Area of Science:

Immunology
Cellular immunology
Hypersensitivity research

Background:

Delayed-type hypersensitivity (DTH) is a critical in vivo assay for evaluating cell-mediated immune function.
DTH responses involve distinct sensitization and efferent phases, typically occurring 6-14 days post-immunization.
Understanding DTH mechanisms is vital for diagnosing and treating immune-related disorders.

Purpose of the Study:

To provide a detailed protocol for stimulating DTH responses in a murine model.
To establish a reproducible method for inducing DTH using a specific hapten.
To facilitate research into the cellular mechanisms underlying DTH.

Main Methods:

The protocol involves sensitizing mice with a specific antigen.
The efferent phase is initiated by challenging sensitized mice.

The hapten 4-hydroxy-3-nitrophenyl acetyl O-succinimide ester (NP-O-Su) is used for immunization.

Main Results:

The described protocol successfully stimulates DTH responses in mice.
The method allows for the study of DTH kinetics following sensitization.
NP-O-Su serves as an effective antigen for inducing DTH in this model.

Conclusions:

This unit presents a standardized protocol for DTH induction in mice.
The protocol enables reliable investigation of cell-mediated immunity.
The method is valuable for immunological research and DTH studies.
