Engagement of Mesenchymal Stromal Cells in the Remodeling of the Bone Marrow Microenvironment in Hematological Cancers.

Mesenchymal stromal cells (MSCs) are a subset of heterogeneous, non-hematopoietic fibroblast-like cells which play important roles in tissue repair, inflammation, and immune modulation. MSCs residing in the bone marrow microenvironment (BMME) functionally interact with hematopoietic stem progenitor cells regulating hematopoiesis. However, MSCs have also emerged in recent years as key regulators of the tumor microenvironment. Indeed, they are now considered active players in the pathophysiology of hematologic malignancies rather than passive bystanders in the hematopoietic microenvironment. Onc

Molecular-Based Treatment Strategies for Osteoporosis: A Literature Review.

Osteoporosis is an unavoidable public health problem in an aging or aged society. Anti-resorptive agents (calcitonin, estrogen, and selective estrogen-receptor modulators, bisphosphonates, anti-receptor activator of nuclear factor κB ligand antibody along with calcium and vitamin D supplementations) and anabolic agents (parathyroid hormone and related peptide analogs, sclerostin inhibitors) have major roles in current treatment regimens and are used alone or in combination based on the pathological condition. Recent advancements in the molecular understanding of bone metabolism and in bioengin

Лекция Barancik Award: Многодисциплинарные исследования будут ключом к остановке, восстановлению и окончанию MS.

За последние 25 лет мы добились небывалых успехов в понимании патогенеза MS и последующем развитии эффективных методов лечения. Совместные усилия в области генетики позволили выявить связь 236 общих вариантов ДНК с подверженностью болезням и первую связь с серьезностью заболеваний, что проложило путь к более эффективной терапии, особенно для прогрессивных форм заболевания. Параллельно и в дополнение к уже существующим экологическим заболеваниям, вызывающим или изменяющим себя, новая совместная работа выявила новые связи с компонентами кишечного микробиома. Это исследование открыло новую и захв

Multiple myeloma cancer stem cells.

Multiple myeloma (MM) remains incurable despite much progress that has been made in the treatment of the disease. MM cancer stem cell (MMSC), a rare subpopulation of MM cells with the capacity for self-renewal and drug resistance, is considered to lead to disease relapse. Several markers such as side population (SP) and ALDH1+ have been used to identify MMSCs. However, ideally and more precisely, the identification of the MMSCs should rely on MMSCs phenotype. Unfortunately the MMSC phenotype has not been properly defined yet. Drug resistance is the most important property of MMSCs and contribu

Obesity and Cancer: Mechanisms, Epidemiological Evidence, and Potential Risk Reduction.

Obesity promotes carcinogenesis through interlocking metabolic, inflammatory, immune, and hormonal pathways. We narratively synthesize recent meta-analyses and selected cohort studies that examine adiposity-principally body mass index (BMI) and waist circumference-in relation to cancer incidence. Across the 13 cancers designated by the U.S. National Cancer Institute as obesity-associated, risk elevations are generally consistent, though magnitudes vary by histology (e.g., esophageal adenocarcinoma vs. squamous cell carcinoma), anatomic subsite (gastric cardia vs. non-cardia), sex or menopausal

Efficacy and Safety of Lenalidomide Monotherapy for Relapsed/Refractory Diffuse Large B Cell Lymphoma: Systematic Review and Meta-Analysis.

IntroductionSeveral maintenance therapies are available for treatment of patients with relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). The objective of this review was to assess the efficacy and safety of lenalidomide monotherapy in these patients.MethodsMEDLINE, EMBASE, and the Cochrane Library databases were searched for publications up to April 7, 2021. Original studies that had information on lenalidomide monotherapy for DLBCL patients with R/R status were included. Meta-analyses of response rates, adverse events (AEs), overall survival (OS), and progression-free survival

Is a Good Sleep on Mosquito-Free Nights Worth the Risk of Lymphoma Associated with the Use of Household Insecticides? A Case-Control Study of Lymphoma Subtypes in Adults.

BackgroundThe evidence linking the use of household pesticides and the risk of lymphoma is scanty.MethodsWe explored the hypothesis in a population-based case-control study on lymphoma conducted in Sardinia, Italy, in 1998-2004, including 325 cases and 465 population controls and data on lifetime frequency, seasonality, and years of use of household insecticides and potential confounders. We calculated the risk of lymphoma (all subtypes) and its major subtypes associated with using household insecticides in three time windows (up to 1978, from 1979-2001, and 2002 onwards) with unconditional lo

Proteomic analysis of plasma proteins of high-flux haemodialysis and on-line haemodiafiltration patients reveals differences in transthyretin levels related with anaemia.

A large proportion of end-stage renal disease (ESRD) patients under long-term haemodialysis, have persistent anaemia and require high doses of recombinant human erythropoietin (rhEPO). However, the underlying mechanisms of renal anaemia have not been fully elucidated in these patients. In this study, we will be focusing on anaemia and plasma proteins in ESRD patients on high-flux haemodialysis (HF) and on-line haemodiafiltration (HDF), to investigate using two proteomic approaches if patients undergoing these treatments develop differences in their plasma protein composition and how this could

Cyclic nucleotide phosphodiesterases as drug targets.

