NewsLong Covid lessons: New cell therapy boosts immune recovery in cats with severe coronavirus
Feline infectious peritonitis is a serious and historically fatal disease in cats caused by a coronavirus. Scientists have found that mesenchymal stromal cells, or MSC therapy, in combination with antiviral drugs, helped cats’ immune systems recover and reduced systemic inflammation.

NewsScientist’s cat on the hunt helps to discover a second new virus
Pepper, the pet cat who made headlines last year for his role in the discovery of the first jeilongvirus found in the U.S., is at it again. This time, his hunting prowess contributed to the identification of a new strain of orthoreovirus.

NewsAnti-cancer drug shows promise against tick-borne virus
Researchers have offered fresh insights into how Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV), an emerging tick-borne pathogen, opposes host apoptosis signaling.

NewsHepatitis C treatment is not reaching some at-risk populations, studies show
Studies reveal that two vulnerable populations — children and recently pregnant women — face disparities in access to treatment for hepatitis C infection. Without treatment, they are at risk of long-term adverse health outcomes such as cirrhosis, liver cancer and death.

NewsCohort data from Denmark show real-world evidence of stable protection against HPV-related cervical cancer
Denmark has been offering free vaccination against human papillomavirus (HPV) to girls since 2008. New data show vaccination has effectively reduced infections with cancerogenic HPV 16/18 types covered by the vaccine, indicating population immunity.

NewsScientists ID new drug target for treating cancer and viral infections
An international team of researchers has identified a molecular mechanism that regulates the activity of N-myristoyltransferases, enzymes that ensure the proteins’ function by chemically modifying them during their production.

NewsChameleon plant polysccharide targets acute pneumonia with H1N1 and MRSA coinfection
A new study discusses how an anti-complement homogeneous polysaccharide from Houttuynia cordata ameliorates acute pneumonia with H1N1 and MRSA coinfection through rectifying Treg/Th17 imbalance in the gut–lung axis and NLRP3 inflammasome activation.

NewsGlobal trends and cross-country inequalities of acute hepatitis E in the elderly, 1990–2021
Acute hepatitis E (AHE) in the elderly can lead to severe complications including liver failure and mortality. A new study aimed to assess the trends and health inequalities of AHE among the elderly over the past three decades, and predict its changes by 2030.

NewsStructure of tick-borne virus revealed at atomic resolution for the first time
One emerging tick-borne virus in North America is the Powassan virus (POWV), which can cause encephalitis, seizures, paralysis and coma. Rates of POWV infections have increased in recent years and currently, there are no treatments available.

NewsSummer travel ‘will increase the spread of measles,’ expert says
The number of measles cases in the U.S. has reached its highest point in 33 years, and outbreaks are expected to continue, especially amid national and international travel.

NewsFrom COVID to cancer, new at-home ‘coffee-ring’ test spots disease with startling accuracy
A new, low-cost biosensing technology could make rapid at-home tests up to 100 times more sensitive to viruses like COVID-19. The diagnostic could expand rapid screening to other life-threatening conditions like prostate cancer and sepsis as well.

NewsScientists investigate gut microbiota in elderly patients with acute hepatitis E infection
A new study of the impact of hepatitis E virus infection on the gut microbiota identifies a bacterial species as a potential biomarker for disease outcomes.
-
NewsVanderbilt and Parse Biosciences collaborate on new measles treatment
Vanderbilt University Medical Center and Parse Biosciences, an innovator in single-cell sequencing, are collaborating on a new treatment to help unvaccinated measles victims, as the U.S. measles outbreak has now reached its highest case count in 30 years.

NewsCancer-fighting herpes virus shown to be an effective treatment for some advanced melanoma
A genetically engineered herpes simplex virus, when combined with immunotherapy, reduces or eliminates tumors in one-third of clinical trial patients, according to a new study.
-
NewsTiny antibody has big impact on deadly viruses
Researchers have discovered a strategy to neutralise two lethal viruses for which there is currently no approved vaccine or cure. The team identified the first ever nanobody to work against Nipah and Hendra, henipaviruses which have jumped from animals to people.
