Abstract

Cell-mediated (type-1) immunity is necessary for immune protection against most intracellular pathogens and, when excessive, can mediate organ-specific autoimmune destruction. Mice deficient in Eta-1 (also called osteopontin) gene expression have severely impaired type-1 immunity to viral infection [herpes simplex virus–type 1 (KOS strain)] and bacterial infection ( Listeria monocytogenes ) and do not develop sarcoid-type granulomas. Interleukin-12 (IL-12) and interferon-γ production is diminished, and IL-10 production is increased. A phosphorylation-dependent interaction between the amino-terminal portion of Eta-1 and its integrin receptor stimulated IL-12 expression, whereas a phosphorylation-independent interaction with CD44 inhibited IL-10 expression. These findings identify Eta-1 as a key cytokine that sets the stage for efficient type-1 immune responses through differential regulation of macrophage IL-12 and IL-10 cytokine expression.

  22. C57BL/6 × 129/SV Eta-1 −/− mice generated as described by S. R. Rittling et al. [ J. Bone Miner. Res. 13 1101 (1998)] were compared to either Eta-1 +/+ littermates or age-matched C57BL/6 × 129/SV mice as controls.
  23. T and B cell subsets in Eta-1 −/− and Eta-1 +/+ littermates were as follows: C57BL/6 × 129 Eta-1 +/+ spleen 93.7 × 10 6 total cells (30.8% CD3 19.8% CD4 11% CD8 and 49.7% B220); C57BL/6 × 129 Eta-1 −/− spleen 82.6 × 10 6 cells (27.8% CD3 18.8% CD4 9.0% CD8 and 55.5% B220); C57BL/6 × 129 Eta-1 +/+ lymph node 32.0 × 10 6 cells (82.4% CD3 42.8% CD4 34.2% CD8 and 12.8% B220); and C57BL/6 × 129 Eta-1 −/− lymph node 21.9 × 10 6 cells (82.8% CD3 49.3% CD4 28.4% CD8 and 11.2% B220). T cells from Eta-1 −/− and Eta-1 +/+ mice expressed levels of CD44 and CD62 that were not distinguishable. T cell expansion followed by apoptosis after superantigen (50 μg of staphylococcal enterotoxin B) intraperitoneal injection into Eta-1 −/− and Eta-1 +/+ mice was indistinguishable at 3 days: +/+ V β 8 + CD4 cells (percentage of total spleen) increased from 3.6 to 5%; −/− V β 8 + CD4 cells increased from 3.2 to 5.5%; +/+ V β 6 + CD4 cells increased from 2.3 to 2.6%; −/− V β 6 + CD4 cells increased from 2.5 to 2.6%. Expression of IL-2 by lymph node and spleen T lymphocytes from Eta-1 −/− and Eta-1 +/+ littermates in response to immobilized antibody to CD3 was also indistinguishable between the C57BL/6 × 129/SV Eta-1 −/− and C57BL/6 × 129/SV Eta-1 +/+ mice.

  29. . 19. HSV-1 stimulation of lymph node cells and splenic macrophages: The right superficial cervical draining lymph nodes of Eta-1 −/− mice and Eta-1 +/+ littermate controls were harvested 15 days after infection of the right eye with 4 × 10 6 PFU of HSV-1 (KOS). Cells from these lymph nodes (2 × 10 6 cells per well) were incubated in the presence of 4 × 10 7 PFU of ultraviolet (UV)–inactivated HSV-1 (KOS). Supernatants harvested 48 hours later were tested for IL-10 and IL-12 p40 cytokine by sandwich enzyme-linked immunosorbent assay (ELISA) using OptEIA antibody sets (PharMingen La Jolla CA). IL-4 was measured after stimulation of draining lymph node cells by plate-bound antibody to CD3.

  36. Listeria infection and cytokine production were as followed. Virulent L. monocytogenes [strain 1778 American Type Culture Collection (ATCC) designation 43251] was grown in trypticase soy broth (Becton-Dickinson) and 10 3 colony-forming units (CFU) a sublethal dose for this strain of L. monocytogenes were injected intravenously . The titer of viable bacteria in the inoculum and in organ homogenates was determined by plating 10-fold serial dilutions on trypticase soy agar plates. Eta-1 −/− mice contained liver-associated Listeria -infected cysts that were apparent 4 to 5 days after infection. Plates were incubated at 37°C and the numbers of CFU were counted after 24 hours.
  37. Spleen cells (4 × 10 6 /ml) from four to five C57BL/6 × 129 Eta-1 +/+ or four to five C57BL/6 × 129 Eta-1 −/− mice that had been intravenously inoculated 5 days earlier with 10 3 CFU were stimulated with heat-killed L. monocytogenes (2 × 10 8 CFU/ml) 96 hours before IFN-γ measurement by an OptEIA ELISA kit (PharMingen).

