Summary
The complement system, a key host defense, generates C5a, a potent inflammatory molecule. This review details C5a
Area of Science:
- Immunology
- Host Defense Mechanisms
- Molecular Biology
Background:
- The complement system is an ancient, highly regulated host defense mechanism.
- It bridges innate and adaptive immunity, involving ~50 glycoproteins.
- Complement activation produces anaphylatoxins like C5a, a potent pro-inflammatory mediator.
Purpose of the Study:
- To provide a comprehensive overview of human C5a.
- To discuss C5a's structure and signaling in various pathophysiological conditions.
- To explore current and future therapeutic strategies targeting C5a.
Main Methods:
- Literature review of complement system and C5a research.
- Analysis of C5a's role in inflammation and disease.
- Examination of therapeutic interventions targeting C5a.
Main Results:
- C5a is a critical anaphylatoxin involved in widespread inflammatory signaling.
- Its structure and signaling pathways are complex and context-dependent.
- C5a plays significant roles in numerous pathophysiological conditions.
Conclusions:
- Understanding C5a's multifaceted roles is crucial for developing targeted therapies.
- Therapeutic strategies aimed at inhibiting C5a show promise for various inflammatory diseases.
- Further research into C5a modulation could lead to novel treatments.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:27Complement System
2.5K
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...

48.3K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.

2.4K
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.

3.4K
A signaling cascade is a series of events that facilitates the transmission of information within or between cells, culminating in a targeted response in the recipient cell. As chemical messengers, hormones are pivotal in initiating and modulating these intricate signaling cascades based on their solubility.

3.4K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...
