Autoimmune Disorders

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Skin Diseases and Disorders

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...

Gastritis-II: Pathophysiology

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Inflammatory Bowel Disease III: Crohn's Disease

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...

Type I Diabetes II: Pathophysiology

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...

Summary

Parasitic infections may protect against systemic lupus erythematosus (SLE), a multi-system autoimmune disease. This review explores the complex relationship between parasites, autoimmunity, and SLE development.

Area of Science:

Immunology
Autoimmunity
Infectious Disease

Background:

Systemic lupus erythematosus (SLE) is a complex autoimmune disease with genetic and environmental triggers.
The role of parasitic infections in the development or modulation of SLE remains unclear.
Understanding this association could reveal novel therapeutic strategies for autoimmune disorders.

Purpose of the Study:

To review current evidence linking parasitic infections to autoimmunity, specifically SLE.
To examine proposed mechanisms such as molecular mimicry and immune modulation by parasitic factors.
To discuss the correlation between parasitic load and the severity of autoimmune responses.

Main Methods:

Literature review of recent studies on parasites and autoimmunity.

Analysis of animal models investigating parasite-induced immune tolerance or autoimmunity.

Examination of molecular mimicry and immune-modulating properties of parasitic components.

Main Results:

Evidence suggests parasites can protect against autoimmunity, but also potentially trigger it.
Molecular mimicry between parasite and host antigens is a proposed mechanism for autoimmunity.
Parasitic molecules can significantly alter host immune responses, influencing autoimmune disease development.

Conclusions:

Parasitic infections present a complex interplay with autoimmune diseases like SLE.
Further research is needed to elucidate the precise mechanisms and therapeutic potential.
Targeting parasite-host interactions may offer new avenues for managing SLE.
