Dopaminergic neuronal regulation determines innate immunity of Caenorhabditis elegans during Klebsiella aerogenes infection.

The innate immune signals are the front line of host defense against bacterial pathogens. Pathogen-induced harmful effects, such as reduced neuronal signals to the intestine, affect the host's food sensing and dwelling behavior. Here, we report that dopamine and kpc-1 signals control the intestinal innate immune responses through the p38/PMK-1 MAPK signaling pathway in C.

A combination of ellagic acid and tetracycline inhibits biofilm formation and the associated virulence of Propionibacterium acnes in vitro and in vivo.

Propionibacterium acnes is an opportunistic pathogen which has become notorious owing to its ability to form a recalcitrant biofilm and to develop drug resistance. The current study aimed to develop anti-biofilm treatments against clinical isolates of P. acnes under in vitro and in vivo conditions.
