In addition, ATF3 facilitates the pathogen clearance in S. pneumoniae infection by promoting IL-17A production in γδ T cells (Lee et al., 2018), and it inhibits the secretion of inflammatory cytokines induced by Mycoplasma pneumonia in vitro and in vivo (Wang et al., 2017). Here, ATF3 is linked to Mycoplasma pneumoniae pneumonia.
