Both vitamin A and D up - regulate expression of a population of immune cells known as toleragenic FoxP3 + regulatory T cells (Tregs), which engender balance between the Th1, Th2, or Th17 arms of the immune system, all of which can perpetuate autoimmunity when their exquisitely fine - tuned balance is disrupted.

Although investigators have not yet identified which cells carry Sema4a in tumors and boost regulatory T cell function, the scientists did report that immune cells called plasmacytoid dendritic cells (pDCs) provided more than half of the Sema4a in tumors in this study.

The other, neuropilin - 1 (Nrp1), is carried on the surface of regulatory T cells.

«That is significant because mice and humans that lack or have substantial defects in regulatory T cells develop lethal autoimmune disease,» Vignali said.

The work focused on white blood cells called regulatory T cells.

Knocking out or blocking the activity of Nrp1 on regulatory T cells in mouse models of several human cancers, including the deadly skin cancer melanoma, led to reduced, delayed or complete elimination of the tumors.

When scientists eliminated Nrp1 on just regulatory T cells, those cells were unable to respond to signals that normally bolstered their anti-inflammatory activity.

Vignali and his colleagues used a variety of molecular and cellular techniques to show that Sema4a binding to Nrp1 turns on a biochemical pathway in mouse regulatory T cells that enhances their function, stability and survival.

Researchers also provided new details of how the Nrp1 pathway functions, including evidence that along with bolstering the ability of regulatory T cells to suppress the immune response, the pathway also helps maintain a stable population of regulatory T cells.

Moreover IL - 7 reduces the suppressive activity of regulatory T cells.

In this study, investigators identified a mechanism that boosts the ability of regulatory T cells to cause problems by blocking an effective anti-tumor immune response.

«Mice lacking Nrp1 on regulatory T cells were almost completely resistant to developing melanoma, but did not develop any autoimmune or inflammatory complications.»

When investigators analyzed human regulatory T cells, they found evidence that the pathway may also serve the same role.

«We have identified a mechanism that enhances the ability of regulatory T cells to put the brakes on the immune response in tumors but plays no role in immune system maintenance.
