A High Throughput MHC II Binding Assay for Quantitative Analysis of Peptide Epitopes
0 Views •
Cited by 21 •
2014
Biochemical assays with recombinant human MHC II molecules can provide rapid, quantitative insights into immunogenic epitope identification, deletion, or design. Here, a peptide-MHC II binding assay scaled to 384-well plates is described. This cost effective format should prove useful in the fields of protein deimmunization and vaccine design and development.

2026
Start with an immune cell culture infected with pathogenic bacteria that form intracellular inclusion bodies.The bacterial infection impairs the antigen presentation pathway in the immune cells.Take an uninfected culture as a control.Next, add a model protein antigen and incubate.Immune cells internalize, process, and present the model antigen-derived peptides on MHC-I molecules.After incubation, wash the cells to remove any unprocessed antigen.Fix the cells, then add a quenching agent to...

A Modified Heterotopic Swine Hind Limb Transplant Model for Translational Vascularized Composite Allotransplantation (VCA) Research
0 Views •
Cited by 34 •
2013
Vascularized Composite Allotransplantations (VCA) have become a clinical reality. However, broad clinical application of VCA is limited by chronic multi-drug immunosuppression. The authors present a reliable and reproducible large animal model to translate novel immunomodulatory strategies that can minimize or potentially eliminate the need of immunosuppression in VCA.

This procedure demonstrates the purification and in vitro expansion of antigen specific CD4+ T cells from whole peripheral blood and their visualization using MHC class II tetramers. Tetramers permit the direct visualization of T cells with a single antigen specificity and defined MHC class II restriction.
FAQs
SLA is the swine designation for major histocompatibility complex molecules. Class I and class II molecules bind peptide fragments and display them to T cells. The resulting antigen-presentation profile determines which immune signals can be examined in a given animal. Researchers can therefore relate differences in T-cell responses to documented SLA features across controlled experiments.
A characterized genetic background helps separate an effect linked to SLA variation from changes arising elsewhere in the genome or between animals. This control is important because immune responses can otherwise be difficult to attribute to antigen-presentation differences. Using documented backgrounds strengthens comparisons among experimental groups and improves confidence that observed patterns reflect the biological question being tested.
Researchers can interpret an immune response by relating it to the animal’s documented SLA haplotype and antigen-presentation profile, then considering remaining variation separately. This approach does not eliminate biological differences; it makes their sources more distinguishable. Consequently, a response associated with a particular MHC context can be evaluated without automatically attributing every group difference to MHC.
Characterized SLA profiles give transplantation studies a defined immunological context for examining compatibility. In xenotransplantation, the same information helps researchers study responses involving a pig donor or recipient while accounting for known MHC-related factors. This supports clearer interpretation of whether an experimental outcome is associated with antigen-presentation differences rather than an undocumented genetic background.
In vaccine evaluation, the documented antigen-presentation profile helps researchers interpret how immune responses develop in a controlled swine model. In infectious-disease studies, the same control can aid comparisons of disease-related immune responses across animals with known SLA backgrounds. These applications make it easier to connect experimental findings with the specific MHC context in which they were observed.
These animals also support investigations of immune-mediated disorders, where separating MHC-dependent effects from other variation can clarify disease-related immune findings. Their reproducible, documented antigen-presentation profiles strengthen interpretation within the study and can improve translation to human medicine. The value is therefore not limited to measuring disease; it includes understanding how defined immune genetics shapes the result.
