Nickel antigen induces IL-2 secretion and IL-2 receptor expression mainly on CD4 super(+) T cells, but no measurable gamma interferon secretion in peripheral blood mononuclear cell cultures in delayed type hypersensitivity to nickel
Nickel sulphate antigen-induced peripheral blood lymphocyte activation in vitro was characterized by lymphokine measurement (IL-2, IFN- gamma ) and phenotyping of the IL-2 responsive cells. Mononuclear cells from nickel-sensitive patients synthesized more DNA, produced more IL-2 and had more IL-2 re...

Zusammenfassung: | Nickel sulphate antigen-induced peripheral blood lymphocyte activation in vitro was characterized by lymphokine measurement (IL-2, IFN- gamma ) and phenotyping of the IL-2 responsive cells. Mononuclear cells from nickel-sensitive patients synthesized more DNA, produced more IL-2 and had more IL-2 receptor positive cells in response to nickel than did those of the control subjects. On the other hand no IFN- gamma was detectable in the nickel supernatants, while PPD, used as the control antigen, induced pronounced quantities of IFN- gamma with an equal amount of DNA synthesis. In conclusion, nickel-induced peripheral blood mononuclear cell activation in vitro differs from microbial antigen-induced activation with respect to its modest or non-existent IFN- gamma response. |
