TI  - SLP-76 deficiency impairs signaling via the high-affinity IgE receptor in mast
      cells.
PG  - 1737-43
AB  - SLP-76 is an adapter protein expressed in T cells and myeloid cells that is a
      substrate for ZAP-70 and Syk. SLP-76-deficient mice exhibit a profound block in
      T-cell development. We found that although SLP-76 is expressed in mouse mast
      cells, SLP-76(-/-) mice have normal numbers of mast cells in their skin and
      bronchi. SLP-76(-/-) mice are resistant to IgE-mediated passive anaphylaxis.
      SLP-76(-/-) mice sensitized with IgE anti-dinitrophenyl (DNP) and then challenged
      with DNP-HSA developed only mild and transient tachycardia, failed to increase
      their plasma histamine level, and all survived the antigen challenge. Bone
      marrow-derived mast cells (BMMCs) from SLP76(-/-) mice failed to release
      beta-hexosaminidase and to secrete IL-6 after FcepsilonRI cross-linking. Tyrosine
      phosphorylation of phospholipase C-gamma1 (but not of Syk) and calcium
      mobilization in response to IgE cross-linking were reduced in SLP-76-deficient
      BMMCs. These results suggest that SLP-76 plays an important role in
      FcepsilonRI-mediated signaling in mast cells.
