Phagocytosis of large (but not small) particles requires PI 3-kinase activity. Here, Schlam et al. show that Rho GTPase-activating proteins are recruited to the phagocytic cup by products of PI 3 ...

In particular, TREM2-deficient microglia poorly polymerize actin, and phagocytosis requires more actin polymerization than does digestive exophagy, Sole-Domenech told Alzforum. “It is therefore ...

Research led by scientists from the Institute of Molecular Biology of Barcelona (IBMB) of the CSIC and the Bellvitge ...

The actin cytoskeleton provides force for dynamic cellular processes, such as motility, morphogenesis, cell division, endocytosis, and phagocytosis. The organization and dynamics of actin filaments ...

The actin cytoskeleton is essential for maintaining the shape and structure of cells, ... organelle transport and phagocytosis. Since actin is so essential to cellular function, ...

LIVE Webinar. Tuesday, October 5, 2021 11:00 AM - 12:00 PM Eastern Time. Enroll Now. Phagocytosis is a key mechanism for removing apoptotic cells and intruders. While this process is essential to ...

Shape Matters To Macrophages: Phagocytosis Depends More On Particle Shape Than Size. ScienceDaily . Retrieved June 4, 2025 from www.sciencedaily.com / releases / 2006 / 03 / 060322183627.htm ...

In the present study another aspect of metabolism during phagocytosis was examined — namely, the synthesis of cellular lecithin from 32 P-labeled lysolecithin complexed to albumin in the medium.

Researchers have filmed how epithelial cells in early embryos ingest and destroy bacteria, defending the embryo from infection.

Researchers have created a computational model capable of predicting whether or not organisms have the ability to 'eat' other cells through a process known as phagocytosis. The model may be a ...

The actin cytoskeleton plays a central role in multiple biological processes including muscle contraction, cell motility, cell division, endocytosis, and phagocytosis. The group is part of Finnish ...
