demonstrated that D. peregrina‐mediated immunomodulation of lymphocytes isolated from the blood of breast cancer patients promotes lymphocytic proliferation, induces type 1 cytokines (IL‐12 (interleukin‐12), IFN‐γ (interferon gamma)), and produces the tumor‐killing agent nitric oxide (NO) (Roy et al., 2021). The gene discussed is IFNG; the disease is neoplasm.
