Intratumoral immunoglobulin isotypes predict survival in lung adenocarcinoma subtypes [PDF]
Background The role of tumor-infiltrating B-cells (TIBs) and intratumorally-produced antibodies in cancer-immunity interactions essentially remains terra incognita.

Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar [PDF]
There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains μ, δ and τ, respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, Atlantic salmon (Salmo salar)

Detection of immunoglobulin isotypes from dried blood spots. [PDF]
The study was designed to determine the sensitivity and reproducibility of recovering immunoglobulin (Ig) isotypes (IgG subclasses, IgA, IgE and IgM classes) from dried blood spots (DBS), a methodologic subcomponent of the Upstate KIDS Study. A multiplexed Luminex assay was used for IgG1/2/3/4, IgA and IgM analysis; an ELISA was used for IgE.

Evolution of the Immunoglobulin Isotypes—Variations of Biophysical Properties among Animal Classes [PDF]
The adaptive immune system arose around 500 million years ago in jawed fish, and, since then, it has mediated the immune defense against pathogens in all vertebrates.

B cells defined by immunoglobulin isotypes. [PDF]
SummaryThe ability of B cells to generate antibodies and provide long-lived protective immunity is the cornerstone of vaccination and has contributed to the success of modern medicine. The nine different antibody subclasses produced by humans have effector functions that differ according to antigen type and route of exposure.

Aging and immunoglobulin isotype patterns in oral tolerance [PDF]
In the present review we address oral tolerance as an important biological phenomenon and discuss how it is affected by aging. Other factors such as frequency of feeding and previous digestion of the antigen also seem to influence the establishment of ...

Cytokine and Antibody Isotype Responses in Vaccinated Healthcare Workers with SARS-CoV-2 Breakthrough Infections [PDF]
Background: Healthcare workers (HCWs) are at high risk of breakthrough SARS-CoV-2 infections despite complete vaccination schedules. There are gaps in our understanding of the specific antibody isotypes and cytokine profiles produced during an infection ...

Marsupial Ig genomics revisited and the potential role of retroelements in the limited number of heavy chain isotypes [PDF]
Background Marsupials have limited germline antibody heavy chain variable (VH) gene diversity and more complex light chain variable gene diversity. They also appear to have a limited repertoire of immunoglobulin heavy chain (IgH) isotypes.
