Costimulatory molecules (CD80, CD86, CD40, GITR, and ICOS), adhesion molecules (VCAM-1 and P-selectin), and signaling molecules involved in cytokine regulation (Tbx21 and Socs1) were also increased with Hb infection and decreased with anti-IL-7Rα M595 treatment in a dose-dependent manner. This evidence concerns the gene CD80 and infection.
