Static and dynamic lengths of neutrophil microvilli [PDF]

Proceedings of the National Academy of Sciences, 1998
Containing most of the L-selectin and P-selectin glycoprotein ligand-1 (PSGL-1) on their tips, microvilli are believed to promote the initial arrest of neutrophils on endothelium. At the rolling stage following arrest, the lifetimes of the involved molecular bonds depend on the pulling force imposed by the shear stress of blood flow. With two different

Engineered Bacterial Outer Membrane Vesicles Hitchhiking on Neutrophils for Antibody Drug Delivery to Enhance Postoperative Immune Checkpoint Therapy

Advanced Science, EarlyView.
This study employs neutrophils for the precise delivery of anti‐CD47 antibodies, combined with bacterial outer membrane vesicles, to enhance macrophage phagocytic function in the tumor microenvironment. This approach effectively activates T‐cell anti‐tumor immune responses and significantly reduces the risk of postoperative tumor recurrence and ...

Biophysical modelling of a drosophila photoreceptor [PDF]

, 2009
It remains unclear how visual information is co-processed by different layers of neurons in the retina. In particular, relatively little is known how retina translates vast environmental light changes into neural responses of limited range.

Small and large intestine express a truncated Dab1 isoform that assembles in cell-cell junctions and co-localizes with proteins involved in endocytosis [PDF]

, 2018
Disabled-1 (Dab1) is an essential intracellular adaptor protein in the reelin pathway. Our previous studies in mice intestine showed that Dab1 transmits the reelin signal to cytosolic signalling pathways.

Intestinal responses in pacu (Piaractus mesopotamicus) exposed to fasting and refeeding nutritional management

The Anatomical Record, EarlyView.
Abstract Fasting is a practice in the aquaculture industry that aims to reduce feed costs. This practice can affect the gastrointestinal system of fish. The intestine plays a pivotal role in the nutrition and overall health of fishes. The present study sought to evaluate the effects of fasting and refeeding on body weight, intestine somatic index (ISI),

Nature's conveyor belt - the matrix mediated biomineralization of magnetite in chitons (Mollusca) [PDF]

, 2009
Chitons are marine molluscs that use a variety of iron and calcium based minerals to harden their teeth, which they use to scrape algae growing upon, and within, rocks.

The ductal network in the human testis and epididymis: What belongs to which?

Clinical Anatomy, EarlyView.
Abstract The testes and epididymis are traversed by a system of tubules in which sperm cells are generated, matured, nourished, and transported. Among these are the efferent ductules, which connect the rete testis to the duct of the epididymis. In the Terminologia Anatomica (TA), the efferent ductules are assigned to the testicles, while numerous ...

Origin and evolution of microvilli

Biology of the Cell
AbstractBackground InformationMicrovilli are finger‐like, straight, and stable cellular protrusions that are filled with F‐actin and present a stereotypical length. They are present in a broad range of cell types across the animal tree of life and mediate several fundamental functions, including nutrient absorption, photosensation, and mechanosensation.

Extracellular vesicles and microvilli in the immune synapse

Frontiers in Immunology
T cell receptor (TCR) binding to cognate antigen on the plasma membrane of an antigen-presenting cell (APC) triggers the immune synapse (IS) formation. The IS constitutes a dedicated contact region between different cells that comprises a signaling platform where several cues evoked by TCR and accessory molecules are integrated, ultimately leading to ...

Isolation and primary cultures of human intrahepatic bile ductular epithelium [PDF]

, 1988
A technique for the isolation of human intrahepatic bile ductular epithelium, and the establishment of primary cultures using a serum- and growth-factor-supplemented medium combined with a connective tissue substrata is described.
