Calreticulin and Galectin-3 Opsonise Bacteria for Phagocytosis by Microglia

Frontiers in Immunology, 2019
Opsonins are soluble, extracellular proteins, released by activated immune cells, and when bound to a target cell, can induce phagocytes to phagocytose the target cell. There are three known classes of opsonin: antibodies, complement factors and secreted

Modulation of polarization and opsonin-independent phagocytosis in cultured human macrophages by Preimplantation Factor (PIF)

, 2023
Macrophages are the sentinels for the immune response by particle and pathogen ingestion, degradation, phenotypes alteration, and peptide presentation to T lymphocytes.

A Peptide-Fc Opsonin with Pan-Amyloid Reactivity

Frontiers in Immunology, 2017
There is a continuing need for therapeutic interventions for patients with the protein misfolding disorders that result in systemic amyloidosis. Recently, specific antibodies have been employed to treat AL amyloidosis by opsonizing tissue amyloid ...

Phylogenetic lineage and pilus protein Spb1/SAN1518 affect opsonin-independent phagocytosis and intracellular survival of Group B Streptococcus [PDF]

, 2011
Opsonin-independent phagocytosis of Group B Streptococcus (GBS) is important in defense against neonatal GBS infections. A recent study indicated a role for GBS pilus in macrophage phagocytosis (Maisey et al Faseb J 22 2008 1715-24).

Protection from Lethal Gram-Positive Infection by Macrophage Scavenger Receptor–Dependent Phagocytosis [PDF]

, 2000
Infections with gram-positive bacteria are a major cause of morbidity and mortality in humans. Opsonin-dependent phagocytosis plays a major role in protection against and recovery from gram-positive infections.

Moraxella catarrhalis evades neutrophil oxidative stress responses providing a safer niche for nontypeable Haemophilus influenzae

iScience, 2022
Summary: Moraxella catarrhalis and nontypeable Haemophilus influenzae (NTHi) are pathogenic bacteria frequently associated with exacerbation of chronic obstructive pulmonary disease (COPD), whose hallmark is inflammatory oxidative stress.

The Long Pentraxin PTX3 Is an Endogenous Inhibitor of Hyperoxaluria-Related Nephrocalcinosis and Chronic Kidney Disease

Frontiers in Immunology, 2018
The long pentraxin 3 (PTX3) exerts a variety of regulatory functions in acute and chronic tissue inflammation. In particular, PTX3 acts as an opsonin for a variety of pathogens and endogenous particles.

Evaluation of a Multivalent Artificial Opsonin to Target and Phagocytose Gram-Negative Bacteria [PDF]

, 2020
Thesis (Master's)--University of Washington, 2020Hospital-acquired infections (HAIs) are a significant medical concern that must be tackled. HAIs cost the United States billions of dollars annually, and in 2002, were the sixth-leading cause of death [1-2]
