Is LDN an immuno-suppressive drug?
LDN is best classified as an immuno-regulator. It causes an increase in OGF levels – and OGF regulates proliferation of all cells, including immune cells (T-cells and B-cells). When immune cells are being produced in excess (leading to autoimmune conditions), OGF acts to slow down their proliferation. Whilst this can be construed as immune-suppression, it is most accurately described as immune-regulation.
