1. FirePlex® immunoassay publications
FirePlex immunoassays are new to the scene and are starting to emerge in high-impact publications as a powerful tool for analyte profiling. FirePlex multiplexing data is helping researchers reveal immune defense mechanisms against infectious diseases, as well as pathology behind immunological dysfunction.
Laval K, Vernejoul JB, Van Cleemput J, Koyuncu OO, Enquist LW.(2018) Virulent PRV infection induces a specific and lethal systemic inflammatory response in mice. JVI.01614-18.
- FirePlex immunoassays reveal that mice with pseudorabies virus (PRV) have circulating pro-inflammatory cytokines (IL-6 and G-CSF), chemokines (Gro-1 and MCP-1) and C-reactive protein, which cause systemic neuroinflammatory symptoms and ultimately death. These findings indicate novel pathogenic mechanisms of PRV and closely related viruses such as human herpes and chickenpox viruses, providing new diagnostic and treatment opportunities.
LeFrancais E et al. (2018) Maladaptive role of neutrophil extracellular traps in pathogen-induced lung injury. JCI Insight. 3(3).
- The authors use FirePlex immunoassays to quantify pro-inflammatory cytokines (TNF-α, IL-1β, IL-10, IL-12, IFN-γ, MCP-1, and IL-6) directly from bronchoalveolar (BAL) fluid of mice (Mouse Inflammation Multiplex Immunoassay Kit), demonstrating how lung infections induce innate immune responses that damage host tissues, thereby increase susceptibility to pneumonia. Additional confirmation in human patients suggests new preventative strategies against pneumonia.
Wang L, Zhao H, Wang D. (2018) Inflammatory cytokine expression in patients with sepsis at an intensive care unit. Ex Ther Med 16: 2126-2131.
- With FirePlex immunoassays (Human Th1/Th2 (7 plex) Multiplex Immunoassay kit (ab229792) the authors discover an imbalance between Th1 and Th2 cytokine responses in ICU patients with sepsis, identifying key clinical biomarkers that might be used for novel diagnostic, prognostic and immune-targeted therapeutic tools for deadly septic shock, which is difficult to predict or treat.
Yánez DC et al. (2018) IFITM proteins drive type 2 T helper cell differentiation and exacerbate allergic airway inflammation. Eur J Immunol.
- The authors examine Th1 and Th2 cytokines in mice with FirePlex immunoassays to show that interferon-inducible transmembrane (Ifitm/Fragilis) genes skew CD4+ T cell differentiation towards Th2 polarization, and thereby cause immunopathology in allergic airway diseases.

