TIV Vaccination Modulates Host Responses to Influenza Virus Infection that Correlate with Protection against Bacterial Superinfection [PDF]

Vaccines, 2019
Background: Influenza virus infection predisposes to secondary bacterial pneumonia. Currently licensed influenza vaccines aim at the induction of neutralizing antibodies and are less effective if the induction of neutralizing antibodies is low and/or the

Novel antibody assessment method for microbial compositional alteration in the oral cavity

Biochemistry and Biophysics Reports, 2022
Recently, it has been demonstrated that dysbiosis, an alteration in commensal microflora composition, is intimately involved in the onset of a variety of diseases.

Increased levels of IgG antibodies against human HSP60 in patients with spondyloarthritis. [PDF]

PLoS ONE, 2013
Spondyloarthritis (SpA) comprises a heterogeneous group of inflammatory diseases, with strong association to human leukocyte antigen (HLA)-B27. A triggering bacterial infection has been considered as the cause of SpA, and bacterial heat shock protein ...

Removal of natural anti-αGal antibodies elicits protective immunity against Gram-negative bacterial infections

Frontiers in Immunology, 2023
Antibody-dependent enhancement (ADE) of bacterial infections occurs when blocking or inhibitory antibodies facilitate the infectivity of pathogens. In humans, antibodies involved in ADE of bacterial infections may include those naturally produced against

Functional Activity of Antibodies Directed towards Flagellin Proteins of Non-Typhoidal Salmonella. [PDF]

PLoS ONE, 2016
Non-typhoidal Salmonella (NTS) serovars Typhimurium and Enteritidis are major causes of invasive bacterial infections in children under 5 years old in sub-Saharan Africa, with case fatality rates of ~20%.

Compensatory intestinal immunoglobulin response after vancomycin treatment in humans

Gut Microbes, 2021
Intestinal immunoglobulins (Ig) are abundantly secreted antibodies that bind bacteria and bacterial components in the gut. This binding is considered to accelerate bacterial transit time and prevent the interaction of potentially immunogenic compounds ...

Vaccine-induced, but not natural immunity, against the Streptococcal inhibitor of complement protects against invasive disease

npj Vaccines, 2021
Highly pathogenic emm1 Streptococcus pyogenes strains secrete the multidomain Streptococcal inhibitor of complement (SIC) that binds and inactivates components of the innate immune response. We aimed to determine if naturally occurring or vaccine-induced

Antibodies against bacterial membrane proteins [PDF]

Journal of Endotoxin Research, 1999
Prior studies have shown that antiserum raised to the Escherichia coli J5 vaccine binds to three bacterial outer membrane proteins (OMPs) that are present on serum-exposed smooth Enterobacteriaceae and in LPS-containing fragments that are released by bacteria incubated in human serum.

A Novel Autoantibody Induced by Bacterial Biofilm Conserved Components Aggravates Lupus Nephritis

Frontiers in Immunology, 2021
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with multiple autoantibody production and often affects the kidneys, known as lupus nephritis. However, the mechanism underlying lupus nephritis development is unclear.
