Humanized Immune Checkpoint Mouse Models

Immune checkpoint inhibitors have appeared to be effective in the treatment of cancer. Genetic engineering techniques enable researchers to develop humanized mouse models that can interact with humanized antibodies to CTLA4 or PD1. Greentech Bioscience currently provides you with validated humanized mouse models for immune checkpoint models, including humanized PD-1 mouse model and humanized CTLA-4 mouse model for preclinical testing of novel immune checkpoint targeted therapies.

Humanized Immune Checkpoint Mouse Models

1. Humanized PD-1 mouse model (hPD-1 mice)

Programmed cell death-1 (PD-1) plays an imperative part in inhibiting immune responses and advancing self-tolerance. The hPD-1 mouse model provides a tool for pre-clinical screening and efficacy evaluation of immune-oncology therapies targeting PD-1 in fully immunocompetent mice.

2. Humanized CTLA-4 mouse model (hCTLA-4 mice)

Cytotoxic T-lymphocyte-associated protein 4 (CTLA4, also known as CD152) acts as an immune checkpoint. Humanized CTLA-4 mice are developed through transgenic technologies, enabling preclinical testing of cancer immunotherapy and other applications.