2.1 Clinical-focused studies
Researchers are using FirePlex miRNA assays to define and utilize biomarkers across the medical landscape, from disease diagnosis to treatment selection and patient monitoring. By enabling these precision medicine approaches to clinical care, FirePlex is progressing medical capabilities against the most challenging diseases, from cancer to autoimmune disease and everything in between.
Elias KM et al. (2017) Diagnostic potential for a serum miRNA neural network for detection of ovarian cancer. Elife. 6.
- Ovarian cancer is a particularly deadly cancer, with 5-year survival rates averaging only 25-30%, due to lack of early detection methods. Most women are diagnosed only after the onset of symptoms, at which point the disease has already metastasized. Current biomarkers and early screening tests lack sensitivity, have high false positive rates and fail to detect cancers at early enough stages for successful treatment.
- To identify early biomarkers of ovarian cancer, the authors sequenced miRNAs from 179 human serum samples and utilized machine learning to identify signatures of early-stage disease. The resulting predictive algorithm was tested against 454 patients with various diagnoses and demonstrated 100% specificity for ovarian cancer. The model was further validated with FirePlex miRNA analysis of 51 clinical serum samples, demonstrating positive and negative predictive values of 91.3% and 78.6% respectively. Relevant miRNAs were expressed in pre-metastatic lesions from patients, confirming their origin and biological relevance.
- This study demonstrates the importance of FirePlex miRNA analysis as a complementary tool for biomarker identification and validation in a clinical context. The authors ultimately identify a pattern of seven circulating miRNAs that predict stage I and II ovarian cancers prior to metastasis. The highly specific signature which can discriminate between metastatic and non-metastatic forms of disease may be developed into non-invasive early screening tests to vastly improve ovarian cancer survival rates. In addition, these miRNA may reveal important biological process that contribute to early cancer growth, providing targets for more effective treatment.
Leng Q, Wang Y, Jiang F. (2018) A Direct Plasma miRNA Assay for Early Detection and Histological Classification of Lung Cancer. Transl Oncol. 2018 Aug;11(4):883-889.
- Early detection and subclassification of lung cancers is essential to improve patient prognoses and survival rates with personalized and earlier interventions. For example, if detected during Stage IA, the 5-year survival rate is 85%, compared to only 10% if detected in Stage IV. Meanwhile different subtypes of disease have differential response rates, overall survival, and toxicity profiles from certain therapies.
- FirePlex miRNA assays were utilized to quantify 11 tumor-associated miRNAs directly from 20 µL of plasma of 56 lung cancer patients and 28 cancer-free control patients. Two miRNA were identified as diagnostic markers of lung cancer, with the ability to distinguish between squamous cell carcinomas and lung adenocarcinomas. In other studies, these biomarkers are reported to contribute to disease development and progression and regulate tumor cell susceptibility to immune attack and radiation treatments.
- The authors show that FirePlex miRNA assays offer a preferred method to quickly and easily profile low-abundance miRNAs directly from plasma, whereas other miRNA profiling technologies require prohibitively large plasma volumes and complex downstream processing, which can skew results and lead to poor diagnostic performance of chosen biomarkers. The study derives a predictive miRNA signature that is easily assessed by simple blood draw, representing a promising non-invasive diagnostic tool for earlier lung cancer screening and precise subtype classification to personalize treatments and improving patient outcomes.
Our head-to-head comparison of the FirePlex Assay and qRT-PCR demonstrates that the FirePlex can eliminate intra-assay variables and improve reliability of miRNA quantification by directly targeting crude plasma and minimizing the complicated workflow.

Flowers E et al. (2015). Circulating microRNA-320a and microRNA-486 predict thiazolidinedione response: Moving towards precision health for diabetes prevention. Metabolism S20026-0495(15)00156-0.
- Current limitations in identifying individuals with insulin resistance prevent early interventions to thwart disease progression, limiting preventive measures against downstream diseases including type 2 diabetes, cardiovascular disease, cancers, polycystic ovarian syndrome, and non-alcoholic fatty liver. Meanwhile, thiazolidinediones (TZDs) can improve insulin sensitivity and stave off type 2 diabetes, but also has adverse side effects and variable response rates which limit its clinical use. Tools to select patients likely to respond to TZDs, or to exclude patients at high risk of adverse events, would significantly improve TZD’s clinical utility against the growing epidemic of metabolic syndrome.
- FirePlex miRNA analysis of 25 different miRNAs previously implicated in type 2 diabetes, insulin and glucose metabolism revealed five differentially expressed miRNAs between in the blood of insulin-resistant vs. sensitive patients. Of insulin resistant patients given TZDs, 6 miRNAs were differentially expressed between responders vs. non-responders.
- These miRNA signatures provide critical tools for early screening and detection of metabolic disease and downstream comorbidities, identifying patients prior to developing serious illness for more effective preventive interventions. In addition, these signatures will improve the success of TMZ intervention by stratifying patient populations into responders and non-responders, while excluding those at risk of drug complications.
- These biomarkers may also point to specific downstream diseases, reflecting disease heterogeneity and unique pathological mechanisms. As such, they might have clinical utility in identifying patients at risk of cardiovascular disease versus fatty liver, etc., thereby guiding individualized disease prevention and monitoring at early Stages. These early disease-specific biomarkers may also reveal molecular pathways of disease progression, identifying novel therapeutic targets for preventative treatments.

