Depletion of Cholesterol Reduces ENaC Activity by Decreasing Phosphatidylinositol-4,5-Bisphosphate in Microvilli

Cellular Physiology and Biochemistry, 2018
Background/Aims: The epithelial sodium channel (ENaC) in cortical collecting duct (CCD) principal cells plays a critical role in regulating systemic blood pressure.

Resource quantity affects infection success and impacts of a microsporidian on hosts

Oikos, Volume 2026, Issue 2, February 2026.
Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...

Distinct Roles of SLC26A3 and CFTR in Surface pH Regulation and Bicarbonate Secretion in Human Intestinal Epithelium

Acta Physiologica, Volume 242, Issue 2, February 2026.
ABSTRACT Background and Aims Colonic bicarbonate secretion is mediated by the chloride/bicarbonate exchanger SLC26A3 and the cystic fibrosis transmembrane conductance regulator (CFTR). Dysfunction of either causes luminal acidosis, altered mucus properties, and inflammation.

Immunohistochemical Analysis of Tom20 in Choroid Plexus Epithelial Cells From Elderly Brains With Neurodegenerative Diseases

Neuropathology, Volume 46, Issue 1, February 2026.
ABSTRACT The choroid plexus (CP) contributes to cerebrospinal fluid (CSF) production and regulation of circadian rhythm. Recently, many neuroimaging studies have reported enlarged CP volumes in patients with neurodegenerative diseases, including Alzheimer's disease (AD).

The ultrastructural characteristics of bile canaliculus in porcine liver donated after cardiac death and machine perfusion preservation.

PLoS ONE, 2020
The effects of each type of machine perfusion preservation (MP) of liver grafts donated after cardiac death on the bile canaliculi of hepatocytes remain unclear.

ICAM-1 nanoclusters regulate hepatic epithelial cell polarity by leukocyte adhesion-independent control of apical actomyosin

eLife
Epithelial intercellular adhesion molecule (ICAM)-1 is apically polarized, interacts with, and guides leukocytes across epithelial barriers. Polarized hepatic epithelia organize their apical membrane domain into bile canaliculi and ducts, which are not ...

chaoptin, prominin, eyes shut and crumbs form a genetic network controlling the apical compartment of Drosophila photoreceptor cells

Biology Open, 2014
The apical surface of epithelial cells is often highly specialised to fulfil cell type-specific functions. Many epithelial cells expand their apical surface by forming microvilli, actin-based, finger-like membrane protrusions.

Remodeling of the Intestinal Brush Border Underlies Adhesion and Virulence of an Enteric Pathogen

mBio, 2014
Intestinal colonization by Vibrio parahaemolyticus—the most common cause of seafood-borne bacterial enteritis worldwide—induces extensive disruption of intestinal microvilli.

T cell microvilli constitute immunological synaptosomes that carry messages to antigen-presenting cells

Nature Communications, 2018
Microvilli can participate in adhesion or migration of T cells, but whether they are involved in function regulation is unclear. Here the authors show that T cell microvilli form budding vesicles containing T cell signalling components for deposition ...

Ultrastructure of the digestive system of Ramazzottius tribulosus and Macrobiotus richtersi (Eutardigrada) in relationship with diet

Journal of Limnology, 2007
The ultrastructure of the digestive system of tardigrades was already described in some species, but it has never been studied in relationship to diet.
