Chloroquine 39-50 interferon alpha 1 Homo sapiens 12-21 19949061-5 2010 Our results indicate that chloroquine blocks TLR-mediated activation of pDC and MyD88 signaling, as shown by decreases in the levels of the downstream signaling molecules IRAK-4 and IRF-7 and by inhibition of IFN-alpha synthesis. Chloroquine 26-37 interferon alpha 1 Homo sapiens 209-218 19949061-8 2010 Our results indicate that TLR stimulation and production of IFN-alpha by pDC contribute to immune activation and that blocking of these pathways using chloroquine may interfere with events contributing to HIV pathogenesis. Chloroquine 151-162 interferon alpha 1 Homo sapiens 60-69
