Abstract:
Mediators involving in inflammation induction and regulation have been investigated as biomarkers for severe joint pain induced by chikungunya virus (CHIKV) infection. In this report, observational study was conducted to determine levels of an antagonist of interleukin-1 receptor (IL-1Ra) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in CHIKV patients with different disease severity. CHIKV infection patients presented without (n = 199) and with joint pain (n = 262) were included. IL-1Ra and sVCAM-1 levels in patient sera were determined. Levels of sVCAM-1 were strongly and significantly higher in the group of patients with joint pain than in the group without joint pain (p < 0.0001). The levels of both IL-1Ra and sVCAM-1 were not significantly increased with age.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
