Mammalian gut immunity.
Level 5 - mechanism / opinion, no new human data
Narrative review without systematic methodology or primary empirical data
PubMed 25163502 · doi:10.4103/2319-4170.130922
What was done
This is a narrative review detailing the cellular composition of the mammalian intestinal immune system (hemopoietic and non-hemopoietic cells) and its bidirectional communication with the gut microbiota.
What was found
No quantitative findings or empirical data are reported in the abstract. The review conceptually describes how innate and adaptive immune branches cooperate to sustain microbial homeostasis, and notes that immune disruption leads to dysbiosis, inflammation, and metabolic diseases.
Why it matters
It synthesizes the conceptual link between mucosal immune regulation, intestinal microbiota homeostasis, and the development of metabolic disorders.
Limits
As a narrative review, it presents no original experimental or clinical data, no systematic search methodology, and no sample sizes.
