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.
-
NewsGum disease may lie at the root of some arthritis flare-ups
New research may help to explain why patients with gum disease are less likely to respond to rheumatoid arthritis treatments.
-
NewsResearchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.
-
NewsMicrobes that “eat together” may benefit from a shared immunological memory
A new study examines viruses that infect microbes in the deep sea and finds evidence that viruses interact with a far more diverse set of hosts than was previously thought.
-
NewsA healthy microbiome may prevent deadly infections in critically ill people
A study finds that gut microbiota and systemic immunity work together as a dynamic “metasystem,” in which problems with gut microbes and immune system dysfunction are associated with significantly increased rates of hospital-acquired infections.
-
NewsCommon cold gives children immunity against COVID-19
Researchers have identified memory T cells in children’s blood samples taken before the pandemic that react to cells infected with SARS-CoV-2, the virus that causes COVID-19.
-
NewsEngineered bacteria track down tumours, then signal the immune cells
Researchers have created a ’bacterial suicide squad’ that targets tumours, attracting the host’s own immune cells to the cancer to destroy it.
-
NewsFungal spores bind to lung cell protein to escape human defences
The pathogenic fungus Aspergillus fumigatus escapes elimination from surface cells of the human lung by binding to a human protein.

NewsGut microbes spur immune cells to mend damaged muscles
Researchers have found that gut microbes spur the production of a class of regulatory T cells that play a role in repairing injured muscles and mending damaged livers.
