Clinical studies have shown that periodontal disease with Aggregatibacter actinomycetemcomitans can exacerbate symptoms of rheumatoid arthritis (RA), but the molecular mechanisms behind this remain unclear. In a recent study, researchers conducted several experiments in a mouse model of arthritis to shed light on this topic. Their findings reveal the crucial role of macrophages and the protein caspase-11 in this context, hinting at promising therapeutic targets for RA and other periodontal infection-related diseases.

There are some pretty strange ingredients in cosmetics and skin care products. One example is snail mucin -- also known as snail slime -- which is used for its moisturizing and antioxidant properties. But researchers might have found something even weirder to put on your face: molecules made by fish gut bacteria. In cultured cells, the compounds had skin-brightening and anti-wrinkle properties, making them potential ingredients for your future skin care routine.
