Introduction: Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system (CNS) characterized by T-cell-mediated autoinflammation and demyelination of neurons with its typical presentation in young adulthood. Adverse childhood experiences (ACEs) are proposed to increase the risk of developing multiple sclerosis (MS) later...

Inflammatory and autoimmune disorders, characterized by dysregulated immune responses leading to tissue damage and chronic inflammation, present significant health challenges. This review uniquely focuses on efferocytosis—the phagocyte-mediated clearance of apoptotic cells—and its pivotal role in these disorders. We delve into the intricate mechani...
The proposed paper is devoted to presenting and analyzing a kinetic model describing the development of autoimmune disorders. The proposed model is a nonlinear system of differential equations that considers the biological activity of the interacting populations. The main characteristics of autoimmune diseases are taken into account. Preliminaries...
Background
Autologous hemopoietic stem cell transplantation (AHSCT), is an extensive procedure that allows for the depletion of the immune system and its restoration from hemopoietic stem cells. The approach has been modified for the treatment of severe immune-mediated illnesses including multiple sclerosis, after being initially devised for the tr...
Hepatitis, a medical condition distinguished by inflammation of the liver, may arise from various etiological factors, including viral infections, chemical exposure, autoimmune disorders, or other specific viral pathogens. For over two decades, diabetes mellitus has been associated with chronic liver diseases, including hepatitis B (HBV) and hepati...
OBJECTIVE: The main objective of performing this study was the mutational analysis of Forkhead box family member (FoxP3) and Interleukin-22 (IL-22) genes and their associations with systemic lupus erythematosus (SLE). MATERIALS AND METHODS: A total of sixty blood samples were collected from SLE patients from different hospitals in Lahore. Profor-ma...

... Both epidemiological and experimental studies have found an association between adverse childhood experiences (ACEs) and MS [19][20][21][22][23]. ACEs represent potentially traumatic events, such as abuse or neglect, witnessing violence, or growing up in a household with drug use, mental health problems, or instability due to parental separation, death, or incarceration. ...
... Two systematic reviews have summarized the evidence from observational studies investigating the association between ACEs and MS [19,21]. The systematic reviews investigated MS onset and other clinical features of MS in association with ACEs. ...
... Both reviews concluded that the evidence supports a link between childhood stress and MS risk. They also reported that people with a history of ACEs develop MS symptoms at a younger age, that they have more fatigue and exaggerated reaction to pain, and that ACE severity is associated with an increased rate of MS relapses [19,21]. ...
Adverse childhood experiences (ACEs), such as abuse, neglect, and household dysfunction, contribute to long-term systemic toxic stress and inflammation that may last well into adulthood. Such early-life stressors have been associated with increased susceptibility to multiple sclerosis (MS) in observational studies and with the development of experimental autoimmune encephalomyelitis in animal models. In this review, we summarize the evidence for an ACE-mediated increase in MS risk, as well as the potential mechanisms for this association. ACEs dysregulate neurodevelopment, stress responses, and immune reactivity; they also alter the interplay between the immune system and neural networks. All of this may be relevant for MS risk. We further discuss how ACEs induce epigenetic changes and how the toxic stress caused by ACEs may reactivate the Epstein-Barr Virus (EBV), a key risk factor for MS. We conclude by suggesting new initiatives to obtain further insights into this topic.
