Stress response of the trabecular meshwork

Area of Science:

• Ophthalmology
• Cell Biology
• Biomedical Engineering

Background:

• The trabecular meshwork (TM) is crucial for regulating intraocular pressure.
• TM cells face mechanical, oxidative, and phagocytic stress.
• Chronic stress can alter TM physiology, increasing resistance to aqueous humor outflow, a hallmark of glaucoma.

Purpose of the Study:

• To review the TM's responses to various stressors.
• To explore the role of these responses in TM dysfunction in aging and glaucoma.
• To identify potential therapeutic targets for glaucoma.

Main Methods:

• Literature review of studies on TM stress responses.
• Analysis of research on gene and protein expression changes in TM.
• Examination of signal transduction pathways involved in TM stress response.

Main Results:

• Short-term stress can induce adaptive responses in TM.
• Long-term stress leads to permanent TM alterations and increased outflow resistance.
• Stress-induced TM changes are implicated in aging and glaucoma pathogenesis.

Conclusions:

• Understanding TM stress responses is vital for glaucoma research.
• Targeting TM stress pathways may offer novel therapeutic avenues for glaucoma.
• Further research into cell-specific and tissue-specific responses is warranted.
