Objective: To systematize data on the role of monocytes in the pathogenesis of multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE).
Material And Methods: Forty-six scientific publications (1990-2024) on the role of monocytes in the pathogenesis of EAE and MS were analyzed.
Results: Monocytes have been found to play an essential role in both the occurrence and persistence of autoimmune neuroinflammation. They penetrate the central nervous system (CNS) through the blood-brain barrier, produce pro-inflammatory cytokines, differentiate into macrophages/dendritic cells, and activate CD4 T-cells. The change in both quantitative and functional characteristics of monocytes in MS is described.
Conclusion: Monocytes are involved in all stages of the immunopathogenesis of EAE and MS and largely mediate autoimmune demyelination in the CNS. Therefore, they can be considered a potential therapeutic target for MS.

Background: Cryopyrin-associated periodic syndrome (CAPS) is an autoinflammatory disease caused by a gain-of-function mutation in the gene, which regulates inflammasome-mediated interleukin-1β (IL-1β) production. This leads to recurrent episodes of fever, rash, and arthritis, typically beginning in childhood.
Objective: To demonstrate the role of a missense mutation, c.

Myocarditis is a life-threatening inflammatory disorder that affects the cardiac muscle tissue. Current treatments merely regulate heart function but fail to tackle the root cause of inflammation. In myocarditis, the initial wave of inflammation is characterized by the presence of neutrophils.

Exposure to nanoplastics (NPs), a pervasive environmental pollutant, presents potential health risks. Pulmonary exposure to NPs has been shown to disrupt both pulmonary metabolic status and immune homeostasis, leading to concerns about their impact on respiratory health and systemic well-being. However, the underlying linkage and mechanisms remain elusive.

The sensing of Gram-negative Extracellular Vesicles (EVs) by the innate immune system has been extensively studied in the past decade. In contrast, recognition of Gram-positive EVs by innate immune cells remains poorly understood. Comparative genome-wide transcriptional analysis in human monocytes uncovered that S.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.
