Zinc deficiency, defined as a plasma zinc concentration <9.95 mmol/L, in Indonesian infants was accompanied by lower production of IL-6 after ex vivo stimulation of whole blood with LPS and PHA [33], while no significant differences between zinc-sufficient and zinc-deficient adults were observed in the production of IL-6 in PBMC stimulated with PHA alone [29]. The gene discussed is IL6; the disease is Zinc deficiency.
