Granulocyte Colony Stimulating Factor-Mobilized Peripheral Blood Mononuclear Cells: An Alternative Cellular Source for Chimeric Antigen Receptor Therapy.

Lymphocyte collection by apheresis for CAR-T production usually does not include blood mobilized using granulocyte colony stimulating factor (G-CSF) due to the widespread knowledge that it causes a decrease in the number and functionality of lymphocytes. However, it is used for stem cell transplant, which is a common treatment for hematological malignancies. The growing demand for CAR therapies (CAR-T and NK-CAR), both in research and clinics, makes it necessary to evaluate whether mobilized PBSC products may be potential candidates for use in such therapies. This review collects recent works

Совершенствование иммунотерапии клеток ИНКТ путем интеграции оптимизированных эндодоменов ЦАР и участников ИНКТ.

Клетки ИНКТ становятся весьма перспективной платформой иммунотерапии для лечения рака. Чтобы максимально увеличить антираковую активность CAR-INKT против рака крови, мы изучили оптимальные конструкции CAR и их комбинацию с новыми специфичными участниками INKT. Мы находим, что среди пяти различных эндодомен ЦАР, подкрепляемых возросшей вспыльчивостью и перекрестным разговором между Plexin D1 на CAR-INKT и Semaphorin 4 A на клетках миэломы, BCMA CD28z CAR-INKT проявляет наибольшую активность против миэломы. В частности, CD28z CAR-INKT опережает их коллег CAR-T. В целях расширения потенциала CAR-

The Contribution of Tumor Derived Exosomes to Cancer Cachexia.

Cancer cachexia is defined as unintentional weight loss secondary to neoplasia and is associated with poor prognosis and outcomes. Cancer cachexia associated weight loss affects both lean tissue (i.e., skeletal muscle) and adipose tissue. Exosomes are extracellular vesicles that originate from multivesicular bodies that contain intentionally loaded biomolecular cargo. Exosome cargo includes proteins, lipids, mitochondrial components, and nucleic acids. The cargo carried in exosomes is thought to alter cell signaling when it enters into recipient cells. Virtually every cell type secretes exosom

Screening the Active Phytochemicals From Eclipta prostrata and Unraveling Their Molecular Insight Into Human Malignancies.

Current drugs against multiple human malignancies are limited, and developing new treatment strategies is improbable within a short time. So, considering the current situation, phytochemicals could be a viable option for developing chemotherapeutic agents for managing numerous types of malignancies. Therefore, we aimed to locate all phytochemicals of Eclipta prostrata and unravel their chemotherapeutic mechanisms and strategies individually. We defined 25 active compounds based on their anticancer activities after filtering through IMPPAT and literature search, and these compounds have chemoth

Natural bioactive molecules and chemotherapeutics synergism for enhanced cancer therapy.

AIMS/OBJECTIVES: This review highlights evidence on natural bioactive compounds, including polyphenols, alkaloids, terpenoids, and fungal metabolites, as adjuvants to standard chemotherapeutics, with objectives to: first, delineate mechanisms by which these agents enhance cytotoxic efficacy and o

Decoding the epitranscriptome: a new frontier for cancer therapy and drug resistance.

As the role of RNA modification in gene expression regulation and human diseases, the "epitranscriptome" has been shown to be an important player in regulating many physiological and pathological processes. Meanwhile, the phenomenon of cancer drug resistance is becoming more and more frequent, especially in the case of cancer chemotherapy resistance. In recent years, research on relationship between post-transcriptional modification and cancer including drug resistance has become a hot topic, especially the methylation of the sixth nitrogen site of RNA adenosine-m6A (N6-methyladenosine). m6A m

The therapeutic role of γδT cells in TNBC.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer that presents significant therapeutic challenges due to the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression. As a result, conventional hormonal and targeted therapies are largely ineffective, underscoring the urgent need for novel treatment strategies. γδT cells, known for their robust anti-tumor properties, show considerable potential in TNBC treatment as they can identify and eliminate tumor cells without reliance on MHC restrictions. These cells de

Pectin: A Bioactive Food Polysaccharide with Cancer Preventive Potential.

Pectin is an acidic heteropolysaccharide found in the cell walls and the primary and middle lamella of land plants. To be authorized as a food additive, industrial pectins must meet strict guidelines set forth by the Food and Agricultural Organization and must contain at least 65% polygalacturonic acid to achieve the E440 level. Fruit pectin derived from oranges or apples is commonly used in the food industry to gel or thicken foods and to stabilize acid-based milk beverages. It is a naturally occurring component and can be ingested by dietary consumption of fruit and vegetables. Preventing lo

Ferroptosis and its emerging role in esophageal cancer.

The occurrence and development of tumors involve a series of life activities of cells, among which cell death has always been a crucial part in the research of tumor mechanisms and treatment methods. Ferroptosis is a non-apoptotic form of cell death, which is characterized by lipid peroxidation accumulation and further cell membrane rupture caused by excessive production of intracellular oxygen free radicals dependent on iron ions. Esophageal cancer is one of the common digestive tract tumors. Patients in the early stage are mainly treated with surgery, and the curative effect is awe-inspiring

Co-inhibition of NF-κB and JNK is synergistic in TNF-expressing human AML.

Leukemic stem cells (LSCs) isolated from acute myeloid leukemia (AML) patients are more sensitive to nuclear factor κB (NF-κB) inhibition-induced cell death when compared with hematopoietic stem and progenitor cells (HSPCs) in in vitro culture. However, inadequate anti-leukemic activity of NF-κB inhibition in vivo suggests the presence of additional survival/proliferative signals that can compensate for NF-κB inhibition. AML subtypes M3, M4, and M5 cells produce endogenous tumor necrosis factor α (TNF). Although stimulating HSPC with TNF promotes necroptosis and apoptosis, similar treatment wi

Metabolic Alterations in Cancer Cells and the Emerging Role of Oncometabolites as Drivers of Neoplastic Change.

The mitochondrion is an important organelle and provides energy for a plethora of intracellular reactions. Metabolic dysregulation has dire consequences for the cell, and alteration in metabolism has been identified in multiple disease states-cancer being one. Otto Warburg demonstrated that cancer cells, in the presence of oxygen, undergo glycolysis by reprogramming their metabolism-termed "aerobic glycolysis". Alterations in metabolism enable cancer cells to gain a growth advantage by obtaining precursors for macromolecule biosynthesis, such as nucleic acids and lipids. To date, several molec

Targeted Hybrid Nanocarriers as Co-Delivery Systems for Enhanced Cancer Therapy.

Hybrid nanocarriers have realized a growing interest in drug delivery research because of the potential of being able to treat, manage or cure diseases that previously had limited therapy or cure. Cancer is currently considered the second leading cause of death globally. This makes cancer therapy a major focus in terms of the need for efficacious and safe drug formulations that can be used to reduce the rate of morbidity and mortality globally. The major challenge encountered over the years with cancer chemotherapy is the non-selectivity of anticancer drugs, leading to severe adverse effects i

Genome-edited allogeneic CAR-T cells: the next generation of cancer immunotherapies.
