Decoding tumor microenvironment: EMT modulation in breast cancer metastasis and therapeutic resistance, and implications of novel immune checkpoint blockers.

Tumor microenvironment (TME) and epithelial-mesenchymal transition (EMT) play crucial roles in the initiation and progression of tumors. TME is composed of various cell types, such as immune cells, fibroblasts, and endothelial cells, as well as non-cellular components like extracellular matrix (ECM) proteins and soluble factors. These elements interact with tumor cells through a complex network of signaling pathways involving cytokines, growth factors, metabolites, and non-coding RNA-carrying exosomes.

Adeno-Associated Viral Vectors in the Treatment of Epilepsy.

Epilepsy is a brain disorder characterized by a persistent predisposition to epileptic seizures. With various etiologies of epilepsy, a significant proportion of patients develop pharmacoresistance to antiepileptic drugs, which necessitates the search for new therapeutic methods, in particular, using gene therapy. This review discusses the use of adeno-associated viral (AAV) vectors in gene therapy for epilepsy, emphasizing their advantages, such as high efficiency of neuronal tissue transduction and low immunogenicity/cytotoxicity.

MORE ON DEEP HEMATOMAS IN PATIENTS WITH COVID-19: CASE SERIES.

Background: Despite the fact that the COVID-19 epidemic has already ended, there is no clear answer to the question - what is the nature of the imbalance in the hemocoagulation system, and which phenomena prevail - thrombosis or hemorrhage? More and more new works appear describing the occurrence of deep, extensive hematomas in patients with COVID-19. However, this experience requires further discussion and understanding.

Case Description: From October 2020 to January 2021, 7 (2,1% among all hospitalized with COVID-19 in this period) patients with developed hematomas were observed at the COVID-19 hospital.

Sources and Methods for the Production of Xyloglucan, a Promising Stimulus-Sensitive Biopolymer: A Review.

Xyloglucan is a highly promising 'green' polymer that has found its application in the food and pharmaceutical industries. Due to its molecular structure similarity to mucin, it has remarkable mucoadhesion properties, which has led to a high research interest in this excipient for the development of transmucosal delivery systems. Thermosensitivity is another promising property of xyloglucan derivatives, which is mainly exhibited by synthetic block copolymers such as pluronics and PLGA derivatives.

Emerging insights into epigenetics and hematopoietic stem cell trafficking in age-related hematological malignancies.

Background: Hematopoiesis within the bone marrow (BM) is a complex and tightly regulated process predominantly influenced by immune factors. Aging, diabetes, and obesity are significant contributors to BM niche damage, which can alter hematopoiesis and lead to the development of clonal hematopoiesis of intermediate potential (CHIP). Genetic/epigenetic alterations during aging could influence BM niche reorganization for hematopoiesis or clonal hematopoiesis.

Breaking the shield of solid tumors: a combined approach for enhanced efficacy of CAR-T cells.

The use of chimeric antigen receptor (CAR)-T cells has enhanced the range of available therapeutic modalities in the context of cancer treatment. CAR-T cells have demonstrated considerable efficacy in the targeted eradication of blood cancer cells, thereby stimulating substantial interest in the advancement of such therapeutic approaches. However, the efficacy of CAR-T cells against solid tumor cells has been limited due to the presence of various obstacles.
