Opsonin-Independent Phagocytosis of Surface-Adherent Bacteria by Human Alveolar Macrophages

, 1984
Opsonin-independent mechanisms of phagocytosis may be important in host defense of certain body sites such as the lung, in this study, one such mechanism, “surface phagocytosis,” was investigated by measuring the uptake of unopsonized [3H]-labeled ...

Role of Mac-1 integrin in generation of extracellular vesicles with antibacterial capacity from neutrophilic granulocytes

Journal of Extracellular Vesicles, 2020
Production of extracellular vesicles (EVs) involved in intercellular communication is a common capacity of most cell types. Upon encountering opsonized microorganisms, neutrophilic granulocytes release EVs that compromise bacterial growth. We carried out

The Proteome of Plasma Extracellular Vesicles in Latent and Active Tuberculosis Reveals Phase‐Specific Composition and Immunometabolic Insights

FASEB BioAdvances, Volume 8, Issue 10, October 2026.
Plasma extracellular vesicles (EVs) from individuals with latent (LTB) or active tuberculosis (ATB) exhibit distinct proteomic compositions, reflecting the underlying immunometabolic states of each phase. In LTB, EVs are enriched in proteins associated with tissue remodeling and lipid metabolism, including TGFβ, APOA1, and APOE, which may participate ...

Humoral opsonin from the colonial ascidian Botryllus schlosseri as a member of the galectin family

, 2000
The synthesis and secretion of the humoral opsonin from the colonial ascidian Botryllus schlosseri was studied by using specific polyclonal antibodies that recognise both of the bands obtained after SDS-PAGE of the purified lectin.

CCN1 is an opsonin for bacterial clearance and a direct activator of Toll-like receptor signaling

Nature Communications, 2020
CCN1 is a matricellular protein with a variety of functions, including an effect on wound healing and an association with inflammation. Here, the authors identify a possible mechanism by showing that CCN1 mediates the clearance of bacterial infections in

A simple, ex vivo phagocytosis assay of Plasmodium vivax merozoites by flow cytometry

Memorias do Instituto Oswaldo Cruz
As phagocytosis is the first line of defense against malaria, we developed a phagocytosis assay with Plasmodium vivax (P. vivax) merozoites that can be applied to evaluate vaccine candidates. Briefly, after leukocyte removal with loosely packed cellulose

Bacterial Infections, DNA Virus Infections, and RNA Virus Infections Manifest Differently in Neutrophil Receptor Expression

The Scientific World Journal, 2012
Treating viral illnesses or noninfective causes of inflammation with antibiotics is ineffective and contributes to the development of antibiotic resistance, toxicity, and allergic reactions, leading to increasing medical costs.
