Canonical phospholipase D isoforms in visual function and ocular response to stress

Area of Science:

• Biochemistry
• Cell Biology
• Ophthalmology

Background:

• Classical phospholipase D (PLD) isoforms, PLD1 and PLD2, generate lipid messengers like phosphatidic acid (PA) and diacylglycerol (DAG).
• The PLD pathway influences critical cellular events including proliferation, membrane trafficking, autophagy, and inflammatory responses.

Purpose of the Study:

• To review the role of canonical PLD isoforms in physiological and pathological ocular responses.
• To explore the therapeutic potential of targeting the PLD pathway in various eye conditions.

Main Methods:

• Literature review summarizing existing research on PLD1 and PLD2 in ocular biology.
• Analysis of studies investigating the effects of PLD modulation on ocular stress, inflammation, and healing.

Main Results:

• The PLD pathway's role in ocular stress responses requires further elucidation.
• Pharmacological inhibition of PLD enzymes may prevent retinal inflammation, abnormal ocular surface proliferation, and pathological neovascularization.
• Modulating classical PLDs could enhance corneal healing processes.

Conclusions:

• Understanding PLD1 and PLD2's function in ocular diseases offers new therapeutic strategies.
• Targeting PLD offers potential for treating inflammatory and degenerative eye conditions.
