Dr Li Zhang's group investigates bacterial species that cause gastrointestinal diseases and cancer and their interactions with the host immune system. They study bacterial genomes, bacterial virulence factors, host immune responses to bacterial pathogens, novel antimicrobial agents, and gut microbiota. Dr Zhang's earlier research was on autoimmune diseases.
Dr Li Zhang is a pioneering researcher in the field of human hosted Campylobacter species and inflammatory bowel disease (IBD). Dr Zhang hypothesized that some strains of Campylobacter concisus, a bacterium that usually colonises the human oral cavity, have enteric pathogenicity and are the initiator of a subgroup of human IBD. Research in Dr Zhang’s group has provided critical information to this emerging research field, including disease association, C. concisus natural colonisation site, C. concisus metabolic pathways and bacterial genomic features. They recently identified a novel C. concisus plasmid (pICON) and a novel toxin gene csep1, both are associated with active Crohn's disease (one type IBD), suggesting that pICON plasmid and csep1 gene are the potential bacterial markers for identification of virulent C. concisus strains that cause a subgroup of Crohn's disease. Patients with CD who carry pICON positive C. concisus strains are more likely to develop complications.
The second aspect of research in Dr Zhang's group is on the impact of microbes on immune regulation. Dr Zhang hypothesized that chronic infection and inflammation may impact on PD-L1/PD1 blockade therapy. https://doi.org/10.3389/fimmu.2018.00374 . This publication received high attention in the scientific community (current views rank top 94% and downloads rank top 92%). On-going research in Dr Zhang's laboratory is investigating the mechanisms by which different gut bacterial impact on immunotherapy.
