TNF and neoplasm: Moreover, activation of PLA2 by Melittin[33] further enhanced trained immunity (Figures 5h,i), whereas inhibition of PLA2 by 1‐naphthylacetic acid (NAA) partially attenuated reuterin‐induced trained immunity,[34] as reflected by a reduction, but not a complete loss, in the tumor cell‐killing capacity, TNF‐α, and NO production (Figure 5j,k, Figure S7i, Supporting Information).
