|August 19, 2014
Summary
Adenosine and nucleotides play key roles in eye inflammation. Targeting purinergic receptors with agonists or antagonists offers potential therapies for inflammatory eye diseases.
Area of Science:
- Ocular immunology
- Neuroinflammation
- Purinergic signaling
Background:
- Ocular inflammation can cause severe visual organ disorders.
- Adenosine and nucleotides (ADP, ATP, Ap4A, Ap5A) are present in ocular tissues.
- These molecules may modulate ocular inflammatory processes.
Purpose of the Study:
- To investigate the role of adenosine and nucleotides in ocular inflammation.
- To explore the therapeutic potential of targeting purinergic receptors for inflammatory eye conditions.
Main Methods:
- Review of existing literature on purinergic signaling in the eye.
- Analysis of adenosine receptor functions (A2A, A3) in retinal inflammation.
- Examination of ATP-mediated P2 receptor activation in ocular tissues.
Main Results:
- A2A adenosine receptors exhibit anti-inflammatory effects in retinal inflammation.
- A3 receptor agonists (e.g., CF101) are used to treat dry eye and uveoretinitis.
- ATP can activate P2 receptors, potentially leading to uveitis/endophthalmitis.
Conclusions:
- Adenosine and nucleotides activate receptors in ocular structures prone to inflammation.
- Purinergic agonists and antagonists represent promising therapeutic targets for ocular inflammation.

01:27Open Angle Glaucoma: Treatment
1.0K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:22Microbiome of the Eye
67
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

01:23Ophthalmic Drug Delivery Systems
278
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

01:25Acute Inflammation II: Local and Systemic Effects
45
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...

01:25Glaucoma: Overview
1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:25Cholinergic Receptors: Muscarinic
4.9K
The pharmacological actions of acetylcholine are elicited via its binding to two families of cholinergic receptors or cholinoceptors, namely, muscarinic and nicotinic receptors. Muscarinic receptors are G protein-coupled receptors and have five subtypes, M1–M5. All mAChR subtypes are activated by acetylcholine and blocked by the antagonist, atropine.
The subtypes M1, M3, and M5 couple with the Gq subunit and activate the phospholipase C (PLC) activity, mobilizing intracellular Ca2+....
