Insights

The complement system, crucial for immunity and inflammation, drives disease pathology in the central and peripheral nervous systems. Understanding its role aids diagnosis and treatment for neurological and psychiatric disorders.

Area of Science:

  • Immunology
  • Neuroscience
  • Pathology

Background:

  • The complement system is a key part of innate immunity and inflammation.
  • It plays a role in host defense but can also cause disease by driving inflammation and cell damage.
  • Complement is increasingly implicated in central nervous system (CNS) and peripheral nervous system (PNS) diseases, including infectious, autoimmune, degenerative, and neuropsychiatric disorders.

Purpose of the Study:

  • To review the evidence linking complement to CNS and PNS diseases.
  • To outline how this knowledge can improve diagnosis and patient outcomes.

Main Methods:

  • Literature review of studies implicating complement in neurological and psychiatric diseases.

Main Results:

  • The complement system is a significant factor in the pathogenesis of various CNS and PNS disorders.
  • Emerging complement-targeting drugs and biomarkers offer new therapeutic and diagnostic avenues.

Conclusions:

  • Complement's role in disease pathogenesis is increasingly recognized.
  • Targeting the complement system and utilizing complement analytes hold promise for diagnosing and treating neurological and psychiatric conditions.

Complement System01:27

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...

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Complementation Tests00:49

Complementation Tests

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...

Role of Neurotransmitters in Memory

Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
