Ten-year anemia as initial manifestation of Castleman disease in the abdominal cavity: A case report.

Castleman disease (CD) is a relatively rare lymphoproliferative disorder. Lesions predominantly originate on the chest and neck and rarely occur on the abdomen. A 34-year-old female presented to our hospital with an unexplained 10-year history of anemia. A pathological diagnosis of plasma cell-type CD was established. One cycle of chemotherapy (thalidomide, cyclophosphamide, and prednisolone) improved her anemia significantly. Prompt etiological diagnosis and early intervention are essential to address systemic manifestations in patients with CD, and it is crucial to consider CD as a different

HLA-DPA1 gene is a potential predictor with prognostic values in multiple myeloma.

BackgroundMultiple myeloma (MM) is an incurable hematological tumor, which is closely related to hypoxic bone marrow microenvironment. However, the underlying mechanisms are still far from fully understood. We took integrated bioinformatics analysis with expression profile GSE110113 downloaded from National Center for Biotechnology Information-Gene Expression Omnibus (NCBI-GEO) database, and screened out major histocompatibility complex, class II, DP alpha 1 (HLA-DPA1) as a hub gene related to hypoxia in MM.MethodsDifferentially expressed genes (DEGs) were filtrated with R package "limma".

The role and mechanisms of mesenchymal stem cells in postoperative cognitive dysfunction via immune network regulation.

Postoperative cognitive dysfunction (POCD) is a common neurological complication in elderly patients after surgery. Its pathophysiology is complex. Neuroinflammation, oxidative stress, and immune imbalance are all involved in this process. These changes can affect postoperative recovery and reduce patients' quality of life. As population aging continues to increase, the prevention and treatment of POCD have become important clinical issues. In recent years, mesenchymal stem cells (MSCs) have attracted attention in neurological diseases because of their immunomodulatory and tissue healing abili

Постройте мышцы и защитите миелина.

Множественный склероз (MS) представляет собой хроническое и изнуряющее аутоиммунное заболевание центральной нервной системы (СНС), при котором иммунная реакция, основанная на CNS, разрушает миелин, что приводит к широкому спектру симптомов, включая онемение и покалывание, проблемы зрения, нарушение подвижности и т.д. Oligodendrocytes — это миелионирующие клетки в CNS, которые образуются из олигодендроголовых потомков (OPC) посредством дифференциации. Однако по целому ряду причин ОЗК не проводят различия с олигодендроцитами в РС, и в результате, стимулирование дифференциации ОЗК с олигодендроци

Clinical activity of 9-ING-41, a small molecule selective glycogen synthase kinase-3 beta (GSK-3β) inhibitor, in refractory adult T-Cell leukemia/lymphoma.

GSK-3β is a serine/threonine kinase implicated in tumorigenesis and chemotherapy resistance. GSK-3β blockade downregulates the NF-κB pathway, modulates immune cell PD-1 and tumor cell PD-L1 expression, and increases CD8 + T cell and NK cell function. We report a case of adult T-cell leukemia/lymphoma (ATLL) treated with 9-ING-41, a selective GSK-3β inhibitor in clinical development, who achieved a durable response. A 43-year-old male developed diffuse lymphadenopathy, and biopsy of axillary lymph node showed acute-type ATLL. Peripheral blood flow cytometry revealed a circulating clonal T cell

Baseline platelet-to-lymphocyte ratio is associated with severe immune effector cell-associated toxicities in diffuse large B-cell lymphoma patients receiving anti-CD19 CAR T-cell therapy.

INTRODUCTION: Anti-CD19 chimeric antigen receptor (CAR) T-cell therapy can induce durable remissions in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL); however, severe immune effector cell-associated adverse events, including cytokine release syndrome (CRS) and neurotoxicity, remain major clinical challenges. We investigated whether the platelet-to-lymphocyte ratio (PLR) could serve as a predictive biomarker for severe toxicities. METHODS: In this retrospective study, 15 patients with relapsed or refractory DLBCL treated with tisagenlecleucel were analyzed. PLR was

CRISPR-Cas9 Therapeutics in Early Clinical Development: Delivery and Molecular Diagnostics.

