Answer 2

Explanation:

The association between intestinal homeostasis and life span has caught the attention of the research community worldwide. There have been multiple evidences which support the role of gut homeostasis in aging. The Drosophila gastrointestinal tract is very similar to the mammalian gut, and therefore it can directly be used as a model to understand the association between gut microbiota, immune system, and aging in humans. In current review we have discussed the importance of gut microbiota in aging. Also we have highlighted the importance of host immune system and gut aging. Since the increased microbial load in the gut activates the host immune system, the dysregulated microbiota can have direct implications in gut aging. The proliferation and renewal of intestinal stem cells can also affect gut aging. Another important aspect that we have discussed is the communication between the gut and the other organ systems which affect the overall aging process. Altogether we propose that the Drosophila gut can be a good model to improve our understanding of human gut aging
