Graft-versus-Host / Engraftment Considerations

Immunological compatibility factors that influence successful transplantation and maintenance of human cells or tissues in humanized mouse models. These parameters determine whether engrafted human immune systems function properly.

Overview

Graft-versus-host (GvH) and engraftment considerations refer to the immunological compatibility factors that influence successful transplantation and maintenance of human cells or tissues in humanized mouse models.

Frequently Asked Questions

How can GvH reactions be minimized?

Using specialized immunodeficient mouse strains (NSG, NOG, BRG) that lack adaptive immune components, and adding human cytokine knock-ins or HLA replacements to support engraftment.

HLA Humanized Models

Genetically engineered mice in which murine major histocompatibility complex (MHC) genes are replaced with human leukocyte antigen (HLA) alleles. These models recapitulate key aspects of human antigen presentation and adaptive immunity.

Cytokine / Receptor Humanization

The genetic replacement of mouse cytokines, receptors, or ligand, receptor pairs with their human equivalents. These models recreate critical components of the human immune network for accurate evaluation of human biologics.

Humanized Mouse Models

A genetically engineered mouse in which one or more human genes, immune system components, or biological pathways have been introduced to replicate aspects of human physiology, bridging the gap between basic research and clinical translation.
