“Allogeneic hematopoietic cell transplantation (HCT) is widely used to treat patients with life-threatening malignant and nonmalignant hematological diseases. However, allogeneic HCT often is accompanied by severe and lethal complications from graft-versus-host disease (GVHD)…
Cannabinoids, the active ingredients found in Cannabis sativa, have been shown to exhibit a wide range of pharmacological properties. Studies from our laboratory and elsewhere have suggested that cannabinoids exhibit potent anti-inflammatory properties and therefore can be used to treat autoimmune and inflammatory diseases.
Cannabinoids have been shown to inhibit tumor cell growth and angiogenesis, suggesting their potential use in the treatment of gliomas, prostate and breast cancers, and malignancies of immune origin.
Δ9-Tetrahydrocannabinol (THC) is one of the most extensively investigated ingredients found in cannabis. THC activates both CB1 and CB2, thereby mediating both psychotropic and anti-inflammatory properties.
Inasmuch as our previous studies suggested that THC exhibits anti-inflammatory and immunosuppressive properties, we tested the possibility of its use in treating GVHD in a parent → F1 model. We hereby demonstrate for the first time that administration of THC during allogeneic transplantation can significantly suppress GVHD…
Our results demonstrate for the first time that targeting cannabinoid receptors may constitute a novel treatment modality against acute GVHD.”
