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.

Lower 24-Month Relative Survival among Black Patients with Non- Hodgkin’s Lymphoma: An Analysis of the SEER Data 1997-2015
Recent progress in the therapies used for patients with Non- Hodgkin’s lymphoma (NHL) has improved survival. In 2020, 77,240 people were diagnosed with NHL. Although it accounts for 4% of all cancers, the incidence has been reported to be decreasing in the last few years. About 26% of people will expire from NHL (15% males and 11% females).Non-Hodgkin lymphoma arises from the clonal expansion of B, T, and natural killer (NK) cells. There is a significant degree of heterogeneity in NHL and this is likely related to different degrees of differentiation and maturation of these cells. These hematological malignancies exhibit different tumor behavior and are responsive to different chemotherapy agents which impacts clinical outcomes. There are patients who can be cured with current regimens; however, subtypes such as indolent and some aggressive lymphomas remain incurable necessitating treatment with new therapies including immunotherapy, targeted therapy, CAR T cells, and hematopoietic stem cell transplant.

Are We Close to Achieving a HBV Cure? Risk for Hepatocellular Carcinoma Persists Despite Long-term HBV Suppression: An Update on Our Experience
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 Dual Role of Macrophages during Hepatitis B Infection
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.

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.
Chimeric Antigen Receptor CAR NK Cells Emerging Immunotherapy for the Treatment of Cancer
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.
Constitutively Active Death Receptor Induces Apoptosis in Mammalian Cells
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.
Karyotypic Profile of Chronic Myeloid Leukemia in Patients Diagnosed at Tertiary Level in Afghanistan
Balanced translocation resulting in fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2 is the pathognomonic molecular driver of CML. The resulting BCRABL 1 fusion gene is both the diagnostic as well as therapeutic target of CML. The first agent with tyrosine kinase inhibitor activity that was licenced in 2000 for treatment of CML patients, was Imatinib, gradually followed by multiple agents with higher efficacy.
