Supercentenarians have an abundance of cancer-killing immune cells
The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...

Early immune 'checkpoint' could help explain why the same virus affects individuals so differently
Age, genetics and lifestyle are known to influence how people respond to viral infections. Scientists also know that differences in immune responses play an important role, but exactly how these factors shape the course of ...

Single-gene edits fail to protect transplanted insulin-producing cells
In people with type 1 diabetes, the immune system mistakenly destroys the pancreatic beta cells responsible for producing insulin. Patients therefore require lifelong insulin therapy to regulate their blood glucose levels.

T cells ditch exhaustion marker to escape tumors and protect against cancer relapse
As the immune system battles cancer, chronic stimulation gradually drives T cells to a state of exhaustion. But some of these exhausted T cells can lose expression of the exhaustion marker LAG3, move out of the tumor and ...

An immune defect that may set Crohn's disease in motion
Crohn's disease, a condition characterized by widespread inflammation in the gut, may arise from a weakened immune response, according to new research from the University of Toronto's Temerty Faculty of Medicine.

Tsimané and Moseten peoples of lowland Bolivia demonstrate an intriguing case of epidemiological resilience
Despite widespread COVID-19 infection in the Tsimané and Moseten populations of Bolivia, the mortality rate in these remote Indigenous groups was the lowest ever recorded for any population or region.

Focusing on bodily sensations may dampen acute inflammation, human experiments suggest
We usually think of bodily sensations as information the brain receives. What if the way we attend to those sensations can feed back and change the biological response itself?

Immunotherapy found effective against a subtype of difficult-to-treat ovarian cancer
A research group has revealed through studies in humans and mice that a subset of clear cell ovarian cancers, which have been considered difficult to treat with anticancer drugs and immunotherapy, responds to immunotherapy.

Obesity weakens anti-tumor immune response in lung cancer, but exercise may restore it
Obesity can weaken the immune system's tumor-killing responses in lung cancer, leading to disease progression, but a new study by experts at Roswell Park Comprehensive Cancer Center reveals that exercise may reverse this ...

Booster vaccination strengthens existing defenses against newer COVID-19 variants
The SARS-CoV-2 genome is subject to constant mutations. Some of these mutations reduce the effectiveness of RNA-based vaccines, which consequently have to be adapted regularly. Until now, however, it was unclear how the immune ...

TLR2 links inflammation to neonatal heart regeneration, mouse study finds
Unlike adult hearts, the hearts of newborn mammals can temporarily regenerate after damage. However, this remarkable ability is rapidly lost within the first days of life. In a new study, scientists investigated how neonatal ...

New approach opens rare immune cells to genetic risk research
Much of how genetic risk leads to disease has remained hidden. In many cases, genetic variants linked to disease do not act on nearby genes along the chromosome. Instead, they influence genes located far away along the DNA ...
