[Granulocyte disease caused by glycoprotein complex deficiency correlated with leukocyte adhesion]

Insights

Patients with a genetic deficiency in CR3, LFA-1, and p150,95 leukocyte antigens exhibit increased bacterial infections due to neutrophil functional abnormalities.

Area of Science:

  • Immunology
  • Genetics
  • Cell Biology

Context:

  • Focuses on leukocyte adhesion molecule deficiencies.
  • Reviews clinical and laboratory findings in affected families.
  • Highlights the role of CR3, LFA-1, and p150,95 antigens.

Purpose:

  • To summarize clinical and laboratory findings of patients with genetic deficiencies in CR3, LFA-1, and p150,95.
  • To review the neutrophil functional abnormalities in these patients.
  • To correlate these deficiencies with increased susceptibility to bacterial infections.

Summary:

  • Describes an autosomal recessive disease affecting leukocyte membrane surface antigens (CR3, LFA-1, p150,95).
  • Each antigen comprises a common beta-chain and distinct alpha-chains.
  • Patients present with neutrophil functional deficiencies, impacting phagocytosis and cytotoxicity.
  • This leads to increased susceptibility to bacterial infections, similar to other neutrophil disorders.

Impact:

  • Enhances understanding of leukocyte adhesion molecule function in immunity.
  • Provides insights into neutrophil dysfunction and its clinical consequences.
  • Contributes to the diagnosis and management of primary immunodeficiencies.

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
Proteoglycans01:05

Proteoglycans

Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
Classification of Leukocytes01:30

Classification of Leukocytes

Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...
Disorders of Leukocytes01:27

Disorders of Leukocytes

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 system...
Hypersensitivity Reactions: Cytolytic Reactions01:01

Hypersensitivity Reactions: Cytolytic Reactions

Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
