Hypersensitivity Reactions: Cytolytic Reactions

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...

Hypersensitivity Reactions: Immune-Complex Reactions

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...

Transcytosis of IgG

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Jaundice

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Summary

Cryoglobulins, proteins that solidify in cold, are linked to hepatitis C and autoimmune diseases. This review covers cryoglobulinemia types, symptoms, and treatments for this immune complex disorder.

Area of Science:

Immunology
Rheumatology
Virology

Context:

Cryoglobulins are immunoglobulins precipitating below 37°C.
Often associated with Hepatitis C virus (HCV) infection.
Can occur in autoimmune and hematologic conditions.

Purpose:

To review cryoglobulinemia types.
To describe clinical presentations.
To discuss current therapeutic strategies.

Summary:

Cryoglobulins form immune complexes causing tissue damage in skin, joints, and kidneys.
This review details cryoglobulinemia classification and clinical manifestations.
It also outlines contemporary treatment approaches for managing cryoglobulinemia.
