Abstract:
Although deficiencies in the NKT cell population have been observed in multiple sclerosis and mouse strains susceptible to experimental autoimmune encephalomyelitis (EAE), little is known about the function of these cells in CNS autoimmunity. In this work we report that TCR Valpha14-Jalpha281 transgenic nonobese diabetic mice, which are enriched in CD1d-restricted NKT cells, are protected from EAE. The protection is associated with a striking inhibition of Ag-specific IFN-gamma production in the spleen, implying modulation of the encephalitogenic Th1 response. This modulation is independent of IL-4 because IL-4-deficient Valpha14-Jalpha281 mice are still protected against EAE and independent of NKT cell-driven Th1 to Th2 deviation, because no increased autoantigen-specific Th2 response was observed in immunized Valpha14-Jalpha281 transgenic mice. Our findings indicate that enrichment and/or stimulation of CD1d-dependent NKT cells may be used as a novel strategy to treat CNS autoimmunity.
Insights
Mice with more Natural Killer T (NKT) cells are protected from experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. This protection involves suppressing the immune response that causes the disease.
Area of Science:
- Immunology
- Neuroimmunology
- Autoimmunity
Background:
- Natural Killer T (NKT) cell deficiencies are linked to multiple sclerosis and experimental autoimmune encephalomyelitis (EAE).
- The precise function of NKT cells in central nervous system (CNS) autoimmunity remains largely uncharacterized.
Purpose of the Study:
- To investigate the role of CD1d-restricted NKT cells in preventing EAE.
- To explore the mechanisms underlying NKT cell-mediated protection against CNS autoimmunity.
Main Methods:
- Utilized TCR Valpha14-Jalpha281 transgenic nonobese diabetic mice, which exhibit an enrichment of CD1d-restricted NKT cells.
- Assessed EAE susceptibility and measured Ag-specific IFN-gamma production in spleen cells.
- Investigated the role of IL-4 and Th1/Th2 deviation in the protective mechanism.
Main Results:
- Transgenic mice enriched in NKT cells demonstrated significant protection against EAE development.
- Protection correlated with a marked inhibition of antigen-specific Interferon-gamma (IFN-gamma) production in the spleen.
- The protective effect was independent of Interleukin-4 (IL-4) and did not involve a shift from Th1 to Th2 immune responses.
Conclusions:
- Enrichment or stimulation of CD1d-dependent NKT cells offers a potential therapeutic strategy for CNS autoimmune diseases like multiple sclerosis.
- NKT cells modulate the encephalitogenic Th1 response, thereby preventing autoimmune neuroinflammation.
