Background:

Current immunotoxicity testing methods face challenges with artifactual results due to cell viability issues in in vitro assays.
Existing assays may not fully capture the complex in vivo immune cell functions.

Purpose of the Study:

To review and discuss novel strategies for immunotoxicity assessment.
To present an improved method for T-cell activation that mitigates viability artifacts.
To explore the utility of adoptive transfer for integrating in vitro and in vivo immune assays.

Main Methods:

Development of an in vivo T-cell activation method bypassing in vitro viability artifacts.
Application of adoptive transfer techniques to study natural killer cell function.

Discussion of integrating in vitro metabolic activation with other immunological assays.

Main Results:

The proposed in vivo T-cell activation method effectively circumvents viability-related artifacts.
Adoptive transfer strategies offer a way to combine in vitro cell manipulation with in vivo functional assessment.
The necessity of an in vitro metabolic activation step prior to other immunologic assays is highlighted.

Conclusions:

Novel approaches enhance the reliability and accuracy of immunotoxicity testing.
Combining in vitro and in vivo methods, particularly with adoptive transfer, provides a more comprehensive assessment of immune function.
Integrating metabolic activation is crucial for accurate in vitro immunologic evaluations.
