A novel cell therapy approach using cord blood-derived natural killer (NK) cells pre-complexed with AFM13, or acimtamig, a CD30/CD16A bispecific antibody, was safe and generated strong response rates for patients with refractory CD30-positive lymphomas, according to a new study.

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers show that the emergence of resistance can be understood in the mechanism of how bacteria build up defenses against being infected by viruses. It is about genes in the bacterium that interfere with the attacking virus's ability to multiply.

Scientists say they have found a pattern of so-called epigenetic 'marks' in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary 'memory' of those cancer-linked marks.

Drug-carrying DNA aptamers can deliver a one-two punch to leukemia by precisely targeting the elusive cancer stem cells that seed cancer relapses, researchers report. The aptamers -- short single-strand snippets of DNA that can target molecules like larger antibodies do -- not only deliver cancer-fighting drugs, but also are themselves toxic to the cancer stem cells, the researchers said.

Researchers developed a manufacturing technique that rapidly generates large quantities of nanoparticles coated with drug-delivering polymers, which hold great potential for treating cancer. The particles can be targeted directly to tumors, where they release their payload while avoiding many of the side effects of traditional chemotherapy.

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ultrasound to reveal capillaries and cells across living organs -- something that wasn't possible before.
