Active Immunity – antibodies that develop in a person’s own immune system after the body is exposed toRead More →
Innate immune cells are white blood cells that mediate innate immunity and include basophils, dendritic cells, eosinophils, Langerhans cells, mast cells, monocytes and macrophages, neutrophils and NK cells. Are CD4 cells innate or adaptive? Direct activation of TLR signaling in effector/memory CD4+ T cells induces innate-like effector function (Fig. 2).Read More →
