Epigenetic modification of the human CCR6 gene is associated with stable CCR6 expression in T cells.

CCR6 is a chemokine receptor expressed on Th17 cells and regulatory T cells that is induced by T-cell priming with certain cytokines, but how its expression and stability are regulated at the molecular level is largely unknown. Here, we identified and characterized a noncoding region of the human CCR6 locus that displayed unmethylated CpG motifs (differentially methylated region [DMR]) selectively in CCR6(+) lymphocytes. CCR6 expression on circulating CD4(+) T cells was stable on cytokine-induced proliferation but partially down-regulated on T-cell receptor stimulation.

Therapeutic potential of CAMPATH-1H in skeletal tumours.

Aims: CD 52 is a glycosylphosphatidylinositol (GPI)-anchored glycoprotein that is expressed abundantly on all lymphocytes, monocytes, macrophages, eosinophils and in the male genital tract. To date, the physiological role of CD52 on lymphocytes has not been elucidated. However, an antibody directed to CD52 called CAMPATH-1H has been shown to be capable of depleting lymphocytes.

Striptease on glass: validation of an improved stripping procedure for in situ microarrays.

Microarrays have rapidly become an indispensable tool for gene analysis. Microarray experiments can be cost prohibitive, however, largely due to the price of the arrays themselves. Whilst different methods for stripping filter arrays on membranes have been established, only very few protocols are published for thermal and chemical stripping of microarrays on glass.
