It has been widely shown that many plant-derived compounds present significant anti-inflammatory effects. For this reason, they represent potential molecules for the development of new drugs, especially designed for the treatment and/or control of chronic inflammatory states such as rheumatism, asthma, inflammatory bowel diseases, atherosclerosis, etc. This review focuses on the naturally-occurring compounds with anti-inflammatory properties and attempts to correlate their actions with the modulation of cytokines and associated intracellular signalling pathways; it continues the review published in the November, 2003 issue of Planta Medica.

The postnatal maturation of the gut, partially modulated by bacterial colonization, ends up in the establishment of an efficient barrier to luminal antigens and bacteria. The use of broad-spectrum antibiotics in pediatric practices alters the gut bacterial colonization and, consequently, may impair the maturation of the gut barrier function. To test this hypothesis, suckling Sprague-Dawley rats received a daily intragastric gavage of antibiotic (Clamoxyl; an amoxicillin-based commercial preparation) or saline solution from postnatal day 7 (d7) until d17 or d21. Luminal microbiota composition and global gene expression profile were analyzed on samples from small intestine and colon of each group. The treatment with Clamoxyl resulted in the almost-complete eradication of Lactobacillus in the whole intestine and in a drastic reduction of colonic total aerobic and anaerobic bacteria, in particular Enterobacteriacae and Enterococcus. The global gene expression analysis revealed that Clamoxyl affects the maturation process of 249 and 149 Affymetrix probe sets in the proximal and distal small intestine, respectively, and 163 probe sets in the colon. The expression of genes coding for Paneth cell products (defensins, matrilysin, and phospholipase A2) was significantly downregulated by the Clamoxyl treatment. A significant downregulation of major histocompatibility complex (MHC) class Ib and II genes, involved in antigen presentation, was also observed. Conversely, mast cell proteases expression was upregulated. These results suggest that early treatment with a large-spectrum antibiotic deeply affects the gut barrier function at the suckling-weaning interface, a period during which the gut is challenged by an array of novel food-borne antigens.

In this study, the gene expression patterns of peripheral blood leucocytes (PBL) from Japanese flounder Paralichthys olivaceus were analyzed during the course of monogenean parasite Neoheterobothrium hirame infection in order to select candidates for molecular biomarkers of infection. cDNA microarray analysis was performed to compare the gene expression patterns of PBL between infected and non-infected fishes. Among the 797 genes analyzed, 45 genes (5.6%) changed their expression levels. These genes included specific and non-specific immune-related genes (matrix metalloproteinase[MMP]-9, MMP-13, leukotriene B4 receptor, CD20 receptor, MHC [major histocompatibility complex] Class I, MHC Class II beta-chain, immunoglobulin light chain and immunoglobulin heavy chain). Significant up- and down-regulation of some unknown genes was also observed. Several candidates for infection-marker genes were selected for further study. These genes included MMP-9, MMP-13, leukotriene b4 receptor, CD20 receptor, immunoglobulin heavy chain, immunoglobulin light chain and unknown genes coded as B613, E25, LB3(8), WE2(3), WE8-18R and WF12-18R.
