Figure Lengend Snippet: Quantification of gene expression patterns of inflammatory and osteoclastogenic cytokines in purified CD4+ T cells in mice at 20 months of age. CD4+ T cells were immunomagnetically purified from spleens of 20-month-old wild-type (WT) C57BL6/J and T-cell-reconstituted TCRβ knockout (KO) mice (T cells) and subjected to NanoString mRNA gene quantification for common osteoclastogenic and inflammatory cytokines: (A) mRNA for downstream osteoclastogenic mediators (RANKL, osteoprotegerin, and the RANKL/osteoprotegerin ratio). (B) Inflammatory mediators of osteoclastogenesis (tumor necrosis factor [TNF]α and IL-1β) and (C) IL-17A and IL-6. Data are expressed as boxplots (median ± interquartile range) with 10 to 90 percentile whiskers: ∗P < .05 and ∗∗P < .01 by Mann-Whitney U test. Nonsignificant comparisons not shown. n = 5 WT and 7 T-cell mice/group.
Article Snippet: Expression of RANKL, OPG, TNFα, interleuking (IL)-1β, IL-17A, and IL-6 messenger ribonucleic acid (mRNA) was quantified from 50 000 immunomagnetically purified (StemCell Technologies) CD4 + T cells lysed directly in 1:3 RLT buffer (QIAGEN, Germantown, MD) and hybridized with gene-specific fluorescent barcoded probes at 65°C for 24 hours without RNA extraction.