Cyclic nucleotides are synthesized by adenylyl and/or guanylyl cyclase, and downstream of this synthesis, the cyclic nucleotide phosphodiesterase families (PDEs) specifically hydrolyze cyclic nucleotides. PDEs control cyclic adenosine-3',5'monophosphate (cAMP) and cyclic guanosine-3',5'-monophosphate (cGMP) intracellular levels by mediating their quick return to the basal steady state levels. This often takes place in subcellular nanodomains. Thus, PDEs govern short-term protein phosphorylation, long-term protein expression, and even epigenetic mechanisms by modulating cyclic nucleotide levels

Inherited Platelet Disorders: An Updated Overview.

Platelets play a major role in hemostasis as ppwell as in many other physiological and pathological processes. Accordingly, production of about 1011 platelet per day as well as appropriate survival and functions are life essential events. Inherited platelet disorders (IPDs), affecting either platelet count or platelet functions, comprise a heterogenous group of about sixty rare diseases caused by molecular anomalies in many culprit genes. Their clinical relevance is highly variable according to the specific disease and even within the same type, ranging from almost negligible to life-threateni

Географическая связь множественного склероза и амиотропического бокового склероза.

Амиотрофический боковой склероз (ALS) и множественный склероз (MS) являются разрушительными, неизлечимыми нейродегенеративными заболеваниями, которые в значительной степени считаются неизвестными этиологами. Хотя эти болезни имеют некоторые сходства, они, как правило, не считаются тесно связанными между собой. У них разные патологические маркеры и разные прогнозы. Кроме того, MS (но не ALS) считается аутоиммунным заболеванием. Кроме того, уже давно отмечается, что НР имеет мощный градиент север-юг в своем распределении, в то время как лишь недавно стало известно о таком градиенте в БАС. Вместе

Iron in the Tumor Microenvironment-Connecting the Dots.

Iron metabolism and tumor biology are intimately linked. Iron facilitates the production of oxygen radicals, which may either result in iron-induced cell death, ferroptosis, or contribute to mutagenicity and malignant transformation. Once transformed, malignant cells require high amounts of iron for proliferation. In addition, iron has multiple regulatory effects on the immune system, thus affecting tumor surveillance by immune cells. For these reasons, inconsiderate iron supplementation in cancer patients has the potential of worsening disease course and outcome. On the other hand, chronic im

Convergent targeting of FUNDC1-dependent mitophagy sensitises and overcomes resistance to EGFR inhibition.

Combination therapies are critical for enhancing and prolonging the efficacy of EGFR inhibitors. Here, we uncover FUNDC1-dependent mitophagy as a key protective mechanism in EGFR-mutant non-small cell lung cancer (NSCLC). We discover that nitidine, a bioactive component of the traditional Xihuang Pill formulation, synergises with the EGFR inhibitor osimertinib. Mechanistically, nitidine and osimertinib synergistically disrupt FUNDC1-mediated mitophagy, leading to mitochondrial dysfunction and accumulation of reactive oxygen species in EGFR-mutant NSCLC. We further show that both osimertinib an

Ассоциированные клетки B в аутоиммунных болезнях: патогенез и клинические последствия.

Будучи разнородным подмножеством клеток В, связанные с возрастом клетки В (ABC) имеют различные транскрипционные профили, процессы экстрафолликулярной дифференциации и множественные функции в автоматическом иммунитете. Сигналы TLR7 и TLR9 наряду с стимуляцией IFN-__ и IL-21 имеют важное значение для дифференциации ABC, которая также регулируется хемокиновыми рецепторами, включая CXCR3 и CCR2, и интегралами, включая CD11b и CD11c. С учетом их функций, связанных с поглощением и представлением антигенов, секрецией цитокина, а также активацией ячеек Т, ABC демонстрируют потенциал в прогнозе, диагн

Proteomic analysis of MSC-derived apoptotic vesicles identifies Fas inheritance to ameliorate haemophilia a via activating platelet functions.

Apoptotic vesicles (apoVs) are apoptotic cell-derived nanosized vesicles that play a crucial role in multiple pathophysiological settings. However, their detailed characteristics, specific surface markers, and biological properties are not fully elucidated. In this study, we compared mesenchymal stem cell (MSC)-derived apoVs and exosomes from three different types of MSCs including human bone marrow MSCs (hBMSCs), human adipose MSCs (hASCs), and mouse bone marrow MSCs (mBMSCs). We established a unique protein map of MSC-derived apoVs and identified the differences between apoVs and exosomes in

Lenalidomide and Pomalidomide Improve Function and Induce FcγRI/CD64 in Multiple Myeloma Neutrophils.

Background Myeloid dysfunction is an emerging hallmark of microenvironment changes occurring in multiple myeloma (MM). Our previous work showed that FcγRI/CD64 overexpression in neutrophils of newly diagnosed MM patients is associated to inferior outcomes, reduced oxidative bursts and phagocytosis, with an increased risk of bacterial infections. Pomalidomide is a novel immune-modulatory drug approved for relapsed/refractory patients (RRMM), with drug-related neutropenia as major limitation to treatment. Patients and methods Herein, we describe a prospective analysis of 51 consecutive RRMM pati

Fibromyalgia syndrome: etiology, pathogenesis, diagnosis, and treatment.

Fibromyalgia syndrome is mainly characterized by pain, fatigue, and sleep disruption. The etiology of fibromyalgia is still unclear: if central sensitization is considered to be the main mechanism involved, then many other factors, genetic, immunological, and hormonal, may play an important role. The diagnosis is typically clinical (there are no laboratory abnormalities) and the physician must concentrate on pain and on its features. Additional symptoms (e.g., Raynaud's phenomenon, irritable bowel disease, and heat and cold intolerance) can be associated with this condition. A careful differen
