PURPOSE OF REVIEW: Over the last century, the diseases associated with macrocytic anemia have been changing with more patients currently having hematological diseases including malignancies and myelodysplastic syndrome. The intracellular mechanisms underlying the development of anemia with macrocytosis can help in understanding normal erythropoiesis. Adaptations to these diseases involving erythroid progenitor and precursor cells lead to production of fewer but larger red blood cells, and understanding these mechanisms can provide information for possible treatments...

PURPOSE OF REVIEW: Platelets are essential for hemostasis and are also vital in lymphatic and lung development and the maintenance of vascular integrity. Platelet activation receptor C-type lectin-like receptor 2 (CLEC-2) and its endogenous ligand podoplanin (PDPN) in lymphatic endothelial cells (LECs) and other cells regulate these processes. This review aims to comprehensively summarize the roles of platelet CLEC-2 and PDPN. This review also focuses on discussing the underlying mechanisms by which platelet CLEC-2 and PDPN mediate blood/lymphatic separation...

PURPOSE OF REVIEW: Thrombo-inflammation is a multifaceted pathologic process involving various cells such as platelets, neutrophils, and monocytes. In recent years, microRNAs have been consistently implicated as regulators of these cells. RECENT FINDINGS: MicroRNAs play a regulatory role in several platelet receptors that have recently been identified as contributing to thrombo-inflammation and neutrophil extracellular trap (NET) formation. In addition, a growing body of evidence has shown that several intracellular and extracellular microRNAs directly promote NET formation...

Tal Bacharach, Nathali Kaushansky, Liran I Shlush
PURPOSE OF REVIEW: Both aging and reduced diversity at the hematopoietic stem cells (HSCs) level are ubiquitous. What remains unclear is why some individuals develop clonal hematopoiesis (CH), and why does CH due to specific mutations occur in specific individuals. Much like aging, reduced diversity of HSCs is a complex phenotype shaped by numerous factors (germline & environment). The purpose of the current review is to discuss the role of two other age-related ubiquitous processes that might contribute to the dynamics and characteristics of losing HSC diversity and the evolution of CH...

PURPOSE OF REVIEW: We provide an update on the successes and ongoing challenges of Menin inhibition as a novel approach for the treatment of patients with acute leukemias that express HOXA cluster genes including leukemias with KMT2A-rearrangements, NPM1 mutations or NUP98-rearrangements. Initial clinical trials show promising response rates in heavily pretreated patients suggesting these inhibitors may have a significant impact on patient outcome. Furthermore, the development of resistance mutations that decrease drug binding affinity, validates Menin as a therapeutic target in human cancers...

PURPOSE OF REVIEW: The platelet surface harbors a lush forest of glycans (carbohydrate polymers) attached to membrane proteins and lipids. Accumulating evidence suggests that these glycans may be relevant to the pathophysiology of immune thrombocytopenia (ITP). Here, we critically evaluate data that point to a possible role for loss of sialic acid in driving platelet clearance in ITP, comment on the potential use of neuraminidase inhibitors for treatment of ITP, and highlight open questions in this area...

PURPOSE OF REVIEW: This review summarizes the pathophysiology and potential therapeutic options for treatment of multiple sclerosis, a common neuronal demyelinating disorder affecting 2.2 million people worldwide. As an autoimmune disorder, multiple sclerosis is associated with neuroinflammation and increased permeability of the blood-brain barrier (BBB), although the cause linking multiple sclerosis with compromised barrier function remains ill-defined. It has been previously shown that coagulation factors, including thrombin and fibrin, exacerbate the inflammatory processes and permeability of the BBB...

Sickle cell disease is a debilitating hemoglobinopathy with high morbidity and mortality. Hematopoietic stem cell transplantation (HCT) is curative, but the presence of mixed donor/recipient chimerism post-HCT raises concerns about disease control long-term. Mixed donor/recipient chimerism is reported in significant numbers even after aggressive HCT conditioning regimens. Post-HCT, adequacy of donor erythropoiesis is crucial for disease control. This review explores the relationship between mixed donor/recipient chimerism and outcomes post-HCT...

PURPOSE OF REVIEW: Cancer-associated thrombosis (CAT), such as venous thromboembolism (VTE), is a frequent complication in cancer patients, resulting in poor prognosis. Breast cancer is not highly thrombogenic but is highly prevalent, resulting in increased VTE cases. Many cancers express tissue factor (TF), a glycoprotein that triggers coagulation. The cancer cells were shown to express and release substantial amounts of TF-positive microparticles (MPTF), associated with a prothrombotic state...

PURPOSE OF REVIEW: We present a case of a boy diagnosed in 2007 with severe haemophilia B [factor IX (FIX) concentration < 1%] at age of 9 months. He was initially treated with recombinant FIX concentrates, but changes in regimens were frequent due to spontaneous hemarthros. In 2013, he entered a phase III trial (NCT01662531) and received rIX-FP, IDELVION at 50 IU/kg once a week. Although the boy was safely maintained with this regimen (2015-2017), the number of hemarthros increased after he started to play football...
