Increased life expectancy also comes with age-related diseases. But what causes one to age? Although there is no single answer, scientists at Duke-National University of Singapore (NUS) have shown in mice that interleukin-11 (IL-11) promoted aging. Blocking it improved health and lifespan.
The adaptation of cancer cells to therapies limits the effectiveness of treatments. However, understanding the mechanisms they use to do it could help reverse them or be used to design more powerful drugs. Scientists at New York University (NYU) have studied the transitions causing resistance and have observed how it develops through a gradual process they have called the “resistance continuum.”
Muscle fatigue associated with brain inflammation could be prevented by modulating certain cytokines. Researchers at Washington University in St. Louis (WUSTL) have studied inflammation in the CNS in infection models of Escherichia coli, SARS-CoV-2 and amyloid-β toxicity, unveiling its impact on motor function, the role of IL-6 in this process and how to mitigate it in chronic disease.
Patients with congenital hearing loss could benefit from a gene therapy currently in development. Although there are approaches that could reverse the process in children and young people before it becomes severe, so far, adults do not have any treatment that prevents the progressive deterioration of auditory sensory cells caused by this disease.

A new methodology based on the regulation of genetic enhancers has made it possible to develop a cellular map that reveals new types of helper T cells related to immunological disorders that could be explored for the development of new therapies. “I am very interested in the function of rare T cells, and I am trying to analyze their function by eliminating certain rare T cells with antibodies with ADCC [antibody-dependent cell-mediated cytotoxicity] activity or by disrupting genes that characterize rare T cells in animal models,” senior author Yasuhiro Murakawa told BioWorld.
Scientists at the University of Washington have engineered human plasma B cells modified to express long-lasting bispecific antibodies that could be used to treat leukemia without requiring continuous dosing.

“We are trying to engineer plasma cells to make as a stable source for biologic drugs. One thing that is really unique about plasma cells is that they can live for a really long time … up to 10 years or even 100 years depending on the type of plasma cell that that you make,” Richard James, senior author of the study, principal investigator at Seattle Children’s Research Institute, and associate professor at the University of Washington, told BioWorld.
Alzheimer’s disease (AD) is a neurodegenerative condition in which amyloid plaques and neurofibrillary tangles accumulate in the brain. In addition to genetic factors, DNA damage and epigenetic alterations also play a key role in the pathogenesis and progression of this disease, altering gene expression, the functioning and maintenance of brain cells. DNA double-strand breaks (DSBs) and chromatin accessibility are two hallmarks of AD whose study could reveal new ways of approaching this disease.
New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria.
