Research Applications
Immune Modulation
Studied extensively for immunoregulatory activity:
- T-cell maturation — thymic differentiation research
- NK-cell function — innate immunity models
- Immune balance — Th1/Th2 signaling
Antiviral Immunity
Examined in viral-response research:
- Hepatitis models — chronic viral immunology
- Antiviral signaling — interferon-linked pathways
- Immune reconstitution — host-defense research
Oncology & Adjunct Research
Investigated as an immunomodulatory adjunct:
- Tumor immunology — T-cell response models
- Adjunct research — combination immunology
Vaccine & Host Response
Explored for immune enhancement:
