Background:

Interleukin-12 (IL-12) is a cytokine with a unique heterodimeric structure.
Primarily produced by macrophages/monocytes upon stimulation, IL-12 plays a crucial role in immune responses.

Purpose of the Study:

To investigate the immunomodulatory activities of IL-12.
To evaluate the therapeutic potential of IL-12 in disease models, including parasitic infections and malignancies.

Main Methods:

Characterization of IL-12's biological functions.
Assessment of IL-12 efficacy in preclinical models of Leishmania, Toxoplasma, and murine cancers.

Main Results:

IL-12 enhances the cytolytic activity of T cells, NK cells, LAK cells, and macrophages.

It promotes T cell proliferation, interferon-gamma production, and TH1 cell induction.

IL-12 demonstrated significant activity against parasitic infections and exhibited antimetastatic and antitumor effects in murine models with minimal toxicity.

Conclusions:

IL-12 possesses potent immunomodulatory properties.
IL-12 shows therapeutic promise for treating parasitic infections and various malignancies.
Further investigation into IL-12 as a treatment modality is warranted.
