Using customized 'mini-antibodies' to mitigate chronic inflammation

Researchers at the Universities of Bonn and Sao Paulo have succeeded in mitigating chronic inflammation in mice using customized "mini-antibodies."

NTNU researcher explores how kids are affected by coronavirus, RS virus and rhinovirus

For two years now, the novel coronavirus SARS-CoV-2 has ravaged populations the world over. Some researchers believe that the virus will mutate toward less harmless variants.

COVID-19 vaccine reduced the risk of hospitalizations in children during the Omicron period

Results of a new multicenter study published in the New England Journal of Medicine found that vaccination with a primary series of the Pfizer-BioNTech mRNA COVID-19 vaccine reduced the risk of COVID-19-associated hospitalizations in children ages 5–11 years by two-thirds during the Omicron period.

New, longest documented case of persistent acute SARS-CoV-2 infection

Researchers describe a 16-month-old case of SARS-CoV-2 infection in an immunocompromised individual.

New study pinpoints how immune checkpoint protein LAG3 modulates T cell activity

Fighting cancer and chronic disease is tiring work for the immune system. When T cells are engaged in this kind of lengthy battle, they can become exhausted, or unable to function properly.

Study examines how race and sex influence tacrolimus pharmacokinetics in kidney transplant recipients

Kidney transplant survival is shorter, on average, in Black recipients compared to white recipients receiving similar treatment.

Noninvasive sound technology could lead to improved cancer outcomes in humans

Noninvasive sound technology developed at the University of Michigan breaks down liver tumors in rats, kills cancer cells and spurs the immune system to prevent further spread—an advance that could lead to improved cancer outcomes in humans.

New insight into lymphoid cell maturity could pave the way for more effective IBD treatments

A research group at Karolinska Institutet in Sweden has analyzed how certain immune cells known as innate lymphoid cells (ILCs) develop into mature cells that play a part in inflammatory bowel disease (IBD).

Intensity and longevity of SARS-CoV-2 vaccination response in patients with immune-mediated inflammatory disease

Researchers investigated the longevity and intensity of the SARS-CoV-2 vaccine immune response in patients suffering from immune-mediated inflammatory diseases.

Breakthrough finding reveals how male sex hormones contribute to cancer-related sex bias

Patients with cancers stemming from non-reproductive organs, such as bladder and liver cancer, have striking discrepancies in incidence, progression, response to treatment and survival outcomes depending on their sex. In almost all cases, male patients have worse prognoses and outcomes.

Comparison of neutralizing antibody response following SARS-CoV-2 booster vaccination with breakthrough infection

A new study examined the serological immune responses and antibody-dependent cell-mediated phagocytosis in individuals who had either received two doses of a standard vaccine regime, a booster dose following the regime, or a breakthrough infection following vaccination.

Researchers track COVID-fighting antibodies after vaccination

The antibodies generated by Pfizer's COVID-19 vaccine rise more slowly and decline more quickly than those generated by the Moderna vaccine, according to a new study from UVA Health.

Effects of COVID-19 treatment best with combination therapy

There is a steadily growing arsenal of drugs for COVID-19. Researchers from Charité – Universitätsmedizin Berlin, the Max Delbrück Center for Molecular Medicine (MDC) and Freie Universität (FU) Berlin have studied the mechanisms of action of antiviral and anti-inflammatory drugs.

Scientists discover differences in interaction of T-cells within tumor microenvironments

A team led by Northwestern Medicine investigators has discovered differences in the distribution and interaction of T-cells within the microenvironment of different regions of both brain tumors and brain metastases, according to findings published in the journal JCI Insight.

New data-driven mechanistic approach can help reduce drug costs and treat diseases

A new data-driven mechanistic approach that predicts cell types within tissue will help to reduce drug costs and treat diseases that were difficult to develop drugs for, according to a West Virginia University scientist.

People with COVID-19 can shed viral RNA in their feces months after initial infection

The extended presence of viral RNA in feces, but not respiratory samples, along with the association of fecal viral RNA shedding with GI symptoms suggest that SARS-CoV-2 infects the GI tract, and that this infection can be prolonged in a subset of individuals with COVID-19.

Mayo Clinic researchers devise a combination approach to more effectively target solid tumors

Researchers at Mayo Clinic's Center for Individualized Medicine have devised an immunotherapy technique that combines chimeric antigen receptor-T cell therapy, or CAR-T cell therapy, with a cancer-killing virus to more effectively target and treat solid cancer tumors.

UCL researchers boost the effectiveness of therapeutic vaccine for chronic HBV

Scientists at UCL have significantly boosted the effectiveness of a therapeutic vaccine designed to control chronic hepatitis B (HBV) infection, after uncovering and thwarting 'the enemy within'.

A kind of kiss between cells plays key role in the fight between immune system and blood cancer cells

Researchers at The Ottawa Hospital and the University of Ottawa have discovered that a kind of kiss between cells, called trogocytosis, plays a key role in the battle between the immune system and blood cancer cells.
