Using an established and efficient treatment regimen (13), these data show that this anti-4 integrin therapeutic approach is not efficient at blocking ongoing disease, at least in our model of PCD. The CCR5 chemokine receptor has been implicated in immune cell recruitment in several inflammatory diseases of the CNS (14). Although it was not highly expressed on cerebellum-infiltrating T cells at day 16 (Supplemental Physique 2A), we investigated whether CCR5 signaling was required for disease development. Treatment of L7-HA-PCD mice with a CCR5 antagonist (5P12-RANTES) starting on day 10 after disease induction did not block development of PCD and Purkinje neuron destruction, as shown in Supplemental Physique 2, BCE.