CRISPR-Cas9 has progressed from an experimental tool to a therapeutic modality, marked by the first regulatory approvals of an ex vivo-edited autologous CD34+ hematopoietic stem cell product that induces fetal hemoglobin (CASGEVY/exa-cel). In this narrative review, we synthesize modality-specific molecular diagnostic strategies used across early CRISPR clinical translation. In parallel, early clinical experience has begun to demonstrate the feasibility of in vivo editing, including subretinal delivery for CEP290-associated inherited retinal degeneration (EDIT-101 programme) and hepatocyte-targ

PSMA4 as a Druggable Target in Hidradenitis Suppurativa: Evidence From Mendelian Randomization and Single-Cell Transcriptomics.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with limited treatment options and frequent drug resistance. Novel therapeutic targets are urgently needed. We performed a druggable genome-wide Mendelian randomization (MR) analysis using blood cis-expression quantitative trait locus (eQTL) and HS genome-wide association study (GWAS) data. Colocalization, transcriptomic validation, single-cell RNA sequencing, and cell-cell communication analyses were integrated to explore gene function and cell-type specificity. We identified eight genes that showed significant associations

Understanding and Managing Sepsis in Patients With Cancer in the Era of Antimicrobial Resistance.

Sepsis is a frequent complication in immunosuppressed cancer patients and hematopoietic stem cell transplant recipients that is associated with high morbidity and mortality rates. The worldwide emergence of antimicrobial resistance is of special concern in this population because any delay in starting adequate empirical antibiotic therapy can lead to poor outcomes. In this review, we aim to address: (1) the mechanisms involved in the development of sepsis and septic shock in these patients; (2) the risk factors associated with a worse prognosis; (3) the impact of adequate initial empirical ant

The effects of twenty-four nutrients and phytonutrients on immune system function and inflammation: A narrative review.

BACKGROUND AND AIM: Recently, optimal immune function has become a primary focus of worldwide attention not only in the prevention of chronic disease but also as one strategy to reduce the severity of acute illness. Inflammation, a process largely controlled by the immune system, has long been studied and recognized for its role in chronic disease. Optimizing immune function or managing inflammation using individual nutrients and phytonutrients is not well understood by the average person. Thus, this narrative literature review summarizes many of the more recent findings about how certain nutr

Challenges in the Role of Gammaglobulin Replacement Therapy and Vaccination Strategies for Hematological Malignancy.

Patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are prone to present with antibody production deficits associated with recurrent or severe bacterial infections that might benefit from human immunoglobulin (Ig) (IVIg/SCIg) replacement therapy. However, the original IVIg trial data were done before modern therapies were available, and the current indications do not take into account the shift in the immune situation of current treatment combinations and changes in the spectrum of infections. Besides, patients affected by other B cell malignancies present with similar i

Mitochondrial Dysfunction in Chemotherapy-Induced Peripheral Neuropathy (CIPN).

The mitochondrial dysfunction has a critical role in several disorders including chemotherapy-induced peripheral neuropathies (CIPN). This is due to a related dysregulation of pathways involving calcium signalling, reactive oxygen species and apoptosis. Vincristine is able to affect calcium movement through the Dorsal Root Ganglia (DRG) neuronal mitochondrial membrane, altering its homeostasis and leading to abnormal neuronal excitability. Paclitaxel induces the opening of the mitochondrial permeability transition pore in axons followed by mitochondrial membrane potential loss, increased react

Фенотипический и транскриптомный профили костного мозга на ранней и поздней стадии эритрополии были сопоставлены между здоровы

Deregulation of the EGFR/PI3K/PTEN/Akt/mTORC1 pathway in breast cancer: possibilities for therapeutic intervention.

