Dermatitis herpetiformis (DH) is a chronic inflammatory condition characterized by an autoimmune reaction between IgA and epidermal transglutaminase (eTG). DH develops in a very small portion of gluten-sensitive and/or celiac patients. The results of this study indicate that DH can also develop in a rhesus monkey host with symptoms of idiopatic dermatitis.

Ubiquitination is a key posttranslational modification carried out by a set of three enzymes. Mutations of genes involved in this modification are associated with many different human diseases. Here, we describe protocols to detect protein ubiquitination in cultured cells in vivo and test tubes in vitro.

Detecting Reactive Oxygen Species

2023
Reactive oxygen species are chemically active, oxygen-derived molecules capable of oxidizing other molecules. Because of their reactive nature, there are many deleterious effects associated with unchecked ROS production, including structural damage to DNA and other biological molecules. However, ROS can also be mediators of physiological signaling. There is accumulating evidence that ROS play significant roles in everything from activation of transcription factors to the mediation of...
FAQs
In a typical immunoassay, IgA-specific capture or detection antibodies bind the target in a patient sample. The resulting antigen-antibody complexes produce a color, fluorescence, or chemiluminescent signal. Because signal strength is proportional to IgA concentration, comparing the measured readout with an assay calibration allows researchers to estimate how much IgA is present.
Total IgA measures the overall amount of this antibody class, whereas pathogen-specific IgA identifies antibodies directed toward a particular infectious target. The distinction separates general IgA abundance from an immune response associated with exposure or vaccination. This comparison can therefore support more focused interpretation than a total-IgA result alone.
Reliable interpretation depends on preserving the quality of patient samples and including appropriate assay controls. Poor handling or inadequate controls can make the measured signal harder to interpret, even when the detection chemistry functions as intended. Careful sample management and control results provide greater confidence that observed differences reflect IgA measurements rather than assay-related problems.
Researchers can use IgA detection to characterize mucosal immune responses, investigate infection-related antibody responses, assess changes following vaccination, or examine suspected antibody deficiencies. Its value depends on selecting the measurement that matches the research question, such as total IgA for overall abundance or pathogen-specific IgA for a targeted response.
IgA is concentrated at mucosal surfaces but is also present in blood, saliva, and other secretions. Measuring it across these sample types can help researchers examine antibody responses in locations relevant to mucosal defense, while blood measurements provide a different sample context. The resulting data can support broader characterization of immune protection.
An IgA measurement can contribute to evaluating suspected antibody deficiency by showing whether the measured amount is consistent with the investigation’s focus on overall IgA abundance. Total IgA is particularly relevant for this purpose, while pathogen-specific testing addresses a different question about targeted immune responses. Interpretation should remain linked to assay controls and sample quality.
