Colpitts1 1 Department of Microbiology, Boston University School of Medicine, National Emerging Infections Diseases Laboratories, Boston, MA First discovered by Lederberg and Tatum in 1946, conjugation is a form of horizontal gene transfer between bacteria that relies on direct physical contact between two bacterial cells (1). Unlike other forms of gene transfer, such as transformation or transduction, conjugation is a naturally occurring process in which...

Colpitts1 1 Department of Microbiology, Boston University School of Medicine, National Emerging Infections Diseases Laboratories, Boston, MA Transduction is a form of genetic exchange between bacteria that utilizes bacteriophages, or phages, a class of virus that infects exclusively prokaryotic organisms. This form of DNA transfer, from one bacterium to another by way of a phage, was discovered in 1951 by Norton Zinder and Joshua Ledererg, who termed the...

A Peptide Array-Based Detection of Anti-donor HLA Alloantibodies in Organ Recipients

2025
This video demonstrates an assay to detect anti-donor HLA alloantibodies in organ recipients. A peptide array is synthesized to represent potential epitopes for antibody-mediated organ rejection. The array is incubated with the recipient's serum, containing alloantibodies that bind to their target epitopes. Antibody binding is detected using chemiluminescence to identify donor-specific HLA epitopes that incite alloantibody reactivity.

Here, we present a protocol to induce tolerance in transplantation, and assess in vitro and in vivo the suppressive capacity of distinct cell subsets from the recipient and the immune status of the recipient toward donor or exogenous antigens.
FAQs
Recipient Preparation supports engraftment through several coordinated effects. Conditioning can reduce immune activity, remove or suppress host cells that would compete with donor material, and alter the tissue environment so it becomes more receptive. Together, these changes can improve donor-cell survival and help the transplanted material establish itself and contribute to tissue function.
Reducing immune activity can limit rejection and make the recipient more receptive to donor material, but preparation treatments can also impose toxicity. The design therefore requires a balance between achieving sufficient conditioning and avoiding excessive harm. This balance depends on the graft type, the recipient’s condition, and the intended level of tissue reconstitution.
Both resident host cells and the surrounding tissue environment can affect what happens after transplantation. Competing host cells may limit donor-cell establishment, while an unreceptive tissue setting may reduce survival or function. Recipient preparation addresses these barriers by suppressing competition and creating conditions that support engraftment, donor-cell persistence, and tissue reconstitution.
The preparation strategy changes according to whether the graft consists of hematopoietic stem cells, tissue for regenerative medicine, or donor material used in an experimental transplant model. Each setting may require a different balance of immune control, host-cell suppression, and tissue receptivity. Recipient condition also influences the design, so no single preparation approach fits every application.
Preparation begins by selecting conditioning measures suited to the graft and recipient. These measures may reduce immune activity, suppress or remove competing host cells, and establish a more receptive tissue environment. Only after these preparatory conditions are created is the donor material introduced. The sequence is intended to improve establishment and subsequent function.
Recipient Preparation is relevant whenever transplanted cells, tissues, or organs must establish themselves in a host. Its applications include hematopoietic stem cell transplantation, regenerative medicine, and experimental transplant models. Researchers and clinicians use the approach to support donor-cell survival, limit rejection, and promote tissue reconstitution while considering the risks associated with conditioning.
