Session 2B: Assessing the Implications of Oligonucleotide Uptake into Cells
Session Chair(s)
Xuan Chi, PhD
Supervisory Pharmacologist
CDER, FDA, United States
This session will examine the cellular uptake and lysosomal processing of single-stranded oligonucleotides by the most frequently affected tissues and cells following systemic administration (kidney and macrophages) and intrathecal administration (neurons). The histopathologic changes associated with uptake will be presented and discussed relative to assessing adversity of the findings. The conclusion of the European Society of Toxicologic Pathology (ESTP) expert panel on adversity of lysosomal accumulation relative to oligonucleotides will also be discussed.
