Developing giant plasma membrane vesicles from Leishmania cells to investigate the role of membrane proteins in photodynamic inactivation

Photochemistry and Photobiology, EarlyView.
In this study, we developed giant plasma membrane vesicles (GPMVs) from Leishmania amazonensis promastigote membranes to investigate the role of protein‐embedded membranes in methylene blue (MB) photooxidation. Upon MB photoactivation in model lipid membranes (giant unilamellar vesicles, GUVs), a distinct photooxidation effect was observed, marked by ...

Immunomodulatory effects of photodynamic therapy for skin cancer: Potential strategies to improve treatment efficacy and tolerability

Photochemistry and Photobiology, EarlyView.
Photodynamic therapy (PDT) is a nonscarring treatment modality that is widely used for skin cancers and early squamous precursor lesions. PDT was previously thought to work primarily by killing cancer cells directly (via apoptosis or necrosis). However, more recent work indicates that a significant mechanism for PDT is the stimulation of anti‐cancer ...

Longitudinal metabolomics study of phosphate‐adenine‐guanosine‐glucose‐saline‐mannitol stored red blood cells

Transfusion, EarlyView.
Abstract Background The storage of red blood cells (RBCs) is essential for transfusion but leads to storage lesions that compromise RBC quality and increase the risk of transfusion‐related adverse effects, including allergic transfusion reactions (ATRs). Understanding storage‐induced metabolic change is crucial for enhancing transfusion safety.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Aging‐Derived Alterations in Genomic, Immune, and Metabolic Networks: Implications for Cancer Development and Therapy

MedComm – Oncology, Volume 5, Issue 1, March 2026.
Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.

Trifunctional sphingomyelin derivatives enable nanoscale resolution of sphingomyelin turnover in physiological and infection processes via expansion microscopy

Nature Communications
Sphingomyelin is a key molecule of sphingolipid metabolism, and its enzymatic breakdown is associated with various infectious diseases. Here, we introduce trifunctional sphingomyelin derivatives that enable the visualization of sphingomyelin distribution
