AI-generated summary by claude@2026-06, 2026-06-07

This study found that TNF-α and TNFR2 levels, along with TNFR2-bearing cells, increased with endometriosis severity, while TNFR1 levels and TNFR1-bearing cells decreased.

This study analyzed TNF-α, TNFR1, and TNFR2 gene expression in peritoneal fluid mononuclear cells (PFMCs) from 80 women with endometriosis across minimal, mild, moderate, and severe stages, measuring both mRNA and protein levels, the proportions of PFMCs bearing these markers, and soluble TNF-α (sTNF-α) in peritoneal fluid. TNFR1 mRNA/protein, TNFR1-bearing PFMC percentages, and sTNF-α decreased with advancing disease stage, while TNF-α and TNFR2 mRNA/protein and the percentages of membrane TNF-α and TNFR2-bearing PFMCs increased as disease worsened. The authors interpret stage-dependent shifts as potentially favoring different TNF receptor signaling outcomes (including inflammatory versus death-related processes), while noting that these interpretations are presented as hypotheses based on observed expression patterns. This paper is centrally about endometriosis — it characterizes how the TNF-α/TNFR1/TNFR2 system in peritoneal mononuclear cells changes across disease stages.

Abstract

During endometriosis, a breakdown occurs in endometrial and peritoneal homeostasis caused by cytokine-induced cell proliferation and dysregulation of apoptosis. We studied tumor necrosis factor (TNF)-α, TNF receptor (TNFR) 1, and TNFR2 gene expression at both messenger RNA (mRNA) and protein levels in peritoneal fluid (PF) mononuclear cells (PFMCs), the percentages of these cells bearing the same markers, and soluble TNF-α (sTNF-α) values in PF of 80 women with endometriosis. We found that TNFR1 mRNA and protein levels, the percentages of TNFR1-bearing PFMCs, and sTNF-α values decreased from minimal to severe stages of the disease. Instead, TNF-α and TNFR2 mRNA and protein levels, the percentages of membrane TNF-α (mTNF-α)- and TNFR2-bearing PFMCs increased as the disease worsened. These data allow us to hypothesize that, in early stages, the high percentages of TNFR1-bearing PFMCs and the high levels of sTNF-α could address signal toward complex I pathway, favoring the inflammatory response. With the worsening of the disease, the low percentages of TNFR1-bearing PFMCs are probably due to decreased TNFR1 mRNA transcription and protein translation rate. In early stages (minimal and mild), the percentages of both TNFR2- and mTNF-α-bearing PFMCs are so low, due to decreased mRNA transcription and protein translation rate, that subsequent cellular events may depend minimally by this interaction. The high levels of sTNF-α may be rerouted to bind TNFR1. In contrast, in the moderate and severe stages, the high percentages of TNFR2-bearing PFMCs may be saturated by high percentages of mTNF-α-bearing PFMCs, triggering death process. So, in endometriosis, each component of the TNF-α/TNFRs system may trigger opposite cellular fate.
