2 However, some emerging candidates are based on other viral proteins such as membrane and nucleoprotein.2 Although no immunological correlate of protection against SARS-CoV-2 has yet been identified, the major focus has been on the induction of neutralizing antibodies to spike protein that likely ...
The spike (S) proteins have two subunits, namely S1 and S2 subunits. Binding of S1 leads to a conformational change in S2, hence the primary function of S1 is to bind, while that of S2 is to fuse. For viral entry, the N-terminal of S (S1) binds ACE2 receptor. Binding of S1 to...

aThe SARS-CoV-2 virus lipid bilayer comprising the spike protein (S, violet), the membrane protein (M, blue) and the envelope protein (E, orange), and the viral RNA (white) associated with the nucleocapsid protein (N, pink) are shown.bDifferent steps of SARS-CoV-2 replication cycle are...
Genes encoding type VI secretion systems (T6SS) are widely distributed in pathogenic Gram-negative bacterial species. In Vibrio cholerae, T6SS have been found to secrete three related proteins extracellularly, VgrG-1, VgrG-2, and VgrG-3. VgrG-1 can covalently cross-link actin in vitro, ...
which are composed of fragments of mRNA that are taken up by immune cells, which transcribe the mRNA into spike proteins, the same ones that are found on the surface of SARS-CoV-2, which leads to immune recognition of these proteins and creation of antibodies against these proteins. These ...
There are a lot of important proteins circulating in the bloodstream and it is crucial that they are not lost in urine. The nephron possesses a filtration system that keeps protein in while removing harmful wastes. If this filtration system is damaged (glomerular disease) then a much more sever...
infection, HLA-C and HLA-E85 are exempted from downregulation, resulting in impaired recognition of the infected cells [209]. Furthermore, although NKG2D ligands are upregulated in HIV-infected cells, viral accessory proteins hamper the activation of NK cells [17,210]. HIV nef protein ...
How do carbohydrates fats and proteins get digested? Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units:Carbohydrates into sugars.Proteins into amino acids.Fats into fatty acids and glycerol. ...
The vaccine is based on a common poultry virus called the Newcastle Disease Virus (NDV), which can replicate in humans but is harmless. The scientists engineered NDV to produce the spike proteins of the SARS-CoV-2 virus which causes COVID-19, tricking the body into mounting an immune respon...
