A role for Lyn kinase as a positive regulator of immunoglobulin (Ig)E-dependent allergy has long been accepted. Contrary to this belief, Lyn kinase was found to have an important role as a negative regulator of the allergic response. This became apparent from the hyperresponsive degranulation of lyn-/- bone marrow-derived mast cells, which is driven by(More)
The linker for activation of T cells (LAT) is an adaptor protein critical for Fc ␧ RI-mediated mast cell activation. LAT is a substrate of the tyrosine kinases activated after TCR and Fc ␧ RI engagement. After phosphorylation of the cytosolic domain of LAT, multiple signaling molecules such as phospholipase C– ␥ 1, Grb2, and Gads associate with(More)
Mast cell degranulation and de novo cytokine production is a consequence of antigen-aggregation of the immunoglobulin E (IgE)-occupied high affinity receptor for IgE (Fc epsilon RI). Herein, we report that lymphokines that promote allergic inflammation, like MCP-1, were potently induced at low antigen (Ag) concentrations or at low receptor occupancy with(More)
Mutation of the 3beta-hydroxysterol delta7-reductase gene (Dhcr7-/-) results in Smith-Lemli-Opitz syndrome (SLOS). Patients, and genetically altered mice, are unable to produce cholesterol and accumulate 7-dehydrocholesterol (DHC) in serum and tissue. This causes multiple growth and developmental abnormalities as well as immune system anomalies including(More)
