The guidelines for the implementation and reporting of HLA nomenclature for the World Marrow Donor Association have served as a reliable standard for communication of HLA data in the hematopoietic cell transplantation process. Wider use of next‐generation sequencing made a special provision of the guidelines increasingly pertinent: how to communicate novel HLA alleles. Novel alleles need to be recognized...
The HIV-1 envelope glycoprotein complex (Env) is the focus of vaccine development aimed at eliciting humoral immunity. Env's extensive and heterogeneous N-linked glycosylation affects folding, binding to lectin receptors, antigenicity and immunogenicity. We characterized recombinant Env proteins and virus particles produced in mammalian cells that lack N-acetylglucosaminyltransferase I (GnTI), an...
Many viruses transmitted via the genital or oral mucosa have the potential to interact with dendritic cell-specific intercellular adhesion molecule-3 grabbing non integrin (DC-SIGN) expressed on immature dendritic cells (iDCs) that lie below the mucosal surface. These cells have been postulated to capture and disseminate human immunodeficiency virus type-1 (HIV-1) to CD4 + lymphocytes, potentially...
Herpesviruses employ many mechanisms to evade the immune response, allowing them to persist life-long in their hosts. The Epstein-Barr virus (EBV) nuclear antigen 1 (EBNA-1) and, more recently, the latency-associated nuclear antigen 1 (LANA-1) of the Kaposi Sarcoma Herpesvirus have been shown to function as in cis-acting inhibitors of antigen presentation. In both proteins, long simple repeat elements...
HIV-1 evades antibody-mediated neutralization in many cunning ways. The recent structural characterization of a conserved neutralization epitope on the envelope glycoprotein complex (Env) provides clues to the vulnerabilities of the virus. We discuss these observations and explain their relevance for HIV-1 vaccine design.
