How to Collect Saliva for Cytokines


Better results begin with better saliva collection. This collection protocol features general considerations to maximize salivary Cytokine analysis. Use this saliva collection protocol to plan your collection methodology and sampling schemes.


Analyte Summary

IL-6 –

Human interleukin-6 (IL-6) is involved in numerous biological processes including inflammation, aging, cell growth, apoptosis, and bone remodeling. It is a 23.7 kDa cytokine with two disulfide bonds that is secreted mainly by T cells and macrophages and is also released from muscle cells during exercise in response to muscle contraction. IL-6 induces an acute phase response and plays an essential role in differentiating B cells into immunoglobulin-secreting cells. IL-6 is also a potent inducer of C-reactive protein in the liver. IL-6 is involved in osteoporosis, pulmonary fibrosis, liver cirrhosis, ischemia, and berylliosis, among other disorders.

IL-1 Beta –

Human interleukin-1β (IL-1β), also known as IL-1F2, is a 30.7 kDa pro-inflammatory cytokine that is produced by activated macrophages. IL-1β stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1β is involved in a number of biological activities ranging from aging to wound healing. Along with IFN-γ, IL-6, and TNF-α, IL-1β is a pyrogenic cytokine that induces the production of prostaglandins, the major mediators of fever induction. IL-1β is also strongly associated with oral inflammatory diseases including gingivitis and periodontal disease.

TNF-Alpha –

Human tumor necrosis factor alpha (TNF-α) is a potent proinflammatory cytokine that induces the classic signs of inflammation to occur locally and is one of the cytokines that make up the acute phase reaction. TNF is mainly produced by activated macrophages as a 25.6 kDa protein that forms a noncovalent homotrimer, but can also be secreted by a variety of cells. Large amounts of TNF are released in response to lipopolysaccharide and other bacterial components and interleukin-1. It is a potent chemoattractant for neutrophils. It also stimulates IL-1, which induces cachexia and causes fever. It can also induce sepsis and inflammation and can inhibit tumorigenesis and viral replication. Chronic TNF dysregulation has been associated with autoimmune diseases such as rheumatoid arthritis and inflammatory bowel disease as well as psoriasis and asthma. TNF can be inhibited by the exercise induced myokines such as IL-6 and IL-10.

IL-8 –

Human interleukin-8 (IL-8). It is an 11.1 kDa CXC family chemokine that is expressed by several cell types in response to inflammation. It attracts neutrophils, basophils, and T-cells but not monocytes and is also involved in neutrophil activation. IL-8 is secreted as a protein that is proteolytically cleaved to form several processed forms with varying activity. This proinflammatory chemokine is associated with numerous disorders including acute pancreatitis.
