Amelioration of Experimental Autoimmune Encephalomyelitis by β
... IL-17 was reduced in spinal cord in β-elemene-treated mice, whereas higher expression of IL-17 was seen in spinal cord in sham-treated mice similar during the early stage of EAE. These results suggested that β-elemene inhibits EAE by inhibiting Th17 cell proliferation in spinal cord of the EAE mice. ...

Lymphopoiesis
Lymphopoiesis (lĭm'fō-poi-ē'sĭs) (or lymphocytopoiesis) is the generation of lymphocytes, one of the five types of white blood cell (WBC). It is more formally known as lymphoid hematopoiesis.Pathosis in lymphopoiesis leads to any of various lymphoproliferative disorders, such as the lymphomas and lymphoid leukemias.