Dudics S, Venkatesha S, Moudgil K. (2018) The Micro-RNA Expression Profiles of Autoimmune Arthritis Reveal Novel Biomarkers of the Disease and Therapeutic Response. Int. J. Mol. Sci. 19(8):2293.
- Current treatments for rheumatoid arthritis have serious side effects and are only effective in about half of patients, necessitating better biomarkers for predicting and monitoring individual patient responses, and understanding of underlying mechanisms of disease pathogenesis and treatment response.
- In this study, FirePlex miRNA profiling of immune cells and serum in a rat model of rheumatoid arthritis reveals 8 novel biomarkers that point to inflammatory disease pathways. Six of these are indicative of molecular response to celastrol, an anti-inflammatory modulator, revealing novel targets of this drug.
- This is the first study to comprehensively analyze miRNA expression profiles in the context of autoimmune arthritis, providing insight into disease pathogenesis, novel therapeutic targets and potential biomarkers of human disease progression and treatment response. These discoveries open new avenues for improving diagnostic, prognostic and therapeutic tools against RA with non-invasive serum biomarker testing.

- Huntington’s disease (HD) is a neurodegenerative disease for which there are few prognostic indicators or effective treatments available. MiRNA dysregulation may impact disease progression and severity, and if so, could provide the opportunity to utilize miRNA biomarkers for disease assessment, prognosis, and development of new treatments.
- FirePlex analysis of postmortem human brain tissue revealed differential expression of 75 miRNAs in HD brains. Nine of these associated with the most severe disease pathology, five of which correlated to age of disease onset, including miR-10b-5p as the strongest indicator.
- Biomarkers of interest point to nervous system development processes and transcriptional regulation thereof, identifying critical disease pathways and novel therapeutic targets. If present in blood, urine or other biofluids, these biomarkers may be utilized for diagnostic and prognostic tests to determine disease stage, rate of progression and other important clinical characteristics of HD.
Lopez JP et al. (2017) MicroRNAs 146a/b-5 and 425-3p and 24-3p are markers of antidepressant response and regulate MAPK/Wnt-system genes. Nature Communications 8, Article number: 15497
- The antiquated trial-and-error approach to antidepressant selection leaves millions of patients suffering for months to years or longer in the search for effective treatments. For nearly 70% of patients their first drug fails, while 30-40% suffer multiple drug failures before finding a successful treatment. Biomarker indicators of drug response are desperately needed to get the right drugs the right patients, within a reasonable timeframe.
- FirePlex analysis of blood samples from patients treated with duloxetine, a serotonin-norepinephrine reuptake inhibitor, revealed 4 miRNA transcripts that were differentially expressed in patients who responded to this treatment. These biomarkers were confirmed in two independent clinical trials, post-mortem human brains, and animal models of depression. Experiments in human neural progenitor cells indicate that these miRNAs regulate dozens of genes within the MAPK/Wnt signaling pathway, many of which are involved in neurotropic factor signaling and neuronal plasticity, proliferation, survival, differentiation and synaptic function.
- These miRNA biomarkers, which are expressed ubiquitously in brain, blood, and other biofluids, could finally provide the critical tools for targeting specific antidepressant drugs to the right patients. These miRNAs, and the genes that they regulate could be relevant in duloxetine response, and other antidepressant drugs and classes with similar underlying etiologies. Using these biomarkers for antidepressant selection and monitoring could spare millions of patients the time, cost and negative side effects of ineffective treatments on the often long and frustrating road to recovery.
- These biomarkers also point to underlying disease processes and psychiatrically relevant signaling pathways that will help scientists to better understand the disease and design more effective targeted treatments.

