Methylprednisolone (MP) has been recommended as a standard drug in MS therapies. We previously demonstrated that IFNβ-secreting human bone marrow-derived mesenchymal stem cells (MSCs-IFNβ) exert immunomodulatory effects in experimental autoimmune encephalomyelitic (EAE) mice. In this study, we evaluated whether a combined treatment of MP and MSCs-IFNβ had enhanced therapeutic effects on EAE mic...

The intake of probiotics has been associated with beneficial effects on the immune system, such as improved disease resistance and diminished risk of allergies. This review gives an overview of the immunomodulatory effects of probiotics investigated with in vitro assays, experimental animal models, and clinical trials, and explores possible mechanisms underlying the immunomodulatory effects. Im...

BACKGROUND AND OBJECTIVES Cladribine is a cytotoxic drug which ameliorates the clinical course of relapsing-remitting multiple sclerosis. In addition to cytotoxicity, the mode of action may include immunomodulatory mechanisms. This in vitro study was designed to investigate cladribine's effects on cell function after the removal of cladribine to distinguish cytotoxic versus immunomodulatory eff...

introduction: currently, developing new antibacterial drugs as alternative antibiotics is a very active area of research, due to widspreading widespread prevalence of resistant strains of microorganisms. this work intends to investigate of antibacterial properties and influence on immune blood cells of the silver-based compound hexamethylenetetramine (methenamine) silver nitrate with general fo...

Host defense peptides (often called cationic antimicrobial peptides) have pleiotropic immunomodulatory functions. The human host defense peptide LL-37 is up-regulated at sites of infection and has little or no antimicrobial activity in tissue-culture media but under the same conditions, demonstrates immunomodulatory effects on epithelial cells, monocytes, and dendritic cells (DC). These effects...

Poultry is known to be a major reservoir of Salmonella. The use of lactic acid bacteria has become one of successful strategies to control Salmonella in poultry. The purpose of this study was to select lactic acid bacteria strains by their in vitro immunomodulatory properties for potential use as probiotics against Salmonella infection in broiler chicks. Among 101 isolated lactic acid bacteria ...

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, ...

Macrolides, a class of antimicrobials isolated from Streptomycetes more than 50 years ago, are used extensively to treat sinopulmonary infections in humans. In addition, a growing body of experimental and clinical evidence indicates that long-term (years), low (sub-antimicrobial)-dose 14- and 15-membered ring macrolide antibiotics, such as erythromycin, clarithromycin, roxithromycin and azithro...

The immunomodulatory function of longan pulp polysaccharide-protein complex (LP3) was investigated in immunosuppressed mice models. Compared with the model control, peroral administration of 100 mgkg⁻¹d⁻¹ LP3 could significantly increase/enhance antibody production against chicken red blood cell (CRBC), concanavalin A (ConA)-induced splenocyte proliferation, macrophage phagocytosis, NK cell cyt...

Lenalidomide and the immunomodulatory drugs stand as prime examples of potentially dangerous chemical com...
