Antibody-Based Strategies to Prevent and Treat Influenza

Frontiers in Immunology, 2015
Passive immunization using antibodies has been suggested to offer several benefits in comparison to other antiviral treatment options. The potential for seasonal protection arising from a single injection of antibodies is appealing and has been pursued ...

Trends of influenza B during the 2010–2016 seasons in 2 regions of north and south Italy: The impact of the vaccine mismatch on influenza immunisation strategy [PDF]

, 2018
Influenza A and B viruses are responsible for respiratory infections, representing globally seasonal threats to human health. The 2 viral types often co-circulate and influenza B plays an important role in the spread of infection.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Rescue of a H3N2 influenza virus containing a deficient neuraminidase protein by a hemagglutinin with a low receptor-binding affinity.

PLoS ONE, 2012
Influenza viruses possess at their surface two glycoproteins, the hemagglutinin and the neuraminidase, of which the antagonistic functions have to be well balanced for the virus to grow efficiently. Ferraris et al.

Cytomegalovirus is associated with depression and anxiety in older adults [PDF]

, 2008
Infection with cytomegalovirus (CMV), a β-herpesvirus, is common within the population. Although asymptomatic, infection is associated with increased serum concentrations of cytokines such as TNFα and IL-6, which are also related to mood and wellbeing ...

Random Mutagenesis in Porphyromonas gingivalis Enables Isolation of Mutants With Enhanced Secreted Protease Activity

Molecular Oral Microbiology, EarlyView.
ABSTRACT Porphyromonas gingivalis is a key pathogen in periodontitis, with secreted proteases as major virulence factors. We developed a screening method to generate and identify P. gingivalis mutants with elevated protease activity. Mutations were induced using the mutagens 2,6‐diaminopurine (2,6‐DAP) or ethyl methanesulfonate (EMS), and the ...

Hypoxic and Fe‐Responses are Regulated by the ERFVII Factors and the PCO Branch of the N‐Degron Pathway According to Iron Availability

Plant, Cell &Environment, EarlyView.
ABSTRACT In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe‐requiring enzymes catalyze reactions that also involve O2 as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe‐dependent enzymes Plant cysteine oxidases.

Antibody 27F3 Broadly Targets Influenza A Group 1 and 2 Hemagglutinins through a Further Variation in VH1-69 Antibody Orientation on the HA Stem

Cell Reports, 2017
Antibodies that target both group 1 and group 2 influenza A viruses are valuable for therapeutic and vaccine development, but only a few have been reported to date.

In vitro release of lectins by Phallusia mamillata hemocytes [PDF]

, 1991
α-Lactose specific lectins are released from Phallusia mamillata hemocytes during short-term cultures. The molecular weight of the subunits, the immunological cross-reaction and the sugar specificity suggest that the released lectins are similar to those

Competitive Elution of Pertussis Hemagglutinin

Experimental Biology and Medicine, 1950
SummaryThe hemagglutinating factor of Hemophilus pertussis culture supernatants can apparently be eluted from human erythrocytes by suspending such erythrocytes in a distilled-water extract of frozen and thawed red cells. Following the removal of the H. pertussis factor from agglutinated cells, these cells can be re-agglutinated by addition of fresh H.
