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.

NewsBoosting gut microbiota helps healing after colorectal cancer surgery
Researchers have shown for the first time in mice that modifying intestinal flora before surgery could reduce postoperative complications in colorectal cancer patients.
-
NewsPseudomonas aeruginosa produces molecule that paralyzes immune system cells
Researchers in France have discovered a mechanism that likely contributes to the severity of Pseudomonas aeruginosa infections, and could be a target for future treatments.

CareersThe Kulkarni Lab
The Kulkarni Lab works to determine how locally derived complement proteins in the lung can be harnessed to reduce the burden of end-stage lung disease.

NewsClinicians ID severe form of mpox with high mortality in people with advanced HIV
An international collaboration of clinicians has identified a severe, necrotising form of mpox with a high mortality in immunosuppressed people living with HIV.

NewsMicrobiota from mum regulates lung immunity in newborns
Researchers have discovered that a type of white blood cells, the γδ T cells, influences the transfer of maternal microbiota during birth and nursing, and impacts the lung immune response in newborns.

NewsCellular evidence reveals why men are at higher risk from COVID-19
Researchers from Osaka University provide cellular evidence for the observed differences between the response to COVID-19 infection in male and female patients.

NewsViruses that kill cancer cells show promise for triple-negative breast cancer when combined with chemo
Researchers have shared positive results from a phase 2 clinical trial of an oncolytic virus combined with standard chemotherapy in patients with early stage triple-negative breast cancer.

NewsStudy IDs bacterial weapons that could be harnessed to treat human disease
The discovery of ancient immune-fighting machinery in human cells that is derived from bacteria paves the way toward more ‘CRISPR’-like technologies, researchers say.
-
NewsME linked to changes in the gut microbiome and metabolites
Two studies have found that myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is associated with reduced levels in the gastrointestinal microbiome of microbes known to produce the fatty acid butyrate, disruptions that could explain in part how the immune system becomes disrupted in people with ME/CFS.

NewsSilent flagellin delivers insights into how gut bacteria evade the immune system
Researchers from the Max Planck Institute for Biology Tübingen have identified a new type of flagellin in the human gut, termed ‘silent flagellin’, that binds to the immune receptor Toll-like receptor 5 without inducing a pro-inflammatory response. Their work addresses the long-standing question of how benign gut microbes evade the ...

NewsCannabis shows potential as weapon in the fight against COVID-19
Cannabis could become an important weapon in the battle against Covid-19, with a new review suggesting both cannabinoids and terpenes show great promise in lab research, due to their antiviral qualities.

NewsGut bacteria can impact immune cells that damage brain tissue
Gut bacteria affect the behaviour of immune cells throughout the body, including ones in the brain that can damage brain tissue and exacerbate neurodegeneration in conditions such as Alzheimer’s disease, according to new research.
-
NewsThree compounds from sea sponge and marine bacteria offer Covid-blocking powers
University of British Columbia researchers have identified three compounds that prevent COVID-19 infection in human cells, derived from natural sources including a BC sea sponge.

NewsPoor gut health may drive multiple sclerosis — but better diet may ease it
Researchers have traced a previously observed link between microscopic organisms in the digestive tract — collectively known as the gut microbiome — and multiple sclerosis (MS).

NewsGut microbiome responds to nanomaterial graphene oxide as if it were a parasite
The nanomaterial graphene oxide—which is used in everything from electronics to sensors for biomolecules—can indirectly affect the immune system via the gut microbiome.
