Travelling between Two Worlds: Complement as a Gatekeeper for an Expanded Host Range of Lyme Disease Spirochetes

open access: yesVeterinary Sciences, 2016
Evading innate immunity is a prerequisite for pathogenic microorganisms in order to survive in their respective hosts. Concerning Lyme disease spirochetes belonging to the Borrelia (B.) burgdorferi sensu lato group, a broad range of diverse vertebrates ...

Phosphocholine-Modified Lipooligosaccharides of Haemophilus influenzae Inhibit ATP-Induced IL-1beta Release by Pulmonary Epithelial Cells [PDF]

open access: yes, 2018
Phosphocholine-modified bacterial cell wall components are virulence factors enabling immune evasion and permanent colonization of the mammalian host, by mechanisms that are poorly understood.

Staphylococcus pseudintermedius Sbi paralogs inhibit complement and bind IgM, IgG Fc and Fab.

open access: yesPLoS ONE, 2019
The success of staphylococci as pathogens has been attributed, in part, to their ability to evade their hosts' immune systems. Although the proteins involved in evasion have been extensively studied in staphylococci affecting humans little ...

Sequence variations and protein expression levels of the two immune evasion proteins Gpm1 and Pra1 influence virulence of clinical Candida albicans isolates. [PDF]

open access: yesPLoS ONE, 2015
Candida albicans, the important human fungal pathogen uses multiple evasion strategies to control, modulate and inhibit host complement and innate immune attack. Clinical C.

Zika virus infection reprograms global transcription of host cells to allow sustained infection. [PDF]

open access: yes, 2017
Zika virus (ZIKV) is an emerging virus causally linked to neurological disorders, including congenital microcephaly and Guillain-Barré syndrome. There are currently no targeted therapies for ZIKV infection.

BBK32 attenuates antibody-dependent complement-mediated killing of infectious Borreliella burgdorferi isolates.

open access: yesPLoS Pathogens
Borreliella burgdorferi, the causative agent of Lyme disease, has evolved unique complement evasion proteins that promote its ability to establish and maintain infection in mammalian hosts. Among these is B.

Characteristics of Staphylococcus aureus infections to consider in designing an effective vaccine. [PDF]

open access: yes, 2010
_Staphylococcus aureus_ is a very versatile and adaptable microorganism. It can potentially infect virtually any host tissue. Given the appropriate conditions it can become a life-threatening pathogen, or a commensal colonizer of the nose.

Hepatitis C virus infection upregulates CD55 expression on the hepatocyte surface and promotes association with virus particles [PDF]

open access: yes, 2013
CD55 limits excessive complement activation on the host cell surface by accelerating the decay of C3 convertases. In this study, we observed that hepatitis C virus (HCV) infection of hepatocytes or HCV core protein expression in transfected hepatocytes ...

Competition between antagonistic complement factors for a single protein on N. meningitidis rules disease susceptibility

open access: yeseLife, 2014
Genome-wide association studies have found variation within the complement factor H gene family links to host susceptibility to meningococcal disease caused by infection with Neisseria meningitidis (Davila et al., 2010).

Identification of Plasmodium falciparum var1CSA and var2CSA domains that bind IgM natural antibodies [PDF]

open access: yes, 2006
Malaria in pregnancy is responsible for maternal anaemia, low-birth-weight babies and infant deaths. Plasmodium falciparum infected erythrocytes are thought to cause placental pathology by adhering to host receptors such as chondroitin sulphate A (CSA ...
