Alpha s1-casein-specific CD8+ T cell clone that inhibits its own interferon-gamma production by producing interleukin-10.
A CD8+ T cell clone specific to alpha s1-casein, one of the major allergens in milk, is shown to inhibit its own production of interferon (IFN)-gamma by producing interleukin (IL)-10. Anti-IL-10 antibodies enhanced the production of IFN-gamma induced by the antigen plus antigen-presenting cells from 12 h onward after initiating the culture. This enhancing effect was observed only when the cells were stimulated in the presence of the antigen-presenting cells. Neither IL-2 nor IL-4 abrogated this enhancing effect. This reveals a new regulating mechanism for IFN-gamma production from CD8+ T cells.
