New Role of Antibody in Bacterial Isolation

Journal of AOAC INTERNATIONAL, 2012
Abstract To eliminate the interference caused by Pseudomonas aeruginosa in the isolation of Salmonella, a rabbit polyclonal antibody against P. aeruginosa was prepared by inoculating four New Zealand rabbits with the pathogen. The antiserum was purified using saturated ammonium sulfate and added into Rappaport-Vassiliadis medium with ...

The Immunogenicity of Glutaraldehyde Inactivated PTx Is Determined by the Quantity of Neutralizing Epitopes

Vaccines
Background/Objectives: Chemically or genetically detoxified pertussis toxin (PTx) is a crucial antigen component of the acellular pertussis vaccine. Chemical detoxification using glutaraldehyde generally causes significant structural changes to the toxin.

Artificial surface labelling of Escherichia coli with StrepTagII antigen to study how monoclonal antibodies drive complement-mediated killing

Scientific Reports, 2023
Antibodies play a key role in the immune defence against Gram-negative bacteria. After binding to bacterial surface antigens, IgG and IgM can activate the complement system and trigger formation of lytic membrane attack complex (MAC) pores.

Diverse Mechanisms of Protective Anti-Pneumococcal Antibodies

Frontiers in Cellular and Infection Microbiology, 2022
The gram-positive bacterium Streptococcus pneumoniae is a leading cause of pneumonia, otitis media, septicemia, and meningitis in children and adults. Current prevention and treatment efforts are primarily pneumococcal conjugate vaccines that target the ...

Human antibody targeting Vibrio cholerae O1 O-specific polysaccharide induces an amotile hypovirulent bacterial phenotype: mechanism of protection against cholera

mBio
Antibodies targeting the O-specific polysaccharide (OSP) of Vibrio cholerae O1 are crucial determinants of protection against cholera. These antibodies agglutinate bacteria and, even in sub-agglutinating conditions, inhibit V. cholerae motility.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Single Domain Antibody application in bacterial infection diagnosis and neutralization

Frontiers in Immunology, 2022
Increasing antibiotic resistance to bacterial infections causes a serious threat to human health. Efficient detection and treatment strategies are the keys to preventing and reducing bacterial infections. Due to the high affinity and antigen specificity,

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Structure‐forward targeting of claudins with synthetic binders

FEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Isotype conversion of Staphylococcal-specific IgG into IgM broadens the reactivity to other bacterial pathogens

Cell Reports Medicine
Summary: Therapeutic antibodies are actively explored as alternative to treat or prevent bacterial infections. However, the narrow antigen specificity of IgG in combination with broad diversity in bacterial surface structures currently hampers the ...
