Biomimetic carbon nanopolymers ANM-NPs act on mannose receptors and complement receptors to promote tumor antigen presentation [PDF]

Journal for ImmunoTherapy of Cancer
Background Enhancing immunogenicity and antigen-presentation efficiency is critical for tumor vaccine development. While yeast-surface glycoprotein side chains can improve antigen presentation, their ability to deliver tumor antigens remains limited ...

The Complement Receptors C3aR and C5aR Are a New Class of Immune Checkpoint Receptor in Cancer Immunotherapy [PDF]

Frontiers in Immunology, 2019
Cancer immunotherapy has made remarkable clinical advances in recent years. Antibodies targeting the immune checkpoint receptors PD-1 and CTLA-4 and adoptive cell therapy (ACT) based on ex vivo expanded peripheral CTLs, tumor infiltrating lymphocytes ...

Phagocytosis of Legionella pneumophila is mediated by human monocyte complement receptors. [PDF]

Journal of Experimental Medicine, 1987
We have examined receptors mediating phagocytosis of the intracellular bacterial pathogen, Legionella pneumophila. Three mAbs against the type 3 complement receptor (CR3), which recognizes C3bi, inhibit adherence of L.

Blood Transcriptome Analysis of Septic Patients Reveals a Long Non-Coding Alu-RNA in the Complement C5a Receptor 1 Gene

Non-Coding RNA, 2022
Many severe inflammation conditions are complement-dependent with the complement component C5a-C5aR1 axis as an important driver. At the RNA level, the blood transcriptome undergoes programmed expression of coding and long non-coding RNAs to combat ...

Neutrophils Require Activation to Express Functional Cell-Surface Complement Receptor Immunoglobulin

Frontiers in Immunology, 2022
The phagocytosis-promoting complement receptor, Complement Receptor Immunoglobulin (CRIg), is exclusively expressed on macrophages. It has been demonstrated that expression in macrophages could be modulated by inflammatory mediators, including cytokines.

Receptor-Mediated NETosis on Neutrophils

Frontiers in Immunology, 2021
Neutrophil extracellular traps (NETs), a web-like structures containing chromatin, have a significant role in assisting the capture and killing of microorganisms by neutrophils during infection.

Helix 8 in chemotactic receptors of the complement system.

PLoS Computational Biology, 2022
Host response to infection involves the activation of the complement system leading to the production of anaphylatoxins C3a and C5a. Complement factor C5a exerts its effect through the activation of C5aR1, chemotactic receptor 1, and triggers the G ...

The Role of Complement in the Mechanism of Action of Therapeutic Anti-Cancer mAbs

Antibodies, 2020
Unconjugated anti-cancer IgG1 monoclonal antibodies (mAbs) activate antibody-dependent cellular cytotoxicity (ADCC) by natural killer (NK) cells and antibody-dependent cellular phagocytosis (ADCP) by macrophages, and these activities are thought to be ...

Amyloid-β1-42 oligomers enhance mGlu5R-dependent synaptic weakening via NMDAR activation and complement C5aR1 signaling

iScience, 2023
Summary: Synaptic weakening and loss are well-correlated with the pathology of Alzheimer’s disease (AD). Oligomeric amyloid beta (oAβ) is considered a major synaptotoxic trigger for AD.
