Immunotherapeutics, as a treatment of human disease, has brought benefits to both patients and commercial success to many drug developers. However, determining the best experimental immunotherapy model is still a major obstacle toward answering questions like how to optimize the immuno-oncology agent to finally developing better treatments.

Based on the complexity of human disease, the selection of the experimental mice is the key to the study. Combining the in-depth knowledge of each model immunological features and detailed model construction strategy according to specific requirements results in highly human-relevant models for progressing the research.

Intending to help researchers quickly obtain valuable research animal models for human disease studies, Cyagen has established its drug development and screening platform through the combination of introduction and self-development in high-quality control - to serve research in cancer, immunity, endocrinology, cardiovascular disease (CVD), neurology, and infectious diseases. We offer various ready-to-use research mouse models and keep developing models and services for drug development and efficacy evaluation is now a high priority in our current R&D activities.

Congenital immunodeficient mice are the most widely used in scientific research studies, they are usually applied as laboratory animals for tumor models. Common examples of congenitally immunodeficient backgrounds include Nude mice, severe combined immunodeficient (SCID) mice, NOD Scid mice, among others. Among these, severe combined immunodeficient (SCID) mice are widely used in the construction of humanized mice due to their deficiency of T, B and NK immune cells.

Here Cyagen providing immunodeficient mouse models for your developing and testing immunotherapeutic strategies:

Category Strain Name Background Order
Immunodeficient Mice NOD-Scid NOD
C-NKG NOD/Shi-Scid
Mice with Human Immune System BRGSF-HIS /

Compared with nude mice, SCID mice and NOD Scid, the Scid mouse - BRGSF is more easily to implanting into human tissues.
Here below are the comparisons of commonly-used Immunodeficient mice:

Mouse Strain Deficiency Advantages Disadvantages Applications
C-NKG No functional T, B and NK cells
Decreased complement activity
Impaired functions of macrophages and dendritic cells
No T and B cell leakage with age
Not well characterized.
Efficacy and safety assessment of cellular immunotherapy
Generation of humanized mouse models (e.g. using human PBMC or HSC to rebuild human immune system in mice)
Hematopoiesis and stem cells
BRGSF No functional T, B and NK cells
The most immunodeficient mouse models on the current market
Highly compatible with various sources of cell line-derived xenografts (CDXs) and patient-derived xenografts (PDXs)
Suitable for evaluating the therapeutical effect of radiotherapy
Powerful tool for complement-dependent cytotoxicity (CDC) studies
Not well characterized.
CDX and PDX (e.g., solid tumor and hematoma research)
Efficacy and safety assessment of cellular immunotherapy (e.g., CAR-T)
Vaccine development (e.g., HIV)
Myeloid compartment development (e.g., monocytes/macrophages)
Construction of mouse models with reconstituted human immune systems (e.g. BRGSF-HIS)
NOD-SCID No functional T and B cells, NK cells impaired Well-characterized. Low NK cell activity.
Very low leakiness with age.
High incidence of lymphomas.
Higher levels of engraftment of PBMC and
hematopoietic stem cells compared with the SCID strain.
SCID (scid) No functional T and B cells Better engraftment of allogeneic and xenogeneic tumor cells and tissues than in Nude strain. Functional NK cells. Spontaneous lymphomas. Transplantation of murine and human (xenogeneic) tumors for imaging, metastasis and new therapies studies. Low levels of engraftment of human PBMC and fetal hematopoietic tissues.

Since the current common animal models cannot truly simulate the tumor microenvironment (TME) of the patient with cancer, which greatly limits their applications in the area of translational Immunotherapy. Therefore, there is an urgent need to establish animal models with reconstituted human immune systems for relevant translational research. Mouse models with reconstituted human immune systems refer to immunodeficient mouse models engrafted with human hematopoietic stem cells (HSCs), lymphocytes or tissues to reconstitute a functional human immune system. These models can be used for tumor growth study in the environment of the human immune system, and anti-tumor therapy assessment, especially the efficacy of immunotherapy and related mechanisms.

Immune checkpoints (ICPs) are regulators of immune activation. They help the immune system to maintain an optimal balance between autoimmune disease prevention and tumor elimination. Immune checkpoint inhibitors are antibody drugs developed for the corresponding immune checkpoints, which mainly reactivate the anti-tumor immune response by blocking co-suppressive T cell signaling. Although the amino acid sequence homology between the immune checkpoint genes of ordinary mice and the corresponding human genes is generally about 60%, antibodies that recognize human immune checkpoint proteins cannot identify the corresponding proteins in mice under normal circumstances - which may be solved with the humanization of mouse immune checkpoint genes.

Here Cyagen is providing humanized immune checkpoint mouse models for your developing and testing immunotherapeutic strategies:

Key Features of Humanized Immune Checkpoint (ICP) Mice
  • Evaluating the effectiveness of drugs targeting human immune checkpoints efficiently
  • No need to develop a surrogate antibody
  • It can be used for the construction of a syngeneic mouse model
  • Compared with PBMC/HSC humanized mouse model, it greatly reduces costs, saves research resources, and efficiently obtains reliable experimental data.
Applications of Humanized Immune Checkpoint (ICP) Mice

The humanized immune checkpoint mouse enables the in vivo efficacy and safety assessment of fully immunocompetent mice:

  • ● Use with the mouse (humanized) tumor cell lines
    e.g. Humanized tumor cell line MC38-hPD-L1 - Use hPD-1 mouse model together with cell line MC38-hPD-L1 as a syngeneic tumor model for testing the efficacy of combination therapies targeting human PD-1 and human PD-L1.
  • ● Cross with humanized immune checkpoint mice
    e.g. hPD-1/hVISTA model - enables assessment of both compounds targeting human PD-1 and/or human VISTA in immunocompetent mice.
