ObjectivesIdiopathic pulmonary fibrosis (IPF) is a chronic fibrotic lung disease characterized by dry cough, fatigue, and progressive exertional dyspnea. Lung parenchyma and architecture is destroyed, compliance is lost, and gas exchange is compromised in this debilitating condition that leads inexorably to respiratory failure and death within 3-5 years of diagnosis. This review discusses treatment approaches to IPF in current use and those that appear promising for future development.Data sourceThe data were obtained from the Randomized Controlled Trials and scientific studies published in En

Melphalan flufenamide inhibits osteoclastogenesis by suppressing proliferation of monocytes.

Myeloma bone disease is a major complication in multiple myeloma affecting quality of life and survival. It is characterized by increased activity of osteoclasts, bone resorbing cells. Myeloma microenvironment promotes excessive osteoclastogenesis, a process of production of osteoclasts from their precursors, monocytes. The effects of two anti-myeloma drugs, melphalan flufenamide (melflufen) and melphalan, on the activity and proliferation of osteoclasts and their progenitors, monocytes, were assessed in this study. In line with previous research, differentiation of monocytes was associated wi

Engineered cell therapies for autoimmune diseases: evaluating CAR-T and CAR-M progress and prospects.

Autoimmune diseases (AID) comprise a diverse group of disorders driven by aberrant B-cell and T-cell reactivity against self-tissues. In recent years, cell-based therapies utilizing engineered T cells have emerged as a promising therapeutic strategy for AIDs. Notably, chimeric antigen receptor (CAR)-T cells have demonstrated the ability to selectively target and eliminate autoreactive immune populations, including pathogenic B cells and antibody-producing plasma cells. Beyond T-cell modulation, macrophages (MΦs) exhibit remarkable plasticity, differentiating into pro-inflammatory (M1) or anti-

Specific epigenetic regulators serve as potential therapeutic targets in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF), a disorder observed mostly in older human beings, is characterised by chronic and progressive lung scarring leading to an irreversible decline in lung function. This health condition has a dismal prognosis and the currently available drugs only delay but fail to reverse the progression of lung damage. Consequently, it becomes imperative to discover improved therapeutic compounds and their cellular targets to cure IPF. In this regard, a number of recent studies have targeted the epigenetic regulation by histone deacetylases (HDACs) to develop and categorise

Guided immunotherapy for residual solid tumor: integrating platelets and CAR T cells to reduce post-surgical recurrence.

Postoperative recurrence remains a major obstacle to durable remission in patients with solid tumors, even after complete macroscopic resection. Growing evidence suggests that surgery creates a transient yet highly permissive biological window characterized by inflammatory signaling, coagulation activation, endothelial disruption, and systemic immune suppression. Together, these processes foster a protective niche that enables microscopic residual disease to evade immune surveillance and initiate metastatic outgrowth. Although modern adjuvant therapies have improved outcomes, their effectivene

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

In vitro расширила человека CD4+CD25+ регуляционные T клетки, подавляющие распространение Т клеток.

Регулирующие Т клетки (Tregs) оказались критически важными в балансе между автоиммунизацией и терпимостью и были связаны с несколькими аутоиммунными заболеваниями человека. Однако небольшое число трегов в периферии крови ограничивает их терапевтический потенциал. Поэтому мы разработали протокол, который позволит расширить "Трегз" при сохранении их подавляющей активности. Мы изолировали клетки CD4+CD25 hi от человеческой периферической крови и расширили их in vitro в присутствии anti-CD3 и anti-CD28 Магнитные кситы и высокие концентрации внешнего интерлейкина (IL) -2. Траги были эффективно расш

The crosstalk network of non-coding RNAs: Emerging opportunities for the clinical application of osteoporosis.

Current methods for testing bone density lack the capability to detect patients with early bone loss, and existing osteoporosis therapies have limitations in their efficacy and safety. Therefore, the development of more precise and convenient diagnostic technologies and novel treatments is of paramount importance. Extracellular vesicle (EV)-mediated non-coding RNA (ncRNA) interaction networks enable both the detection of early bone loss and targeted therapy for enhanced treatment outcomes. In this review, we highlight the utility of EVs for carrying various ncRNAs (e.g., miRNAs, lncRNAs, and c

FK506-Binding Protein 11 Is a Novel Plasma Cell-Specific Antibody Folding Catalyst with Increased Expression in Idiopathic Pulmonary Fibrosis.

Antibodies are central effectors of the adaptive immune response, widespread used therapeutics, but also potentially disease-causing biomolecules. Antibody folding catalysts in the plasma cell are incompletely defined. Idiopathic pulmonary fibrosis (IPF) is a fatal chronic lung disease with increasingly recognized autoimmune features. We found elevated expression of FK506-binding protein 11 (FKBP11) in IPF lungs where FKBP11 specifically localized to antibody-producing plasma cells. Suggesting a general role in plasma cells, plasma cell-specific FKBP11 expression was equally observed in lympha

Effect of pilose antler polypeptide on the mechanism of bone homeostasis in osteoporosis.

Osteoporosis stands out as a prevalent metabolic disorder, bearing significant repercussions on human well-being and overall quality of life. It remains an urgent concern within the global public health framework due to its widespread occurrence. Osteoporosis arises from an abnormal metabolism in osteoblasts and osteoclasts, resulting in a disruption of the delicate equilibrium between bone formation and bone resorption. Within this context, deer antler peptides emerge as natural active compounds, wielding a pivotal role in governing the differentiation, proliferation, and mineralization of os

Inflammatory Microenvironment and Specific T Cells in Myeloproliferative Neoplasms: Immunopathogenesis and Novel Immunotherapies.

The Philadelphia-negative myeloproliferative neoplasms (MPNs) are malignancies of the hematopoietic stem cell (HSC) arising as a consequence of clonal proliferation driven by somatically acquired driver mutations in discrete genes (JAK2, CALR, MPL). In recent years, along with the advances in molecular characterization, the role of immune dysregulation has been achieving increasing relevance in the pathogenesis and evolution of MPNs. In particular, a growing number of studies have shown that MPNs are often associated with detrimental cytokine milieu, expansion of the monocyte/macrophage compar
