Target shape dependence in a simple model of receptor-mediated endocytosis and phagocytosis [PDF]

Proc Natl Acad Sci USA 113(22):6113-6118 (2016), 2016
Phagocytosis and receptor-mediated endocytosis are vitally important particle uptake mechanisms in many cell types, ranging from single-cell organisms to immune cells. In both processes, engulfment by the cell depends critically on both particle shape and orientation.

Phagocytosis: Our Current Understanding of a Universal Biological Process

Frontiers in Immunology, 2020
Phagocytosis is a cellular process for ingesting and eliminating particles larger than 0.5 μm in diameter, including microorganisms, foreign substances, and apoptotic cells.

The zipper mechanism in phagocytosis: energetic requirements and variability in phagocytic cup shape [PDF]

arXiv, 2010
Phagocytosis is the fundamental cellular process by which eukaryotic cells bind and engulf particles by their cell membrane. Particle engulfment involves particle recognition by cell-surface receptors, signaling and remodeling of the actin cytoskeleton to guide the membrane around the particle in a zipper-like fashion. Despite the signaling complexity,

Phagocytosis in the Brain: Homeostasis and Disease

Frontiers in Immunology, 2019
Microglia are resident macrophages of the central nervous system and significantly contribute to overall brain function by participating in phagocytosis during development, homeostasis, and diseased states.

SeV C Protein Plays a Role in Restricting Macrophage Phagocytosis by Limiting the Generation of Intracellular Double-Stranded RNA

Frontiers in Microbiology, 2022
Macrophages play a central role in the innate immune response to respiratory viral infections through pro-inflammatory factor secretion and phagocytosis.

Microglial phagocytosis of neurons in neurodegeneration, and its regulation

Journal of Neurochemistry, 2021
There is growing evidence that excessive microglial phagocytosis of neurons and synapses contributes to multiple brain pathologies. RNA‐seq and genome‐wide association (GWAS) studies have linked multiple phagocytic genes to neurodegenerative diseases ...

Regulators of phagocytosis as pharmacologic targets for stroke treatment

Frontiers in Pharmacology, 2023
Stroke, including ischemic and hemorrhagic stroke, causes massive cell death in the brain, which is followed by secondary inflammatory injury initiated by disease-associated molecular patterns released from dead cells. Phagocytosis, a cellular process of

Coxiella burnetii Phagocytosis Is Regulated by GTPases of the Rho Family and the RhoA Effectors mDia1 and ROCK [PDF]

, 2015
The GTPases belonging to the Rho family control the actin cytoskeleton rearrangements needed for particle internalization during phagocytosis. ROCK and mDia1 are downstream effectors of RhoA, a GTPase involved in that process.

In vitro analysis of anti-HPA-1a dependent platelet phagocytosis and its inhibition using a new whole blood phagocytosis assay (WHOPPA)

Frontiers in Immunology, 2023
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a serious bleeding condition mostly caused by the reaction between maternal anti-HPA-1a antibodies and fetal platelets. This reaction leads to Fc-dependent platelet phagocytosis.
