Introduction Biomonitoring, or the measurement of biomarkers in biological samples, is an important aspect of public health policy. Within the United States, the National Health and Nutrition Examination Survey (NHANES) conducted by the Centers for Disease Control and Prevention (CDC) uses biomonitoring information to better assess public health. 1,2 Other countries, such as Canada, Germany, and France, also have implemented biomonitoring programs at the national level. 3 Smaller-scale studies are also conducted at a national or local level to evaluate exposure over a specific time period or exposure for specific age groups. 4–8 In addition to biomonitoring programs, clinical testing laboratories may also analyze biological samples to assess industrial exposures, monitor therapeutic levels, or to aid physicians in diagnostic evaluations of patients. Advancements in this field over the last decade have led to better understanding of how the association of metals may affect thyroid levels, prenatal exposures may lead to learning or social disabilities, the degradation of metal-on-metal implants changes over time, and increased blood lead levels may be correlated to multiple sclerosis patients. 9–13 Cytokine concentration was determined by fluorescence intensity. Fluorescence data were analyzed with Millipore Milliplex Analyst version 3.4 according to manufacturer recommendations. All statistical analyses were performed with the calculated concentrations of each sample rather than the MFI (mean fluorescence intensity) source data to give a more accurate representation of assay performance.

Cytokines transmit intracellular signals that are central to immune homeostasis or dysregulation and have a central role in pathologies like obesity and diabetes or cancer and autoimmunity. Conversely, the normal cytokine response can also be a target for immune manipulation like in the situation of transplantation where the host immune response to the graft must be suppressed to prevent rejection. In transplantation the achievement of immune tolerance reduces the risk of rejection and improves safety by eliminating toxic immunosuppression 6. Immune profiling cytokines in health and disease has led to the development of numerous immunotherapy medications, both agonists and antagonists, for many diseases such as adult and juvenile rheumatoid arthritis, psoriasis, Inflammatory Bowel Disease, melanoma, colon cancer, lung cancer, renal cell carcinoma, multiple myeloma, and AIDS. For example, Adalimumab, an anti-TNFα antibody, has been used successfully to treat Inflammatory Bowel Disease 7. IL-2 and IFNα in combination with chemotherapy have been used to treat metastatic melanoma, but development of many other cytokine treatments like IL-15 as single agents has not proceeded beyond Phase 2 trials 8. Clinical inefficacy or negative side effects have so far limited the wide clinical success of cytokine-based therapies 9, 10, which is related to cytokine signaling across multiple pathways and many that exhibit redundancy and pleiotropy. The complexity of these targets drives the need for accurate and reliable measurements of cytokines to continue to advance the understanding of immune pathophysiology and immunomodulation strategies.Millipore Milliplex MAP premixed bead-based 23-plex kits for Non-Human Primate Cytokines (#MPXPRCYTO-40K-PX23, #PCYTMG-40K-PX23) were used according to manufacturer instructions 25. Change in kit number was due to manufacturer transition in kit format from polystyrene to magnetic beads. All validation-related measures were performed using the magnetic bead-based kit. These kits includes premixed beads for 23 cytokines: G-CSG, GM-CSF, IFNγ, IL-1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12/23(p40), IL-13, IL-15, IL-17A, MCP-1, MIP-1α, MIP-1β, sCD40L, TGFα, TNFα, VEGF and IL-18. Standard curves for each cytokine were prepared by serial dilution and run in triplicate (Polystyrene Bead Kit: 0.64–10,000 pg/mL for all cytokines; Magnetic Bead Kit: IL-4: 4.9–20,000 pg/mL; IL-10 and IL-18: 12.2–50,000 pg/mL; remaining cytokines: 2.4–10,000 pg/mL). The standards and controls for nine of the cytokines (IFNγ, IL-1β, IL-2, IL-4, IL-5, IL-12, IL-13, TNFα and IL-18) were recombinant NHP proteins; the standards and controls for the other 14 cytokines were human proteins. The detecting antibodies for IL-2 were generated against monkey (unspecified species) protein; the detecting antibodies for VEGF were generated against mouse protein; the detecting antibodies for the remaining 21 cytokines were generated against human proteins. The manufacturer reports “no or negligible” cross-reactivity between any of the analytes of the assay panel. A human serum matrix provided with each assay kit is added to the standard and control wells to mimic the NHP matrix of the samples. A Luminex100 system equipped with xPONENT v. 3.1 software was used to perform the multiplexed assays. Validation assays Study design Swart DJ, Simeonsson JB.
