Microwaves used to deactivate coronavirus, flu, other aerosolized viruses
As the pandemic continues, scientists are increasingly focused on developing methods to assist in decontaminating surfaces and spaces. In Review of Scientific Instruments, researchers report on experimental tools capable of presenting electromagnetic waves to an aerosol mixture with the capability to vary power, energy, and frequency of the electromagnetic exposure. The researchers seek to better characterize the threshold levels of microwave energy needed to inactivate aerosolized viral particles and reduce their ability to spread infection. (2021-01-26)

Esophageal cancer patients show abundance of oral pathogens
DNA from various oral bacterial pathogens has been found in tumors from esophageal cancer patients. Researchers led by Tokyo Medical and Dental University (TMDU) examined bacterial pathogens in plaque and saliva from esophageal cancer patients, determining that a prevalence of three species in particular, along with alcohol consumption, is associated with a high risk of esophageal cancer. Screening of oral pathogens could therefore be used for early disease detection. (2021-01-14)

Infection biology: How one pathogen evades the immune system
A research team of Ludwig-Maximilians-Universitaet (LMU) in Munch led by Nicolai Siegel has uncovered a mechanism that enables the parasite that causes sleeping sickness in humans to escape the attention of the immune system.

The puzzle of nonhost resistance: why do pathogens harm some plants but not others?
There are many examples of plants that are susceptible to one pathogen but able to resist another closely related pathogen. By uncovering the mechanism behind resistance, we can obtain a deeper understanding of the plant immune system and can also uncover previously unknown aspects of immune signaling and regulation, which can help scientists improve resistance against a broader spectrum of pathogens.

COVID-19 highlights risks of wildlife trade
Many diseases, such as COVID-19, made the jump from animals to people with serious consequences for the human host. International researchers, including Göttingen University, say that more epidemics resulting from animal hosts are inevitable unless urgent action is taken. To protect against future pandemics, they call for governments to establish effective legislation addressing wildlife trade, protection of habitats and reduction of interaction between people, wildlife and livestock. Their review appeared in Trends in Ecology & Evolution. (2020-11-17)

How allergens trigger itching: Finding points to new targets for allergy drug development
A key step in the immune system's response to allergens has been uncovered by researchers at Massachusetts General Hospital. They have shown that a neuropeptide called Substance P is released by certain neurons in the skin when they detect allergens, and that this substance is essential in the development of allergen-induced immune responses. This research could lead to the development of new and better methods to treat and prevent allergies. (2020-10-29)

Biophysicists modelled the effect of antiseptics on bacterial membranes
A team of biophysics from leading Russian research and educational institutions (MSU, RUDN University, and the Federal Research and Clinical Center of the Federal Medical-Biological Agency of Russia) developed a computer model that shows the effect of antiseptics on bacterial membranes. The common concepts regarding the mode of action of antiseptics turned out to be incorrect: instead of destroying bacterial membranes, they cause changes in their structure. These changes make the bacteria weaker and more susceptible to adverse external factors. (2020-10-28)

Let's (not) stick together
New research led by the University of Pittsburgh's Swanson School of Engineering examines the properties of the mucus of cystic fibrosis (CF) patients and the role it plays in a pathogens' ability to survive. The new information could have important implications for CF treatment. (2020-10-28)

Multiple sclerosis as the flip side of immune fitness
About half of the people with multiple sclerosis have the HLA-DR15 gene variant. A study led by the University of Zurich has now shown how this genetic predisposition contributes to the development of the autoimmune disease multiple sclerosis in combination with environmental factors. The decisive factor is the shaping of a repertoire of immune cells which - although they are effective in fighting off pathogens such as Epstein-Barr virus - also attack brain tissue. (2020-10-22)
