Antioxidants help tumour cells to suppress T cells. Reactive oxygen species turn out to be not merely harmful, but also necessary to mount the immune response against cancer.
Modified RNA overrides faulty protein stop signal
A chemically modified transfer RNA can bypass faulty stop codons and partially restore the function of the CFTR protein in models of cystic fibrosis.
Blood reveals the biological age of individual cell types
Not only organs, but also individual cell types appear to age at different rates. Proteins in blood plasma can help estimate that biological age and are associated with later disease and mortality.
A single amino acid change in an antibody explains a rare clotting disorder
A single amino acid change in an antibody against adenoviruses can trigger an immune response that causes a severe clotting disorder.
Universal respiratory vaccine shows promise in mice
A new vaccine that activates the innate immune system over a prolonged period offers mice broad protection against a range of respiratory infections.
Two faces of one enzyme in Alzheimer’s disease
Two variants of a single enzyme appear to play opposing roles in Alzheimer's disease, offering new leads for therapy and diagnostics.
Two breakthroughs in HIV therapy
The seventh person ever appears to have been cured of HIV by stem cell transplantation, and triple immunotherapy enables HIV patients to go without antiretroviral therapy for months at a time.
Wait — I must reuse the verbatim wording from the translation where it matches.
Immunotherapy has succeeded in allowing HIV patients to keep their infection under control temporarily. In addition, another patient has been completely cured of HIV by stem cell transplantation.
