Anti-inflammatory function of arctiin by inhibiting COX-2 expression via NF-κB pathways.

Background: Arctiin, isolated from Forsythia suspensa has been reported to have anti-inflammatory, anti-oxidant, antibacterial, and antiviral effects in vitro. However, there has been a lack of studies regarding its effects on immunological activity. The aim of this study is to investigate the anti-inflammatory potential and possible mechanisms of arctiin in LPS-induced macrophages.

Dietary Aloe Improves Insulin Sensitivity via the Suppression of Obesity-induced Inflammation in Obese Mice.

Background: Insulin resistance is an integral feature of metabolic syndromes, including obesity, hyperglycemia, and hyperlipidemia. In this study, we evaluated whether the aloe component could reduce obesity-induced inflammation and the occurrence of metabolic disorders such as blood glucose and insulin resistance.

Methods: Male C57BL/6 obese mice fed a high-fat diet for 54 days received a supplement of aloe formula (PAG, ALS, Aloe QDM, and Aloe QDM complex) or pioglitazone (PGZ) and were compared with unsupplemented controls (high-fat diet; HFD) or mice fed a regular diet (RD).

Hypoglycemic and hypolipidemic effects of processed Aloe vera gel in a mouse model of non-insulin-dependent diabetes mellitus.

The effects of processed Aloe vera gel (PAG) on the course of established diet-induced non-insulin-dependent diabetes mellitus (NIDDM) were studied in C57BL/6J mice. NIDDM was induced in C57BL/6J mice by feeding them a high-fat diet. Mice exhibiting diet-induced obesity (DIO) with blood glucose levels above 180mg/dl were selected to examine the antidiabetic effects of PAG.

Auranofin, an immunosuppressive drug, inhibits MHC class I and MHC class II pathways of antigen presentation in dendritic cells.

Auranofin (AF), an orally administered, gold-based, anti-arthritic agent, has emerged as a clinically useful therapeutic drug for the treatment of rheumatoid arthritis. In the present study, we examined the effects of AF on major histocompatibility complex (MHC)-restricted antigen presentation in dendritic cells (DCs), which are the most important accessory cells for the induction of T cell responses. A mouse dendritic cell line, DC2.

Auranofin inhibits overproduction of pro-inflammatory cytokines, cyclooxygenase expression and PGE2 production in macrophages.

Auranofin (AF), a gold compound, is an orally active therapeutic agent used to treat rheumatoid arthritis (RA), a self-perpetuating inflammatory disease. RA is characterized by autoimmune-mediated proliferation of synovial cells that leads to inflammation, pain, and swelling in most major joints: However, the mechanism as to how AF relieves RA symptoms has not been fully elucidated. The object of this study was to examine the ability of AF to immunomodulate macrophages as antigen presenting cells (APCs).

Effects of mizoribine on MHC-restricted exogenous antigen presentation in dendritic cells.

Mizoribine (MZR) has been shown to possess immunosuppressive activity that selectively inhibits the proliferation of lymphocytes by interfering with inosine monophosphate dehydrogenase. The efficacy of MZR is not only in patients who have had renal transplantation, but also in patients with rheumatoid arthritis (RA), lupus nephritis, and primary nephritic syndrome. Because the exact mechanism of its immunosuppressive action is not clear, the object of this study was to examine the ability of MZR to regulate the antigen presenting cells (APCs), dendritic cells (DCs).
