IFNA1 and Thrombocytopenia: It is noteworthy that there are important differences between the LCMV mouse model for thrombocytopenia, in which IFN-α/β mediates the decrease in platelet numbers, platelet dysfunction, and bleeding, and the LCMV primate model, in which the IFN-α/β expression is not remarkable and yet there are bleeding signs [117]–[119].
