Abstract
Skeletal muscle extracellular matrix (ECM) is critical for muscle force production and the regulation of important physiological processes during growth, regeneration, and remodelling. ECM remodelling is a tightly orchestrated process, sensitive to multi-directional tensile and compressive stresses and damaging stimuli, and its assessment can convey important information on rehabilitation effectiveness, injury, and disease. Despite its profound importance, ECM biomarkers are underused in studies examining the effects of exercise, disuse, or aging on muscle function, growth, and structure. This review examines patterns of short- and long-term changes in the synthesis and concentrations of ECM markers in biofluids and tissues, which may be useful for describing the time course of ECM remodelling following physical activity and disuse. Forces imposed on the ECM during physical activity critically affect cell signalling while disuse causes non-optimal adaptations, including connective tissue proliferation. The goal of this review is to inform researchers, and rehabilitation, medical, and exercise practitioners better about the role of ECM biomarkers in research and clinical environments to accelerate the development of targeted physical activity treatments, improve ECM status assessment, and enhance function in aging, injury, and disease.

The detection and measurement of interleukin-6 in venous and capillary blood samples, and in sweat collected at rest and during exercise. Eur J Appl Physiol 2014; 114:1207-16. [PMID: 24577845 DOI: 10.1007/s00421-014-2851-8] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2013] [Accepted: 02/12/2014] [Indexed: 11/26/2022]
Abstract
PURPOSE This study aimed to quantify the relationship between venous and capillary blood sampling methods for the measurement of plasma interleukin-6 (IL-6). A parallel study was conducted to determine the possibility of measuring IL-6 in sweat using an enzyme-linked immunosorbent assay (ELISA) and investigate the relationship between plasma- and sweat-derived measures of IL-6. METHODS Twelve male participants were recruited for the measurement of IL-6 at rest and during exercise (study 1). An additional group of five female participants was recruited for the measurement of IL-6 in venous blood versus sweat at rest and following exercise (study 2). In study 1, venous and capillary blood samples were collected at rest and in response to exercise. In study 2, venous and sweat samples were collected following exercise. RESULTS Mean plasma IL-6 concentration was not different between venous and capillary blood sampling methods either at rest (4.27 ± 5.40 vs. 4.14 ± 4.45 pg ml(-1)), during (5.40 ± 5.17 vs. 5.58 ± 6.34 pg ml(-1)), or in response to exercise (6.95 ± 6.37 vs. 6.99 ± 6.74 pg ml(-1)). There was no IL-6 detectable in sweat either at rest or following exercise. CONCLUSION There are no differences in the measurement of plasma IL-6 using either venous or capillary blood sampling methods. Capillary measurement represents a minimally invasive way of measuring IL-6 and detecting changes in IL-6, which are linked to fatigue and overtraining.

Elevated neuroimmune biomarkers in sweat patches and plasma of premenopausal women with major depressive disorder in remission: the POWER study. Biol Psychiatry 2008; 64:907-11. [PMID: 18657799 PMCID: PMC2610843 DOI: 10.1016/j.biopsych.2008.05.035] [Citation(s) in RCA: 136] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2007] [Revised: 05/19/2008] [Accepted: 05/30/2008] [Indexed: 12/24/2022]
Abstract
BACKGROUND Major depressive disorder (MDD) is inconsistently associated with elevations in proinflammatory cytokines and neuropeptides. We used a skin sweat patch, recently validated in healthy control subjects, and recycling immunoaffinity chromatography to measure neuroimmune biomarkers in patients with MDD mostly in remission. METHODS We collected blood at 8:00 am and applied skin sweat patches for 24 hours in 21- to 45-year-old premenopausal women (n = 19) with MDD (17/19 in remission) and age-matched healthy controls (n = 17) participating in the POWER (Premenopausal, Osteopenia/Osteoporosis, Women, Alendronate, Depression) Study. RESULTS Proinflammatory cytokines, neuropeptide Y, substance P, and calcitonin-gene-related peptide were significantly higher and vasoactive intestinal peptide, a marker of parasympathetic activity, was significantly lower in patients compared to controls, and depressive symptomatology strongly correlated with biomarker levels. All analytes were strongly correlated in the skin sweat patch and plasma in patients (r = .73 to .99; p < .0004). CONCLUSIONS The skin sweat patch allows detection of disrupted patterns of proinflammatory cytokines and neuropeptides in women with MDD in clinical remission, which could predispose to medical consequences such as cardiovascular disease, osteoporosis, and diabetes. This method permits measurement of cytokines in ambulatory settings where blood collection is not feasible.

J Immunol Methods 2006; 315:99-109. [PMID: 16942779 DOI: 10.1016/j.jim.2006.07.011] [Citation(s) in RCA: 62] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2006] [Revised: 07/12/2006] [Accepted: 07/17/2006] [Indexed: 11/25/2022]
Abstract
Cytokines have been detected by ELISA in a variety of body fluids. Recycling immunoaffinity chromatography (RIC) coupled with laser-induced fluorescence detection is a highly sensitive and specific method, which allows simultaneous measurements of many analytes in small volumes of biological fluids. This method has been applied to plasma, cervical secretions and other body fluids, but has not previously been applied to sweat. The aim of this study was to validate the RIC methodology in sweat for measurements of IL-1alpha, IL-1beta, IL-6, TNF-alpha, IL-8 and TGF-beta. Two sweat patches were applied for 24 h on the torso, and blood was collected at one time point during this period in nine healthy women. Cytokines were measured in paired samples of plasma and sweat. Cytokines were detected in sweat in similar concentrations to plasma. Linear regression analysis confirmed that sweat levels of these cytokines accounted for a large percentages of variance in plasma levels: IL-1alpha (R2 = 0.70, p = 0.005), IL-1beta (R2 = 0.79, p = 0.003), IL-6 (R2 = 0.52, p = 0.03), TNF-alpha (R2 = 0.95, p < 0.0001), IL-8 (R2 = 0.81, p = 0.001) and TGF-beta (R2 = 0.94, p = 0.0003). These findings indicate that cytokine levels measured in sweat are informative of circulating levels and that sweat patches combined with RIC represents a viable non-invasive method to measure cytokines in ambulatory settings over time. This method is unobtrusive and requires minimal active compliance on the part of the subjects being studied, without pain or stress. This approach can open a new generation of studies to address the effects of environmental factors on immune responses in a wide range of different settings.
