Oligonol, a lychee fruit-derived low-molecular form of polyphenol mixture, suppresses inflammatory cytokine production from human monocytes.

Monocytes produce high levels of inflammatory cytokines including IL-6 and TNF-α that are involved in autoimmunity, inflammatory diseases, cardiovascular disease and obesity. Therapies targeting IL-6 and TNF-α have been utilized in treating chronic inflammatory diseases. Oligonol is a lychee fruit-derived low-molecular form of polyphenol mixture, typically catechin-type monomers and oligomers of proanthocyanidins, which are produced by an oligomerization process.

DNA Methylation Regulates the Differential Expression of CX3CR1 on Human IL-7Rαlow and IL-7Rαhigh Effector Memory CD8+ T Cells with Distinct Migratory Capacities to the Fractalkine.

DNA methylation is an epigenetic mechanism that modulates gene expression in mammalian cells including T cells. Memory T cells are heterogeneous populations. Human effector memory (EM) CD8(+) T cells in peripheral blood contain two cell subsets with distinct traits that express low and high levels of the IL-7Rα.

Helicobacter pylori Associated Lymphocytic Gastritis in a Child.

Lymphocytic gastritis (LG) is a rare subtype of chronic gastritis. It is defined as dense proliferation of intraepithelial lymphocytes (IELs) more than 25 lymphocytes per 100 epithelial cells. The known major causes of LG are celiac disease and Helicobacter pylori infection.
