The immunomodulatory activity of mesenchymal stem/stromal cells (MSCs) to suppress innate and adaptive immune responses offers a potent cell therapy for modulating inflammation and promoting tissue regeneration. However, the inflammatory cytokine milieu plays a critical role in stimulating MSC immunomodulatory activity. In particular, interferon-γ (IFN-γ)-induced expression of indoleamine 2,3-d...

Introduction. Immunomodulatory drugs (IMiDs) are a class of chemical derivatives thalidomide with numerous immunomodulatory, antiangiogenic, anti-inflammatory, and cytostatic effects in multiple myeloma (MM). Aim — to highlight the history discovery IMiDs discuss molecular mechanisms their therapeutic activity. Basic information. In 2010, more than half century after German company Chemie Grüne...

Bone marrow mesenchymal stem cells (BMMSCs) are capable of differentiating into multiple cell types and regulating immune cell response. However, the mechanisms that govern the immunomodulatory properties of BMMSCs are still not fully elucidated. Here we show that telomerase-deficient BMMSCs lose their capacity to inhibit T cells and ameliorate the disease phenotype in systemic sclerosis mice. ...

Flavonoids are potentially immunomodulatory factors and it may be inferred that these phytochemicals contribute to immunomodulatory properties of the Allium family. In the present study, we investigated the potential mechanism underlying the immunomodulatory effect of shallot and its ethyl acetate (EA) fraction as flavonoid-rich sources. Ex vivo, effects of a hydroalcoholic extract of shallot, ...

objective: the immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. materials and method: the essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. the essential oils were tested for hypersensitivity and hemagglutination reaction...
