Summary
Complement C3 plays a key role in psoriasis pathogenesis. Targeting complement C3 offers a promising therapeutic strategy for managing this chronic inflammatory skin disease.
Area of Science:
- Immunology
- Dermatology
- Biochemistry
Background:
- Psoriasis is a chronic inflammatory skin disease with complex immune system involvement.
- The complement system, a crucial part of innate immunity, is implicated in inflammatory processes.
- Complement C3 is a central molecule in complement system activation and has been linked to psoriasis.
Purpose of the Study:
- To explore the pathogenic mechanisms of complement C3 in psoriasis.
- To evaluate complement C3 as a potential therapeutic target for psoriasis.
- To review current therapeutic strategies targeting complement C3.
Main Methods:
- Literature review of studies on complement system, C3, and psoriasis.
- Analysis of C3 structure, function, and biological roles in immune response.
- Examination of C3 convertase formation and its cleavage products (C3a, C3b).
- Investigation of C3 expression and function in T cells (CD4+).
Main Results:
- Complement C3 contributes to immune abnormalities and skin lesions in psoriasis.
- C3 activation leads to the formation of C3a and C3b, influencing T cell differentiation and survival.
- Studies show C3a receptor (C3aR) inhibitors, like SB290157, can slow psoriasis progression.
Conclusions:
- Complement C3 is a significant pathogenic factor in psoriasis.
- Targeting complement C3 presents a novel and effective therapeutic avenue for psoriasis treatment.
- Further research into C3-targeted therapies could advance clinical interventions for psoriasis.

01:19Hypersensitivity Reactions: Immune-Complex Reactions
127
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...

01:19Formation of Lipopolysaccharides

Lipopolysaccharides (LPS) are crucial components of the outer membrane of Gram-negative bacteria, serving both structural and functional roles. It contributes to membrane stability and protects bacteria from host immune responses. LPS is composed of three major regions—lipid A, a core oligosaccharide, and an O antigen. The biosynthesis and assembly of LPS involve a highly coordinated set of enzymatic reactions and transport mechanisms. Additionally, LPS is recognized as an endotoxin,...

01:27Complement System
12.2K
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...

01:24T Cell Types and Functions
3.2K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.

A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...
