Summary
Pemphigoid gestationis is a rare pregnancy dermatosis caused by auto-antibodies targeting BP Antigen 2. While it can cause preterm birth, neonates are rarely affected, and corticosteroids are the primary treatment.
Area of Science:
- Immunodermatology
- Obstetrics
- Autoimmune diseases
Background:
- Pemphigoid gestationis (PG) is a rare, specific subepidermal blistering disease that occurs during pregnancy.
- It is characterized by an autoimmune response involving IgG1 auto-antibodies.
- These antibodies target the 180 kD BP Antigen 2, a component of the dermal-epidermal junction.
Observation:
- PG presents as a blistering skin condition during gestation.
- The condition is associated with potential complications for the pregnancy, including preterm delivery.
- Neonatal involvement is infrequent, occurring in approximately 10% of cases.
Findings:
- The pathogenesis of PG involves IgG1 auto-antibodies binding to 180 kD BP Antigen 2.
- The primary clinical concern is the risk of preterm delivery.
- Neonatal outcomes are generally favorable, with low rates of fetal or neonatal complications.
Implications:
- Early diagnosis and management of PG are crucial for maternal and fetal well-being.
- Systemic corticosteroids are the established first-line treatment for pemphigoid gestationis.
- Understanding the autoimmune mechanism aids in developing targeted therapies for pregnancy-related dermatoses.

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

3.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:15Transcytosis of IgG
3.8K
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...

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
