Human Erythropoietin (EPO) is also known as EP, erythropoetin or erthropoyetin, and is a glycoprotein hormone that controls erythropoiesis, or red blood cell production. EPO is a cytokine for erythrocyte (red blood cell) precursors in the bone marrow. is synthesized by renal peritubular cells in adults, with a small amount being produced in the liver. Regulation is believed to rely on a feed-back mechanism measuring blood oxygenation. Constitutively synthesized transcription factors for EPO, known as hypoxia-inducible factors (HIFs), are hydroxylated and proteosomally digested in the presence of oxygen. It binds to the erythropoietin receptor (EpoR) on the red cell surface and activates a JAK2 cascade. Erythropoietin has its primary effect on red blood cells by promoting red blood cell survival through protecting these cells from apoptosis. It also cooperates with various growth factors involved in the development of precursor red cells. EPO has a range of actions including vasoconstriction-dependent hypertension, stimulating angiogenesis, and inducing proliferation of smooth muscle fibers. It has also been shown that erythropoietin can increase iron absorption by suppressing the hormone hepcidin. Erythropoietin has been shown to interact with the Erythropoietin receptor as its mechanism of action within the body. erythropoietin plays an important role in the brain's response to neuronal injury. EPO is also involved in the wound healing process.

VACUETTE® tubes contain sodium citrate solutions in concentrations of 3,2% or 3,8% and are used for assays in haemostaseology. The mixing of 9 parts blood to 1 part sodium citrate takes place immediately after the blood is drawn by inverting the tube, causing anticoagulation through the binding of calcium.

Interleukin 4 (IL-4) is a type I cytokine produced by Th2 T cells, NK T cells, γ/δ T cells, eosinophils, mast cells, and activated basophils. IL-4 receptors are present on a number of cells, including hematopoietic, endothelial, epithelial, muscle, and brain tissues. IL-4 receptor engagement initiates signaling through the JAK/STAT pathway, and leads to the activation of PI3K and Ras/MAPK pathways (Nelms et al.). IL-4 plays a key role in immunoglobulin class switching in B cells and in regulating the differentiation of naïve T cells into T helper 2 (Th2) cells, while inhibiting Th1 differentiation. IL-4 acts together with tumor necrosis factor to stimulate expression of adhesion molecules on vascular endothelial cells and to downregulate expression of E-selectin, thus recruiting T cells and eosinophils to the site of inflammation (Nelms et al.).

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is also known as Colony stimulating factor 2 (granulocyte-macrophage), is a cytokine initially characterized by its ability to induce colonies of granulocytes and macrophages from myeloid progenitor cells, and is secreted by macrophages, T cells, mast cells, endothelial cells and fibroblasts. GM-CSF is a cytokine that functions as a white blood cell growth factor. GM-CSF stimulates stem cells to produce granulocytes (neutrophils, eosinophils, and basophils) and monocytes. Monocytes exitthe circulation and migrate into tissue, whereupon they mature into macrophages and dendritic cells. Thus, it is part of the immune/inflammatory cascade, by which activation of a small number of macrophages can rapidly lead to an increase in their numbers, a process crucial for fighting infection. The active form of the protein is found extracellularly as a homodimer. Human GM-CSF glycosylated in its mature form. As a part of the immune/inflammatory cascade, GM-CSF promotes Th1 biased immune response, angiogenesis, allergic inflammation, and the development of autoimmunity, and thus worthy of consideration for therapeutic target. GM-CSF has also recently been evaluated in clinical trials for its potential as a vaccine adjuvant in HIV-infected patients. The preliminary results have been promising. GM-CSF is also used as a medication to stimulate the production of white blood cells following chemotherapy.
