Inclusion body myositis (IBM) belongs to a group of muscle diseases known as the inflammatory myopathies. The presence of antibody-secreting plasma cells in IBM muscle implicates the humoral immune response in this disease. However, whether the humoral immune response actively contributes to IBM pathology has not been established. We sought to investigate whether the humoral immune response in ...

The ability to react to unfavorable environmental changes is crucial for survival and reproduction, and several adaptive responses to stress have been conserved during evolution [1-3]. Specific immune and heat shock responses mediate the elimination of invading pathogens and of damaged proteins or cells [4-6]. Furthermore, MAP kinases and other signaling factors mediate cellular responses to a ...

CD23, also known as the low affinity IgE receptor (FcepsilonRII), has been hypothesized to have a role in IgE regulation. A new CD23 transgenic mouse was generated using the MHC class I promoter and IgH enhancer to further test the hypothesis that CD23 plays a role in the down-regulation of IgE. Study of three founder lines by FACS showed overexpression to varying extents on both B and T lympho...

Human cases of infection due to a novel swine-origin variant of influenza A virus subtype H3N2 (H3N2v) have recently been identified in the United States. Pre-existing humoral and cellular immunity has been recognized as one of the key factors in limiting the infection burden of an emerging influenza virus strain, contributing to restrict its circulation and to mitigate clinical presentation. A...

The influence of Eleuterococcus senticosus on cellular and humoral immune response was evaluated. The experiments were performed on animal models (Balb/c mice and F1 crossbreeds Balb/cxC3H). It was shown that Eleuterococcus has immunomodulatory properties. This substance enhanced the cellular response of the mouse immunological system (chemokinetic activity of mice spleen cells, GvH reaction). ...

We have examined the human humoral immune response directed against proteins of Listeria monocytogenes in both healthy individuals and listeriosis patients. Two major targets for an antibody response were found in individuals that did not suffer from listeriosis: listeriolysin (Hly) and the recently described internalin-related protein (IrpA). In contrast, the humoral response in listeriosis pa...

Article Kinetics and biological characteristics of humoral response developing after SARS-CoV-2 infection: implications for vaccination was published on July 1, 2021 in the journal Clinical Chemistry Laboratory Medicine (CCLM) (volume 59, issue 8).

coincidence of autoimmune diseases such as immune thrombocytopenic purpura (itp) with  immunodeficiencies has  been  reported  previously in  patients  who  suffered  from primary antibody deficiency (pad). but there is no original study on immunological profiles of itp patients to find out their probable immune deficiency. in this case-control study, itp patients’ humoral immunity was investig...

Previous studies have compared the immune systems of wild and of laboratory rodents in an effort to determine how laboratory rodents differ from their naturally occurring relatives. This comparison serves as an indicator of what sorts of changes might exist between modern humans living in Western culture compared to our hunter-gatherer ancestors. However, immunological experiments on wild-caugh...
