WebVaccine immunogens designed as chimeras of the spike protein receptor-binding domain of two distinct SARS-CoV-2 variants elicit broad serum neutralization and protection from infection by the Beta, Delta, and Omicron variants in mice and macaques. The chimeric approach is applicable for rapid updating of immunogens against both circulating and …
WebThe spike protein is composed of three identical chains, that together form a complex with a small domain inside the virus, a membrane-spanning segment, and a large ectodomain that extends outward from the virus. In addition, the spike is a glycoprotein: the ectodomain is covered with sugar chains that help to mask the virus from the immune system. define object javascriptWebApr 13, 2024 · Virus entry into animal cells is initiated by attachment to target macromolecules located on host cells. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) trimeric spike glycoprotein targets host angiotensin converting enzyme 2 to gain cellular access. The SARS-CoV-2 glycoprotein contains a neurotoxin-like region that … define ojaiWebDec 7, 2024 · We therefore established a computational design protocol that stabilizes the prefusion state while destabilizing the postfusion conformation. As a proof of concept, we applied this principle to the fusion protein of the RSV, hMPV, and SARS-CoV-2 viruses. For each protein, we tested less than a handful of designs to identify stable versions. define ojearWebNov 4, 2024 · The spike protein is the part of the virus that attaches to a human cell to infect it, allowing it to replicate inside of the cell and spread to other cells.
