Abstract

Insights

Familial Mediterranean Fever (FMF) patients exhibit endotoxin tolerance and altered monocyte apoptosis during attacks, suggesting inflammation resolution. Remission periods show proinflammatory responses and apoptosis resistance.

Area of Science:

  • Immunology
  • Genetics
  • Inflammation

Background:

  • Familial Mediterranean Fever (FMF) is an autoinflammatory disorder.
  • Understanding immune dysregulation in FMF is crucial for treatment.

Purpose of the Study:

  • To investigate endotoxin tolerance, cytokine polarization, and monocyte apoptosis in FMF patients.
  • To differentiate immune responses during FMF attacks versus remission.

Main Methods:

  • Lipopolysaccharide (LPS)-induced tolerance, cytokine synthesis, and monocyte apoptosis were analyzed.
  • Flow cytometry and whole blood cell culture techniques were employed.

Main Results:

  • FMF patients in attack developed endotoxin tolerance and enhanced monocyte apoptosis.
  • During remission, monocytes showed proinflammatory polarization and apoptosis resistance.
  • Colchicine treatment modulated cytokine synthesis and reduced monocyte apoptosis.

Conclusions:

  • FMF attacks may involve inflammation resolution mechanisms.
  • Immune responses in FMF differ significantly between attack and remission phases.
  • These findings offer insights into FMF pathogenesis and colchicine's effects.

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Myasthenia Gravis ll: Pathophysiology

The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Acute Inflammation I: Inflammatory Response01:26

Acute Inflammation I: Inflammatory Response

Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
