Abstract
Systemic inflammation caused by infection, surgery, or injury can lead to cognitive decline. Lipopolysaccharides are known as toll-like receptor 4 ligands, which are common to the cell walls of gram-negative bacteria. Activation of toll-like receptor 4 leads to the production of proinflammatory cytokines that subsequently mediate systemic inflammation. Furthermore, induc¬tion of systemic inflammation by lipopolysaccharide injection in mice can affect the brain, including cognitive functions. To investigate the neuroprotective role of gossypetin in systemic inflammation, a mouse hippocampal cell line (HT22) and mice were challenged with lipopolysaccharide. The increase in proinflammatory cytokines and reactive oxygen species caused by lipopolysaccharide treatment in HT22 cells was decreased by gossypetin treatment. To evaluate the protective function against memory impairment, gossypetin was orally administered to C57BL/6J mice receiving lipopolysaccharide injec¬tion. Lipopolysaccharide-induced memory deficit was observed in lipopolysaccharide-only treated group in Y-maze test. However, the group treated with gossypetin and lipopolysaccharide had a diminution in cognitive impairment. Consistent with the behavioral test results, the proinflammatory cytokines were also relatively downregulated in the gossypetin-treated mouse group. To sum up, gossypetin can be protect the neuron cells from inflammation in vitro and prevent the cognitive impairment in mice in vivo.
期刊介绍:
Current Topics in Nutraceutical Research is an international, interdisciplinary broad-based peer reviewed scientific journal for critical evaluation of research on chemistry, biology and therapeutic applications of nutraceuticals and functional foods. The major goal of this journal is to provide peer reviewed unbiased scientific data to the decision makers in the nutraceutical and food industry to help make informed choices about development of new products.
To this end, the journal will publish two types of review articles. First, a review of preclinical research data coming largely from animal, cell culture and other experimental models. Such data will provide basis for future product development and/or human research initiatives. Second, a critical evaluation of current human experimental data to help market and deliver the product for medically proven use. This journal will also serve as a forum for nutritionists, internists, neurologists, psychiatrists, and all those interested in preventive medicine.
The common denominator of all of the topic to be covered by the journal must include nutraceuticals and/functional food. The following is an example of some specific areas that may be of interest to the journal. i) Role of vitamins, minerals, antioxidants and phytonutrients on cardiovascular health, cancer, diabetes, ocular health, mental health, men’s health, women’s health, infant nutrition, ii) Role of herbals on human health, iii) Dietary supplements and sleep, iv) Components of diet that may have beneficial effect on human health, v) regulation of apoptosis and cell viability, vi) Isolation and characterization of bioactive components from functional foods, vii) Nutritional genomics, and viii) Nutritional proteomics.
