Effect of Trehalose Disaccharide on Activation of Microglia and Indices of Systemic Inflammation in an Experimental Model of Alzheimer's Disease.

In an experimental model of Alzheimer's disease in mice, oral administration of trehalose disaccharide reduces neuroinflammation assessed by the expression level of microglia activation marker Iba1 and affects the neutrophil degranulation activity. A potential anti-inflammatory effect of 4% trehalose solution associated with a decrease in the activity of leukocyte elastase in plasma was revealed.

Alimentary Treatment with Trehalose in a Pharmacological Model of Alzheimer's Disease in Mice: Effects of Different Dosages and Treatment Regimens.

In the treatment of experimental neurodegeneration with disaccharide trehalose, various regimens are used, predominantly a 2% solution, drunk for several weeks. We studied the effects of different regimens of dietary trehalose treatment in an amyloid-β (Aβ) 25-35-induced murine model of Alzheimer's disease (AD). Aβ-treated mice received 2% trehalose solution daily, 4% trehalose solution daily (continuous mode) or every other day (intermittent mode), to drink for two weeks.

Antitumor Effects of an Anthocyanin-Rich Grain Diet in a Mouse Model of Lewis Lung Carcinoma.

Functional foods enriched with plant polyphenol anthocyanins attract particular attention due to their health-promoting properties, including antitumor activity. We evaluated the effects of a grain diet rich in anthocyanins in a mouse model of Lewis lung carcinoma. Mice of the C57BL/6 strain were fed with wheat of near-isogenic lines differing in the anthocyanin content for four months prior to tumor transplantation.

Hepatotropic activity of a betulonic acid based compound.

Using the model of cyclophosphamide (CP)-induced immunosuppression in C57BL/6 mice, the hepatotropic effects of a conjugate of betulonic acid with 9-(4-methylpiperazin-1-ylmethyl)-2-(1,2,3-triazolyl) oreozelone (BABC) have been studied. In the liver of treated animals the expression of genes for cytochromes (CYP 1A1, CYP 1A2, CYP 3A44, CYP 2B10, CYP 2C29, CYP 17A1), PPARA, and cytokines (TNF-α, IL-1β, IL-12α, IL-10) and the relative levels of NF-κB p65, GST-π, and NAT-1 proteins were determined. On day six after administration of the compound and CP to animals a significant (3.
