Harnessing nanomaterials to precisely regulate the immunosuppressive tumor microenvironment for enhanced immunotherapy

BMEMat, EarlyView.
The immunosuppressive tumor microenvironment, characterized by hypoxia, redox imbalance, elevated interstitial fluid pressure, and acidity, was comprehensively elucidated. This review discussed the etiology and consequences of the characteristics of the immunosuppressive tumor microenvironment, and analyzed the recent advancements in nanomaterials for ...

Serum albumin acts as a shuttle to enhance cholesterol efflux from cells[S]

Journal of Lipid Research, 2013
An important mechanism contributing to cell cholesterol efflux is aqueous transfer in which cholesterol diffuses from cells into the aqueous phase and becomes incorporated into an acceptor particle.

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

BMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

Plasma cholesterol efflux capacity from human THP-1 macrophages is reduced in HIV-infected patients: impact of HAART[S]

Journal of Lipid Research, 2015
The capacity of HDL to remove cholesterol from macrophages is inversely associated with the severity of angiographic coronary artery disease. The effect of human immunodeficiency virus (HIV) infection or its treatment on the ability of HDL particles to ...

Increasing phospholipid biomimicry governs water permeability in droplet interface bilayers

Droplet, EarlyView.
Increasing phospholipid biomimicry in droplet interface bilayers alters how membranes respond to “membrane‐active molecules” such as cholesterol and niacin. This shows that membranes made using synthetic lipids can overestimate small‐molecule effects, highlighting the importance of using biomimetic lipid compositions to improve physiological relevance ...

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

Serum, but not monocyte macrophage foam cells derived from low HDL-C subjects, displays reduced cholesterol efflux capacity

Journal of Lipid Research, 2009
The main antiatherogenic function of HDL is to promote the efflux of cholesterol from peripheral cells and transport it to the liver for excretion in a process termed reverse cholesterol transport.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
