Summary: Atherosclerosis is characterized by persistent inflammation in the arterial wall, where trained immunity of the innate immune system may play a crucial role in its pathophysiology. This mechanism offers exciting novel pharmacological targets for the prevention or treatment of cardiovascular diseases.

Summary: Trained immunity is a long-term reprogramming of innate immune cells that is linked to atherosclerosis. This study investigated the link between type I interferons and trained immunity in patients with primary Sjogren's syndrome. The findings suggest that type I interferon induces a trained immunity phenotype in monocytes, while trained immunity also affects the production of type I interferons.

Summary: Aging and infection severity are closely related, with age as an independent predictor of mortality in sepsis. Trained immunity can improve immune function in aging and/or sepsis patients, but there is limited data on trained immunity in the aging immune system or in the presence of sepsis. This study found that trained immunity can be induced in aging monocytes and monocytes from sepsis patients, resulting in enhanced metabolic capacity and cytokine production.

Summary: Acute pancreatitis is a common gastrointestinal disease characterized by acute onset of abdominal pain, often leading to organ failure and death. Monocytes, a type of cells in the innate immune system, are highlighted as key contributors and regulators of the inflammatory response and organ failure in acute pancreatitis, with a special focus on lipid modulation.

Summary: Atherosclerosis is a leading cause of cardiovascular diseases and a major public health challenge. The mechanism of atherosclerosis is not fully understood, but alterations in lipid metabolism and inflammation play important roles. Recent research has shown significant effects of trained immunity on atherosclerotic plaque formation and development. Trained immunity is also a prominent factor in acute and chronic coronary syndrome.

Summary: Monocytes differentiate into macrophages at sites of inflammation and contribute to the development of cardiovascular disease. Different subtypes of monocytes, characterized by the expression of CD14 and CD16, have been identified. The middle subtype has been found to be associated with atherosclerosis, myocardial infarction, and heart failure. However, more research is needed to understand their exact role and predictive value in cardiovascular disease.

Summary: The use of electronic cigarettes (ECIGs) may increase vulnerability to future atherosclerotic cardiovascular disease due to changes in circulating factors. Monocyte transendothelial migration and monocyte-derived foam cell formation were higher in ECIG users and tobacco cigarette (TCIG) smokers compared to nonsmokers. However, these alterations were less severe in ECIG users compared to TCIG smokers.

Summary: Trained immunity is a non-specific enhanced responsiveness of innate immune cells that relies on epigenetic, transcriptional, and metabolic programs. It improves the response to infections and vaccines but may also contribute to the pathogenesis of cardiovascular, autoinflammatory, and neurodegenerative diseases.

Summary: Environmental microbial exposure has a profound impact on pulmonary immune memory, particularly on alveolar macrophages (AMs). AMs showed enhanced reactivity to pneumococcal challenge after intranasal exposure to ambient lipopolysaccharide (LPS). The training effect of AMs was found to be dependent on type 1 interferon signaling and inhibited by fatty acid oxidation and glutaminolysis. Moreover, adoptive transfer of trained AMs resulted in increased bacterial loads and tissue damage upon pneumococcal infection.

Summary: Macrophages play a central role in atherosclerosis pathogenesis, with their inflammatory activity regulated by the mTOR signaling pathway. Targeting mTOR and S6K1 pathways can reduce plaque inflammation, and Psap gene encoding prosaposin is closely related to mTOR signaling pathway, influencing glycolysis and oxidative phosphorylation. Prosaposin may serve as a potential therapeutic target for atherosclerosis.

Summary: Early childhood is characterized by repeated infectious exposures that elicit inflammatory responses from the innate immune system, which may contribute to the link between childhood infection and adult non-communicable diseases. Boys have a higher inflammatory response than girls, and adiposity and winter season are associated with increased circulating inflammatory markers.

Summary: Calcific aortic valve disease (CAVD) is the most common valvular disease in the developed world, but there is currently no effective pharmacological treatment available. Innate immune cells play a crucial role in the development of CAVD, similar to their role in atherosclerotic cardiovascular disease (ASCVD).

Summary: Antiphospholipid syndrome (APS) is an autoimmune disease characterized by the presence of antiphospholipid antibodies (aPL) that cause thrombotic and obstetric complications. APS serves as a model for studying the mechanisms of thromboinflammation and the relationship between innate immune cells and thrombosis. Monocytes are activated by aPL to produce proinflammatory cytokines and tissue factor, while neutrophils generate neutrophil extracellular traps and interact with endothelial cells, leading to thrombosis. Platelets become procoagulant upon activation by aPL and increase interactions with leukocytes. Understanding these mechanisms provides potential therapeutic targets for APS and other thromboinflammatory diseases.
