NewsHow microbes protect the lungs against allergies
A study has revealed that microbes protect the lungs from subsequently developing allergies and asthma. This long-term protection is “memorized” not by immune system cells but by fibroblasts, structural cells in the lungs.

NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsStudy warns of underrecognized Lassa Fever threat with global implications
A new study shows an urgent need for improved detection and treatment of Lassa fever. The study in Liberia found a high prevalence of Lassa fever among febrile admissions: 11% of patients with fever had Lassa fever despite not being suspected clinically.

NewsResearchers identify ‘neuroimmune signature’ that can predict viral hepatitis complications
A network of genes linked to the nervous and immune systems can predict cancer risk and even explain symptoms such as fatigue and depression resulting from viral hepatitis infection.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.

NewsNew tool reveals the secrets of HIV-infected cells
Scientists have developed a novel tool—named HIV-seq—for profiling the features of rare HIV-infected cells from people with HIV. Using the new tool, they’ve found key differences in people’s HIV-infected cells before versus after starting antiretroviral therapy.

NewsNanoparticle vaccine approach takes on a new target: Hepatitis C virus
Scientists have engineered a native-like, stabilized version of Hepatitis C virus’s E1E2 complex and used it to build a nanoparticle-based vaccine candidate. It uses a technology called self-assembling protein nanoparticles, which organizes copies of the proteins into virus-like clusters that the immune system can recognize.

NewsHuge toll: Bird flu rampant among black vultures
More than four out of every five dead black vultures examined by University of Georgia researchers tested positive for highly pathogenic avian influenza, according to a new study. Their indiscriminate scavenging appears to sustain transmission of the virus beyond the typical bird flu season.

News10 Years, 70% shift: Wastewater upgrades quietly transform river microbiomes
Researchers investigated how the upgrade of a WWTP influenced nitrogen-cycling microorganisms and DNA viruses in its receiving river. The research compared the river whose WWTP was upgraded during the study period against the river whose upgrade occurred prior to the study.

NewsScientists identify therapeutic target that would curb the spread of coronaviruses
Coronaviruses not only use the machinery of the human cells they infect: they modify it to achieve optimal conditions to produce viral proteins and thus spread more quickly, according to a study identifying enzymes that modify transfer RNAs as key elements for coronavirus infection.

NewsNew study demonstrates universal newborn cCMV screening leads to earlier detection and increased identification of mild hearing loss
A new retrospective cohort study examining the impact of Minnesota’s first-in-the-nation mandated universal newborn screening for congenital cytomegalovirus (cCMV) shows that universal screening significantly decreased the age at first audiology visit and increased identification of mild hearing loss in infants.

NewsEnhanced inner ear tropism of Adeno-Associated Virus (AAV) vectors via peptide display on AAV1 capsid
Researchers improving efficiacy of AAV)-mediated gene therapy for the inner ear screened and inserted short peptide motifs onto the surface of the AAV1 capsid. These engineered vectors achieved markedly higher transduction rates in inner ear hair cells and supporting cells.

NewsBiomarkers indicating higher liver cancer risk in chronic hepatitis B patients identified
Researchers have identified Hepatitis B RNA serum levels as a biomarker that more accurately stratifies risk of liver cancer in individuals who have been functionally cured of chronic hepatitis B.
-
NewsImaging technique is step towards needed treatments for hantaviruses in new molecular ma
Researchers have produced a detailed blueprint, the highest resolution yet, for a protein complex the Andes virus uses to infect host cells. The new detailed structural information enabled the researchers to produce a vaccine candidate that caused mice to produce neutralizing antibodies against the Andes virus.

NewsProtein interplay offers insights into how the immune system recognizes viral RNA
A new study reveals how two proteins cooperate in a key early step of antiviral detection. Using cryo-electron microscopy and high-speed atomic force microscopy, researchers found that LGP2 binds to viral RNA and recruits MDA5 molecules, as if threading beads on a string.

NewsScientists uncover mechanism used by three bacteria-killing viruses to target transporter
Biochemists have homed in on an underexplored small transporter called MurJ that is a vital part of the pathway bacteria use to build their chain-mail-like cell wall. Using advanced tools, the scientists have determined the common mechanism used by three different bacteria-killing viruses to block MurJ from doing its job.

NewsDiffering immune responses in infants may explain increased severity of RSV over SARS-CoV-2
Reseachers report that the two respiratory viruses trigger different immune responses. Those differences might explain why these two diseases have different clinical outcomes and require different treatment strategies.

NewsCOVID-19 infection predicts higher risk of kidney disease, study finds
Researchers have found that previous COVID-19 infection is a significant risk factor for kidney disease. Compared to influenza, those with a history of COVID-19 infection have a 2.3-times higher risk of acute kidney injury and a 1.4-times higher risk of chronic kidney disease, according to an analysis of over three million patients.

NewsHPV vaccination provides “sustained protection” against cervical cancer
Human papillomavirus (HPV) vaccination is associated with a significantly reduced risk of invasive cervical cancer, with no indication of waning protection up to 18 years after vaccination, finds a study.

NewsSingle daily pill shows promise as replacement for complex, multi-tablet HIV treatment regimens
A phase 3 clinical trial has shown that a new, daily oral tablet that combines two current HIV treatment medications – bictegravir and lenacapavir (BIC/LEN) – may simplify treatment significantly for people with HIV who currently take very complex treatments.
