Humoral immunity in humanized mice: a work in progress

Area of Science:

• Immunology
• Infectious Diseases
• Vaccinology

Background:

• Historically, humanized mice have shown limitations in modeling human humoral immunity.
• Newer humanized mouse models are overcoming these limitations.

Purpose of the Study:

• To review the advancements in humanized mouse models for studying human humoral immunity.
• To discuss the potential and limitations of these models.

Main Methods:

• Review of recent literature on humanized mice with targeted IL2Rγc gene disruption.
• Analysis of studies reporting antigen-specific, class-switched human antibody production.

Main Results:

• Severely immunodeficient mice with IL2Rγc gene disruption can support human antibody production.
• These antibodies exhibit antigen-specificity and neutralizing activities.
• Humanized mice are increasingly capable of modeling human humoral immune responses.

Conclusions:

• Humanized mice are becoming valuable tools for studying human humoral immunity.
• Further research and model development hold significant potential for immunology and vaccinology.
