Phagocytosis of Microorganisms

Clinical Infectious Diseases, 1982
For its survival, the host depends on an elaborate internal defense system to protect against persistent invasion by pathogenic microorganisms. This system is composed primarily of cellular and humoral components of the circulatory system and includes the "professional" phagocytes (polymorphonuclear leukocytes, monocytes, and tissue macrophages ...

HMGB1 Derived from the Pyroptotic Microenvironment Promotes Macrophage Extracellular Traps in Hirschsprung‐Associated Enterocolitis

Advanced Biology, EarlyView.
HMGB1 derived from the pyroptotic environment in Hirschsprung‐associated enterocolitis mediates the formation of macrophage extracellular traps through TLR4 ‐p38 MAPK/p65 NF‐kB signaling pathways. Macrophage extracellular traps induce increased ROS production and pyroptosis of colonic epithelial cells.

Lipoprotein(a), an Opsonin, Enhances the Phagocytosis of Nontypeable Haemophilus influenzae by Macrophages

Journal of Immunology Research, 2021
We recently showed that both nontypeable Haemophilus influenzae (NTHi) and its surface plasminogen- (Plg-) binding proteins interact with lipoprotein(a) (Lp(a)) in a lysine-dependent manner.

15-Epi-LXA4 and 17-epi-RvD1 restore TLR9-mediated impaired neutrophil phagocytosis and accelerate resolution of lung inflammation

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Timely resolution of bacterial infections critically depends on phagocytosis of invading pathogens by polymorphonuclear neutrophil granulocytes, followed by neutrophil apoptosis and removal by macrophages. Neutrophils integrate cues from the

Illuminating New Frontiers: Exploring the Photosensitizing Potential of Passiflora Species in Combating Methicillin‐Resistant Staphylococcus aureus (MRSA) and Their Infection in Senescent Mice

Advanced Biology, EarlyView.
This study investigates the photosensitizing potential of Passiflora cincinnata in Antimicrobial Photodynamic Therapy (aPDT) against skin infection caused by Methicillin‐resistant Staphylococcus aureus (MRSA) in a senescent murine model. The P. cincinnata exhibits antimicrobial activity, with reduced bacterial load, lower leukocyte infiltration, and ...

PGE2 inhibits neutrophil phagocytosis through the EP2R–cAMP–PTEN pathway

Immunity, Inflammation and Disease, 2022
Prostaglandin E2 (PGE2) is a potent lipid mediator of inflammation that modulates immune cell function by binding to unique G protein‐coupled receptors (EP receptors). PGE2 production increases during microbial infection and inflammation.

The origins of phagocytosis and eukaryogenesis [PDF]

Biology Direct, 2009
Abstract Background Phagocytosis, that is, engulfment of large particles by eukaryotic cells, is found in diverse organisms and is often thought to be central to the very origin of the eukaryotic cell, in particular, for the acquisition of bacterial endosymbionts including the ancestor of the mitochondrion.

Biomimetic Nanomedicines Deliver Naringin for Enhanced Acute Liver Failure Therapy via Balanced Regulation of Hepatocyte Oxidative Stress and Kupffer Cell Inflammation

Advanced Functional Materials, EarlyView.
A biomimetic nanomedicine (RBLN) constructed by loading natural antioxidants to clinically used layered double hydroxide nanoparticles is surface coated with fresh or senescent red blood cell membrane for balanced drug delivery to hepatocytes and KCs, thereby simultaneously alleviating liver oxidant stress and inflammation for effective drug‐induced ...

Modulation (Inhibition and Augmentation) of Complement Receptor-3-Mediated Myelin Phagocytosis

Neurobiology of Disease, 2001
The removal of damaged myelin is central to repair after injury to axons and in autoimmune demyelinating diseases. Complement receptor 3 (CR3/MAC-1) plays a major role in mediating the phagocytosis of damaged myelin by macrophages and microglia.
