Complement Receptors and Their Role in Leukocyte Recruitment and Phagocytosis
Frontiers in Cell and Developmental Biology, 2021 The complement system is deeply embedded in our physiology and immunity. Complement activation generates a multitude of molecules that converge simultaneously on the opsonization of a target for phagocytosis and activation of the immune system via ...

Structural Immunology of Complement Receptors 3 and 4
Frontiers in Immunology, 2018 Complement receptors (CR) 3 and 4 belong to the family of beta-2 (CD18) integrins. CR3 and CR4 are often co-expressed in the myeloid subsets of leukocytes, but they are also found in NK cells and activated T and B lymphocytes.

Complement Receptors in Inflammation [PDF]
, 2012 Complement was first discovered in 1889 as a bactericidal protein, distinct from heat stable antibodies present in normal serum. Since that time, it has been shown that the complement system is a biochemical cascade, comprised of more than 30 fluid phase and membraneassociated proteins, normally present as inactive forms.

Role of the complement system in the tumor microenvironment
Cancer Cell International, 2019 The complement system has traditionally been considered a component of innate immunity against invading pathogens and “nonself” cells. Recent studies have demonstrated the immunoregulatory functions of complement activation in the tumor microenvironment (

Complement Evasion Strategies of Viruses: An Overview
Frontiers in Microbiology, 2017 Being a major first line of immune defense, the complement system keeps a constant vigil against viruses. Its ability to recognize large panoply of viruses and virus-infected cells, and trigger the effector pathways, results in neutralization of viruses ...

An Immunoregulatory Role for Complement Receptors in Murine Models of Breast Cancer
Antibodies, 2021 The complement system has demonstrated roles in regulating tumor growth, although these may differ between tumor types. The current study used two murine breast cancer models (EMT6 and 4T1) to investigate whether pharmacological targeting of receptors ...

Mathematical Characterization of Private and Public Immune Repertoire Sequences [PDF]
Bull Math Biol 85, 102 (2023), 2022 Diverse T and B cell repertoires play an important role in mounting effective immune responses against a wide range of pathogens and malignant cells. The number of unique T and B cell clones is characterized by T and B cell receptors (TCRs and BCRs), respectively.
