Anti-transglutaminase antibodies result in a form of gluten sensitivity in which a cellular response to Triticeae glutens that are crosslinked to tTG are able to stimulate transglutaminase specific B-cell responses that eventually result in the production of anti-transglutaminase antibodies IgA and IgG.
The endomysium contains a form of transglutaminase called "tissue transglutaminase" or "tTG" for short, and antibodies that bind to this form of transglutaminase are called endomysial autoantibodies (EmA). [6] The antiendomysial antibody test is a histological assay for patient serum binding to esophageal tissue from primate.
The IgG antibody is similar to AGA IgA, but is found at higher levels in patients with the IgA-less phenotype. It is also associated with coeliac disease and non-celiac gluten sensitivity. [5] [6] [7] Anti-gliadin antibodies are frequently found with anti-transglutaminase antibodies.
Inflammatory breast cancer is a high-grade aneuploid cancer, with mutations and overexpression of p53, [13] high levels of E-cadherin and abnormal cadherin function. It is often regarded as a systemic cancer. A large number of IBC cases present as triple negative breast cancer (TNBC).
Antibody recognition of gluten is complex. Direct binding to gluten such as anti-gliadin antibodies has an ambiguous pathogenesis in coeliac disease. The crosslinking of gliadin with tissue transglutaminase leads to the production of anti-transglutaminase antibodies, but this is mediated through T-cell recognition of gliadin.
Immunohistochemistry can be performed on tissue that has been fixed and embedded in paraffin, but also cryopreservated (frozen) tissue.Based on the way the tissue is preserved, there are different steps to prepare the tissue for immunohistochemistry, but the general method includes proper fixation, antigen retrieval incubation with primary antibody, then incubation with secondary antibody.

Invasive carcinoma NST accounts for half of all breast cancer diagnoses in women and is the most common type of invasive breast cancer. It is also the most commonly diagnosed form of male breast cancer. Invasive carcinoma NST is classified by its microscopic, molecular, and genetic features.
