With the implementation of the new Kidney Allocation System (KAS), there is increased reliance on a virtual crossmatch/histocompatibility risk assessment (vXM) for evaluating potential presence, as well as strength, of HLA antibodies against a potential donor.
The accuracy of such an assessment depends on the precision in the identification of the recipient’s antibody profile and the potential donor’s HLA typing. While the development of the single antigen bead (SAB) multiplex assay has improved the sensitivity and specificity of HLA-antibody detection, several limitations of the assay (specific to certain sensitized patients) can complicate accurate interpretation of results.
In this report, we focus on the “shared-epitope” phenomenon, a condition in which antibody strength can be underrepresented, or its presence completely missed, due to binding of the antibody to competing targets on multiple antigens (beads), effectively “diluting” the resulting MFI-readout. Here, we provide a relevant background to understand this phenomenon and present a couple of case studies illustrating how it can be investigated, leading to a more accurate histocompatibility consultation.

Description: p38 is a protein encoded by the MAPK14 gene which is approximately 41,2 kDa. p38 is localised to the cytoplasm and nucleus. It is involved in activated TLR4 signalling, the IL-2 pathway, toll-like receptor signalling pathways, the VEGF signalling pathway and 4-1BB pathway. This protein falls under the MAP kinase family. It acts as an integration point for multiple biochemical signals, and is involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is activated by various environmental stresses and proinflammatory cytokines. p38 is expressed in the brain, heart, placenta, pancreas and skeletal muscle. Mutations in the MAPK14 gene may result in patellar tendinitis and lumbosacral lipoma. STJ94878 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This polyclonal antibody detects endogenous levels of p38 protein. |
