yields bands of 120 kDa corresponding to the full length CD229 and a 100 kDa band attributed to an alternatively spliced isoform lacking the fourth Ig-like domain (de la Fuente et al. 2001).
Human CD299 is expressed on thymocytes, T-cells and B-cells (Del Valle et al. 2003). CD229 has also been described as a tumor associated antigen in chronic lymphocytic leukemia (Bund et al. 2006) and has been implicated in the development of spontaneous autoantibody production to nuclear antigens in mice and is potentially a target for the treatment of autoimmunity (de Salort et al. 2013).
