| Could leaky blood vessels in the brain be a culprit in Alzheimer’s disease? Posted: 10 Mar 2022 08:50 AM PST Researchers report that they found high levels of the protein Fli-1 in the brains of deceased Alzheimer's patients. Blocking Fli-1's action in a mouse model of Alzheimer's disease reversed mental loss and reduced the brain inflammation and amyloid-beta clumping that are hallmarks of Alzheimer's disease. Although clinical translation of this finding is likely years off, the study suggests Fli-1 is a promising therapeutic target for Alzheimer's disease. |
| Exploring ancient tuberculosis transmission chains Posted: 10 Mar 2022 08:50 AM PST Tuberculosis (TB) is the second most common cause of death worldwide by an infectious pathogen (after Covid-19), but many aspects of its long history with humans remain controversial. Researchers found that ancient TB discovered in archaeological human remains from South America is most closely related to a variant of TB associated today with seals, but surprisingly these cases were found in people who lived nowhere near the coast. This implies that these cases were not the result of direct transmission from seals, and instead one, or more, spillover events were likely to be the primary drivers of human infection. |
| Rear-end collision on the 'ribosome highway' Posted: 10 Mar 2022 08:50 AM PST As a molecular machine found in the cells of all organisms, the ribosome is responsible for making new proteins.
