New Frontiers in Asthma Chest Imaging.

Modern pulmonary imaging can reveal underlying pathological and pathophysiological changes in the lungs of people with asthma, with important clinical implications. A multitude of imaging modalities are now used to examine underlying structure/function relationships including computed tomography, magnetic resonance imaging, optical coherence tomography, and endobronchial ultrasound. Imaging-based biomarkers from these techniques, including airway dimensions, blood vessel volumes, mucus scores, ventilation defect extent and air trapping extent, often have increased sensitivity compared to traditional lung function measurements, and are increasingly used as endpoints in clinical trials.

HuR inhibition overcomes cFLIP-mediated doxorubicin resistance in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) presents therapeutic challenges due to limited targeted treatment options and resistance to chemotherapy drugs, such as doxorubicin. This study investigated doxorubicin resistance mechanisms and a strategy to overcome it. A doxorubicin-resistant cell subline (231-DR) was developed from MDA-MB-231 TNBC cells, and enhanced expression of cellular FLICE-inhibitory protein (cFLIP) in 231-DR cells was identified as a potential driver of the resistance.

Loss of MK2 Enhances Radiation-Mediated Apoptosis in Bladder Cancer.

Background: Bladder cancer patients unable to receive cystectomy or who choose to pursue organ-sparing approach are managed with definitive (chemo)radiotherapy. However, this standard of care has not evolved in decades and disease recurrence and survival outcomes remain poor. Identifying novel therapies to combine with radiotherapy (RT) is therefore paramount to improve overall patient outcomes and survival.

The current socioeconomic and regulatory landscape of immune effector cell therapies.

Immune cell effector therapies, including chimeric antigen receptor (CAR)-T cells, T-cell receptor (TCR) T cells, natural killer (NK) cells, and macrophage-based therapies, represent a transformative approach to cancer treatment, harnessing the immune system to target and eradicate malignant cells. CAR-T cell therapy, the most established among these, involves engineering T cells to express CARs specific to cancer cell antigens, showing remarkable efficacy in hematologic malignancies like leukemias, B-cell lymphomas, and multiple myeloma. Similarly, TCR-modified therapies, which reprogram T cells to recognize intracellular tumor antigens presented by major histocompatibility complex (MHC) molecules, offer promise for a range of solid tumors.
