Secretory immunoglobulins have a critical role in defense of the gastrointestinal tract and are known to act by preventing bacterial acquisition. A stringent murine model of bacterial infection with Salmonella enterica Typhimurium was used to examine ...

Natural polyreactive secretory immunoglobulin A autoantibodies as a possible barrier to infection in humans [PDF]
Secretory immunoglobulin A (S-IgA) was investigated in human secretions for the presence of natural antibodies (Abs) acting as the first "immune barrier" to infection before induction or boosting of specific responses. These molecules could be the secretory counterpart of the natural Abs in serum that were previously shown by our laboratory to be ...

Development of simple detection method of polyreactive secretory immunoglobulin A in saliva
The level of secretory immunoglobulin A (SIgA) in saliva is associated with the risk of upper respiratory infection and has been identified as a condition indicator for athletes and an indicator of mucosal immune function in the elderly. In addition, it has been suggested that non-specific polyreactive SIgA is present in human saliva and colostrum. The

Polyreactive antibodies in CLL correlate with the level of immunoglobulins not the number of B lymphocytes [PDF]
Polyreactive antibodies are a major part of natural antibody repertoire and can react with different types of antigens both from the host (e.g.

Polyreactive Binding of Antibodies Generated by Polyclonal B Cell Activation. I. Polyreactivity Could be Caused by Differential Glycosylation of Immunoglobulins [PDF]
The aim of this study was to gain knowledge of the pre‐immune repertoire with reactivity directed to the carbohydrate antigen dextran B512 (Dx). Polyclonal activation of spleen cells in mice has been estimated to be a method of revealing the available repertoire.

Natural antibodies – facts known and unknown
In contrast to adaptive antibodies, natural antibodies are present in a non-immunised organism from birth, and they do not include anti-Gal antibodies and/or anti-Gal natural antibodies, which are developed as a result of the effect of the -Gal epitope ...

Natural polyreactive immunoglobulin A antibodies produced in mouse Peyer’s patches
To understand the biological function of natural immunoglobulin A (IgA) antibodies in Peyer's patches (PP), we generated IgA monoclonal antibody (mAb) clones from the PP of normal, unimmunized, specific pathogen-free BALB/c mice and examined their reactivities by enzyme-linked immunosorbent assay (ELISA). Many of these antibodies reacted with more than

Maternal and infant gut microbiome
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

The G protein–coupled receptor (GPCR) superfamily consists of the most common targets of approved drugs. Targeting GPCRs offers appealing avenues for therapeutic development. Antibodies and their fragments, such as single‐domain antibodies (VHHs or nanobodies), have emerged as useful alternatives to small molecule pharmacophores as building blocks in ...
