NewsHIV discovery could open door to long-sought cure
Scientists have uncovered a key reason why HIV remains so difficult to cure: Their research shows that small changes in the virus affect how quickly or slowly it replicates, and how easily or stubbornly it can reawaken from hiding.

NewsNew diagnostic tool uses bioluminescence to detect viruses
Researchers are shining a powerful new light into the viral darkness with the development of Luminescence CAscade-based Sensor (LUCAS), a rapid, portable, highly-sensitive diagnostic tool for processing complex biological samples.

NewsResearchers engineer a herpes virus to turn on T cells for immunotherapy
Researchers have identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival - a promising tool in the fight against cancer.

NewsTrees vs. disease: Tree cover reduces mosquito-borne health risk
A new study shows that in Costa Rica, even modest patches of tree cover can reduce the presence of invasive mosquito species known to transmit diseases like dengue fever.

NewsClaudin-11 plays a pivotal role in the clathrin-mediated endocytosis of influenza A virus
In a new study, researchers investigated a key host factor that promotes influenza virus infection. They found that claudin-11, a four-transmembrane protein encoded by claudin-11, plays an integral part in influenza virus clathrin-mediated endocytosis.

NewsZika virus uses cells’ ‘self-care’ system to turn against host
A new study reveals the biological secret to the Zika virus’s infectious success: Zika uses host cells’ own ‘self-care’ system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place.

NewsPortable HIV monitoring device shows promise for remote settings
A newly developed microfluidic biosensor promises to reshape how CD4+ T cells — key indicators of immune function in Human Immunodeficiency Virus (HIV) patients — are detected.

NewsDisrupting the residual triggers of COVID-19 in patients with long COVID
Spatial transcriptomics reveals activation of SARS-CoV-2-related signaling pathways in the epipharynx of patients with long COVID.
-
NewsKIST develops multifunctional peptide that fights viruses and promotes wound healing
Researchers announced that they have developed a therapeutic substance with both antiviral and tissue regenerative properties, based on a peptide derived from natural sources.
-
NewsSARS-CoV-2 corrupts some white blood cells to suppress immune system, suggesting path to severe COVID
A study found that neutrophils may be altered by SARS-CoV-2, the virus that causes COVID-19, to cease their normal function of destroying pathogens in the body and, instead, significantly inhibit other immune cells critical for fighting the virus.
-
NewsDNA test detects three times more lung pathogens than traditional methods
A study on the application of Metagenomic next-generation sequencing (mNGS) found it can achieve early detection of pathogens and accelerate development of targeted anti-infection treatment plans, improving treatment outcomes and patient prognosis.

CareersHow structural imaging is revolutionising vaccines
Dr. Peijun Zhang, Director of the Electron Bio-Imaging Centre (eBIC) at the UK’s national synchrotron facility Diamond Light Source, reveals how Cryo-ET is powering some of the most important advances in vaccine research.
-
NewsEngineered bacteria can deliver antiviral therapies and vaccines
New research demonstrates how specially engineered bacteria taken orally can operate as a delivery system for antiviral therapies and vaccines.
-
NewsA gene variant increases the risk of long COVID
An international team of researchers has found a genetic link to long-term symptoms after COVID-19. The identified gene variant is located close to the FOXP4 gene, which is known to affect lung function.
-
NewsScientists uncover how certain cholera strains are so successful at evading phage attacks
A new study shows that a virulent lineage of cholera acquired multiple distinct bacterial immune systems that have protected it from diverse types of phages. This defense may have contributed to the massive scale of the Latin American epidemic.
-
NewsResearchers reveal remarkable antimicrobial activity in hydrogen boride nanosheets
Hydrogen boride (HB) nanosheets represent an exciting new frontier in the search for technologies that can combat microbes in everyday settings. Researchers discovered that they exhibit excellent antibacterial, antiviral, and antifungal properties.
-
NewsOrganoids reveal the secrets of bat immunity
Researchers successfully infected both bat organoids and human airway organoids with the Marburg virus. Compared to the human models, bat organoids exhibited a significantly higher baseline antiviral immune activity even before infection.

NewsCucumber green mottle mosaic virus breakthrough: uncovering novel antiviral strategy by hijacking host proteins
Researchers have made a groundbreaking discovery in their study of the Cucumber Green Mottle Mosaic Virus (CGMMV). CGMMV utilizes the host cytosolic fructose-1,6-bisphosphatase (FBPase) to catalyze the formation of BMCs via liquid-liquid phase separation (LLPS).

NewsCold sore viral infection implicated in development of Alzheimer’s disease
Symptomatic infection with the virus responsible for cold sores around the mouth–herpes simplex 1, or HSV-1 for short—may have a key role in the development of Alzheimer’s disease, suggests a large pharma industry-funded US study.
