A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

The study of health-beneficial effects that probiotic bacteria can exert on humans and animals is at its beginning. Pending scientific questions include the identification of molecular markers of the health-promoting activity of specific strains, which may be used to select novel probiotic strains and to gain understanding of the mechanisms underlying their effects. In that perspective, the role of bacterial proteins must be evaluated, placing proteomics-based approaches at the core of the field. Until now, most proteomic analyses focused on the dynamics of abundant cytoplasmic proteins during adaptation of bacteria to conditions mimicking the gastro-intestinal tract environment. The development of in silico and experimental procedures allowing identification and quantification of surface-exposed and secreted proteins should boost our understanding of bacteria-host crosstalk.
