[HTML][HTML] Protection against SARS-CoV-2 infection by a mucosal vaccine in rhesus macaques

Y Sui, J Li, R Zhang, SK Prabhu, H Andersen… - JCI insight, 2021 - ncbi.nlm.nih.gov
Effective SARS-CoV-2 vaccines are urgently needed. Although most vaccine strategies
have focused on systemic immunization, here we compared the protective efficacy of 2 …

Chemically controlled epigenome editing through an inducible dCas9 system

T Chen, D Gao, R Zhang, G Zeng, H Yan… - Journal of the …, 2017 - ACS Publications
Although histone modifications are associated with gene activities, studies of their causal
relationships have been difficult. For this purpose, we developed an inducible system …

Glycan remodeling of human erythropoietin (EPO) through combined mammalian cell engineering and chemoenzymatic transglycosylation

Q Yang, Y An, S Zhu, R Zhang, CM Loke… - ACS chemical …, 2017 - ACS Publications
The tremendous structural heterogeneity of N-glycosylation of glycoproteins poses a great
challenge for deciphering the biological functions of specific glycoforms and for developing …

One-Pot Conversion of Free Sialoglycans to Functionalized Glycan Oxazolines and Efficient Synthesis of Homogeneous Antibody–Drug Conjugates through Site …

C Ou, C Li, R Zhang, Q Yang, G Zong, Y Dai… - Bioconjugate …, 2021 - ACS Publications
Antibody–drug conjugates (ADCs) are an important class of therapeutic agents that harness
the highly specific antigen targeting property of antibodies to deliver toxic drugs for targeted …

[PDF][PDF] Synthetic three-component HIV-1 V3 glycopeptide immunogens induce glycan-dependent antibody responses

H Cai, J Orwenyo, JP Giddens, Q Yang, R Zhang… - Cell chemical …, 2017 - cell.com
Eliciting broadly neutralizing antibody (bNAb) responses against HIV-1 is a major goal for a
prophylactic HIV-1 vaccine. One approach is to design immunogens based on known …

[HTML][HTML] Revisiting the substrate specificity of mammalian α1, 6-fucosyltransferase reveals that it catalyzes core fucosylation of N-glycans lacking α1, 3-arm GlcNAc

Q Yang, R Zhang, H Cai, LX Wang - Journal of Biological Chemistry, 2017 - ASBMB
The mammalian α1,6-fucosyltransferase (FUT8) catalyzes the core fucosylation of N-glycans
in the biosynthesis of glycoproteins. Previously, intensive in vitro studies with crude extract …

Multivalent antigen presentation enhances the immunogenicity of a synthetic three-component HIV-1 V3 glycopeptide vaccine

H Cai, R Zhang, J Orwenyo, J Giddens… - ACS Central …, 2018 - ACS Publications
HIV-1 envelope glycoproteins gp120 and gp41 are presented on the virus surface as a trimer
of heterodimer and are the targets of broadly neutralizing antibodies (bNAbs). We describe …

The interplay of protein engineering and glycoengineering to fine‐tune antibody glycosylation and its impact on effector functions

Q Wang, T Wang, R Zhang, S Yang… - Biotechnology and …, 2022 - Wiley Online Library
The N‐glycan pattern of an IgG antibody, attached at a conserved site within the fragment
crystallizable (Fc) region, is a critical antibody quality attribute whose structural variability can …

Comparative studies on the substrate specificity and defucosylation activity of three α-l-fucosidases using synthetic fucosylated glycopeptides and glycoproteins as …

SK Prabhu, C Li, G Zong, R Zhang, LX Wang - Bioorganic & medicinal …, 2021 - Elsevier
Core fucosylation is the attachment of an α-1,6-fucose moiety to the innermost N-acetyl
glucosamine (GlcNAc) in N-glycans in mammalian systems. It plays a pivotal role in modulating …

An intranasally administrated SARS-CoV-2 beta variant subunit booster vaccine prevents beta variant replication in rhesus macaques

Y Sui, J Li, H Andersen, R Zhang, SK Prabhu… - PNAS …, 2022 - academic.oup.com
Emergence of SARS-CoV-2 variants and waning of vaccine/infection-induced immunity
pose threats to curbing the COVID-19 pandemic. Effective, safe, and convenient booster …
