Complement Evasion: An Effective Strategy That Parasites Utilize to Survive in the Host

Frontiers in Microbiology, 2019
Parasitic infections induce host immune responses that eliminate the invading parasites. However, parasites have evolved to develop many strategies to evade host immune attacks and survive in a hostile environment. The complement system acts as the first

Structure-Guided Engineering of a Complement Component C3-Binding Nanobody Improves Specificity and Adds Cofactor Activity

Frontiers in Immunology, 2022
The complement system is a part of the innate immune system, where it labels intruding pathogens as well as dying host cells for clearance. If complement regulation is compromised, the system may contribute to pathogenesis.

A novel trifunctional IgG-like bispecific antibody to inhibit HIV-1 infection and enhance lysis of HIV by targeting activation of complement [PDF]

, 2010
BACKGROUND: The complement system is not only a key component of innate immunity but also provides a first line of defense against invading pathogens, especially for viral pathogens.

Tah1 helix-swap dimerization prevents mixed Hsp90 co-chaperone complexes [PDF]

, 2015
Specific co-chaperone adaptors facilitate the recruitment of client proteins to the Hsp90 system. Tah1 binds the C-terminal conserved MEEVD motif of Hsp90, thus linking an eclectic set of client proteins to the R2TP complex for their assembly and ...

Biosynthetic homeostasis and resilience of the complement system in health and infectious diseaseResearch in context

EBioMedicine, 2019
Background: The complement system is a central component of the innate immune system. Constitutive biosynthesis of complement proteins is essential for homeostasis.

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.

Factor H Family Proteins in Complement Evasion of Microorganisms

Frontiers in Immunology, 2017
Human-pathogenic microbes possess various means to avoid destruction by our immune system. These include interactions with the host complement system that may facilitate pathogen entry into cells and tissues, expression of molecules that defuse the ...

Complementing antibody profiles: Assessing antibody function on antigen microarrays [PDF]

, 2012
Antibody effector functions other than neutralization depend on interactions with soluble and cellular components of the immune system. Antigen recognition is usually oligoclonal, with the different clones of antibodies belonging to different ...

Hijacking Complement Regulatory Proteins for Bacterial Immune Evasion

Frontiers in Microbiology, 2016
The human complement system plays an important role in the defense against invading pathogens, inflammation and homeostasis. Invading microbes, such as bacteria, directly activate the complement system resulting in the formation of chemoattractants and ...

Implications of Complement Imbalance in COVID-19: A Molecular Mechanistic Discussion on the Importance of Complement Balance [PDF]

Iranian Journal of Immunology, 2023
Two central questions in COVID-19 treatment which should be considered are: “How does the imbalance of the complement system affect the therapeutic approaches?” and “Do we consider complement inhibitors in therapeutic protocols?”.
