Clozapine has superior efficacy in the treatment of refractory schizophrenia; however, use of clozapine is limited due to severe side effects, including myocarditis. Using non-integrative Sendai virus, we generated induced pluripotent stem cell lines from peripheral blood mononuclear cells of two patients with refractory schizophrenia, one clozapine-tolerant and one clozapine-induced myocarditis. Both cell lines exhibited a normal karyotype and pluripotency was validated by flow cytometry, immunofluorescence and their ability to differentiate into the three germ layers. These lines can be used to generate 2D and 3D patient-specific human cellular models to identify the mechanism by which clozapine induces myocardial inflammation.

Background: Diabetes mellitus (DM), a chronic metabolic disease, is characterized by long-term hyperglycemia resulting from the defect of insulin production and insulin resistance. The damage and dysfunction of pancreatic β-cells is a main link in DM development.

Methods: In this work, pancreatic β-cell line INS-1E cells were exposed to 30 mM glucose for 48 h to construct an in vitro DM model.

Inflammation-proliferation transition plays a key role in the successful healing of a common burn type, second-degree burn. Gynura procumbens in vitro adventitious root nanohydrogel is currently being studied for its immunomodulatory to improve reparative environment. Root production and nanohydrogel preparation was done respectively by in vitro propagation and emulsion/ solvent diffusion with carbomer as a polymer.

Antiproliferative effect of hydroalcoholic brown propolis extract on tumor and non-tumor cells.

Studies show that propolis has antimicrobial, antifungal, antiviral, anti-inflammatory, antioxidant, antitumor, and immunomodulatory properties, and may protect against diseases such as diabetes, cardiovascular disease, and cancer. We aimed to extract compounds of brown propolis with hydroalcoholic solvents and evaluate their cytotoxic activity on tumor and non-tumor cells by MTT test. We tested the solute:solvent ratio (ethanol:water) and extraction time in a Shaker incubator (710 rpm) before conducting a central composite rotational design (CCRD) to optimize time and solvent mixture.

SMARCA4 regulates the NK-mediated killing of senescent cells.

MRC Laboratory of Medical Sciences (LMS), Du Cane Road, London W12 0NN, UK.

Induction of senescence by chemotherapeutic agents arrests cancer cells and activates immune surveillance responses to contribute to therapy outcomes. In this investigation, we searched for ways to enhance the NK-mediated elimination of senescent cells. We used a staggered screen approach, first identifying siRNAs potentiating the secretion of immunomodulatory cytokines to later test for their ability to enhance NK-mediated killing of senescent cells.

Amphiphilic hemicyanine molecular probes crossing the blood-brain barrier for intracranial optical imaging of glioblastoma.

Sci Adv

January 2025

Medical Research Institute, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou 510080, China.

Intracranial optical imaging of glioblastoma (GBM) is challenging due to the scarcity of effective probes with blood-brain barrier (BBB) permeability and sufficient imaging depth. Herein, we describe a rational strategy for designing optical probes crossing the BBB based on an electron donor-π-acceptor system to adjust the lipid/water partition coefficient and molecular weight of probes. The amphiphilic hemicyanine dye (namely, IVTPO), which exhibits remarkable optical properties and effective BBB permeability, is chosen as an efficient fluorescence/photoacoustic probe for in vivo real-time imaging of orthotopic GBM with high resolution through the intact skull.
