The results of this review suggest that TNF activity measured by TNF[alpha], sTNFR1 and sTNFR2 could be related to the length of illness, the number of episodes and changes to the cognitive function in adult patients with BD during euthymia.
The objectives of this study were: 1) To characterize the intensity of vibration stimulation in women diagnosed with FM as compared to a control group of healthy women (HW), matched by age and anthropometric parameters and 2) to investigate the effect of a single bout of WBV on inflammatory biomarker levels (adiponectin, sTNFr1, sTNFr2, resistin, leptin, BDNF, and IL-8).
In the COPD group, levels of IL-6, IL-8, sTNFR1, and sTNFR2 did not change after WBV [IL-6 (p = 0.08, df = 12); IL-8 (p = 0.25, df = 12); sTNFR-1 (p = 0.38, df = 12); and sTNFR-2 (p = 0.37, df = 12)].
Recent research results indicate that an intensive weight-loss intervention in older obese adults with knee pain can help in improving inflammatory biomarkers- interleukin 6 (IL-6), tumor necrosis factor alpha (TNFI[+ or -]), C-reactive protein, and soluble receptors for TNF1[+ or -] (sTNFR1 and sTNFR2)) and that changes in these concentrations showed associations with physical function (13).
(33) have shown, in the WBVE group compared to the control group, a significant reduction of the plasma concentrations of surface TNF-[alpha] receptors 1 and 2 (sTNFR1 and sTNFR2), a significant increase in the self-reported pain (WOMAC), balance (BBS), and gait performance (6MWT).

Since TNF-[alpha] has a short half-life, the soluble receptor sTNFR1 was chosen to indicate the activity of TNF-[alpha], because it provides more stable serum levels (20).
In vivo, BCG infection has shown that tmTNF may interact with soluble TNF receptors (sTNFR1 or sTNFR2) which may play a critical role in the infection outcome [32].
The results demonstrated that for patients with sTNFR1 levels in the highest quartile, the risk of progression to ESRD was almost 80% in 12 years.
(10) The extracellular portions of these receptors may constitute soluble forms (sTNFR1 and sTNFR2) and can be measured in the circulation.
(10), acute and chronic aerobic exercise resulted in a change in sTNFR1 and sTNFR2 levels that correlated with functional improvements in elderly women with kOA.
