Glycan repositioning of influenza hemagglutinin stem facilitates the elicitation of protective cross-group antibody responses.
(
Nature Research
, 2020 , Article)
The conserved hemagglutinin (HA) stem has been a focus of universal influenza vaccine efforts. Influenza A group 1 HA stem-nanoparticles have been demonstrated to confer heterosubtypic protection in animals; however, the ...
Immune Modulatory Effects of Vitamin D on Viral Infections.
(
MDPI
, 2020 , Article)
Viral infections have been a cause of mortality for several centuries and continue to endanger the lives of many, specifically of the younger population. Vitamin D has long been recognized as a crucial element to the ...
Prevalence and molecular profiling of Epstein Barr virus (EBV) among healthy blood donors from different nationalities in Qatar.
(
Public Library of Science
, 2017 , Article)
The Epstein-Barr virus (EBV) is the causative agent of infectious mononucleosis. EBV is highly prevalent lymphotropic herpesvirus and has been linked to several malignancies. Transmission is generally by oral secretions, ...
Viral-Induced Enhanced Disease Illness
(
Frontiers Media
, 2018 , Article)
Understanding immune responses to viral infections is crucial to progress in the quest for effective infection prevention and control. The host immunity involves various mechanisms to combat viral infections. Under certain ...

The present study is designed to compare demographic characteristics, plasma biochemistry, and the oral microbiome in obese (N = 37) and lean control (N = 36) subjects enrolled at Qatar Biobank, Qatar. Plasma hormones, ...
Prevalence of antibiotic resistant Escherichia coli isolates from fecal samples of food handlers in Qatar
(
BioMed Central
, 2018 , Article)
Background: It is well documented that food handlers harbor and shed enteric foodborne pathogens causing
foodborne disease outbreaks. However, little known on enteric antibiotic resistant (AR) bacteria carriage in ...
Activation Dynamics and Immunoglobulin Evolution of Pre-existing and Newly Generated Human Memory B cell Responses to Influenza Hemagglutinin.
(
Elsevier
, 2019 , Article)
Vaccine-induced memory B cell responses to evolving viruses like influenza A involve activation of pre-existing immunity and generation of new responses. To define the contribution of these two types of responses, we ...
Measuring influenza hemagglutinin (HA) stem-specific antibody-dependent cellular cytotoxicity (ADCC) in human sera using novel stabilized stem nanoparticle probes
(
Elsevier
, 2020 , Article)
Background: Generating vaccine that confers a complete protection is a major goal in designing a universal influenza vaccine. Currently, there is a considerable interest in the broadly neutralizing antibodies (bnAb) targeting ...
