#Immune cell binding nanoparticle could lead to new sepsis treatment A nanoparticle that binds to immune cells in the body has been shown to tune down inflammation and offer a potential first-of-a-kind treatment for sepsis.
Sepsis is the single most frequent cause of death in hospitalised patients, causing 8 million deaths each year.
Supportive care is given, underlying infections treated, but there is no effective treatment. Researchers sprinkled a plastic nanoparticle with sialic acid ligands that modulated macrophage immune cells.
This produced a therapeutic response in mouse models of sepsis, in human lung cells and an ex vivo human lung model.
Sepsis occurs when chemicals released into the bloodstream to fight an infection trigger an inflammatory cascade that can damage organs. e saw increased survival in mice

Cutting off the cycle of inflammation could allow sepsis but also a frequent complication called ARDS to be treated.
Up to 25%of patients with severe sepsis develop ARDS and up to half of these patients will die.

#Researchers Discover Key Mechanism To Emergence Of Deadly Strep Bacteria The incidence of serious strep infections has risen dramatically in the last three decades,

Strep is estimated to cause over 700 million infections each year; over 650,000 of these are dangerous invasive forms.
They observed that during the early stages of a simple skin infection, a small subpopulation of the strep bacteria hijack a protein called plasminogen from the human bloodstream.

#Preventing dental implant infections One million dental implants are inserted every year in Germany, and often they need to be replaced due to issues such as tissue infections caused by bacteria.
In the future, these infections will be prevented thanks to a new plasma implant coating that kills pathogens using silver ions.
Bacterial infection of a dental implant is dreaded a complication, as it carries with it a high risk of jawbone degeneration.
Implanting an artificial dental root sets off a race between infectious pathogens and the body's own cellular defenses.
To lower the risk of infection and improve the long-term effectiveness of the implant, researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Bremen have developed a new type of implant coating in cooperation with industry partners.
