To be successful, CAR T-cells need a balance between being effective and overkill. Researchers from the University of Pennsylvania and Vittoria Biotherapeutics Inc. have eliminated the CD5 signaling pathway of their CAR Ts to prevent the immunosuppressive brake effect. In return, this improved their proliferation and antitumor activity in T cell lymphomas.

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 have shown in mice that interleukin-11 (IL-11) promoted aging. Blocking it improved health and lifespan.

Not all cancer cells that detach from the primary tumor and embark on a journey to another organ colonize it. To establish themselves, cells need specific conditions. Scientists at the Federal Institute of Technology Zurich (ETH Zurich) explored this hypothesis in the liver and identified a protein involved in metastatic transformation. Blocking it prevented liver metastasis. Their findings may have applications in other organs and various types of cancers.

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.
