Complement System: An Immunotherapy Target in Colorectal Cancer

open access: yesFrontiers in Immunology, 2022
Colorectal cancer (CRC) is the third most common malignant tumor and the second most fatal cancer worldwide. Several parts of the immune system contribute to fighting cancer including the innate complement system.

CR2 Complement Receptor

open access: yesJournal of Investigative Dermatology, 1990
CR2, a membrane glycoprotein, is one of a number of cell-surface proteins which bind activation and processing fragments of the complement system. CR2, which is found on normal B lymphocytes, follicular dendritic cells in lymphoid organs, and epithelial cells, interacts preferentially with C3dg, the terminal activation/processing fragment of the third ...

Properdin Modulates Complement Component Production in Stressed Human Primary Retinal Pigment Epithelium Cells

open access: yesAntioxidants, 2020
The retinal pigment epithelium (RPE) maintains visual function and preserves structural integrity of the retina. Chronic dysfunction of the RPE is associated with retinal degeneration, including age-related macular degeneration (AMD).

Complement 1q/Tumor Necrosis Factor-Related Proteins (CTRPs): Structure, Receptors and Signaling

open access: yesBiomedicines, 2023
Adiponectin and the other 15 members of the complement 1q (C1q)/tumor necrosis factor (TNF)-related protein (CTRP) family are secreted proteins composed of an N-terminal variable domain followed by a stalk region and a characteristic C-terminal ...

Neuropilin-1 Acts as a Receptor for Complement Split Products

open access: yesFrontiers in Immunology, 2019
Complement split products (CSPs), such as the fragments C4d and C3d, which are generated as a consequence of complement regulatory processes, are established markers for disease activity in autoimmunity or antibody-mediated graft rejection.

Complement Plays a Critical Role in Inflammation-Induced Immunoprophylaxis Failure in Mice

open access: yesFrontiers in Immunology, 2021
Complement impacts innate and adaptive immunity. Using a model in which the human KEL glycoprotein is expressed on murine red blood cells (RBCs), we have shown that polyclonal immunoprophylaxis (KELIg) prevents alloimmunization to transfused RBCs when a ...

Complement Proteins as Soluble Pattern Recognition Receptors for Pathogenic Viruses

open access: yesViruses, 2021
The complement system represents a crucial part of innate immunity. It contains a diverse range of soluble activators, membrane-bound receptors, and regulators.

Staphylococcus aureus proteins Sbi and Efb recruit human plasmin to degrade complement C3 and C3b [PDF]

open access: yes, 2012
Upon host infection, the human pathogenic microbe Staphylococcus aureus (S. aureus) immediately faces innate immune reactions such as the activated complement system. Here, a novel innate immune evasion strategy of S. aureus is described.

New insights for C5a and C5a receptors in sepsis

open access: yesFrontiers in Immunology, 2012
The complement system plays a central role in inflammation and immunity. Among the complement activation products, C5a is one of the most potent inflammatory peptides with a broad spectrum of functions.

Phagocytosis of aged human neutrophils by macrophages is mediated by a novel "charge-sensitive" recognition mechanism [PDF]

open access: yes, 1989
The removal of neutrophils and their histotoxic contents from the inflamed site is a prerequisite for resolution of tissue injury, and a point at which factors critical to the pathogenesis of chronic inflammation may act.
