Approaches to study interactions between human immune components and human tumours

---|---|---|---|---|
Tumour | Immune system | Advantages | Disadvantages | |
Allograft | HLA mismatched with immune system: PDX and CDX | PBMCs, HSPCs, and human fetal liver CD34+ HSPCs and autologous fetal thymus tissue | Enable studies of immune regulatory properties of the tumour microenvironment Abundance of immune cells and HSPCs Enable modelling graft versus tumour response |
Immune system allogeneic to tumour No HLA-restricted tumour antigen-specific T cell responses |
Autograft | Autologous to immune system: PDX | PBMCs, HSPCs expanded from PBMCs following mobilization with G(M)-CSF or bone marrow samples, and tumour-infiltrating lymphocytes | Immune system autologous to tumour Potential for HLA-restricted tumour antigen-specific T cells |
Require generation of PDX Limited availability of immune cells and HSPCs from patients With HSPC engraftment, development of HLA-restricted T cells will be limited |
CDX, cell line-derived xenograft; G(M)-CSF, G-CSF and/or GM-CSF; HSPCs, haematopoietic stem and progenitor cells; PBMCs, peripheral blood mononuclear cells; PDX, patient-derived xenograft.