The EGFR/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway plays prominent roles in malignant transformation, prevention of apoptosis, drug resistance and metastasis. The expression of this pathway is frequently altered in breast cancer due to mutations at or aberrant expression of: HER2, ERalpha, BRCA1, BRCA2, EGFR1, PIK3CA, PTEN, TP53, RB as well as other oncogenes and tumor suppressor genes. In some breast cancer cases, mutations at certain components of this pathway (e.g., PIK3CA) are associated with a better prognosis than breast cancers lacking these mutations. The expression of this pathway and upstre

Epigenetic mechanisms in cardiovascular complications of diabetes: towards future therapies.

The pathophysiological mechanisms of cardiovascular disease and microvascular complications in diabetes have been extensively studied, but effective methods of prevention and treatment are still lacking. In recent years, DNA methylation, histone modifications, and non-coding RNAs have arisen as possible mechanisms involved in the development, maintenance, and progression of micro- and macro-vascular complications of diabetes. Epigenetic changes have the characteristic of being heritable or deletable. For this reason, they are now being studied as a therapeutic target for the treatment of diabe

RHOA at the intersection of inflammation-driven and sporadic colorectal cancer.

In the last decades, colorectal cancer (CRC) has emerged as a global problem, representing approximately 10% of all malignant tumors and the second leading cause of cancer-related death. Colitis-associated cancer (CAC) arises from chronic unresolved inflammation and is typically characterised by poor prognosis. Among key cellular regulators, the small GTPase RHOA controls cytoskeleton dynamics in various cell types and, thereby, key biological processes. Although it has been linked to various diseases, the role of RHOA in cancer remains controversial. RHOA has been proposed as a biomarker in c

Identification of Plasma Protein Biomarkers and Drug Targets for Hematologic Malignancies by Proteome-wide Mendelian Randomization.

Background: It has been reported that the proteome in blood was an important source for biomarker and therapeutic target discovery. However, up to now, few proteomes have been identified with the risk of hematologic malignancies. Methods: Genome-wide association studies (GWASs) including 3,083 plasma proteins are based on data from 54,219 people in the UK Biobank Pharma Proteomics Project (UKB-PPP) and 35,559 individuals from Iceland (deCODE). Genetic correlations with 33 hematologic malignancies were derived from the FinnGen cohort and the UK Biobank Data. Further studies, including Bayesian

Bidirectional Relationship Between Cancer and Heart Failure: Old and New Issues in Cardio-oncology.

The main focus of cardio-oncology has been the prevention and treatment of the cardiac toxicity of chemotherapy and radiotherapy. Furthermore, several targeted therapies have been associated with unexpected cardiotoxic side-effects. Recently, epidemiological studies reported a higher incidence of cancer in patients with heart failure (HF) compared with individuals without HF. On this basis, it has been proposed that HF might represent an oncogenic condition. This hypothesis is supported by preclinical studies demonstrating that hyperactivation of the sympathetic nervous system and renin-angiot

Targeting the two-pore channel 2 in cancer progression and metastasis.

The importance of Ca2+ signaling, and particularly Ca2+ channels, in key events of cancer cell function such as proliferation, metastasis, autophagy and angiogenesis, has recently begun to be appreciated. Of particular note are two-pore channels (TPCs), a group of recently identified Ca2+-channels, located within the endolysosomal system. TPC2 has recently emerged as an intracellular ion channel of significant pathophysiological relevance, specifically in cancer, and interest in its role as an anti-cancer drug target has begun to be explored. Herein, an overview of the cancer-related functions

Physiological Role and Use of Thyroid Hormone Metabolites - Potential Utility in COVID-19 Patients.

Thyroxine and triiodothyronine (T3) are classical thyroid hormones and with relatively well-understood actions. In contrast, the physiological role of thyroid hormone metabolites, also circulating in the blood, is less well characterized. These molecules, namely, reverse triiodothyronine, 3,5-diiodothyronine, 3-iodothyronamine, tetraiodoacetic acid and triiodoacetic acid, mediate both agonistic (thyromimetic) and antagonistic actions additional to the effects of the classical thyroid hormones. Here, we provide an overview of the main factors influencing thyroid hormone action, and then go on t
