NewsStudy reveals key differences in long-term brain effects of COVID-19 and flu
While both Covid and flu can leave lasting lung damage, only SARS-CoV-2 infection caused persistent brain inflammation and small blood vessel injury, even after the virus was no longer detectable, a new study has found.

NewsNew strategies aim at HIV’s last strongholds
A new study has overcome a long-standing challenge—how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease difficult to cure.

News Huayunuo approval positions China at forefront of viral hepatitis innovation, says GlobalData
Huahui Health has recently secured conditional approval from China for Huayunuo (Libevitug Injection), marking it as the first domestically developed monoclonal antibody (mAb) drug for chronic hepatitis D virus (HDV) infection in adults with or without compensated cirrhosis.

NewsNovel camel antimicrobial peptides show promise against drug-resistant bacteria
Researchers have identified three novel antimicrobial peptides (AMPs) from dromedary camels that effectively target multidrug-resistant bacteria, offering potential alternatives to conventional drugs.

NewsNew single-cell transcriptomic clock reveals intrinsic and systemic T cell aging in COVID-19 and HIV
Scientists developed a new single-cell transcriptomic clock called T immune cell transcriptomic clock (Tictock) to measure aging in specific immune cells. They found that in patients with acute Covid-19, the infection increased the biological age of naïve CD8 T cells.

NewsHoly Grail: One vaccine may provide broad protection against many respiratory infections and allergens
In a new study in mice, researchers have developed a universal vaccine formula that protects against a wide range of respiratory viruses, bacteria and even allergens.

NewsNew findings on infection with the Epstein-Barr virus
Researchers have identified genetic and non-genetic factors that help the body fight the Epstein-Barr virus. Using a new technique, they were able to estimate the amount of EBV in the blood and find correlations in large health data sets – for example, an increased viral load in people with HIV infections, but also in smokers.

NewsMissed opportunity: Study shows low vaccination rates among expectant mothers in Norway against COVID-19 and influenza
A study of over 50,000 pregnant women in Norway during the 2023/24 influenza season found that only 29.9% were vaccinated against influenza and 12.1% against COVID-19 during pregnancy, remaining far below recommended targets.

NewsResearchers discover how tuberculosis bacteria use a “stealth” mechanism to evade the immune system
New research reveals that mycobacteria release tiny packages called extracellular vesicles that fuse with the membranes of immune cells. These vesicles contain specialized lipids—fatty molecules—that make the cell membrane more rigid.

NewsPrenatal infection increases risk of heavy drinking later in life
Exposure to infection and other immune stress in the womb increases the likelihood of alcohol misuse in adulthood, a risk that may be reduced through prenatal antioxidant treatment, a new study shows.

NewsNovel vaccine protects against C. diff disease and recurrence
A novel vaccination approach cleared the harmful gut bacterium Clostridioides difficile in an animal model of infection. An experimental vaccine administered to the mucosal lining of the colon protected against illness, death, tissue damage and infection recurrence.

NewsGlobal scientific paper establishes first consensus definition of gut health
A global group of 13 scientists and clinicians is helping establish clarity by publishing a consensus definition of gut health. They define gut health as “a state of normal gastrointestinal function without active gastrointestinal disease and gut-related symptoms that affect quality of life.”

NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.

NewsCOVID-19 vaccination during pregnancy may help prevent preeclampsia
A new multinational study has found that COVID-19 vaccination during pregnancy, particularly when combined with a booster dose, significantly reduces the risk of preeclampsia, a serious and potentially life-threatening pregnancy complication.
-
NewsHow bacteria may promote breast cancer
Researchers have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known as spermine oxidase (SMOX).
-
NewsScientists develop first-of-its-kind antibody to block Epstein Barr virus
Using mice with human antibody genes, scientists have developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the Epstein Barr virus (EBV) from binding to and entering human immune cells.

NewsChildren with sleep apnea face higher risk of flu and COVID-19, new study finds
A five-year study has revealed that children with sleep apnea are twice as likely to contract the flu or COVID-19, regardless of their age or weight. Even after undergoing surgery to remove tonsils or adenoids, this increased vulnerability persists due to long-term changes in the immune system.

NewsNew antibody–drug conjugate strategy to block HIV infection
New antibody–drug conjugates (ADCs) combine a CD4 mimic with neutralizing antibodies for enhanced suppression of HIV infection. By targeting the gp120 on the viral envelope via a two-step mechanism, the ADCs effectively block viral entry.

NewsNew biosensor offers early warning system for disease
Researchers have developed a tissue-adhesive sensor for real-time oral health monitoring to combat long-term issues such as gum disease and tooth loss.

NewsGut microbiome may be the link to gluten sensitivity without celiac disease
Researchers found that after antibiotic treatment, mice exposed to gluten had changes in the bacteria living in the gut. These shifts in bacteria types altered how they processed carbohydrates, fats and sugars which may influence how these nutrients are recognized by the immune system.
