NewsProteins in breast milk found to be essential for a baby’s healthy gut
A new study shows variation in the protein composition of breast milk between mothers explains much of the variation in the abundance of key beneficial microbes in the gut of their babies.
-
NewsHypervirulent bacteria emerging in healthy people
New ’hypervirulent’ strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting researchers to investigate how the human immune system defends against infection.
-
NewsStudy IDs secret of stealthy invader essential to ruinous rice disease
The virulence of a rice-wrecking fungus — and deployment of ninja-like proteins that help it escape detection by muffling an immune system’s alarm bells — relies on genetic decoding quirks that could prove central to stopping it.
-
NewsEnergy depleting mechanism immunizes bacteria against phages
Researchers have described a new family of proteins that deplete cells of their energy, thereby protecting the cells from invaders. The previously unknown immune mechanism is used by many living creatures, from bacteria to bees.
-
NewsCommon cold virus exposure may help usher in immunity to Covid
Exposure to common cold-causing coronaviruses may contribute to pre-existing immunity to COVID-19, according to a new study.
-
NewsSpike protein mutants with low binding affinity usher in new Covid vaccine
Researchers have succeeded in producing a new vaccine against the SARS-CoV-2 coronavirus by identifying spike protein mutants that lack binding affinity.
-
NewsInterferon could help reduce the spread of COVID-19
Results of an innovative clinical trial have shown that the drug interferon could help reduce the spread of COVID-19 from a positive person to their household contacts, with the study helping to inform treatment options for a future pandemic.
-
NewsImmune systems develop ‘silver bullet’ defences against common bacteria
Immune systems develop specific genes to combat common bacteria such as those found in food, new research shows.
-
NewsHigh-res map of the human placenta reveals COVID virus hideouts
Researchers have developed a high-resolution map of the human placenta visualizing an array of different immune microenvironments in healthy placentas from uninfected pregnancies, and those from pregnancies affected by COVID infections.
-
NewsResearchers reveal how Leishmania parasite uses immune cells as Trojan Horse
A new study found that the parasite targets a receptor on the surface of the neutrophil to gain access to the cell, and once inside the parasite resists the neutrophils’ pathogen-killing molecules.

NewsLupus flare-ups linked to Ruminococcus blautia gnavus blooms in gut
A new study found that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period.

NewsEngineered lung cells light up when Covid sparks immune response
Scientists have engineered lab-grown lung epithelial cells to light up red in colour once they launch an immune response, creating a tool that can be used to screen for drugs that can help treat COVID-19 and other emerging infections.
-
NewsFungal infections are an unintended consequence of advanced immunotherapy
Researchers have shown how clinical use of some monoclonal antibodies may cause life-threatening systemic fungal infections.
-
NewsNew research shows HIV can lie dormant in the brain
Researchers in the UNC School of Medicine extracted living brain tissue to conclude that specialized immune cells in the brain can harbour latent but replication-competent HIV.
-
NewsVirus aids breakthrough in glioblastoma treatment
Scientists have reported a breakthrough in glioblastoma treatment following a recent clinical trial that used a modified cold virus injected directly into the tumor.
-
NewsEngineered virus with immunotherapy safe and improves cancer outcomes
A new study validates the safety of a combination approach using an engineered virus and immunotherapy to target an aggressive brain cancer, and offers promise to adapt treatment strategies.
-
FeaturesA new frontier in Zika vaccine development
A milestone achievement for science in combating the Zika virus as a new vaccine trial begins in the UK.
-
NewsTumour bacteria can trigger anticancer response
A novel approach to treating cancer uses bacteria that naturally reside within tumours to trigger a powerful anticancer immune response.
-
NewsBCG does not protect health workers against Covid
A world-leading international trial into the immune boosting benefits of the tuberculosis vaccine, BCG, has found it does not protect healthcare workers against COVID-19.
-
NewsGut bacteria could be behind weaker immune responses to COVID-19 vaccine
Digestion of fucose sugar by bacteria in our digestive tract could be hampering how effectively we respond to the COVID-19 mRNA vaccine.
