A genome-wide CRISPR/Cas9 screen to identify phagocytosis modulators in monocytic THP-1 cells

open access: yesScientific Reports, 2021
Phagocytosis of microbial pathogens, dying or dead cells, and cell debris is essential to maintain tissue homeostasis. Impairment of these processes is associated with autoimmunity, developmental defects and toxic protein accumulation.

Complement Receptor-Mediated Phagocytosis Induces Proinflammatory Cytokine Production in Murine Macrophages

open access: yesFrontiers in Immunology, 2020
Macrophages are professional phagocytes that are uniquely situated between the innate and adaptive arms of immunity with a high capacity for phagocytosis and proinflammatory cytokine production as well as antigen presentation.

Impaired clearance of early apoptotic cells mediated by inhibitory IgG antibodies in patients with primary Sjögren's syndrome. [PDF]

open access: yesPLoS ONE, 2014
OBJECTIVES: Deficient efferocytosis (i.e. phagocytic clearance of apoptotic cells) has been frequently reported in systemic lupus erythematosus (SLE).

Phagocytosis is a primary determinant of pulmonary clearance of clinical Klebsiella pneumoniae isolates

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
IntroductionKlebsiella pneumoniae (Kp) is a common cause of hospital-acquired pneumonia. Although previous studies have suggested that evasion of phagocytic uptake is a virulence determinant of Kp, few studies have examined phagocytosis sensitivity in ...

Phosphoinositides and phagocytosis [PDF]

open access: yesThe Journal of Cell Biology, 2001
Phosphoinositide 3 kinases (PI3Ks)**Abbreviation used in this paper: PI3K, phosphoinositide 3 kinase. are known as regulators of phagocytosis. Recent results demonstrate that class I and III PI3Ks act consecutively in phagosome formation and maturation, and that their respective products, phosphatidylinositol 3,4,5-trisphosphate (PI[3,4,5]P3) and ...

Phagocytosis of microparticles increases responsiveness of macrophage-like cell lines U937 and THP-1 to bacterial lipopolysaccharide and lipopeptide

open access: yesScientific Reports, 2021
Following bacterial infection, macrophages produce pro-inflammatory cytokines in response to bacterial cell components, including lipopolysaccharide (LPS) and lipopeptide, and simultaneously phagocytize and digest the invading bacteria.

Microglia Actively Remodel Adult Hippocampal Neurogenesis through the Phagocytosis Secretome

open access: yesJournal of Neuroscience, 2020
During adult hippocampal neurogenesis, most newborn cells undergo apoptosis and are rapidly phagocytosed by resident microglia to prevent the spillover of intracellular contents. Here, we propose that phagocytosis is not merely passive corpse removal but

The Phagocytic Code Regulating Phagocytosis of Mammalian Cells

open access: yesFrontiers in Immunology, 2021
Mammalian phagocytes can phagocytose (i.e. eat) other mammalian cells in the body if they display certain signals, and this phagocytosis plays fundamental roles in development, cell turnover, tissue homeostasis and disease prevention.

Decreased neutrophil bactericidal activity during phagocytosis of a slime-producing Staphylococcus aureus strain. [PDF]

open access: yes, 2000
Phagocytosis and intracellular killing by bovine polymorphonuclear leukocytes (PMN) are important host defence mechanisms against mastitis caused by Staphylococcus aureus. We compared the phagocytosis and overall killing of a non slime-producing (NSP) S.

Phagocytosis in Teleosts. Implications of the New Cells Involved

open access: yesBiology, 2015
Phagocytosis is the process by which cells engulf some solid particles to form internal vesicles known as phagosomes. Phagocytosis is in fact a specific form of endocytosis involving the vesicular interiorization of particles. Phagocytosis is essentially
