quick Summary

• Study Objective: Researchers analyzed lipid nanoparticle (LNP) delivery across multiple cell types in livers, spleens, and bone marrow of non-human primates (NHPs) under end-of-life (EoL) and control conditions to understand functional dynamics of LNP-mediated delivery systems.
• Cell Type Findings:

– Liver: Identified 15 cell types; Kupffer cells had highest transfection rates.
– Spleen: Analyzed 18 cell types; macrophages showed highest LNP uptake per cell.
– Bone Marrow: Found delivery effectiveness to hematopoietic stem/progenitor cells alongside myeloid cells in clusters of CD34+ markers.

• Key Associations:

– Lipoprotein receptors (LRP1, LDLRAD3, MSR1) correlated with more efficient LNP transfection across tissues. Import-related pathways like endocytosis were significant determinants replicated in multiple tissues.

• Hypotheses & Implications:

– Delivery mechanisms differ between mice and NHPs rather than being inherently harder for NHPs. Multiple receptors likely mediate particle uptake instead of exclusively targeting hepatocytes as previously presumed.
