Atibuclimab (IC14) for Treatment of Acute Decompensated Heart Failure: A Phase Ib Pilot Study. (PubMed, JACC Basic Transl Sci) - "Treatment was associated with sustained CD14 receptor occupancy, reduction in systemic inflammation, lower natriuretic peptide levels, and improvement in left ventricular ejection fraction. These findings support the safety and biologic activity of CD14 blockade in acute decompensated heart failure and provide a rationale for progression to randomized phase II clinical trials."

CD14 Blockade Modulates Macrophage-Mediated Immunological Injury in a Translational Model of Reperfused ST-Segment Elevation Myocardial Infarction. (PubMed, JACC Basic Transl Sci) - "Multiomic studies suggest CD14 blockade downregulated macrophage-specific proinflammatory and tissue-wide remodeling processes without suppression of monocyte-macrophage infiltration or repair. These findings support a clinically practicable targeted immunomodulatory strategy of CD14 blockade initiated at reperfusion to prevent chronic immunological progression toward ischemic heart failure, and provide new insights into the pleiotropic roles of CD14 in inflammation and myocardial injury."

CD14-dependent MAP kinase signaling is required for pathogenic neutrophil extracellular trap formation in APS (ACR Convergence 2025) - "Neutrophil CD14 appears to be required for the p38 MAPK-mediated neutrophil activation and NETosis reliably triggered by anti-β2GPI in APS. This work identifies neutrophil surface CD14 and downstream p38 MAPK signaling as novel therapeutic targets with the potential to restrain not only thrombosis, but also the upstream inflammation that underlies APS."
