CEACAM3—A Prim(at)e Invention for Opsonin-Independent Phagocytosis of Bacteria

open access: yesFrontiers in Immunology, 2020
Phagocytosis is one of the key innate defense mechanisms executed by specialized cells in multicellular animals. Recent evidence suggests that a particular phagocytic receptor expressed by human polymorphonuclear granulocytes, the carcinoembryonic ...

Human Opsonins Induced during Meningococcal Disease Recognize Transferrin Binding Protein Complexes [PDF]

open access: yesInfection and Immunity, 1999
ABSTRACT Patient serum opsonins against transferrin binding protein A+B (TbpA+B) complexes from two Neisseria meningitidis strains (K454 and B16B6, with 85- and 68-kDa TbpB, respectively) were quantified by a functional phagocytosis and oxidative burst assay.

The adaptor molecule Nck localizes the WAVE complex to promote actin polymerization during CEACAM3-mediated phagocytosis of bacteria. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: CEACAM3 is a granulocyte receptor mediating the opsonin-independent recognition and phagocytosis of human-restricted CEACAM-binding bacteria.

Function of the lipopolysaccharide‐binding protein of Periplaneta americana as an opsonin

open access: yesFEBS Letters, 1992
Previously, we reported the purification of an LPS‐binding protein from the hemolymph of the American cockroach that was specific for E. coli LPS. In this study we found that this protein participated in the clearance of E. coil cells injected into the abdominal cavity of the cockroach, and that hemocytes ingested E.

Biological significance of C-reactive protein, the ancient acute phase functionary

open access: yesFrontiers in Immunology, 2023
C-reactive protein (CRP) is one of the major members of the family of acute phase proteins (APP). Interest in this CRP was the result of a seminal discovery of its pattern of response to pneumococcal infection in humans.

Characterization of the effects of cross-linking of macrophage CD44 associated with increased phagocytosis of apoptotic PMN.

open access: yesPLoS ONE, 2012
Control of macrophage capacity for apoptotic cell clearance by soluble mediators such as cytokines, prostaglandins and lipoxins, serum proteins, and glucocorticoids may critically determine the rate at which inflammation resolves.

Development and characterization of a prototypic pan-amyloid clearing agent – a novel murine peptide-immunoglobulin fusion

open access: yesFrontiers in Immunology, 2023
IntroductionSystemic amyloidosis is a progressive disorder characterized by the extracellular deposition of amyloid fibrils and accessory proteins in visceral organs and tissues.

C-type lectin in Chlamys farreri (CfLec-1) mediating immune recognition and opsonization. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: C-type lectins are a superfamily of Ca(2+) dependent carbohydrate-recognition proteins that play significant diverse roles in nonself-recognition and clearance of invaders.

Role of surface charge and oxidative stress in cytotoxicity of organic monolayer-coated silicon nanoparticles towards macrophage NR8383 cells [PDF]

open access: yes, 2010
Background - Surface charge and oxidative stress are often hypothesized to be important factors in cytotoxicity of nanoparticles. However, the role of these factors is not well understood.
