CD86 and acute respiratory distress syndrome: BDEP and DEP induced both M1 (CD86) and M2 (CD206) surface markers in MQ-ALI (Figure 2) The secretion of the cytokines TNF-α and IL-6 and the chemokine CXCL8 was unaffected in MQ-ALI in response to BDEP or DEP, and the levels of IL-1β, IL-10, and IL-12A were undetected.
