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

Antioxidants, 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 Plays a Critical Role in Inflammation-Induced Immunoprophylaxis Failure in Mice

Frontiers 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 ...

CR2 Complement Receptor

Journal 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 ...

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

Biomedicines, 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 ...

C3‐dependent effector functions of complement

Immunological Reviews, 2022
C3 is the central effector molecule of the complement system, mediating its multiple functions through different binding sites and their corresponding receptors. We will introduce the C3 forms (native C3, C3 [H2O], and intracellular C3), the C3 fragments

Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. [PDF]

, 2018
Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined.

Preferential association of hepatitis C virus with CD19+ B cells is mediated by complement system [PDF]

, 2016
Extrahepatic disease manifestations are common in chronic hepatitis C virus (HCV) infection. The mechanism of HCV-related lymphoproliferative disorders is not fully understood.

Complement Proteins as Soluble Pattern Recognition Receptors for Pathogenic Viruses

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

Complement C2 Receptor Inhibitor Trispanning: A Novel Human Complement Inhibitory Receptor [PDF]

The Journal of Immunology, 2005
AbstractThe complement system presents a powerful defense against infection and is tightly regulated to prevent damage to self by functionally equivalent soluble and membrane regulators. We describe complement C2 receptor inhibitor trispanning (CRIT), a novel human complement regulatory receptor, expressed on hemopoietic cells and a wide range of ...

Menopause leads to elevated expression of macrophage-associated genes in the aging frontal cortex: rat and human studies identify strikingly similar changes. [PDF]

, 2012
BACKGROUND The intricate interactions between the immune, endocrine and central nervous systems shape the innate immune response of the brain. We have previously shown that estradiol suppresses expression of immune genes in the frontal cortex of ...
