SuperArray Bioscience Corporation pathwayfinder cdna array

CD4 + CD28 null T cell clones express CD158b/j, but do not express KARAP/DAP12. CD4 + CD28 null T cells were sorted from patients with RA, and clones were established by limiting dilution. Clones were analyzed by flow cytometry for expression of CD28 and CD158b/j. Four representative clones (#1 through #4) are shown. All clones expressed CD4 (unpublished data; A). RT-PCR was used to amplify transcripts for KARAP/DAP12 and β-actin from PBMCs (lane 1), Jurkat T cells (lane 2), and CD4 + CD28 null T cell clones #1–#4 (lanes 3–6, respectively). <t>cDNA</t> was omitted for the negative control (lane 7) (B). Western blotting was used to detect KARAP/DAP12 and β-actin protein (bottom panels) in Jurkat T cells (lane 1), Jurkat T cells transfected with KARAP/DAP12 + vaccinia virus (lane 2), and CD4 + CD28 null T cell clones (lanes 3–7) (C).

Stimulation through CD158b/j results in an up-regulation of ATF-2 and HSP27 transcripts. The PathwayFinder cDNA Array is spotted in duplicate with 23 cDNAs. Represented on the membrane are the ERK (egr-1 and c-fos), JNK (ATF-2, hsf1, HSP27, and HSP90), NF-κB (iNos, NF-κB, and IκBα), NFAT (IL-2, Fas, and CD5), TGF-β (p16, p21, and p57 Kip2 ), Wnt (c-myc), p53 (p21, gadd45, pig7, pig8, mdm2, and bax), and CREB pathways (egr-1, CYP19, and c-fos). The membrane also included a negative control (pUC18) and two positive controls (β-actin and GAPDH) (A). A CD4 + CD28 null CD158b/j + T cell clone was stimulated with control mouse IgG or anti-CD158j mAb and cross-linked with rabbit anti–mouse IgG Ab. Total RNA was harvested and used to probe the PathwayFinder cDNA Array (B).

Phosphorylation of JNK is initiated by stimulation specifically through CD158j. Two CD4 + CD28 null CD158j + T cell clones (top panels) and a CD4 + CD28 null CD158b1 + T cell clone (bottom panels) were stimulated with anti-CD3 and/or anti-CD158b/j mAbs and cross-linked with rabbit anti–mouse IgG Ab. After SDS-PAGE and transfer to a nitrocellulose membrane, the cell lysates were analyzed for phosphorylation of JNK (left panels). The blots were then stripped and reprobed with Abs against total JNK (right panels; A). Jurkat T cells were infected with either wild-type vaccinia virus (WR) or vaccinia virus containing CD158j cDNA and were analyzed for expression of CD158j by flow cytometry (B). Jurkat T cells infected with WR vaccinia virus or CD158j + vaccinia virus were stimulated with anti-CD3 and/or anti-CD158b/j mAbs and cross-linked with rabbit anti–mouse IgG Ab. After SDS-PAGE and transfer to a nitrocellulose membrane, the cell lysates were analyzed for phosphorylation of JNK (top left panels) and MKK4 (bottom left panel). The blots were stripped and reprobed with Abs against β-actin (top right panels) or MKK4 (bottom right panel) (C).

Mutation of transmembrane lysine residue in CD158j abolishes ability to induce JNK phosphorylation. Jurkat T cells were transiently transfected with constructs containing the CD158j cDNA or the CD158j233I cDNA. Cell-surface expression was confirmed by flow cytometry (A). Jurkat T cells transfected with either CD158j or CD158jK233I were stimulated with anti-CD3 or anti-CD158b/j mAb and cross-linked with rabbit anti–mouse IgG Ab. After SDS-PAGE and transfer to a nitrocellulose membrane, the cell lysates were analyzed for phosphorylation of JNK (left panels). The blots were then stripped and reprobed with Abs against total JNK (right panels) (B).

CD158j and DAP10 do not associate. RT-PCR was used to amplify transcripts for DAP10 from PBMCs (lane 1) and CD4 + CD28 null T cell clones (lanes 2–5). cDNA was omitted for the negative control (lane 6) (A). CD4 + CD28 null CD158b/j + T cell clones were stimulated with anti-CD3 or anti-CD158b/j in the presence or absence of 2.0 μM wortmannin. After SDS-PAGE and transfer to a nitrocellulose membrane, the cell lysates were analyzed for phosphorylation of JNK (left panels). The blots were then stripped and reprobed with Abs against β-actin (right panels). Results from two T cell clones are shown (B). DAP10-expressing RBL cells (left panel) were stably transfected with CD158j alone (middle panel) or with CD158j and KARAP/DAP12 (right panel). Cell surface expression of CD158j was confirmed by flow cytometry (top panels). DAP10 or KARAP/DAP12 was immunoprecipitated from lysates of biotinylated transfected RBL cells. After SDS-PAGE and transfer to nitrocellulose membranes, coimmunoprecipitated cell-surface proteins were detected by streptavidin-HRP (middle panels). Immunoprecipitation of DAP10 and KARAP/DAP12 was confirmed by immunoblot with anti-DAP10 or anti-KARAP/DAP12 Ab (bottom panels) (C). DAP10 or KARAP/DAP12 was immunoprecipitated from Jurkat T cells (lanes 1–3) or RBL cells (lanes 4–6). After SDS-PAGE and transfer to a nitrocellulose membrane, samples (protein-G preclear, lanes 1 and 4; DAP10 immunoprecipitate, lanes 2 and 5; KARAP/DAP12 immunoprecipitate, lanes 3 and 6) were analyzed by Western blot using DAP10 Ab (D).
