Objective:

To assess the adaptive and humoral immune responses, including specific antibody production and B cell activation, of γδ HuTCR-T1 mice compared with wild-type mice following immunization with collagen and keratin antigens.

Approach:

Key Findings:

• γδ HuTCR-T1 mice showed significantly increased antigen-specific antibody-secreting cells.
• Elevated serum levels of antigen-specific IgG, IgA, and IgE were observed.
• Expansion of plasma and memory B cell populations was noted in spleen and blood.
• A distinct cytokine profile was identified, with increased production of IL-4, IL-6, IL-10, IL-17, TGFβ, IFNγ, and TNFα.
• Serum levels of anti-ANA antibodies remained below detection threshold.

Interpretation:

Human γδ T cells enhance adaptive and humoral immunity through direct interactions and cytokine-driven mechanisms that promote B cell maturation and activation, suggesting potential therapeutic avenues in immunotherapy.

Limitations:

• The study was conducted in a mouse model, which may not fully replicate human immune responses, limiting the direct applicability of findings.
• Further research is needed to explore the long-term effects of γδ T cell modulation on B cell responses and their implications for human health.

Conclusion:

The findings highlight the role of human γδ T cells in regulating immune responses and support the utility of the γδ HuTCR-T1 model for preclinical studies, paving the way for future research in immunotherapy.
