The novel finding is that when THC and CBD are administered in combination (1:1), at a concentration of 10 μM:10 μM, the phytocannabinoids are effective inhibitors of TLR3 induction of the chemokine CXCL10 and type I IFN-β, in PBMCs from both MS and control cohorts. The gene discussed is CXCL10; the disease is myeloid sarcoma.
