Figure Lengend Snippet: Interleukin (IL)-7 promotes differentiation toward memory and effector T cells and cytokine-secreting T-helper cells . The number of naive CD4 T cells (CD44-CD62L + ) was not significantly altered by IL-7. By contrast, a significant increase in central memory (CD44 + CD62L + ) and effector memory (CD44 + CD62L - ) T cells was found after IL-7 administration (A) . IL-7 enhances numbers (and percentages) of CD4 T cells, and of Th1 (interferon (IFN)-g)-, and Th17 (IL-17)-, and Th2 (IL-4)-cytokine-secreting CD4 T cells (B) . Increased IFN-g was measured in supernatants from lymph node cells (LNs) of the IL-7-treated mice as compared with those of the PBS-treated mice. Moreover, on collagen type II (CII) restimulation of LNs, increased IL-17 and reduced IL-4 concentrations were measured, as compared with those of PBS-treated mice (C) . Statistical differences with PBS group of * P < 0.05, ** P < 0.01, and *** P < 0.001.
Article Snippet: For flow-cytometric analysis, monoclonal antibodies were used: anti-CD4 allophycocyanin (APC)/Cy7 (clone-Gk1.5; BD), anti-CD8 Pacific Blue (PB) (clone-53-6.7; BD), anti-CD19 peridinin-chlorophyll-protein (PerCP)/Cy5.5 (clone-1D3; BD), anti-CD44 FITC (clone-IM7; eBioscience, San Diego, CA, USA), and anti-CD62L APC (clone-mel-14; BD).
