ALT A study design diagram illustrating a research project involving 171 young adults. It includes sections on multi-omics, showing aspects like body temperature, demographics, lifestyle, and analyses of DNA, RNA, proteins, and metabolites from serum. Blood and feces samples are collected, and daily temperature is measured. A graph compares body temperature over time, indicating high versus low fever, with notes on inflammation and microbiome flagellin levels. The summary shows a flagellated microbiome, flagellin receptors, and fever, highlighting interactions with the immune system.
