Task: Answer Verification
Input (English): Question: Does atherogenesis in mice require CD40 ligand from bone marrow-derived cells?
Answer: These experiments demonstrate that CD40L modulates atherogenesis, at least in mice, primarily by its expression on nonhematopoietic cell types rather than monocytes, T lymphocytes, or platelets, a surprising finding with important pathophysiologic and therapeutic implications.
Output (English): no
