TNFRSF1A and Sepsis: In our study, however, no significant differences between the p55 and p75 TNF-α receptor expression on neutrophils in children with thermal and mechanical injuries were observed as compared to the control group, which may demonstrate a less significant TNF-α involvement in these patients’ granulocyte activation as opposed to, e.g., children with sepsis (for whom statistically significant differences in receptor expressions as compared with the controls were recorded).
