Complement System

Complement System

The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a membrane...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Diabetic Retinopathy

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Summary

Age-related macular degeneration (AMD) involves the complement system, a part of immunity. Targeting this system may prevent vision loss from AMD.

Area of Science:

Ophthalmology
Immunology
Genetics

Background:

Age-related macular degeneration (AMD) is a primary cause of vision loss.
The complement system, a key immune pathway, is implicated in AMD pathogenesis.
Genetic variants in complement genes are linked to AMD development.

Purpose of the Study:

To review the role of the complement system in AMD.
To explore the potential of complement inhibition as a therapeutic strategy for AMD.

Main Methods:

Literature review of studies on complement system and AMD.
Analysis of histological and circulating complement factors in AMD patients.
Examination of the interplay between oxidative stress and complement activation in AMD.

Main Results:

Complement proteins and activation products are present in AMD ocular tissues and circulation.
Genetic variations in complement pathway genes are associated with AMD.
Oxidative stress may trigger complement activation in AMD.

Conclusions:

The complement system plays a significant role in AMD pathogenesis.
Complement inhibitors show promise for preventing vision loss in AMD patients.
Further research into complement-targeted therapies is warranted.
