Assessment of the Antigen-Binding Capacity and Separation of Extracellular Vesicles Coated with Antigen-Specific Antibody Light Chains.

Many researchers are interested in the possibility of manipulating the targeting specificity of extracellular vesicles (EVs) for their use as physiological delivery vehicles for drugs and bioactive molecules. Our studies demonstrated the possibility of directing EVs toward the desired acceptor cell by coating them with antigen-specific antibody light chains. Here, we describe the methods for detection of the presence of antibody light chains on the EV surface, proving their ability to specifically bind the antigen and for separating the antigen-binding EV subpopulation.

Role of Lipid-Lowering and Anti-Inflammatory Therapies on Plaque Stabilization.

Atherosclerosis is the predominant underlying etiopathology of coronary artery disease. Changes in plaque phenotype from stable to high risk may spur future major adverse cardiac events (MACE). Different pharmacological therapies have been implemented to mitigate this risk.

Macrophage Functions in Psoriasis: Lessons from Mouse Models.

Psoriasis is a systemic autoimmune/autoinflammatory disease that can be well studied in established mouse models. Skin-resident macrophages are classified into epidermal Langerhans cells and dermal macrophages and are involved in innate immunity, orchestration of adaptive immunity, and maintenance of tissue homeostasis due to their ability to constantly shift their phenotype and adapt to the current microenvironment. Consequently, both macrophage populations play dual roles in psoriasis.

Hypotensive drugs mitigate the high-sodium diet-induced pro-inflammatory activation of mouse macrophages in vivo.

Nowadays, there is an increasing emphasis on the need to alleviate the chronic inflammatory response to effectively treat hypertension. However, there are still gaps in our understanding on how to achieve this. Therefore, research on interaction of antihypertensive drugs with the immune system is extremely interesting, since their therapeutic effect could partly result from amelioration of hypertension-related inflammation, in which macrophages seem to play a pivotal role.

Sex-specific associations between the environmental exposures and low-grade inflammation and increased blood pressure in young, healthy subjects.

Long-term exposures to environmental factors including airborne as well as noise pollutants, are associated with cardiovascular risk. However, the influence of environmental pollution on the young population is controversial. Accordingly, we aimed to investigate the relationships between long-term exposures to different environmental factors and major cardiovascular and inflammatory parameters and biomarkers in young, healthy subjects.
