Preclinical safety and immunogenicity of Streptococcus pyogenes (Strep A) peptide vaccines

open access: yesScientific Reports, 2021
We have developed two candidate vaccines to protect against multiple strains of Strep A infections. The candidates are combinatorial synthetic peptide vaccines composed of a M protein epitope (J8 or p*17) and a non-M protein epitope (K4S2).

Discovery of Cofactor Competitive Inhibitors against the Human Methyltransferase Fibrillarin

open access: yesPharmaceuticals, 2021
Fibrillarin (FBL) is an essential and evolutionarily highly conserved S-adenosyl methionine (SAM) dependent methyltransferase. It is the catalytic component of a multiprotein complex that facilitates 2′-O-methylation of ribosomal RNAs (rRNAs), a ...

A CAF01-adjuvanted whole asexual blood-stage liposomal malaria vaccine induces a CD4+ T-cell-dependent strain-transcending protective immunity in rodent models

open access: yesmBio, 2023
Malaria is a leading cause of illness and death in children under 5 years of age in Sub-Saharan Africa. Currently, there is no highly efficacious malaria vaccine capable of inducing long-lasting immunity.

New Perspectives on Escherichia coli Signal Peptidase I Substrate Specificity: Investigating Why the TasA Cleavage Site Is Incompatible with LepB Cleavage

open access: yesMicrobiology Spectrum, 2023
Escherichia coli signal peptidase I (LepB) has been shown to inefficiently cleave secreted proteins with aromatic amino acids at the second position after the signal peptidase cleavage site (P2′).

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

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

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

open access: yesmBio, 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 ...

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

open access: yesnpj 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.

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

open access: yesParasites & 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 ...
