AI Article Synopsis

  • Platelets are involved in various key bodily functions like blood clotting, immune response, and even cancer development.
  • Platelet-derived extracellular vesicles (PDEVs) are gaining attention as important mediators and potential biomarkers due to their numerous roles in these processes.
  • The chapter discusses methods for isolating PDEVs from blood or activated platelets and clarifies that PDEVs refer to vesicles from both platelets and their precursor cells, megakaryocytes.

Article Abstract

Platelets participate in several physiological functions, including hemostasis, immunity, and development. Additionally, platelets play key roles in arterial thrombosis and cancer progression. Given this plethora of functions, there is a strong interest of the role of platelet-derived (extracellular) vesicles (PDEVs) as functional mediators and biomarkers. Moreover, the majority of the blood-borne EVs are thought to originate from either platelets or directly from the platelet precursor cells, the megakaryocytes, which reside in the bone marrow. To circumvent confusion, we use the term PDEVs for both platelet-derived and/or megakaryocyte-derived EVs. PDEVs can be isolated from blood or from isolated platelets after activation. In this chapter, we describe all commonly used PDEV isolation methods from blood and prepurified platelets.

Although therapies based on direct-acting antivirals (DAAs) effectively eradicate hepatitis C virus (HCV) in patients, there is still a high risk of liver fibrosis even after a sustained virological response. Therefore, it is of great clinical importance to understand the mechanism of potential factors that promote liver fibrosis after virological cure by treatment with DAAs. Here, we found that tubulointerstitial nephritis antigen-like 1 (TINAGL1) is significantly increased in HCV-infected hepatocytes and in the liver of patients with liver fibrosis, and that higher TINAGL1 expression persists in HCV-eradicated hepatocytes after treatment with DAAs.

: We aimed to assess the relationship among circulating extracellular vesicles (EVs), hypoxia-related proteins, and the conventional risk factors of life-threatening coronary artery disease (CAD) to find more precise novel biomarkers. : Patients were categorized based on coronary CT angiography. Patients with a Segment Involvement Score > 5 were identified as CAD patients.

Background: Chronic arterial hypertension restructures the vascular architecture of the brain, leading to a series of pathological responses that culminate in cerebral small-vessel disease. Pericytes respond dynamically to vascular challenges; however, how they manifest under the continuous strain of hypertension has not been elucidated.

Methods And Results: In this study, we characterized pericyte behavior alongside hypertensive states in the spontaneously hypertensive stroke-prone rat model, focusing on their phenotypic and metabolic transformation.

Over the last few decades, the primary cilium, an inconspicuous cell organelle, has increasingly become the focus of current research. The primary cilium is a microtubule-based, non-motile, antenna-like structure that is present on almost all mammalian cells. The ciliary membrane incorporates a large number of receptor molecules, which further characterize this cellular organelle.
