Molecules known as tRNAs are often overlooked in studies of disease processes. Researchers have found that a mutation in a tRNA gene called n-Tr20 -- expressed only in the brain -- can disrupt the landscape of entire cells, leading to chain reactions that alter brain function and behavior.

Tethering together type 2 diabetes drugs increases efficacy of combination therapy

Biomedical engineers have shown that the effectiveness of a two-pronged type 2 diabetes treatment increases when the drugs are linked by a heat-sensitive tether rather than concurrently administered. The combination molecule forms a gel-like depot under the skin that slowly releases the drug. These findings suggest that this approach to combination drug design could be applied to disease therapies beyond diabetes.

If the mist in a dentist's office -- sent flying into the air by spinning, vibrating tools -- contains a virus or some other pathogen, it is a health hazard.

Early NK cell-mediated immune response may contribute to severe COVID-19

Researchers may have come one step closer toward understanding how the immune system contributes to severe COVID-19. In a new study, researchers show that so-called natural killer (NK) cells were strongly activated early after SARS-CoV-2 infection but that the type of activation differed in patients with moderate and severe COVID-19. The discovery contributes to our understanding of development of hyperinflammation in some patients.

Future mental health care may include diagnosis via brain scan and computer algorithm

Most of modern medicine has physical tests or objective techniques to define much of what ails us. Yet, there is currently no blood or genetic test, or impartial procedure that can definitively diagnose a mental illness, and certainly none to distinguish between different psychiatric disorders with similar symptoms. Experts are combining machine learning with brain imaging tools to redefine the standard for diagnosing mental illnesses.

A new treatment concept for age-related decline in motor function

A research group conducted experiments using aged mice to demonstrate that muscle denervation at the neuromuscular junction (NMJ, *1) could be appreciably offset by an NMJ formation-enhancing treatment that strengthened the motor function and muscle of aged mice. The results of this study suggest that NMJ formation-enhancing treatment may be effective to overcome motor impairment and muscle weakness associated with human aging.

Realtime observation of structural dynamic of influenza A hemagglutinin during viral entry

Unlike living organisms, to avoid extinction, viruses need to hijack living host machineries to generate new viruses. The devastating respiratory virus, influenza A virus, utilize its hemagglutinin (HA) proteins to search for suitable host cells. Generally, HA has two important functions: selection of host cell and viral entry. Upon attaching to host cells, Influenza A virus are brought into host cells via endocytosis. A lipid bilayer cargo, known as endosome, carries influenza A virus from cell membrane into cytoplasm of host cell. Although the environment inside endosome is acidic, influenza A virus remains alive. More strikingly, HA undergoes structural change to mediate viral membrane to fuse with host endosomal membrane to form a hole in order to release viral components.
