Abstract
The molecular essence of the battle between host and pathogens lies in the protein-protein or protein-metabolite interactions. Itaconate is one of the most upregulated immunometabolites, regulating immune responses through either noncovalent binding or covalent modification in the host. We herein briefly review recent progresses in the discoveries of physiological and pathological roles of itaconate and applications of chemical proteomic technologies in exploring itaconate modifications on cysteines (S-itaconation) at the interface of host-pathogen interactions. Key challenges are also proposed as future outlook.

It consists of 6 issues per year covering the following 11 sections, each of which is reviewed once a year:
Host-microbe interactions: bacteria
Cell regulation
Environmental microbiology
Host-microbe interactions: fungi/parasites/viruses
Antimicrobials
Microbial systems biology
Growth and development: eukaryotes/prokaryotes
