Corrections and Clarifications
In figures 1B and 2C of the report "Dendritic cells exposed to human immunodeficiency virus type-1 transmit a vigorous cytopathic infection to CD4+ T cells" by P. U. Cameron et al. (17 July, p. 383), the y axes should have read, "RTase 103 CPM/µl." The last line of reference 20 should have read "agarose gel stained with ethidium bromide."
