The Immune System – News and Features
Study Reveals Extent of Brain Complications in Children Hospitalized With COVID-19
Although the risk of a child being admitted to hospital due to COVID-19 is small, a new UK study has found that around 1 in 20 of children hospitalized with COVID-19 develop brain or nerve complications linked to the viral infection.
Hollow DNA Nano-Objects Could Trap Viruses, Rendering Them Harmless
A research team has developed a new approach against viral infections: engulfing and neutralizing the virus with nano-capsules tailored from genetic material using the DNA origami method.
Immune System May Play a Role in Miscarriage
Researchers are closing in on how the immune system may play a role in miscarriage, which affects about a quarter of pregnancies.
Children With Mild COVID-19 Have Robust Antibody Responses Months Later
According to a study, children and adolescents who had mild to asymptomatic cases of COVID-19 were found to have robust antibody responses up to four months after infection.
Artificial Sweeteners Used as Carbon Monoxide “Couriers” To Treat Organ Injury
Carbon monoxide gas is toxic in large doses however it can have beneficial effects by reducing inflammation and protecting cells against injury. An oral prodrug has been developed by scientists that delivers carbon monoxide to protect against acute kidney injury
3D Model Shows How SARS-CoV-2 Infects Brain Cells
Researchers have created a three-dimensional stem cell model that demonstrates a potential route of entry of SARS-CoV-2 into the human brain.
Team Identifies Antibodies That Could Neutralize Many Norovirus Variants
Researchers have isolated a panel of human monoclonal antibodies from subjects with a history of acute gastroenteritis that neutralize a broad range of norovirus variants in laboratory tests.
Neuraminidase 3: A Potential Therapeutic Target for Colitis
Research has shown that the Neuraminidase 3 (Neu3) enzyme is responsible for the onset and progression of colitis, a chronic digestive disease caused by inflammation of the colon.
Pfizer COVID-19 Vaccine 78% Effective in Pregnant Women
In a new retrospective observational study, researchers from Tel Aviv and the US matched 15,060 pregnant women in Israel into vaccinated/unvaccinated pairs to determine the efficacy of the Pfizer COVID-19 vaccine. Their results show that vaccination with BNT162b2 in pregnant women significantly lowered the risk of SARS-CoV-2 infection, with an efficacy rate of 78%.
Genome of Photosynthetic Animals Decoded
Some sea slugs take up chloroplasts into their cells from the algae that they consume. These chloroplasts retain their ability to perform photosynthesis within the animal cells for several months and provide the sea slugs with nutrition. Genome analysis of photosynthetic sea slugs has revealed that chloroplast acquisition occurs without gene transfer.
