Relationship between TLR4 and MCP2 expression levels and habitual abortion

Area of Science:

• Reproductive immunology
• Genetics and gene expression

Background:

• Habitual abortion is linked to genetic factors.
• Toll-like receptor 4 (TLR4) and monocyte chemotactic protein 2 (MCP2/CCL8) are key immune response genes.
• Their role in habitual abortion requires further investigation.

Purpose of the Study:

• To investigate the relationship between TLR4 and MCP2 expression and habitual abortion.
• To compare gene expression in patients versus healthy controls.
• To assess the potential of these genes as biomarkers for habitual abortion.

Main Methods:

• Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used.
• Expression levels of TLR4 and MCP2 were measured in peripheral blood and placental villi.
• GAPDH served as the reference control.

Main Results:

• TLR4 and MCP2 expression were significantly higher in habitual abortion patients compared to controls (P < 0.05).
• A positive correlation was found between TLR4 and MCP2 expression levels.
• Increased expression was observed in both peripheral blood and placental villi.

Conclusions:

• TLR4 and MCP2 expression levels are correlated with habitual abortion.
• Measuring TLR4 and MCP2 expression in peripheral blood is a viable method for predicting abortion risk.
• These findings offer potential diagnostic markers for women at risk of habitual abortion.
