Chemotherapy Promotes Release of Exosomes Which Upregulate Cholesterol Synthesis and Chemoresistance in AML Blasts
Extracellular vesicles (EVs) are emerging as a key mediator of intercellular communication as well as a major mechanism of functional reprogramming of cells in disease. All cells produce EVs, which freely circulate and are found in all body fluids. EVs are heterogenous, consisting of subsets of vesicles with different sizes, distinct origins, and various functions (Figure 1). They mediate a broad variety of biological events ranging from cellular activation, inflammation, blood coagulation, angiogenesis, cellular transport, and others. Among these vesicles, a subset of small EVs (30-150 nm in diameter) originating from multivesicular bodies (MVBs) in parent cells and referred to as small extracellular vesicles (sEVs) carry proteomic, genomic and functional signatures that resemble those of parent cells and are, therefore, taken as surrogates of parent cells. In cancer, tumor-derived exosomes (TEX) reflect characteristics of tumor cells and are considered candidates for “liquid tumor biopsy”. Emerging evidence shows that TEX are a major sEV subset in plasma of patients with cancer, including hematologic malignancies.

Since the discovery of the hepatitis B virus (HBV) by Blumberg et al., great progress has been made in understanding the pathogenesis of the virus and its role in hepatocellular carcinoma (HCC). It is estimated that hepatitis B is responsible for about 50% of the HCC cases worldwide. Because of geographic variations in HBV incidence, the burden of HBV-related HCC (HBV-HCC) is highest in endemic areas such as Asian-Pacific and sub- Saharan Africa and lowest in the United States and the West. The hepatitis B vaccines, developed in the 1980s, transformed the evolution of hepatitis B in the modern era. This was followed by high effective anti-viral that reduced HBV infections and HBV-HCC.
The exchange of information within the cell is extremely complex. Besides the well-studied chemical signalling, physical signalling is required to fulfil spatial and temporal aspects. The Golgi apparatus and the microtubule skeleton system are the decisive structures for numerous intracellular transport tasks.
The main symptom in Chronic Obstructive Pulmonary Disease (COPD) is shortness of breath. Shortness of breath occurs especially with exercise and progresses over the years despite all medical treatments. One of the main mechanisms by which this symptom occurs is hyperinflation in the lungs .
Hepatitis B virus (HBV) chronically infects more than 250 million individuals worldwide and is responsible for more than 800,000 deaths per year by promoting end-stage liver diseases, among which decompensated cirrhosis and hepatocellular carcinoma (HCC) (WHO, July 2020) are prominent. Studies performed in chimpanzees or in animalversion of HBV (woodchuck HBV: WHBV) highlighted the lack of immune responses against the virus upon primary infection. Thus, HBV has been described as a “stealth” virus (i.e. a virus that does not modify/induce immune response in the cell). However, a growing number of studies describe that HBV is able to rapidly and efficiently counteract the innate immune response in a large variety of cells (hepatocytes, macrophages, Natural Killer cell…). Hereby, we focus on the role of macrophages (Mφ) during HBV infection.
In this paper we consider the hypothesis, based on our human and mouse studies, that white matter connectivity can be altered by appropriate stimulation at the theta frequency [1,2]. In one study we used optogenetics to change the output of cells in the mouse anterior cingulate cortex (ACC) at 1, 8 or 40Hz.
In the last decade, the study of nanometer-scale particles has grown exponentially worldwide. This growth is due to the broad field of nanostructures applications, which, due to their dimensions in nanometric sizes, have new properties not found in micro and macro scale. These properties result from the increase in the ratio between the surface area and volume, and the nanostructures’ size directly influences these. Tolerance to temperature, variety of colors, changes in chemical reactivity,

Gastric cancer (GC), also known as stomach cancer, is a worldwide health problem. Anatomically, it can occur from the gastroesophageal junction to distal portions of the stomach. Considering both sexes, worldwide, it is the 5th most common neoplasm (5.7%) and the 3rd cause of mortality among malignancies, leading to approximately 782,000 deaths in 2018. The incidence varies geographically but 50% of new cases are diagnosed in developed countries. High incidence is observed in Asia, Latin America, and in the central and eastern parts of Europe. There are several ways to classify GC, but the most used is Lauren’s Classification, which proposes two main histological groups: intestinal and diffuse. This classification is important because there are marked etiological, pathological, and epidemiological differences between the subgroups, guiding the clinical approach for each patient.
Various types of forces, such as cohesive and adhesive forces, are involved in physical and biological processes.

It is now well accepted that the ionizing radiation-generated reactive oxygen species (ROS), that constitute ~2/3 of the effects of external beam radiation, do not only produce direct tumor cell death, but also affect the surrounding microenvironment. Moreover, this indirect effect of radiation may result in systemic effects, specifically the initiation of an inflammatory response.
Although NK cells are recognized as effector lymphocytes of the innate immune system, they also regulate the adaptive immune response by releasing inflammatory cytokines and developing immunological memory. Unlike other lymphocytes such as T or B cells, NK cells do not express rearrangeable, antigen-specific receptors.
Apoptosis is a physiological response in development and homeostasis of metazoans. Apoptosis is triggered during pathological events as a means to renew affected tissues and eliminate cancer cells. The immune system regulates the extrinsic pathway of apoptosis, where signals such as TNFα or displayed ligands on the surface of immune cells trigger signal cascades by death receptors present on targeted cells.