  52. Dephosphorylation of Eta-1 is as follows. Five milligrams of purified Eta-1 was dephosphorylated using 6 U (60 U/mg) of type-II potato acid phosphatase (Sigma) as described (39). Phosphorylation of recombinant Eta-1:glutathione S -transferase (GST)–Eta-1 (5 mg) was phosphorylated as described [
  53. 10.1111/j.1749-6632.1995.tb44639.x
  54. ; (27)]. Phospho–amino acid analysis of the recovered protein revealed a phosphoserine content of 16 mol of phosphate per 1 mol of protein and 0.8 mol of phosphothreonine per 1 mol of protein.

  60. PVP-dependent granulomas were formed as follows. C57BL/6 (+/+) C57BL/6 nu / nu C57BL/6–IL-12 −/− C57BL/6 × 129 Eta-1 +/+ and C57BL/6 ×129 Eta-1 −/− mice were injected subcutaneously above the right hind limb with 500 μl of 0.5% PVP; C57BL/6 nu / nu and Eta-1 −/− mice were coinjected with this inoculum of PVP and 10 μg of Eta-1 and purified as described below. After 5 days mice were killed tissue was extracted for histologic analysis and local lymph nodes were obtained for cytokine expression. Samples were fixed in 10% buffered formalin and embedded in paraffin; 4- to 5-μm serial sections were stained with hematoxylin and eosin and images were captured with a Sony DXC-970MD video camera and Optima 5.2 Histomorphometric analysis software.

  62. Recombinant GST–Eta-1 fusion protein derived from Escherichia coli was digested with factor Xa and purified by affinity chromatography [

  64. ; (39)]. Briefly native Eta-1 was isolated from MC3T3E1 cells or Ar5v T cells after concentration in PBS using a Millipore tangential flow system applied to a Millipore LC100 equipped with a DEAE-Memsep 1000 cartridge and developed in a discontinuous gradient of 0 to 1 M NaCl in phosphate buffer (pH 7.4). Eta-1–containing fractions were pooled (the major Eta-1 peak eluted at 0.26 M salt) concentrated by ultrafiltration chromatofocused on mono P columns (Pharmacia) at pH 8.2 developed with polybuffer 74 (Pharmacia) and eluted from monobeads at pH 4.6. The eluted protein was judged to be pure by several criteria including SDS electrophoresis and amino acid sequence analysis (NH 2 -terminal and internal peptide analysis). Mass spectroscopic analysis revealed a peak centered around a mass of 35 400 daltons that was highly phosphorylated (11 mol of phosphate per 1 mol of protein) O-glycosylated but not N-glycosylated and without measurable sulfate.
  65. Resident peritoneal macrophages obtained by peritoneal lavage with phosphate-buffered saline (PBS) were treated with red cell lysis buffer and incubated (10 5 macrophages per 100 μl) for 2 hours. The adherent fraction was incubated with 5 nM Eta-1 LPS (30 ng/ml) or recombinant IL-4 (500 U/ml) or as indicated. Supernatant IL-10 or IL-12 p70 was assayed with commercial ELISA kits (R&D Systems Minneapolis MN) tested for viability by propidium iodide (>98%) and stained with fluorescein-conjugated antibody to Mac-1 (>98%). Blocking antibody to integrin β 3 was from PharMingen [
  66. 10.1074/jbc.270.19.11522
  67. ] and antibody to CD44 KM81 (ATCC) was used to block the interaction between CD44 and Eta-1 (16).
  68. Although partial tryptic chemotryptic or Asp-N endopeptidase digestion of Eta-1 did not reveal an active peptide a 10-kD fragment isolated from a Lys-C digest [NH 2 -terminal sequence QETLPSN (29)] was active and predicted to terminate at the thrombin cleavage site. This 10-kD fragment contained ∼5 mol of phosphate per 1 mol of peptide at seven potential phosphorylation sites.