2.1.6 Cardiovascular Disease
Shah R et al. (2018) MicroRNAs Associated With Reverse Left Ventricular Remodeling in Humans Identify Pathways of Heart Failure Progression. Circulation: Heart Failure. 11:e004278
- Circulating plasma miRNAs are important indicators of biological processes central to cardiovascular disease and heart failure, including myocardial fibrosis, atherosclerosis, and arrhythmia, pointing to diverse pathological mechanisms like hypertrophy, inflammation, autophagy, and apoptosis. Multiplex miRNA profiling is essential to understand these complex and diverse factors, to develop better risk assessment tools and targeted treatments for heart disease.
- FirePlex miRNA profiling of blood samples from patients with chronic heart disease before and after treatment reveals a cluster of miRNA transcripts that correlate with improved echocardiograms—a prognostic measure of heart disease-- and reversal of disease. These miRNAs, involved in autophagy, metabolism and inflammation processes, are dysregulated within heart tissue in mouse and cell culture models, confirming their functional role in disease.
- This study establishes a novel translational paradigm for pathway discovery in heart disease, uncovered novel miRNA, target genes and pathways involved in cardiac injury that could serve as new therapeutic targets. These biomarkers may alert clinicians to early stages of disease before significant damage occurs, and/or select the highest risk patients for more aggressive prevention and surveillance. Already, the biomarker signature identified here is a better predictor of patient response to treatment than current clinical risk parameter standards.

Glineur SF et al. (2016) Paving the Route to Plasma miR-208a-3p as an Acute Cardiac Injury Biomarker: Preclinical Rat Data Supports Its Use in Drug Safety Assessment. Toxicological Sciences 149 (1): 89–97
- Cardiac toxicity is a leading cause of pre-clinical and clinical drug failures and accounts for 45% of drug withdrawals from the market— costing exorbitant amounts of time, money and human lives. This is due to inadequate methods to screen for cardiac injury, with current standards lacking sensitivity and specificity. Despite significant investments by the pharmaceutical industry, early predictive markers of cardiac safety remain elusive and one of the greatest challenges to drug development success.
- The authors examined a panel of 68 miRNA, all previously reported in human or rodent cardiac injury, in serum from rats treated with the cardiotoxic agents isoproterenol (ISO) or allylamine (AAM). FirePlex analysis revealed 11 potential cardiotoxicity biomarkers, which were all, except one, eliminated as viable candidates for wide fluctuations over time. The remaining candidate, miR-208a-3p, detected cardiac injury severity and magnitude with equivalent or better sensitivity and specificity as the current gold standard.
- miR-208a-3p is a strong candidate for improving drug safety screening with a highly sensitive and cardiac injury specific early biomarker. Encoded by the α-cardiac muscle myosin heavy chain 6 gene, it is exclusively expressed in heart tissue where it plays a vital role in cardiac conduction. It is also highly conserved between human and rat, providing essential pre-clinical to clinical translational utility. As a circulating biomarker, it can easily be translated into non-invasive and cost-effective testing in the context of both pre-clinical and clinical trials, ultimately saving extensive amounts of time, money and lives in the quest for new medicines.

4. FirePlex Particle Technology Publications
The FirePlex particle technology employs encoded hydrogel particles to provide the highest performance in multiplex biomarker detection. Read more about how this technology works, and how it has transformed miRNA and protein profiling capabilities.
The innovative FirePlex particle technology was conceptualized and created by Dr. Daniel Pregibon. The platform emerged from Pregibon’s PhD thesis at MIT, where he combined photolithography, used to build computer chips, with modern microfluidics techniques to generate customizable microgel particles for biological applications. The ground-breaking new technology promised to revolutionize personalized medicine with fast, easy and affordable biomarker testing; the seminal work was published in the journal Science.
While at MIT, the project was supported by multiple industry partners, as well as MIT’s Deshpande Center for Technological Innovation. Building off the academic success of the platform, Pregibon aimed to commercialize the technology by co-founding Firefly BioWorks, Inc., where he served as President and Chief Technology Officer. The company was awarded multiple grants from the National Cancer Institute and National Institute of Allergies and Infectious Disease at NIH, as well as Massachusetts Life Sciences Center, with a focus on early disease detection. With support from these grants and angel investment, Firefly BioWorks developed and commercialized the first assay capable of detecting circulating miRNA biomarkers directly from crude sample digests.
In 2015, Abcam acquired Firefly Bioworks to extend breadth of content offered on the platform, creating the FirePlex product line. Pregibon continues to impart his expertise, advancing the capabilities and impact of his revolutionary platform as General Manager of Platform Innovation at Abcam.
