Figure 1. The gut-lung axis.
A model showing the gut-lung axis and the gut microbiota's regulatory impact on lung function immune reaction by priming DCs and then proliferation and activation of T-cells in response to antigens. Gut dysbiosis results in impaired T-cell proliferation and activation, thus causing a reduction in lung immune reaction
DCs, dendritic cells; SCFA, short-chain fatty acids; LPS, lipopolysaccharides
