    A polyvalent bacterial lysate, IRS 19, effectively stimulates interferon (IFN) production in human and mouse immune cells. This immune modulator shows a biphasic release pattern of IFN in vitro.

    Area of Science:

    • Immunology
    • Virology
    • Cell Biology

    Context:

    • Investigating the immunomodulatory effects of bacterial lysates.
    • Understanding interferon induction mechanisms in immune cells.
    • Utilizing peripheral mononuclear leukocytes from human and mouse models.

    Purpose:

    • To determine if polyvalent bacterial lysate (IRS 19) can induce interferon (IFN) production.
    • To characterize the kinetics of IFN release upon stimulation.
    • To compare IFN induction in human and mouse leukocyte systems.

    Summary:

    • Polyvalent bacterial lysate (IRS 19) induces significant interferon production in peripheral mononuclear leukocytes from both humans and mice.
    • Stimulated cells produced 1000-2000 IU/ml of IFN over 72 hours.

  • Interferon release occurred in two distinct waves: early (1-4 hours) and late (beyond 16 hours), with the latter showing a tenfold increase.

    • Impact:

    • Demonstrates the potential of IRS 19 as an interferon inducer.
    • Provides insights into the conserved mechanisms of immune response to bacterial lysates across species.
    • Highlights the utility of IRS 19 in immunological research and potential therapeutic applications.
