Abstract EN
The neuropeptide alpha-melanocyte stimulating hormone (α-MSH) has an important role in modulating immunity and homeostasis.
The production of IFN-γ by effector T cells is suppressed by α-MSH, while TGF-β production is promoted in the same cells.
Such α-MSH-treated T cells have immune regulatory activity and suppress hypersensitivity, autoimmune diseases, and graft rejection.
Previous characterizations of the α-MSH-induced Treg cells showed that the cells are CD4+ T cells expressing the same levels of CD25 as effector T cells.
Therefore, we further analyzed the α-MSH-induced Treg cells for expression of effector and regulatory T-cell markers.
Also, we examined the potential for α-MSH-induced Treg cells to be from the effector T-cell population.
We found that the α-MSH-induced Treg cells are CD25+ CD4+ T cells that share similar surface markers as effector T cells, except that they express on their surface LAP.
Also, the α-MSH treatment augments FoxP3 message in the effector T cells, and α-MSH induction of regulatory activity was limited to the effector CD25+ T-cell population.
Therefore, α-MSH converts effector T cells into Treg cells, which suppress immunity targeting specific antigens and tissues.
