Although BCL-6 (-)/syn-1(+) RS cells of HIV-HD express CD40 , they are not surrounded by CD40 ligand -positive ( CD40L +) reactive T lymphocytes , which, in HD of the general population, are thought to regulate the disease phenotype through CD40 /CD40L interactions.
 protein: CD40; protein: CD40; cell type: CD40 ligand -positive ( CD40L +) reactive T lymphocytes; protein: CD40L; protein: CD40; protein: /CD40L; cell line: RS cells; protein: CD40 ligand; protein: BCL-6
