Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.2K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Disorders of Erythrocytes

2.1K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Disorders of Leukocytes

1.8K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Bone Disorders01:29

Bone Disorders

5.1K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Panic Disorder01:27

Panic Disorder

651
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Area of Science:

  • Neuroimmunology
  • Immunology
  • Neurology

Background:

  • Neuroimmunological disorders involve immune system contributions to nervous system injury and repair.
  • Autoantibodies are crucial biomarkers for diagnosing and monitoring neuroimmunological diseases.
  • While autoantibody associations are known, their production mechanisms and roles require further investigation.

Purpose of the Study:

  • To discuss the roles of autoantibody-producing plasmablasts in neuroimmunological disorders.
  • To explore how comparing pathogenic and regulatory plasmablasts can elucidate disease mechanisms.
  • To highlight the potential for developing novel immune-modulatory therapies targeting plasmablasts.

Main Methods:

  • Review and discussion of existing evidence on plasmablasts in neuroimmunological diseases.
  • Comparative analysis of pathogenic versus regulatory plasmablast functions.
  • Exploration of potential therapeutic strategies based on plasmablast roles.

Main Results:

  • Autoantibodies are not uniformly pathogenic; some play regulatory roles.
  • Plasmablasts are implicated in both the pathogenicity and immune regulation of neuroimmunological diseases.
  • Understanding plasmablast heterogeneity is crucial for comprehending disease machinery.

Conclusions:

  • Elucidating plasmablast mechanisms in neuroimmunological disorders is essential for advancing diagnostics and therapeutics.
  • Targeting plasmablast function offers a promising avenue for new immune-modulatory treatments.
  • Further research into plasmablast roles may lead to improved management of neuroimmunological conditions.
