Release of cholesterol-rich particles from the macrophage plasma membrane during movement of filopodia and lamellipodia. [PDF]

, 2019
Cultured mouse peritoneal macrophages release large numbers of ~30-nm cholesterol-rich particles. Here, we show that those particles represent fragments of the plasma membrane that are pulled away and left behind during the projection and retraction of ...

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, Volume 13, Issue 25, 4 May 2026.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, Volume 13, Issue 25, 4 May 2026.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

Characterization of an influenza virus pseudotyped with Ebolavirus glycoprotein [PDF]

, 2018
We have produced a new Ebola virus pseudotype: E-S-FLU, which can be handled in biosafety level-1/2 containment for laboratory analysis. E-S-FLU is a single cycle influenza virus coated with Ebolavirus glycoprotein, and it encodes enhanced green ...

Adults With Acid Sphingomyelinase Deficiency Have Sustained Improvements in Clinical Outcomes With up to 5 Years of Olipudase Alfa Enzyme Replacement Therapy: ASCEND Trial Final Results

Journal of Inherited Metabolic Disease, Volume 49, Issue 3, May 2026.
ABSTRACT Acid sphingomyelinase deficiency (ASMD) is a rare debilitating lysosomal storage disease resulting in multisystemic disease manifestations, significant disease burden, and early mortality for some individuals. Enzyme replacement therapy (ERT) with olipudase alfa (Xenpozyme) is the first disease‐specific treatment indicated for noncentral ...

Acidic pH and acidic enzymes in atherosclerosis [PDF]

, 2010
Atherosclerosis is an inflammatory disease characterized by accumulation of lipids and fibrous connective tissue in the arterial wall. Recently, it has been suggested that decrease in the pH of extracellular fluid of the arterial intima may enhance LDL ...

Lysosomal cholesterol accumulation sensitizes to acetaminophen hepatotoxicity by impairing mitophagy.

, 2015
The role of lysosomes in acetaminophen (APAP) hepatotoxicity is poorly understood. Here, we investigated the impact of genetic and drug-induced lysosomal cholesterol (LC) accumulation in APAP hepatotoxicity.

Virological aspects of Epstein-Barr virus infections. [PDF]

, 2005
Epstein-Barr virus (EBV) is usually maintained in an asymptomatic and latent form by the host immune system, and primarily by EBV-specific cytotoxic T cells (CTLs).

Coronavirus Nsp3 Hijacks CLTC to Modulate Autophagosome Nucleation for Promoting DMV Formation and Viral Replication

Advanced Science, Volume 13, Issue 24, 27 April 2026.
In wild‐type cells, FIPV infection recruits CLTC to nsp3, facilitates DMV biogenesis and block autophagic flux to promote viral replication. CLTC knockout impairs autophagosome nucleation by reducing Beclin1–ATG14 complex expression. This disrupts the formation of autophagic precursor membranes, thereby preventing their hijacking by nsp3 for DMV ...

Theoretical Study of Sphingomyelinases from Entamoeba histolytica and Trichomonas vaginalis Sheds Light on the Evolution of Enzymes Needed for Survival and Colonization

Pathogens
The path to survival for pathogenic organisms is not straightforward. Pathogens require a set of enzymes for tissue damage generation and to obtain nourishment, as well as a toolbox full of alternatives to bypass host defense mechanisms.
