Lead is a very common toxin in our environment and the human immune system can be quite sensitive to it. Lead can impair the immune system of humans and animals by means of its ability to stimulate or depress the immune system. Lead does this by impairing B cells, T cells, natural killer (NK) cells, and immune system chemicals such as cytokine, chemokines and nitric oxide (NO).
