TMEM176A and TMEM176B Are Candidate Regulators of Inhibition of Dendritic Cell Maturation and Function after Chronic Spinal Cord Injury

JOURNAL OF NEUROTRAUMA, 2020 · DOI: 10.1089/neu.2019.6498 · Published: February 1, 2020

Simple Explanation

This study explores the role of two genes, TMEM176A and TMEM176B, in the immune response following chronic spinal cord injury (SCI). These genes are known to be involved in the maturation of dendritic cells, which are important for immune function. The researchers found that these genes were overexpressed in individuals with chronic SCI, suggesting that they may be involved in suppressing the immune system's ability to promote neuroprotection and recovery after SCI. By identifying these candidate genes, the study opens up new avenues for developing therapies that can modulate the immune system to improve outcomes for individuals with SCI.

Study Duration

Key Findings

1
TMEM176A and TMEM176B are significantly elevated in circulating monocytes from subjects with chronic SCI.
2
Microarray analysis showed TMEM176A and TMEM176B genes to be overexpressed by factors of 5.2 (p = 0.01) and 11.9 (p = 0.01), respectively in SCI patients compared with healthy controls.
3
Quantitative real-time PCR showed that TMEM176A and TMEM176B were overexpressed 42.4 (p < 0.05) and 84.1-fold (p < 0.05) respectively, validating the microarray analysis results.

Research Summary

This study investigates the overexpression of TMEM176A and TMEM176B genes in circulating monocytes of individuals with chronic SCI, suggesting their potential role in suppressing dendritic cell function and hindering protective immune responses. Microarray and qPCR analyses confirmed significant upregulation of both genes in SCI patients compared to healthy controls, indicating their involvement in SCI-induced immune changes. The findings propose that targeting TMEM176A and TMEM176B could offer therapeutic strategies for restoring dendritic cell function, promoting neuroprotection, and improving recovery after SCI.

Practical Implications

Therapeutic Target Identification

TMEM176A and TMEM176B may serve as novel therapeutic targets for modulating immune responses in chronic SCI.

Restoration of Dendritic Cell Function

Interference with TMEM176A and TMEM176B expression or function could restore dendritic cell capacity to effectively present antigen, leading to CD4+ T cell activation and neuroprotection.

Development of Less Invasive Therapies

Targeting TMEM176A and TMEM176B could offer a less invasive alternative to dendritic cell vaccination therapy.
