Invariant NKT cells limit activation of autoreactive CD1d-positive B cells
Faulty activation of autoreactive B cells is a hallmark of autoimmune diseases like systemic lupus erythematosus (SLE). An important feature restricting activation of autoreactive B cells is efficient removal of apoptotic material. Mounting evidence also connects a primary defect in invariant natural killer T (iNKT) cells to autoimmune disease development. However, exactly how this unconvention...
متن کاملInvariant NKT cells inhibit autoreactive B cells in a contact- and CD1d-dependent manner.
Autoantibody production is a hallmark of autoimmune diseases, such as lupus and rheumatoid arthritis. Accumulating evidence suggests a role of invariant NKT (iNKT) cells in their pathogenesis. Mechanisms underlying the role of iNKT cells in these diseases, however, remain unclear. In this study, we show that iNKT cells suppress IgG anti-DNA Ab and rheumatoid factor production and reduce IL-10-s...
متن کاملIMMUNOBIOLOGY CD4 engagement by CD1d potentiates activation of CD4 invariant NKT cells
The CD4 coreceptor is crucial in the activation of major histocompatibility complex (MHC) class II restricted CD4 T lymphocytes by binding the same MHC class as the T-cell receptor (TCR) and by potentiating TCR-dependent signaling. CD4 is also expressed by invariant natural killer T cells (iNKT), which recognize natural and synthetic lipid antigens, such as -galactosyl ceramide ( -GalCer), in a...
متن کاملCD4 engagement by CD1d potentiates activation of CD4+ invariant NKT cells.
The CD4 coreceptor is crucial in the activation of major histocompatibility complex (MHC) class II restricted CD4 (+) T lymphocytes by binding the same MHC class as the T-cell receptor (TCR) and by potentiating TCR-dependent signaling. CD4 is also expressed by invariant natural killer T cells (iNKT), which recognize natural and synthetic lipid antigens, such as alpha-galactosyl ceramide (alpha-...
متن کاملCD1d-dependent Activation of NKT Cells Aggravates Atherosclerosis
Adaptive and innate immunity have been implicated in the pathogenesis of atherosclerosis. Given their abundance in the lesion, lipids might be targets of the atherosclerosis-associated immune response. Natural killer T (NKT) cells can recognize lipid antigens presented by CD1 molecules. We have explored the role of CD1d-restricted NKT cells in atherosclerosis by using apolipoprotein E-deficient...
