Lymphatic Endothelial Cells Produce Chemokines in Response to the Lipid Nanoparticles Used in RNA Vaccines
In this study, SM-102, an ionizable lipid that is used in the approved RNA vaccine for the clinical usage of COVID-19 mRNA vaccine, was used. Immortalized mouse lymphatic endothelial cells (mLECs) or professional antigen presenting cells (APCs) such as RAW 264.7 monocyte/macrophage cells were incubated with LNPs that contained no mRNA. As a result, chemokines involved in the recruitment of monocytes/neutrophils were produced only by the mLECs following the LNP treatment. These findings indicate that LEC appear to serve as the cell that sends out initial signals to response LNPs.PMID:38538323 | DOI:10.1248/bpb.b23-00689
