background: salvia mirzayanii, a native plant to iran, is shown to have immunomodulatory effects on lymphocyte proliferation. objective: to identify the bioactive immunomodulatory compound(s) present in s. mirzayanii. methods: the crude extract was fractionated to five fractions in two steps using different solvents. the fractions were subjected to bioassay-guided fractionation. all the fractio...

Mesenchymal stem cells (MSC) are under development as an immunomodulatory therapy. The anticipated immunomodulatory effects of MSC are broad, from direct inhibition of lymphocyte proliferation, induction of regulatory T and B cells, to resetting the immune system via a hit-and-run principle. There are endless flavors of MSC. Differences between MSC are originating from donors variation, differe...

cancer immunotherapy (passive or active) involves treatments which promote the ability of the immune system to fight tumor cells. several types of immunotherapeutic agents, such as monoclonal antibodies, immune checkpoint inhibitors, non-specific immunomodulatory agents, and cancer vaccines are currently under intensive investigation in preclinical and clinical trials. cancer vaccines induce pe...

multiple sclerosis (ms) and its animal model, experimental autoimmune encephalomyelitis (eae), are chronic inflammatory demyelinating disorders of central nervous system (cns). while the cause is unclear, the fundamental mechanism is thought to be destruction of myelin sheaths of neurons through immune system. one of the approaches being proposed in eae therapy is neural stem cells (nscs) trans...
