FIGURE 1.
Human T lymphocytes cultured in IL-2 have an effector cell Th1 phenotype and express CXCR3. FACS analysis of 14-day T lymphocytes shows no primary Ab (A), secondary goat anti-mouse immunoglobulins: alexa-488 alone (B); mouse mAb against LFA-1 (C), β1 integrins (D), α4 (E), and α5 integrin subunits (F) and the chemokine receptors CXCR3 (G), CCR5 (H), and CCR7 (I). J, Rat anti-human β7-integrin (filled histogram) with line overlay of goat anti-rat immunoglobulins: alexa-488.
