Autoimmune Disorders01:29

Autoimmune Disorders

2.1K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Chemical Synapses01:26

Chemical Synapses

12.4K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Myasthenia Gravis: Overview and Treatment

3.4K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Disorders of the Nervous Tissue

3.0K
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.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

  • Neurology
  • Synaptic Biology

Background:

  • Autoantibodies targeting neuromuscular junction proteins cause myasthenic syndromes.
  • Autoantibodies against central nervous system (CNS) proteins are increasingly recognized in severe neurological and psychiatric disorders.
  • Synaptic dysfunction is a key mechanism in autoimmune neurological diseases.

  • To review clinical and experimental evidence linking autoantibodies to autoimmune disorders of the CNS and neuromuscular junction.
  • To elucidate the role of autoantibodies in disrupting synaptic integrity.
  • To explore the potential of studying autoimmune CNS disorders for broader insights into CNS mechanisms.

Main Methods:

  • Review of clinical case studies and patient data.
  • Analysis of in vitro experimental models of autoimmune neurological diseases.
  • Examination of in vivo animal models investigating autoimmune synaptic disruption.

Main Results:

  • Substantial evidence supports autoantibodies as causative agents in myasthenic syndromes.
  • Growing evidence implicates autoantibodies in severe, treatable CNS disorders.
  • Autoantibodies disrupt synaptic function and structure, leading to neurological deficits.

Conclusions:

  • Autoantibodies are critical players in autoimmune neurological and neuromuscular disorders.
  • Understanding autoimmune CNS diseases offers a unique window into fundamental CNS cellular and circuit mechanisms.
