Background: The purpose of the present study was to evaluate the effect of carotenoid astaxanthin (ASTA) on human neutrophils treated with high glucose and free fatty acids (FFA) on the phagocytic capacity and reactive oxygen/nitrogen species production. Methods: The following parameters were evaluated: phagocytic capacity of neutrophils by using zymosan particles, intracellular and extracellular superoxide anion (lucigenin and DHE probes), hydrogen peroxide (H(2)O(2) - phenol red), nitric oxide (Griess reagent) production, and maximal activity of G6PDH. Results: There was a decreased phagocytic capacity of human neutrophils treated with high glucose (30 mM) or FFA (01 mM) and a partial restoring of the phagocytic capacity after ASTA-treatment was observed. ROS and RNS production was increased in neutrophils due to both high glucose and FFA. This increase in ROS/RNS production was also partially prevented by ASTA treatment. Both glucose and FFA increased the G6PDH activity. We show that ASTA provides a modest improvement of cellular functions after cells have been treated with high glucose and FFA. Conclusions: In summary, this study showed that both high glucose and a mixture of FFA are potent inducers of ROS/RNS production on neutrophils as observed by higher levels of superoxide anion, hydrogen peroxide and NO(-) production. Also, these metabolites decrease the phagocytic capacity of neutrophils and increase the G6PDH activity. Overall, ASTA-treatment was able to reduce partially ROS/RNS production by reducing the availability of NADPH and recover phagocytic capacity of neutrophils. (C) 2011 Elsevier B.V.

Summary: This study aims to investigate the immune cell population in the subcutaneous and epididymal white adipose tissue (WAT) of obese mice, as well as the effects of green tea. The results suggest that a high-fat diet and thermoneutrality can induce chronic inflammation and insulin resistance. However, green tea can prevent weight gain, inflammation, and tissue fibrosis, while maintaining a similar immune cell profile to that of lean mice.

Mesenchymal stem cells attenuate systemic lupus erythematosus by inhibiting NLRP3 inflammasome activation through Pim-1 kinase

Honghong Yu, Qi Li, Huimin Zhu, Chang Liu, Weiwei Chen, Lingyun Sun

Summary: The activation of the inflammasome plays a critical role in the pathogenesis of systemic lupus erythematosus (SLE), and mesenchymal stem cells (MSC) have been shown to alleviate SLE by suppressing inflammasome activation. This study found that the NLRP3 inflammasome was activated in macrophages from SLE patients and mice, and its activation correlated with disease activity. After MSC transplantation, the severity of SLE was reduced, and NLRP3 inflammasome activation was inhibited. These findings suggest that MSC suppress inflammasome activation and provide a potential therapeutic target for SLE.
