Mouse and human antibodies bind HLA-E-leader peptide complexes and enhance NK cell cytotoxicity.

Journal Article Commun Biol · March 28, 2022 The non-classical class Ib molecule human leukocyte antigen E (HLA-E) has limited polymorphism and can bind HLA class Ia leader peptides (VL9). HLA-E-VL9 complexes interact with the natural killer (NK) cell receptors NKG2A-C/CD94 and regulate NK cell-media ... Full text Link to item Cite

mRNA-encoded HIV-1 Env trimer ferritin nanoparticles induce monoclonal antibodies that neutralize heterologous HIV-1 isolates in mice.

Journal Article Cell Rep · March 15, 2022 The success of nucleoside-modified mRNAs in lipid nanoparticles (mRNA-LNP) as COVID-19 vaccines heralded a new era of vaccine development. For HIV-1, multivalent envelope (Env) trimer protein nanoparticles are superior immunogens compared with trimers alon ... Full text Link to item Cite

Strategies for eliciting multiple lineages of broadly neutralizing antibodies to HIV by vaccination.

Journal Article Curr Opin Virol · December 2021 A prophylactic vaccine would be a powerful tool in the fight against HIV. Passive immunization of animals with broadly neutralizing antibodies (bnAbs) affords protection against viral challenge, and recent data from the Antibody Mediated Prevention clinica ...

Lipid nanoparticle encapsulated nucleoside-modified mRNA vaccines elicit polyfunctional HIV-1 antibodies comparable to proteins in nonhuman primates.

Journal Article NPJ Vaccines · April 9, 2021 The development of an effective AIDS vaccine remains a challenge. Nucleoside-modified mRNAs formulated in lipid nanoparticles (mRNA-LNP) have proved to be a potent mode of immunization against infectious diseases in preclinical studies, and are being teste ...

HIV mRNA Vaccines-Progress and Future Paths.

Journal Article Vaccines (Basel) · February 7, 2021 The SARS-CoV-2 pandemic introduced the world to a new type of vaccine based on mRNA encapsulated in lipid nanoparticles (LNPs). Instead of delivering antigenic proteins directly, an mRNA-based vaccine relies on the host's cells to manufacture protein immun ... Full text Link to item Cite

Cold sensitivity of the SARS-CoV-2 spike ectodomain.

Journal Article Nat Struct Mol Biol · February 2021 The SARS-CoV-2 spike (S) protein, a primary target for COVID-19 vaccine development, presents its receptor binding domain in two conformations, the receptor-accessible 'up' or receptor-inaccessible 'down' states. Here we report that the commonly used stabi ... Full text Link to item Cite

A Single Immunization with Nucleoside-Modified mRNA Vaccines Elicits Strong Cellular and Humoral Immune Responses against SARS-CoV-2 in Mice.

Journal Article Immunity · October 13, 2020 SARS-CoV-2 infection has emerged as a serious global pandemic. Because of the high transmissibility of the virus and the high rate of morbidity and mortality associated with COVID-19, developing effective and safe vaccines is a top research priority. Here, ...

Disruption of the HIV-1 Envelope allosteric network blocks CD4-induced rearrangements.

Journal Article Nat Commun · January 24, 2020 The trimeric HIV-1 Envelope protein (Env) mediates viral-host cell fusion via a network of conformational transitions, with allosteric elements in each protomer orchestrating host receptor-induced exposure of the co-receptor binding site and fusion element ...
