ABSTRACT Expression of HLA-B57 is associated with restricted replication of human immunodeficiency virus (HIV), but the mechanism for its protective effect remains unknown. If ... advantage depends upon CD8 T-cell recognition of B57-restricted epitopes, mother-to-child transmission of escape ... could nullify its protective effect. However, if the B57 advantage is largely mediated by selection for fitness-attenuating viral mutations within B57-restricted epitopes, such as T242N in TW10-Gag, ... the haploidentical infant.
