NewsBacteria-enhanced graphene oxide nanoparticles for triple-action tumor eradication
Researchers developed graphene oxide nanoparticles that combine chemotherapy, immune activation, and photothermal heating to effectively destroy tumors. The novel GO nanocomposite is enhanced with bacterial components.

NewsResearchers discover way to predict treatment success for parasitic skin disease
Researchers have discovered a way to predict whether a patient suffering from cutaneous leishmaniasis will respond to the most common treatment, potentially saving patients from months of expensive, ineffective and toxic medication.

NewsMolecular stool test could improve detection of tuberculosis in adults with HIV
A prospective multicentre study highlights the potential of the Xpert MTB/Ultra stool test for diagnosing tuberculosis in people living with HIV.

NewsMolecules that fight infection also act on the brain, inducing anxiety or sociability
New research on a cytokine called IL-17 adds to growing evidence that immune molecules can influence behavior during illness.

NewsResearchers reveal why young plants may be more vulnerable to disease
A new study on baby plants shows that fighting disease at a young age often comes at a steep cost to growth and future evolutionary fitness—or their ability to reproduce.

NewsAlternative approach to Lyme disease vaccine development shows promise in pre-clinical models
An international research team finds genetically engineered Lyme bacterial proteins could offer long-standing protection against infection while requiring fewer vaccinations.

NewsWestern diet causes inflammation, traditional African food protects
A study showed that traditional African diets, rich in fiber, fermented food and vegetables, have higher health benefits that boost immunity and reduce the risk of developing lifestyle diseases, compared to the high calorie and high saturated fats in the Western diet.

NewsmRNA-based COVID-19 vaccines train the ‘long-term memory’ of the innate immune system
A study showed that vaccination of multiple mRNA-based COVID-19 vaccines could induce persistent epigenetic changes in innate immune cells, leading to long-term immune responses for SARS-CoV-2 and other pathogens.

News‘It’s a shot, not a vaccine like MMR’: New skepticism prompts call for action
This ‘vaccine is not a vaccine’ is a new, previously unreported type of vaccine-specific scepticism, and it arose only during the COVID-19 pandemic. However, it might, according to the researchers, also apply to the flu vaccine.

NewsSusceptibility to bovine TB in cattle traced to key genes
A new study identifying genetic factors contributing to bovine tuberculosis (bTB) susceptibility has found several key genes and pathways involved in the bovine response to Mycobacterium bovis, the causative agent of the disease in cattle.

NewsNewer hepatitis B vaccine shows promise as booster for health care workers
A new study compares the effectiveness of Heplisav-B, a new hepatitis vaccine, vs. standard hepatitis B vaccines as a booster in previously vaccinated individuals.

NewsBreaking antibiotic-resistant bacteria’s protective shields opens door for immune system response
Researchers have made progress in uncovering how Streptococcus pneumoniae constructs its capsule, which serves as a protective shield. This capsule is a primary target for vaccine development.

News‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants
A universal vaccine for coronaviruses removes sugar molecules from an area of a coronavirus spike protein that rarely mutates and creates effective and plentiful antibodies to inactivate the virus.
-
NewsA high-fat diet may impair response to infection
A new study in The Journal of Immunology reveals how a high-fat diet may impair the immune system’s ability to respond to infection by impacting the function of neutrophils, one of the first immune cells to respond to bacteria or viruses. The study demonstrated that male mice fed a high-fat ...

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.

NewsImmature platelet fraction offers clinical predictor for enhanced platelet recovery in patients with dengue fever
Immature platelet fraction (IPF) is recognized as a marker for thrombopoiesis, but a new study indicates that IPF% can be utilized as a predictor of platelet increase in patients with dengue infection.
-
NewsNIH-sponsored trial of Lassa vaccine opens
A National Institutes of Health (NIH)-sponsored clinical trial of a candidate vaccine to prevent Lassa fever has begun enrolling participants at the University of Maryland School of Medicine, Baltimore.

NewsCOVID-19 pandemic worsened mother and infant birth outcomes
Mothers who became pregnant after the start of the pandemic, those who experienced moderate-to-severe infections during pregnancy, and those who had infections during the third trimester were more likely to have adverse outcomes.

NewsThe relationship between gut microbiota, immunoglobulin A, and vaccine efficacy
Researchers concluded that the close relationship between immunoglobulin A (IgA) deficiency and the gut microbiota overgrowth is closely tied with the pneumococcal vaccine effectiveness in adults, thus providing insights for preventative strategies to enhance the vaccine response.

NewsCOVID-19 discovery opens door to new treatments for chronic lung problems
A discovery was made to understand how severe viral infections, like COVID-19 and flu could destroy the ability of immune cells to repair the tissue damage in lungs, causing long COVID and other chronic lung diseases.
