Immune complexes in chronic Chagas disease patients are formed by exovesicles from Trypanosoma cruzi carrying the conserved MASP N-terminal region [PDF]

, 2017
The exovesicles (EVs) are involved in pathologic host-parasite immune associations and have been recently used as biomarkers for diagnosis of infectious diseases.

Loss of very-long O-antigen chains optimizes capsule-mediated immune evasion by Salmonella enterica serovar Typhi. [PDF]

, 2013
UnlabelledExpression of capsular polysaccharides is a variable trait often associated with more-virulent forms of a bacterial species. For example, typhoid fever is caused by the capsulated Salmonella enterica serovar Typhi, while nontyphoidal Salmonella

Evasion Mechanisms Used by Pathogens to Escape the Lectin Complement Pathway

Frontiers in Microbiology, 2017
The complement system is a crucial defensive network that protects the host against invading pathogens. It is part of the innate immune system and can be initiated via three pathways: the lectin, classical and alternative activation pathway.

Dendrimer end-terminal motif-dependent evasion of human complement and complement activation through IgM hitchhiking

Nature Communications, 2021
Understanding nanomaterials interactions with complement is important for a number of applications. Here, the authors study the interaction of sub 6 nm dendrimers with complement and show the small dendrimers escape complement activation but do interact ...

Human Properdin Released By Infiltrating Neutrophils Can Modulate Influenza A Virus Infection

Frontiers in Immunology, 2021
The complement system is designed to recognise and eliminate invading pathogens via activation of classical, alternative and lectin pathways. Human properdin stabilises the alternative pathway C3 convertase, resulting in an amplification loop that leads ...

Hide and seek: how Lyme disease spirochetes overcome complement attack

Frontiers in Immunology, 2016
Overcoming the first line of the innate immune system is a general hallmark of pathogenic microbes to avoid recognition and to enter the human host.

African Trypanosomes undermine humoral responses and vaccine development : link with inflammatory responses? [PDF]

, 2017
African trypanosomosis is a debilitating disease of great medical and socioeconomical importance. It is caused by strictly extracellular protozoan parasites capable of infecting all vertebrate classes including human, livestock, and game animals.

Human complement control and complement evasion by pathogenic microbes – Tipping the balance [PDF]

Molecular Immunology, 2013
Complement is a central homeotic system of mammals and represents the first defense line of innate immunity. The human complement system is aimed to maintain homeostasis by recognizing and removing damaged or modified self material, as well as infectious foreign microbes.

Porphyromonas gingivalis periodontal infection and its putative links with Alzheimer’s disease [PDF]

, 2015
Periodontal disease (PD) and Alzheimer’s disease (AD) are inflammatory conditions affecting the global adult population. In the pathogenesis of PD, subgingival complex bacterial biofilm induces inflammation that leads to connective tissue degradation and
