IL-1β mRNA andprotein levels in the heart were also dramatically increased as early as 24hours after MI and remained significantly elevated above baseline levelsthereafter (Figure 2C and 2D).Therefore, we examined the synergistic effect of TLRs ligands and IL-1βacting with IL-23 on the proliferation of and IL-17A production fromγδT cells. Here, IL23A is linked to myocardial infarction.
