JMJD6 and lung disorder: A transition in research hotspots is depicted in Figures 4D,E, where the initial focus was on the role of efferocytosis in the pathophysiological processes of various inflammatory diseases (especially cardiac and pulmonary diseases), resulting in bursts of the keywords “in vitro,” “phosphatidylserine receptor” and “apoptotic cell clearance.” With the gradual improvement in the understanding of the underlying mechanisms, research hotspots have also progressively turned to treatment methods, so “inflammation resolution” has recently become a popular topic.
