MYD88 and Thrombocytopenia: Control C57BL/6 mice (Figure 5, column 2) or Myd88 deficient mice (Figure 5, column 6) injected with anti-platelet antibody both displayed thrombocytopenia with no significant difference in platelet counts between the 2 groups, consistant with phagocytosis of antibody opsonized platelets occurring in the absence of Myd88.
