Suppression of antigen-specific T cell proliferation by measles virus infection: role of a soluble factor in suppression.

abstract：:Human papillomavirus (HPV) E6 oncoproteins target numerous cellular proteins for ubiquitin-mediated degradation. In the case of p53 this is mediated by the E6AP ubiquitin ligase. However, there are conflicting reports concerning how central E6AP is to the global function of the HPV-16 and HPV-18 E6 oncoproteins. To in...
