Modulation of fibroblast behavior by Leishmania: a pathway to understanding disease progression in cutaneous leishmaniasis

BMC Microbiology
Leishmaniasis is a parasitic infection caused by obligatory intracellular protozoa of the Leishmania genus. Macrophages are the main cell for Leishmania parasites that play a key role in immune response against it.

A Viscous DES‐AAV‐Foxo1 Delivery System With High Transfection Efficiency for the Treatment of Corneal Endothelial Dysfunction by Restoring Mitochondria‐ER Contacts

Advanced Science, EarlyView.
High glucose triggers corneal endothelial dysfunction by impairing FOXO1‐mediated ITPR1 transcription, leading to disrupted mitochondria‐associated membrane (MAM) integrity and defective ER‐to‐mitochondria Ca2+ transfer. This study develops an innovative viscous DES‐AAV‐Foxo1 delivery system with enhanced transfection efficiency. This non‐invasive gene

CD44‐Targeting Hydroxyapatite Nanoparticles (HAP) Induce Mitochondrial Dysfunction‐Driven PANoptosis and Immunogenic Cell Death (ICD) via Ca Overload in Colorectal Cancer

Advanced Science, EarlyView.
ABSTRACT Colorectal cancer (CRC) remains therapeutically challenging due to high metastasis, recurrence, and immunotherapy resistance driven by tumor microenvironment‐mediated immune evasion. Immunogenic cell death (ICD) offers a promising strategy to reshape the immune microenvironment, yet existing ICD inducers suffer from poor targeting efficiency ...

CK2α Deficiency Drives Myocardial Fibrosis via Desmin‐Induced Mitochondrial Dysfunction

Advanced Science, EarlyView.
CK2α preserves mitochondrial homeostasis by phosphorylating Desmin to recruit Cryab, ensuring proper filament assembly. CK2α deficiency disrupts this interaction, causing mitochondrial dysfunction, metabolic shifts, bioenergetic failure, and oxidative stress—ultimately establishing a pro‐fibrotic environment that drives cardiac fibrosis.

The ultrastructure of calcareous cirratulid (Polychaeta, Annelida) tubes [PDF]

Estonian Journal of Earth Sciences, 2009
The entire tube wall of Dodecaceria caulleryi and D. coralii is composed of thin calcareous lamellae with a spherulitic prismatic ultrastructure. In Diplochaetetes mexicanus the tube ultrastructure is similar, but contains also some lamellae with a ...

The fine structure of the midgut epithelium in Xerobiotus pseudohufelandi (Iharos, 1966) (Tardigrada, Eutardigrada, Macrobiotidae)

Journal of Limnology, 2013
The aims of our studies were to describe the ultrastructure of the midgut epithelial cells of the eutardigrade Xerobiotus pseudohufelandi and to determine if there are any differences in the ultrastructure of midgut epithelial cells between males and ...
