Imaging the glycome [PDF]

Proceedings of the National Academy of Sciences, 2009
Molecular imaging enables visualization of specific molecules in vivo and without substantial perturbation to the target molecule's environment. Glycans are appealing targets for molecular imaging but are inaccessible with conventional approaches.

High-Throughput Glycomic Methods

Chemical Reviews, 2022
Glycomics aims to identify the structure and function of the glycome, the complete set of oligosaccharides (glycans), produced in a given cell or organism, as well as to identify genes and other factors that govern glycosylation. This challenging endeavor requires highly robust, sensitive, and potentially automatable analytical technologies for the ...

Streptolysin O Deficiency in Streptococcus pyogenes M1T1 covR/S Mutant Strain Attenuates Virulence in In Vitro and In Vivo Infection Models

mBio, 2023
Mutation within the Streptococcus pyogenes (Streptococcus group A; Strep A) covR/S regulatory system has been associated with a hypervirulent phenotype resulting from the upregulation of several virulence factors, including the pore-forming toxin ...

Cellular O-Glycome Reporter/Amplification to explore O-glycans of living cells [PDF]

, 2015
Protein O-glycosylation has key roles in many biological processes, but the repertoire of O-glycans synthesized by cells is difficult to determine. Here we describe an approach termed Cellular O-Glycome Reporter/Amplification (CORA), a sensitive method ...

High-throughput mapping of RNA solvent accessibility at the single-nucleotide resolution by RtcB ligation between a fixed 5′-OH-end linker and unique 3′-P-end fragments from hydroxyl radical cleavage

RNA Biology, 2022
Given the challenges for the experimental determination of RNA tertiary structures, probing solvent accessibility has become increasingly important to gain functional insights.

Mosquito antiviral defense mechanisms: a delicate balance between innate immunity and persistent viral infection

Parasites & Vectors, 2019
Mosquito-borne diseases are associated with major global health burdens. Aedes spp. and Culex spp. are primarily responsible for the transmission of the most medically important mosquito-borne viruses, including dengue virus, West Nile virus and Zika ...

Streptococcus pyogenes vaccine candidates do not induce autoimmune responses in a rheumatic heart disease model

npj Vaccines, 2023
We have developed a candidate vaccine to protect against multiple strains of Streptococcus pyogenes infections. The candidate vaccine contains two synthetic peptides derived from S. pyogenes proteins: the M-protein epitope, p*17 and the IL-8 degrading S.

The glycointeractome of serogroup B Neisseria meningitidis strain MC58

Scientific Reports, 2017
Neisseria meningitidis express numerous virulence factors that enable it to interact with diverse microenvironments within the host, during both asymptomatic nasopharyngeal colonization and invasive disease.

N-glycolylneuraminic acid as a carbohydrate cancer biomarker

Translational Oncology, 2023
One of the forms of aberrant glycosylation in human tumors is the expression of N-glycolylneuraminic acid (Neu5Gc). The only known enzyme to biosynthesize Neu5Gc in mammals, cytidine-5′-monophosphate-N-acetylneuraminic acid (CMAH), appears to be ...

Shotgun ion mobility mass spectrometry sequencing of heparan sulfate saccharides [PDF]

, 2020
Despite evident regulatory roles of heparan sulfate (HS) saccharides in numerous biological processes, definitive information on the bioactive sequences of these polymers is lacking, with only a handful of natural structures sequenced to date.
