What is Multi-Omics?
Multi-omics refers to the comprehensive approach of integrating various
omics technologies such as genomics, transcriptomics, proteomics, metabolomics, and more. These technologies collectively offer a holistic view of the molecular mechanisms underlying biological processes and diseases, including infectious diseases.
How Can Multi-Omics Be Applied to Infectious Diseases?
Infectious diseases are complex, involving interactions between
pathogens, hosts, and environmental factors. Multi-omics can dissect these interactions at various biological levels. For instance,
genomics can unravel pathogen genetics,
proteomics can profile protein interactions, and
metabolomics can analyze metabolic changes during infection.
