Filifolinol is a natural occurring spirodihydrobenzofuran isolated from the resinous exudates of Heliotropium filifolium, a Chilean endemic shrub. Filifolinol and some of its derivatives have shown interesting biological ...

The role of glucan as a biologically active immunomodulator has been well documented for more than 40 years. However, the wide diversity of β-glucan forms and the extraction process has implications for the benefits of ...

The intestinal ecosystem contains a normal microbiota, non-immune cells and immune cells associated with the intestinal mucosa. The mechanisms involved in the modulation of the gut immune system by probiotics are not yet ...

Dietary immunomodulators can help to defend against disease, but their dosage and time of administration are not always clear in aquaculture. In this study, we analyzed the amount of dietary levamisole required to induce ...

The use of immunomodulators is an alternative to improve the immune system of fish and avoid the excessive use of antibiotics. Levamisole is a synthetic anthelmintic which promotes a potent immunostimulation on innate and ...
