Summary
Urticaria in horses involves complex immune responses, with mast cells releasing mediators. Identifying the cause is key for treatment, though often challenging.
Area of Science:
- Veterinary Dermatology
- Equine Medicine
- Immunology
Background:
- Urticarial eruptions are common in horses, with potential immunological and other pathogenetic mechanisms.
- Mast cells, coordinating urticarial responses through inflammatory mediators, are implicated, alongside neutrophils, eosinophils, and macrophages.
- The precise roles of various cells and mediators in equine urticaria are still under investigation.
Purpose of the Study:
- To review potential factors contributing to urticaria in horses.
- To outline a standard diagnostic approach for identifying the underlying cause of equine urticaria.
Main Methods:
- Literature review of immunological and cellular mechanisms in urticaria.
- Discussion of diagnostic strategies for equine dermatological disorders.
- Synthesis of current understanding of urticaria pathogenesis in horses.
Main Results:
- Equine urticaria involves complex cellular and mediator interactions, similar to human responses.
- Identifying the specific cause of urticaria in horses can be diagnostically challenging.
- A systematic diagnostic approach is crucial for effective management.
Conclusions:
- Understanding the cellular and mediator roles in equine urticaria is an evolving field.
- Effective treatment necessitates identifying the underlying cause, despite diagnostic difficulties.
- This review provides a framework for diagnosing and managing equine urticaria.

Epistasis
48.1K
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Skin Diseases and Disorders

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...

Accessory Structures of the Skin: Hair and Hair Follicles
3.2K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Hypersensitivities
1.5K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Gastritis III: Clinical Manifestations and Management
598
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
