Editorial Note

Immune dysregulation is the proposed or confirmed breakdown or maladaptive change in molecular control of immune system processes. Dysregulation is a factor in the development of autoimmune disorders and some malignancies. IPEX (Immune dysregulation, polyendocrinopathy, enteropathy, X-linked disease) is a syndrome caused by a mutation in the FOXP3 gene, which codes for a regulatory T cell transcription factor (Tregs). As a result of this mutation Tregs become dysfunctional, resulting in autoimmune disorders. Enteropathy, type I diabetes, persistent diarrhoea, failure to thrive, dermatitis, and haemolytic anaemia and eczema are the most common clinical symptoms. Other people with IPEX syndrome are more likely to have autoimmune illnesses or hypersensitivity. Individuals with autoimmune illnesses have higher immunological reactivity and are more susceptible to infections. A lot of people have autoimmune disorders when they're young. A mutation in CTLA-4 could be the cause of further T cell-associated immunological dysregulation. Hypogammaglobulinemia, frequent infections, and the occurrence of autoimmune illnesses are all symptoms of the disease. Individuals may experience the condition in different ways, with some experiencing only a partial drop in Tregs, while others have a reduction in their ability to bind CTLA-4 ligand, causing effector T and B cell homeostasis to be disrupted. This syndrome has an autosomal dominant inheritance pattern with partial penetration.

Chronic stress can cause chronic inflammation and immunological dysregulation at various stages of life. People who had severe stress as a child (abuse, neglect, etc.) are more likely to develop cardiovascular disease, type 2 diabetes, osteoporosis, rheumatoid arthritis, and other immune-related issues later in life. Individuals who experienced more stress as children are more likely to develop chronic inflammation later in life. Individuals that are stressed have higher levels of IL-6. Chronic stress enhances the development of pro inflammatory monocytes and macrophages in children, as well as resistance to antiinflammatory agents. Individuals who have been exposed to a lot of stress have greater antibody titers to viruses including Herpes simplex virus, Epstein–Barr virus, and Cytomegalovirus than people who haven't been exposed to a lot of stress.

Immune dysregulation can also be triggered by toxins. In environmental workers, greater exposure to pesticides (such as DDT, organophosphate, amides, etc.) alters immune system responses. The severity of the damage is determined by the individual's age, dose, and duration of toxin exposure. Even with a little dose of toxins, there are considerable detrimental impacts in children and adolescents. The ability to break down harmful compounds and the ensuing influence on the organism, on the other hand, is linked to the individual's metabolism and genetic makeup. Toxins can operate directly on the cellular component of immunity, through their metabolites, or they can enhance reactive oxygen species (ROS) in the body, through antioxidant depletion, or through oxidative stress. Traditional environmental toxins and irritants, such as saliva enzymes of blood-feeding parasites, insect poisons, and plant irritants, can also trigger allergic reactions. These compounds have the ability to break cell membranes, activate cell receptors, agglomerate or degrade proteins, and damage the mucosal surface layer. The immune system frequently reacts to these compounds by causing itching, coughing, sneezing, or vomiting, which all result in the removal of the irritant substance from the body. Combining the impacts of numerous poisons at the same time can exacerbate the harmful consequences, but the effects of the toxins can also cancel each other out in some situations.
